Zebra Mussels Documented in Lewisville Lake

Boaters urged to clean, drain and dry

AUSTIN – Less than a year following the discovery that zebra mussels had established a population in Lake Ray Roberts, the destructive invasive species has been confirmed in Lewisville Lake by the United States Geological Survey (USGS). This is the third lake in Texas, and the second within the Trinity River basin, where zebra mussels have been discovered.

Christopher Churchill, a biologist with the USGS who has been monitoring for zebra mussels in North Texas rivers and reservoirs, discovered the live juvenile on a settlement sampler near the dam.

Churchill indicated that this latest infestation is likely the result of contaminated boats being transported to Lewisville Lake, but it could be the result of downstream transport of zebra mussels from Lake Ray Roberts via Elm Fork of the Trinity River. Also, this latest infestation appears to be relatively new as no additional specimens have been documented.

The USGS, Texas Parks and Wildlife Department, University of Texas-Arlington and others continue to closely monitor for the spread of zebra mussels in Texas.

Zebra mussels can have economic and recreational impacts in Texas reservoirs. They can clog public-water intake pipes, harm boats and motors left in infested waters by covering boat hulls and clogging water-cooling systems, annoy boat-dock owners by completely covering anything left under water and can make water recreation hazardous because of their razor-sharp edges.

With Lewisville Lake being such a popular boating destination there is a heightened risk of zebra mussels being transported to non-infested lakes by boaters. However, the spread can be slowed by making sure boats that operate in zebra mussel-infested waters are not used in any other body of water until they have been cleaned, drained and dried. In addition, TPWD adopted rules regarding the transfer of zebra mussel larvae in water from lakes Texoma, Lavon, Ray Roberts and Lewisville. To comply with these rules, boaters and anglers need to drain all water from their boats (including live wells) before leaving those lakes.

From the environmental perspective, zebra mussels are filter feeders, which mean they compete with baitfish such as shad for available forage. Any impact on baitfish in turn can affect their predators — game fish such as bass, striped bass and catfish. Zebra mussels are also very harmful to native mussel populations because they will colonize on their shells and essentially suffocate them.

TPWD Executive Director Carter Smith emphasized that the discovery underscores the importance of boaters helping to prevent the spread of zebra mussels, which can be unknowingly spread when boats and trailers are moved from lake to lake.

TPWD and a coalition of partners have been reaching out to boaters in Texas with an advertising campaign to educate them not to transport the tiny mussels or their microscopic larvae, which are invisible to the naked eye and can stay alive inside livewells, bait buckets and other parts of the boat for up to a week. These partners include: North Texas Municipal Water District, Tarrant Regional Water District, Trinity River Authority, City of Dallas Water Utilities Department, Upper Trinity Regional Water District, Sabine River Authority, Canadian River Municipal Water Authority, San Jacinto River Authority, Brazos River Authority, City of Grapevine, City of Houston, City of Waco and Lady Bird Johnson Wildflower Center.

“With this somber news, I hope Texas boaters will always remember to “Clean, Drain, Dry” their boats, trailers and gear because all it takes is one instance of not properly cleaning to introduce this highly invasive and unwelcome species to a water body in Texas; and once they are established there is no known way to get rid of them,” Smith said.

Originally from the Balkans, Poland and the former Soviet Union, zebra mussels found their way to the Americas in the 1980s via ballast water of a ship. The small invaders were first found in 1988 in Lake St. Clair, Mich., and are currently known to have infested 29 states and more than 600 lakes or reservoirs in the United States.

Anyone wishing to receive a supply of informational brochures, wallet cards or posters about zebra mussels to distribute to boaters around lakes Lewisville, Ray Roberts or Texoma, please contact marketing@tpwd.state.tx.us. For more information regarding zebra mussels visit www.texasinvasives.org.

they are in several of the north texas lakes, TP$W will not admit it yet. part of the problem is the fishermans boats, the rest is natural wildlife transporting them, which we have no control over.

I think the wildlife is probably the largest transporter of these little rascals. Plus, it would seem the municipal water districts are the one's who really hate them, because they have to clean their water pipe inlets/outlets more often....other than that, they really do improve water clarity.

I have often wondered if they can improve our water quality, as well. Sort of a natural way to filter man induced pollution. Seems every one is so negative about them, the environmental benefits from having them around are being overlooked. Just saying...maybe we SHOULD be studying their BENEFITS to mankind....

Zebra mussels do clarify the water, which seems like a good thing, but there are consequences of that, as discussed below. Of concern to boat and lakeside property owners is the fact that they settle in large numbers on anything left in the water and can do considerable damage. Evidence in the Great Lakes shows that zebra mussels can decrease the amount of food available for fish, which could translate into poorer fishing in the future. Texas has not had zebra mussels long enough for all the impacts to become known, but eventually we will find out.

ZEBRA MUSSELS CHANGING GREAT LAKES ECOSYSTEM

In a just-published series of scientific papers, university researchers and scientists from the Great Lakes Environmental Research Laboratory in Ann Arbor, Mich., have documented basic changes in the food chain in zebra mussel-infested waters of Lake Huron's Saginaw Bay that threaten water quality and healthy fisheries across the Great Lakes ecosystem. The lab is run by the Commerce Department's National Oceanic and Atmospheric Administration.

In general, the research shows an alarming shift in how energy and nutrients are routed through the food chain. Results show that Saginaw Bay's energy base is no longer dominated by phytoplankton because these microscopic, free-floating plant cells are choice food for zebra mussels, which are able to selectively filter the cells out of the water.

The spread and growth of zebra mussels have decimated this important free-floating part of the food chain, raising concerns that all of the bay's fish stocks may suffer.

Zebra mussels are also encouraging growth of harmful blue-green algae by rejecting them as food, thus giving them a competitive advantage over less abundant algae that are eaten by the mussels. The mussels may also release nutrients that encourage algae growth, especially blue-green algae.

This in addition to a sudden change from a free-floating to a bottom-dominated food base may force scientists and decision- makers to reassess current models used to guide the management of water quality, fisheries and toxic contaminants throughout the Great Lakes region.

###
BACKGROUND INFORMATION

Zebra Mussels in Saginaw Bay
Saginaw Bay was studied because it serves as a ready-made laboratory large enough to reflect changes expected for a whole lake, but small enough to allow scientists to sample everything up and down the ecosystem food chain. Also, there was already much information available on the bay--a water body with a rich fishery made possible by the high biological production of its microscopic phytoplankton and zooplankton.

Zebra mussels were found capable of filtering Saginaw Bay's entire water volume in one to four days. While this high filtering rate fuels explosive zebra mussel growth, it also means that other parts of the food chain are deprived of needed energy and nutrients. Prior to the zebra mussel's arrival, much of this energy and nutrients supported microscopic animals (zooplankton) that in turn served as a food base for young (larval) fish. The spread and growth of zebra mussels have decimated this important free-floating part of the food chain, raising concerns that all of the bay's fish stocks may suffer.

Mussels may also release nutrients that encourage algae growth, especially blue-green algae. Certain forms of a blue-green algae named Microcystis are toxic to fish and cause gastro-intestinal distress in humans. Blooms of Microcystis have recently been noted in Saginaw Bay and in western Lake Erie, where studies are underway. With increased water clarity due to the mussel's continued filtering of the bay's water, thick mats of thread-like algae now are abundant near and on some water intakes. These algae have the capability of producing off-flavor compounds that can affect taste and odor of municipal water supplies.

The zebra mussel has transformed the Saginaw Bay ecosystem from one that scientists understood fairly well, to a new system with a large number of unknowns. Additional work will be needed to document and fully understand how this new system behaves.

Although a certain amount of change has and will continue to occur in the structure and function of Great Lakes ecological systems, NOAA and university scientists emphasized that the zebra-mussel-induced changes they have seen in Saginaw Bay's ecology are more extreme because it is shallow and has suitable substrate for the mussels. In the long run, more ecological instability can be expected wherever zebra mussels spread, making the ecosystem more difficult to predict and, therefore, more difficult to manage and protect vital resources.

In addition to the yet-unknown economic impacts on Great Lakes fisheries, costs to reverse or prevent zebra mussel fouling in water plants and other industrial water works alone are estimated to total $5 billion by the year 2000."

I guess to accurately discuss this subject you would need to find out the variables of that ecosystem and how it is similiar/dis-similiar to Texas lakes. I DIDN'T see any mention of the CONTROL synopsis only the conclusions section. Plus issues such as water depth of the bay, the type of substrate preferred by the zebra mussels, how much money is currently spent on cleaning the industrial water supply lakes for other problems that might be cured with the zebra mussels, the changes necessary for TP&W to handle zebra mussel issues.

It is entirely conceivable that the zebra mussels can't establish effective colonies in the majority of our lakes (I don't know and don't imagine anyone else does either). Quite frankly, the information cited above doesn't give me a COMPLETE OR ACCURATE picture of the research sufficient to cause ME any real concern. Indeed, it really seems to just pander to the industrial water supply folks, with an alarmist liberal slant. Sorry, but I remain unconvinced of the threat with the information as provided. Is is a good idea to wash/dry your boat after a tourney in a zebra mussel lake...sure.

It may be that we HAVE to eliminate all the migratory birds to PROTECT our waters from the zebra mussels (not)...More laws are NOT going to do anything to stop this infestation, but it always seems to be a preferred (laughable) method...public awareness is an EXPENSIVE option as well. May be easier to live with the problem than try eliminate it...just saying...take a real hard look at BOTH SIDES OF THE ISSUE...not just one...the answer may be right in front of your nose.

Kind of reminds me of the KILLER BEE issue...not really a threat, easy to deal with, but lauded as a PUBLIC SAFETY HAZARD.

So zebra mussels are major contributors to global warming. There must be a way to control them with some sort of ill contrived phytoplankton consumption tax.

The background information mentioned above was from 2000? What, if anything in the last 13 years has been discovered about these muscular zebras?

How do the saltwater communities deal with oysters, barnacles and other clinging critters?

I HAVE discovered a BENEFIT of the ZEBRA MUSSEL....Catfish bait...apparently catfish love them....so we can get paid to clean the municipal water supply lines, then sell them to Danny or Lew King to make catfish bait...so maybe we take them from problem to profits....just like Waste Management...profiting from trash....Hmmm, maybe I need to explore and/or research this subject some more.

They take shrimp boats and muddy up the water to give them something to do?

Zebra mussels will have a different affect on different body of waters. They will cause a shift in the ecosystem. Some organisms may benefit, others will not.

Baitfish will suffer as the zebra mussels will outcompete them for the phytoplankton, and native fish will have to find new sources of food, which many of them will do, and many of them will resort to feeding on the zebra mussels themselves. Whitefish, and important commercial fish in the Great Lakes, have done this, and although they are still present, the shift in nutrition has affected their average size and hurt the commercial fishery.

Because they prefer shallow water (less than 50 feet), their effect may be different on small lakes vs large lakes, or even shallow lakes vs deep lakes.

As mentioned in this thread, expect them to clean up the water. Largemouth bass fisherman will see an increase in habitat for this species as the clearer water will encourage weed growth in deeper waters. Increased habitat means a better fish population as long as a food source is available. A lack of food source an a lot of fish means a stunted fish population, so bass fisherman could see something good or bad depending on the effect of weed growth and the bait situation.

A bad thing about these guys is they prefer the larger members of the phytoplankton, so they ignore bluegreen algae. This gives these little guys a competitive advantage resulting in an increased chance of blue green algal blooms. Algal blooms are associated with oxygen depletion and fish kills.

Predation on these things will happen but will likely not curve their population growth as it will occur exponentially. The population growth will curve when the food situation becomes poor for the zebra mussels, which also means the food situation will be poor for bait fish.

LIke I said,fish will have to adjust to the new food situation. Food sources at the top of the water column will decrease. Food in the bottom part of the lake will increase (small worms, zebra mussels, etc.)

If pollution is in the soil, count on it concentrating in the tissues of the mussels, and if the mussels become a main food source, it could really affect the safety of the fish flesh for eating. PCB's and other pollutants that may be covered up by sedimentation at present, will come back.

So here is my take. Possible positive affect on the bass population. A disaster for intake pipes, marinas and the boats that are permanently wet stored, a disaster for beaches and swimming areas, a disaster for forage in the upper part of the water column.

The bad things will definitely outweigh the good things in most lakes. Bottom line, we don't want them, but reality is we will probably have to deal with them because it only takes one mistake to spread these little guys, and to get 100% compliance will be pretty impossible.

In a cost/benefit analysis, Lake Erie might be an example where you could say zebra mussels helped because the lake was considered dead in the middle 1970's. The mussels helped bring that lake from a polluted mess to a much nicer body of water today, but if you have a lake that is not "dead", the costs will most likely outweigh the benefits.

Sounds like we have finally got a little knowledge on the subject. From what I read of your post wrestlefish, it seems the TPW will have to learn how to manage the mussels on the lakes they inhabit.

You say they are a disaster on the beaches...I suppose I don't understand that comment.

The mussels helped bring that lake from a polluted mess to a much nicer body of water today, but if you have a lake that is not "dead", the costs will most likely outweigh the benefits.


Let me see if I got this figured out. So zebra mussels will clear the water up, then become an important source of food for other fish, as they out compete the baitfish. At first they will grow exponentially then as they clear/clean the water their growth will slow down and/or decline.

Water clarity to 50 ft may become a reality on the shallower lakes, potentially hurting the fishery but helping the recreational aspects of a lake (boating, snorkeling, diving, skiing, etc.,) Possibly it could increase the recreational diving and snorkeling industry with the increased water clarity. Also, it appears the mussels will require the launching of a new industry in cleaning the municipal water supply pipes, and re-launching of an old "dead" industry such as dry docking and periodic cleaning of wet stored boats.

Fortunately, our Southern waters are not as polluted as many other places with the harmful PCB's, so this issue, for the most part is a non-issue. But apparently they will improve water quality, which could decrease and/or change the amount or type of chemicals that the municipal water supply have to use to treat the water we drink.

Currently, we use triploid grass carp to eat the high concentrations of algae (and dirty up the water) of which Cypress Springs is an example. Seems that these carp can be an effective tool to can handle the remaining blue green (problem, less desirable) algae?

As I recall, what our northern friends call whitefish we call carp, so we now can count on catfish and carp to eat the mussels.

Basically, as I have already stated, we really don't know what impact the zebra mussels will have on our lakes. It does appear there are trade-offs and it does appear we will get an opportunity to deal with it, like it or not. So while common sense and good judgement is seldom involved in any campaign to "Stop Something" that can not be stopped despite our best efforts (ie., via Migratory birds), sensationally beating the drums about these creatures being the demise of western civilization is NOT the answer either. In fact, these mussels will have both positive and negative impacts on our waters, our fishing, our lake use opportunities, and our lake management plans. Of course, the municipal water supply folks won't like it, but they generally don't like anything...that fishermen do.

As for beaches, the mussels will cover the lake floor, and the broken shells are sharp. Large weeds like Hydrilla often infest zebra mussel waters. Bad for swimming and boating.

Don't confuse clear water for good drinking water. Remember, they only eat phytoplankton, and the clearing water will make room for larger weed plants like Hydrilla. Lakes full of hydrilla have "slimy" water, and that will be a cost.

Hydrilla can create some good bass habitat, so bass can be winners sometimes with zebra mussels, especially if the oxygen content and food sources stay viable.

Things that rely on shad as their food base and don't adapt to new food sources will be losers. Bluegill populations should theoretically increase as weed growth increases, so striped bass and white bass will need to adapt. I would think that zebras will affect whites, hybrids, and striped bass more so than say largemouth and smallmouth bass.

Lake Worth is just starting to get some favorable reports on the tissue of fish as the PCB's are getting trapped under sedimentation and thus away from the food chain. This is a good thing. A zebra mussel infestation in this lake would likely bring those nasty chemicals back into the food chain and make those fish dangerous for the table. It has been reported that a zebra mussel can take contaminates in the water and concentrate them by 300,000 times in their tissue, and that is not a typo. Anything that eats them becomes vulnerable. That includes fish and waterfowl that enjoy eating these things.

Bottom line. They are not suppose to be here. Anytime you put something someplace that is not suppose to be there, it is bad, but we will most likely have to deal with it as bad as it is.

Yep, kind of like some of the snakes and fish that now inhabit the everglades...learn to deal with it...because we couldn't prevent it. It may be that we have to get some northern biologists (zebra mussel experts) hired into the TP@W to keep an eye on them...and figure out management plans based on their colonization in our lakes.

I am sure they already know what they need to do. You are not going to control them in the lakes. You just kind of have to let them take their course. You might be able to control them in small manmade areas however by controlling water temperature and such. Those examples are there of what they have done up north to adjust the Zebras, and what they do in Europe when they build knowing they have to deal with the mussels.

Example. In Europe, anytime they build structures with intake pipes, they build two. ONe to use and one to cap off. When they close one off to clean it, they open the other one. I am not sure we have that luxury with our old pre-zebra mussel structures.

It causes a lot of problems, so we need to minimize their spread by draining our boats. It is going to be a big tax expense if we have to accommodate for zebras in all of our bodies of water at once.

Unfortunately, now that they are in Bridgeport and Lewisville, the Trinity River basin is in trouble, and that is a lot of lakes. I wish we could stop the flow of water from one reservoir to another, but that is pretty much impossible.

You would think by now the experts would have figured out a way to control the population, if not eliminate it altogether.

And here lies the problem. They reproduce so fast that once they are established, there is no getting rid of them. They simply take over the bottom of the lake, and they change the ecosystem indefinitely.

From Wikipedia

"The life span of a zebra mussel is four to five years.[11] A female zebra mussel begins to reproduce within 6–7 weeks of settling. (see Borcherding, J. (1991): The annual reproductive cycle of the freshwater mussel Dreissena polymorpha Pallas in lakes. Oecologia 87: 208-218).

An adult female zebra mussel can produce 1,000 eggs each reproductive cycle and upwards of 1 million each year. Free-swimming microscopic larvae, called veligers, will drift in the water for several weeks and then settle onto any hard surface they can find. Zebra mussels also can tolerate a wide range of environmental conditions and adults can even survive out of water for about 7 days."

So understanding that they are here to stay, there will be strategies implemented to keep the mussels from plugging equipment. Within equipment, adjusting water temp, chlorination, and other strategies can be used to keep them from ruining equipment. It just becomes a never-ending battle that nobody wants to deal with, but we will be dealing with it. We kept it out of Texas for a long time. Took over 20 years to get here. But now they are here.

I don't know how they reproduce, but I wonder if sterilization could be an effective strategy? Or if there is something, a fish perhaps, that can feed on the young in the early stages (larvae) of life...

They reproduce to fast for predation to be an answer. They have found some parasites that are promising. I would think that something host specific to a zebra mussel could be the answer.

Like you, I think the answer may be biological, but I think a parasite, bacteria, or virus may have a better chance of having the wide scale effect. Predation just doesn't work due to their pure numbers and ability to reproduce. If something is to be used to wipe them out, it too would need to be prolific, and microbes can do that, whether it be a bacteria or a virus.

I was up on Texoma this weekend and noticed signs warning of Zebra mussel infestations...do you have any idea how long they have been established there and what, if any, impact has resulted over that time horizon?

I think this is the third year with zebra mussels on Texoma. IMO its been a net positive for the lake because they have made the water clear. The first 2 years they came on strong. I would find them all over the shoreline and beaches. Now I rarely see them at all. Catfish and crawfish eat them. I think carp and drum may eat them as well. Hasn't affected the fishing. I don't do anything for the boats either. We have sea ray on a lift and 40ft houseboat that stays in the water and we have not had any problems despite absolutely no prevention measures. Best thing you can do is drive the boats once a week although the houseboat rarely gets driven and still no zebra mussel problems. Initially in the first two years there were a lot of reports of big boats with zebra mussel problems.

Ya'll just need to drain the water out of your boats which you should be doing anyways.

http://en.wikipedia.org/wiki/Zebra_mussel

Crayfish could have a significant impact on the densities of 1 to 5 mm long zebra mussels. An adult crayfish consumes an average of nearly 105 zebra mussels every day, or about 6000 mussels in a season. Predation rates are significantly reduced at cooler water temperatures. It seems that fish do not limit the densities of zebra mussels in European lakes. Smallmouth bass are a predator in the zebra mussels' adopted North American Great Lakes habitat.[14]

So crayfish are the answer...and they even muddy up the water in the process....Interesting information.

IMO all the science out there as it relates to zebra mussels in TX is outdated junk. Catfish eat them, but you won't read a word about it on any article despite numerous youtube video's documenting zebra mussles in the bellies of Texoma catfish. If crawfish, catfish, and small mouth eat them then I don't know why carp and drum wouldn't eat them either.

I don't give any of these supposed scientific experts a ounce of credibility after they cost the local Texoma economy millions with their false green algea scare that never hurt a single person in OK or TX, nor has it resulted in a single death in the entire country ever. Their incompetence was so damaging that it led to the OK legislature removing the corp of engineers authority to issue algea warnings in the state.

Seems the "experts" always seem to have an angle to write from...that is whomever is paying for the study, gets the answer they want...there is NEVER any truly independent evaluations or "Unbiased Studies" performed...that is why I always have a skeptical perspective when I hear someone sounding off about some "Problem" that needs our tax dollars or our private dollars or our assistance to solve.

I am from New York, and grew up fishing lake Erie; i have seen how the zebra muscles affected the water and fishery, i can tell you that it takes longer than 3 years to see the negative impacts of these prolific breeders.

nothing affects the habitat of fish like crystal clear water, do some research on it. i remember seeing the fish swimming around 35-40' down at times on Lake Erie. This clarity definitely changes fish behavior and ability to cope with the sun and its affects on them and their habitat.

zebra muscles are not an asset, rather they are a destructive, non-native species to our ecosystem that should have never been released into our waterways by foreign ships so long ago. they disrupt the food chain and as the smaller fish get hit in population size, eventually the game fish we all love to catch will see a decline as well.

hopefully our native Texas species fight back and show these foreigners who the boss of Texas is!

I used to fish the St Lawrance and Lake Ontario growing up in the summers with my grandpa. I hear the St. lawrance is now clear.

When they invaded Lake Erie did they come on strong for the first two years and then subside to the point that you rarely see them anymore on the shoreline?

it would be nice to see TPWD enforcing this rule with a bit more aggression. placing GW's at boat launches to inspect boats and gear would be a high cost, but might help keep our waters free of zebra muscles.

what do you guys think should be done to help keep the spread from happening?

Dumping a couple thousand crawfish at every boat ramp is probably the best solution

I don't think eliminating the 5th amendment for boaters is a very good idea. Law enforcement can not stop the invasion. They can't even stop illegal aliens from invading TX, come on now....

Here is the deal

There is a lot of people out there that like to be positive thinkers and just can't get past the fact the zebra mussels are destructive. They don't belong in Texoma. They don't belong in Lewisville. Where Zebra mussels live at present, predation does not keep them in check. Predation will not keep them in check here either. We don't want them in our lakes. We need to drain our boats so it doesn't spread. We will have to deal with the negative impacts of the mussels in our contaminated waters.

The bodies of water that are underneath contaminated bodies of water are probably screwed.

If you don't believe the experts, ask the people that live with them. They will tell you the negatives outweigh the positives. Better bass fishing isn't worth the damage these things do.

They did clean up Lake Erie initially. That was a good thing. But now Erie has to deal with the afterfact. And that is a bad thing.

We will be dealing with a bad thing eventually. It may take a while.

As for Texoma, I think the drought has helped us there a bit. Fluctating water table is a good thing to take out mass quantities of Zebras on the shore. They will rebound though. That is what they do. They are the king of reproduction, and they will harm our fisheries. YOu can pretty much count on it.

I have been on Lewisville easily 30 times since the alarm sounded about the Zebra mussels in Lewisville. I have religiously drained my boat and seen others drive away with their bilges full. They came out and painted large signs on the ramps to drain the water, and I thought they were going to step up on the enforcement. But to this day I have never had my boat checked or seen anyone else's boat get checked.

I call BS!

They already know that this is a waste of time and are simply doing PR to say they have done all they could. I think that we are going to break even on the balance sheet and the lakes will change but they usually do from year to year.

I live @ lewisville pretty much all summer as a watersportist
and cat fisherman by night, and chase fish during spring, whether its my pleasure boat or fishing boat.If people are coming to visit the lake they no nothing about pulling their plug drying their boat etc...If you really think about it we just need to slow down at the ramps with out getting in a fistfight LOL....
(us) who use the lake all year will suffer....Not to point fingers but pounding some cold ones and trying to get off the lake,leaving your ballasts full of water in your wakeboard boat then heading out to another lake is a major transfer!!!!!!!!!!!!

There is no way to stop the spread of them.You can slow them down, but over time zebra mussles will be in most if not all Texas lakes. There in almost all lakes in Wisconsin where I'm from. Zebra mussles will effect the fishing here as they have everywhere else they have invaded. That is a fact.

Exactly. You can't stop the birds...too many boats etc.
Think about it, all it really takes is one disgruntled creep and a bucket.
And we are almost finished building the hugely expensive multimillion dollar pipeline from Texoma to the North Texas Municipal Water District treatment plant here in Wylie, built I believe, to prevent the spread into Lavon. I hope it was for more of a reason than that. Cause it's probably already there.

the spread of zebra muscles as with everything else that is invasive is due to humans and our endless quest to mess up what god gave us ....
its such a shame to see the endless trashing of our environment to satisfy whatever "utopian" environment we seek ....
with all the water transfer possibilities and the need and want to do so , I doubt there is any turning back the clock on these things ....

Why not just make it illegal to harvest Zebra Mussels with a cast net?
There, problem solved.
Well, at the very least...Rowlett Creek should remain Zebra free for years to come. sarcastic

There ought to be use for these things. Maybe they could be harvested somehow, mixed with asphalt, and use them to pave the roads. Some of the roads around Lake Fork (Hwy 17) already sound like they have done this - noisy is not the word.

Best thing you can do is drive the boats once a week although the houseboat rarely gets driven and still no zebra mussel problems. Initially in the first two years there were a lot of reports of big boats with zebra mussel problems.

Ya'll just need to drain the water out of your boats which you should be doing anyways.


I am from New York, and grew up fishing lake Erie; i have seen how the zebra muscles affected the water and fishery, i can tell you that it takes longer than 3 years to see the negative impacts of these prolific breeders.

nothing affects the habitat of fish like crystal clear water, do some research on it. i remember seeing the fish swimming around 35-40' down at times on Lake Erie. This clarity definitely changes fish behavior and ability to cope with the sun and its affects on them and their habitat.

zebra muscles are not an asset, rather they are a destructive, non-native species to our ecosystem that should have never been released into our waterways by foreign ships so long ago. they disrupt the food chain and as the smaller fish get hit in population size, eventually the game fish we all love to catch will see a decline as well.

hopefully our native Texas species fight back and show these foreigners who the boss of Texas is!


I have caught tons of fish in the crystal clear waters in Canada...just saying....

I missed the part where scientists say birds are transporters. There's evidence of that?
Anybody heard of Zequanox?

The evidence for birds spreading them is kinda sketchy. Problem is there have been very few studies done regarding this. The only info I've read so far that sounds legit is from a study made back in the 90's. http://www.significantudders.com/quagga/Johnsonpaper.pdf
It found that birds can transport the zebra mussels, but it concluded that they would be in small enough concentrations that they would probably not be viable for reproduction. Based on this there are many government entities that claim "Birds Do Not Spread Zebra Mussels." Well I think that is a ridiculous assumption to make based on the sheer number of birds traveling from one spot to the other. I would venture to say that cormorant populations in most areas were much lower when the one study was made.
And hey! Thanks for bringing up Zequanox. I never heard of it, but google took care of that. It sounds pretty encouraging. Nice to read some good news about this fiasco every now and then!

As a former Great Lakes fisherman, heed the advice and this will slow down the Zebras spread but nothing can completely stop them. The long term results will be gin clear lakes and a breakdown of the food chain.

We Do take it seriously Wild Bill, it just peeves some of us that they completely overlook many of the causes for the spread and simply focus on "limiting our rights/freedoms" and "use this issue as an excuse to hit our pocket books some more" due to some big money lobbying efforts and limited (poor) scientific research...

I dont guess I understand why everyone is getting so worked up over zebra mussels. It appears to me they have actually benefited the great lakes. The water is cleaner now than it has been in the last 100 years. The fish seem to be thriving. I would say the smallmouth fishery is outstanding right now. It does not seem to have broken down the food chain yet and I really do not see that happening. I think the biologist are getting worked up about the Zebras like they do the hydrilla which in my opinion is the best thing going for a lot of our Texas lakes if the TP&WD would simply leave it alone.

You might be right gw12.....of course you might be wrong. I'll admit that I don't have a strong inkling one way or the other as to how this will all play out. I will say that so far the effect they have had on Texoma after what 4 or 5 years is negligible. At least my observations point that way. I'm thinking fluctuating lake levels and hot summer temperatures will keep them at bay down here. Sure hope so. Cause draining boats and minner buckets will just be a speed bump to their spread. Let's hope that things like Zequanox which Texasflycaster mentions above will help.He talks about it on his website which is a pretty durn good site by the way. thumb

Know matter what you all do to try and prevent them from infesting TX lakes isn't gonna work. Just like feral hogs. If you ain't got them now you will. Why waste the money to try and combat them instead of research as to how to control them? I clean my boat and will do what I can, but I am only one fisherman.

Zebra mussels are invasive species. They got here because mankind has learned how to navigate the world. We have and still do put stuff where it is not suppose to be, sometimes by design, and sometimes by accident. Zebra mussels are not here because of birds, they are here because of us, and they are here to stay. We may be able to slow down the infestations, but as long as people move from here to there, there is no stopping their spread. When we make the conscious choice to not drain or boats and follow the guidlines established, the movement is not by accident, it is by humans being careless, and the pattern of humans being careless with the environment has been well documented since the day we first set foot on this great land. As a population, to think that 100% of people will do as they are suppose to is not realistic. There will always be those that think it is not their problem as it easier to ignore the mandates than take them for what they are. The government should do more right? They haven't done anything about it, right? All they do is tell us what we can do and can't do, right? We don't need a big brother right?

All you have to do is read this thread and you can see that we do need a big brother. These things are bad, but there will always be those that will choose to ignore reality and celebrate the clear water! People, as a population, have always been and always will be ignorant when it comes to our environment. Humans have abused our world to the point that many scientists have pointed out that the world is in the midst of another mass extinction, and the fault lies soley on mankind's shoulders. And like the spread of zebra mussels is hard and maybe impossible to stop, part of the reason for that is because the attitude of our population towards the only world we have will also likely not change. Don't forget about your grandkids. It is our responsibility to take care of this earth for them, but that is the problem. Taking care of our earth often clashes with the economic climate. And the economic climate is also very important. People have and always will sacrifice our environment for the mighty dollar; it is a really tough balance as they often are pitted against each other. The price of human progress has been high when it has come to our environment. Unfortunate, but true.

I get so tired of our people complaining because we are trying to do something about zebra mussels, and complaining about trying to do something about hydrilla. When those conversations happen, it is so evident that all we care about is catching a fish without regard to flood control, drinking water, etc. Believe it or not, we have a lot of people that live in Texas, and for us to thrive requires more than just pulling a bass from a hydrilla mat. There is more going on here than most people realize as most of us have blinders on.

I had a lot to say, but a lot of smart guys on here have already said it much better than I could have. I would like to say that to blame boaters, and fishermen for this is ridiculous. I always drain my boat and motor at the ramp anyway. To have some clown there, charging me twenty dollars to steam clean my boat when it won't even help is nuts.

The problem is that boats spread them. Waterways that are connected are most likely screwed, but the unconnected waters can still be protected. Texas has a lot of reservoirs, but many places have a lot of isolated lakes, and those waters would be vulnerable to trailered boats. so, the measures can make a difference, but in Texas, probably not as much. MOst of our waters are connected here. Once one body of water gets them, the sister bodies will most likely be infected as well. So the question is, how much do you do to prevent the spread. Do you just throw your hands up, say uncle, and just spread it carelessly, or do you take REASONABLE measures to help stop or most likely slow the spread. Slowing it is good right now. Looks like there is some biological products that have been tested are are ready to be launched to battle the mussels. IF we can hold them off for just a little while longer while we wait to see if there is any unintended affects from Zequanox, it could help. Hopefully this microbe is the answer. It looks pretty promising.

Yup. I think that's right, they're here to stay. I am pretty sure that we had a closure of Texoma due to a Blue Tide event after zebra mussels got established (a downside like the bloom events on other zeeb lakes). So that may be a downside. If you take a look at Ray Roberts right now, tell me I'm wrong, but the clarity has changed dramatically.
Being here to stay is one problem, containment and slowing the spread is another. I may have already said this, but just wait until they hit around Austin, and the Guadalupe river area. Page 1 all day long - tourism economy destroyed. Surprise, surprise surprise.

That is about the only negative to the zebra mussel...but that is why the "BIG MONEY" hires Lobbyists (and Biologists) to Persuade the Politicians to enact laws because they don't want to pay a person(s) to clean the pump entrances occasionally.

There is no substantial evidence taking REASONABLE measures to help stop (or slow) the spread works...Supposedly, they have been trying to stop (or slow) them for 40 years...still hasn't worked....and we apparently don't have a scientist or biologist with enough ABILITY to come up with a product to kill them (assuming we really want to)...Really? I mean, we have mostly cured cancer, aids, and a host of other calamities....so my question is...how HARD ARE WE REALLY TRYING??? Answer, we are NOT trying to stop it...I would suggest that if we were trying to kill or control them, we already would have...and NOT BY ENACTING LAWS, which also FURTHER LIMITS our FREEDOM.

I am just saying you (and everyone else) need to look beyond the propaganda on this subject and you will begin to see the true devil that is at work on this subject.

Just a couple of points...and I'm really not meaning to get into a pizzin' contest with anybody here nor do I wish to disrespect anybody on this forum or their opinions. But these thoughts come to mind.
Believe it or not, mankind is just as much a part of the environment as any other creature on the planet. We affect it - it affects us. As much damage as we are capable of doing to the environment, we are the only organism conscious enough to give a rats arse about it. And because of this the levels of pollution in THIS country are MUCH lower than they were 30 - 40 years ago. When I was a young man it was common to see billowing plumes of smoke coming out tailpipes of cars and trucks. Mosquito sprayer trucks rolled every summer night, spraying DDT. Termite exterminators sprayed under houses with Chlordane, a nasty insecticide that remained active in the soil for 15 - 20 years and longer. Smog was prevalent in most major cities. Sewage treatment was not near as efficient and malfunctions at plants resulting in major sewage spills were common. The steel mills and factories and lumber mills and chemical plants spewed toxic waste into rivers to an extent that a few rivers actually caught on fire. So we started enacting rules against this kind of gross negligence and in response the private sector of this country came up with ways to curb the pollution. Guess what? We've done a pretty good job. But in the midst of this our benevolent keeper, "Big Brother" created the EPA and turned them loose on Americas industrial backbone. Through hard handed regulation they shut down most of the major steel mills and similar industries back in the mid 1970's. Well what do you think happened to all of the tooling and equipment in these plants? They didn't just scrap it. Nossir, they sold it to companies in India and Southeast Asia and to the communist thugs in China, or in some cases they just moved their operations overseas and continued manufacturing. Of course all of the smaller companies that supported these industries here in America suffered and many if not most of them went out of business, The "Rust Belt" was born. And while this was going on The Chinese and the Indians and the South Koreans etc. were learning how to use all this equipment they bought at the fire sale. They sucked at it at first, but I venture to say they've gotten pretty good at it now. So our "Big Brother" that is so good to us went out of it's way to see to it they could then flood our shores with their cheap products, made without regard to the well being of human life or any concern for the environment at all. I mean how do we compete with conscripted labor, actual slave labor, prison workers and non-regulation of pollutants? So now we have gone from being the worlds economic powerhouse, The top dog of research, development and manufacturing to a service economy. Sad fact is, if you ever read anything at all on how to grow a healthy economy, you MUST CREATE WEALTH! This can't be stressed enough. Without it's creation you are merely shifting old funds around while they dwindle out to the foreign countries who supply you with your goods. The bulk of the remaining money is shifted around back and forth between Big Brother, government employees, entitlement junkies and bankers and lawyers. The only way you create wealth is by taking a raw material from our planet and turning it into something you can sell to other countries. We don't do that any more. The results of this are baring their fruits as of late, with high unemployment and multi-trillion dollar deposits. So Big Brothers response to the economic nightmare we are all facing is to TIGHTEN DOWN ON EPA REGULATION EVEN MORE! While it fools the fools into believing all is well by allowing the Fed to prime the pump by printing trillions of dollars of money to sell to itself. All the while this goes on the feds...the FBI and the CIA and the NSA and the state and local law enforcement agencies invest billions on military equipment cameras, drones, handheld flirs, Echelon,cell phone stingers, data mining, ammunition etc...etc...all of which is intended for domestic use.

I love the outdoors, and nature. my fishing buddies will testify that I often will spend as much or more time picking up garbage as I do fishing when I go out. I always carry my grabber with me when I fish just for that reason, I support reasonable environmental regulation, but with the knowledge that the private sector if allowed to compete in the market place will find solutions to problems through scientific research and development. Big Brother won't. Big Brother is out of control. Big Brother just spent 350 million of our ....yours, mine and our offsprings dollars on a pipeline so Lake Lavon wouldn't become infected with Zebra Mussels. Boy that worked real good didn't it. Now you can conclude that those of us who question this ever increasing sea of regulation and taxation are a bunch of clods who don't care about what impact the Zebra mussels and other invasives have on our lakes, or that we all think they will be just great because they'll clear the water, but you would be wrong. Just imagine how important this will all be when we are scrounging for food, trying to protect our families from roving bands of thieves as well as our Chinese overlords after our economy completely tanks.It will be the furthest thing from most peoples minds. I'm not a prepper or a John Birch wing-nut, but it's clear to me that this is the direction Big Brother is taking us.

To quote Bob Dylan... " It's a hard rain gonna fall."

Most of you people live in a dream world.
The reason there is an issue with the Zebra Mussels is economic only, due to
water supply pipes being clogged with the mussels.

All you hippies out there need to recruit the same group of English scientists who
falsified the global warming data a few years ago. I am sure they could come up with some
interesting results for you hippies.

When it comes to Zebra Mussels the thing to remember is as has been commented before the issue relates to water supply pipes.

The other thing to take into consideration is that all the lakes in the state are designed for water retention and distribution first. All the recreational activities that take place boating, fishing, and swimming are just that recreational and in importance of order are second.

The recreational activities that take place are just a side effect of supplying the masses water.

Somebody made a comment about "cleaning the pipes", it isn't a subject of cleaning the pipes it is replacing the pipes

Hey, regardless off where folks fall on this issue, it's good to see some feedback from a warden. Glad to have you here and I think your input will be very useful and appreciated.

I am quite confident in my credentials to comment on this subject matter. However, when you read crapicats posts, it is quite evident he doesn't even stand on a platform when it comes to this subject matter. I don't always agree with Duckcreek Dave on this issue, but I appreciate where he is coming from. And I completely understand how environmental legislation often trumps economic progress. Too much of a good thing is often a bad thing. But the government has been responsible for the environmental cleanup of this nation, and the 1972 Environmental Protection Act was overall a good piece of legislation. Does it hault progress sometimes, yes. Is it unreasonable sometimes, yes. But most of the time, it has been a saving grace for our air, water, and natural resources. Our own national bird, the bald eagle, has the EPA to thank for it's existance today. The EPA has it's work cut out for it in the future with big problems that have huge implications to our way of life. Ozone depletion, global warming, air and water quality, sustaining green places for us to enjoy, and of course the invasive species. (And yes, I am of the opinion that global warming is a real thing that is being accelerated by the progress of man. Just to say that since I know some on here want to ignore that research as well). And although it often creates some red tape that is difficult to navigate around, removing the EPA would be disasterous.

The EPA has done a reasonably good job with air quality, water quality, and the protection of our natural resources. The zebra mussel and other invasive species is another battle that has been happening for about a century and seems to be coming to head now especially in the great lakes regions and with zebra mussels throughout the country.

I am from a platform that wants environmental protection. Duckcreek Dave also wants environmental protection but he also wants some fiscal responsibility. I am actually there also, but I am okay with spending more money than Duckcreek dave. Doing things to protect the infrastructure of our watersheds is also a platform. Crapicat should try to find a platform different than celebrating the gin clear water, because out of all the angles you can take on the issue, that is the one that makes you look stupid. He sounds like he wants to lead a campaign to plant zebra mussels in every body of water in Texas so we can enjoy the great fishing and improved drinking water. The only thing gin clear here is a complete disregard for scientific research, environmental responsibility, and the love for the outdoors. It is very sad when fisherman make posts with such apathy for the environment they enjoy. -- Touche

I think it was Forest Gump that said, "Stupid is as stupid does" The EPA has looked stupid at times, but so has industry with out those checks and balances.



Texas is actually in a pretty good situation when it comes to the mussels. It is early enough in the infestation where if we can buy a little time, we can wait and see if the microbe solution works. If it does, we are in the clear, and if it bombs and does unforseen damage, we didn't go there.

I think you are right wrestlefish, we do have the same goals in mind, and I would venture that crapicat shares those goals. I think he is just fed up and frustrated with the workings of government and the waste of money thrown at so many many things that do nothing to benefit either the taxpayer or the environment we live in. I mean with the revelations about the NSA spying on us, the IRS scandal, the attempted takeover of 6% of the nations economy through Obamacare (as a health care worker myself this one hits close to home) etc. It's not hard to become jaded to the governments shennanigans. It's not that I'm opposed to funding research on zebra mussels. I'm all for it. But I say that with the tempered knowledge of the reality facing our country.

As of April 1, 2014, the official debt of the United States government is $17.6 trillion ($17,578,141,920,036).[1] This amounts to:

$55,372 for every person living in the U.S.

$143,543 for every household in the U.S.

• 103% of the U.S. gross domestic product.

• 559% of annual federal revenues.

* Publicly traded companies are legally required to account for "explicit" and "implicit" future obligations such as employee pensions and retirement benefits. The federal budget, which is the "federal government's primary financial planning and control tool," is not bound by this rule.

* At the close of the federal government's 2013 fiscal year (September 30, 2013), the federal government had roughly:

• $7.8 trillion ($7,849,000,000,000) in liabilities that are not accounted for in the national debt, such as federal employee retirement benefits, accounts payable, and environmental/disposal liabilities.

• $23.8 trillion ($23,768,000,000,000) in obligations for current Social Security participants above and beyond projected revenues from their payroll and benefit taxes, certain transfers from the general fund of the U.S. Treasury, and assets of the Social Security trust fund.

• $27.3 trillion ($27,300,000,000,000) in obligations for current Medicare participants above and beyond projected revenues from their payroll taxes, benefit taxes, premium payments, and assets of the Medicare trust fund.
source: http://www.justfacts.com/nationaldebt.asp

Now look at the first number where it says "$55,372 for every person living in the U.S." Keeping in mind that now roughly only 50% of us pay any federal tax at all, that doubles the amount a working person will be asked to pay to a total of - $110,744, not including all of the additional debt burden listed above. This number is unfortunately not static, it grows daily.

So the plain wretched truth is,and I hate that this is true, we don't have any money to spend.

Very good read. Wish they could "fast track" zequanox. Lake Ray Roberts looks to me like it is clearing quickly. Every shoreline that has rocks has zeebs on it.

“The lessons learned from the zebra mussel infestation in the Great Lakes tells us that over the next few decades the zebra mussels will deplete the nutrients in Belton Lake which will ultimately cause a decline in the abundance of fish and native freshwater mussels,” Sanders said. - http://www.forthoodsentinel.com/story.php?id=13234

details on test trial in Lake Minnetonka. Summary - they have made samplers that zebra mussels and aquatic insects will inhabit. Once a community has been established, they seal the sampler off and experiment on application procedures to kill the mussels. They also will do a safety study. Apparently they want to see if non-target species are affected both in survival and in reproduction. They want to make sure the treatment doesn't effect spawning.

so, it seems like they are moving forward but very cautious. I am glad they are not just diving into deep water without first checking for debris under the water.

Also, they say that treatment is going to require a couple of hours of treatment. It will be interesting to see the application procedures that would be used to treat an entire lake, or if this is just to be used in targeted areas such as beaches and water intake areas. Based on what I am hearing, it seems like it could be a good product, but using it in a lake instead of a small laboratory setting is very different and could pose problems in treatment strategies. It doesn't sound like you can just use an airplane to spread pellets over a lake. It sounds like treatment may be a difficult process.

So it seems like they may have found something. Now they have to figure out how to get the product to the mussels for a duration of a couple of hours which could be a daunting task when you are talking about an entire lake. But before that, an efficacy study and a safety study, to find the effectiveness in a lake setting and potential harm to non-target species in both survival and reproduction.

I agree ,I don't think there is a remedy all we can do is slow the spread with the new rules.. What about the wet carpet runners on the boat trailers after launching or loading ,how we gonna keep them from spreading by hitching a ride in the wet carpet after launching or loading..

It has to air dry. Makes that tougher for people that get into the water a lot. You can only do what you can do.

This looks to have some promise. It won't eradicate the zebra mussels, but if a product can be manufactured that uses this premise, you could coat certain surfaces with a special paint that would prevent the mussels from attaching. Could be a great solution for water pipes, the outside of boats, docks, bouys, etc. UNT is heading the project.

http://www.minnehahacreek.org/project/usgs-zebra-mussel-zequanox-study

Earlier I posted a reseach study that was underway with Zequanox. The original study (https://www.youtube.com/watch?v=oApwoMXo2dI) was going to happen in 2012. Apparently the test towers have been placed in Lake Minnetonka in August of this year and now they will be looking at treatment strategies and efficacy studies. They want to make sure two things occur.

1) In order to kill zebras and quaggas with zequanox, the samples have to be treated for several minutes, something that is easy to do in the confines of a beaker, but much different in anctual lake where volume, depth, and current can all come into play. They will obviously be dealing with the problem of dilution in the large bodies of water.

2) They will be making sure the insect populations on the samplers are not effected. They have also been doing studies on fish populations in test ponds to see if it causes survival issues with fish both in the parent generation and subsequent generations (spawning)

I am pretty sure these test towers are sealed so the zequanox can not leach into Lake Minnetonka. That is good in case there unforseen problems with the treatment, but this does create a problem with treatment strategies. In essence, this just makes a larger beaker where the treatment can not escape. When that barrier is removed, the injections will be subjected to other variables such as current and wave action.

It will be interesting to see if methods can be devised to treat an entire lake, or if it will be more suited to particular areas such as intake valves, beaches, etc.

As far as I can find, the effectiveness of Zequanox in a real lake setting has not been documented. Those results should be forthcoming pretty quick. If anybody else has found a lake that has been successfully treated with positive results, please post.

As far as I can tell, here is where we are with Zequanox

1) It works
2) We have to figure out how to expose the mussels to the treatment for several minutes in a real lake setting. This could be the difficult part.

"Minnesota Department of Natural Resources and the Minnehaha Creek Watershed District's (MCWD) Aquatic Invasive Species (AIS) Program requested Zequanox treatment from MBI after discovering zebra mussels near the public boat launch. The non-chemical product approved for use in open water was applied to a 50 by 60 foot containment area with an average depth of 2.5 feet. Before treating, there were approximately 5,000 live mussels in the enclosure. The treatment began on September 8 and eleven days later results showed 100 percent mortality of the zebra mussels in the treatment area."


This is very promising. Efficacy studies have also been promising. Since the bacteria is dead, there is no risk of the bacterium spreading and as advertised, toxic to zebras. I am still interested to see if it is possible to treat an entire lake - (both physically possible and financially possible). 3000 sq feet of 2.5 feet water is a pretty small treatment area, but still very promising.

And for those that have been defensive about fisherman spreading the mussel, notice the treatment area was a boat ramp. Obviously it must have been birds that are responsible for the transplant smile

The sky is falling! The sky is falling!

The funny thing is we will never get an apology, nor will the people who have to pay fines get their money back, when it is proven that these silly laws don't work and the fishing isn't affected. Some pipes and buoys will have to be replaced early and the water will be slightly clearer. That will be it.

From the US Government's summary:

"Conclusive negative impacts on natural populations of fish, however, have yet to observed (see Raikow 2004)."

The sky actually is falling.

Zebra mussels are not going to kill all fish, but they will cause a shift. Some species will win and others will lose. What they will do is clean the water up. That means your pelagic fish like sandies, stripers, and shad are going to have to adapt as their food source will move to the bottom of the lake. Aquatic worms, crustaceans, and other bottom dwellers will find new habitat. Weeds will be able to inhabit deeper water as the light will penetrate further. Catfish and bass should be fine and they may even benefit. But as their populations go up, other poplulations will go down. So it may be a doomsday for some species and a jackpot for others. If there are any pollutants in the lake, they will become highly concentrated in the filter feeding zebra mussels, and any fish that resorts to eating zebras will also see those pollutants in their tissues. A lot of those PCB's that are buried by sediment will be returned to the food chain. Bad news.

But, you will always be able to catch fish. But it isn't just about fishing. It is about being able to walk on a beach without cutting your feet on broken shells. It is about being able to keep the pipes clean that we count on for our water supply. It is about keeping the darn things off of our boats and motors. Etc, etc, etc.

Ask somebody that lives in the Great Lakes if they are the best thing since sliced bread or something they would love to get rid of. You will find the ladder.

From the EPA

"Zebra mussels continue to profoundly affect the Great Lakes ecosystem. This prolific mollusk filters microscopic algae from the water column, diverting nutrients from open water to lake bottom systems, thus favoring bottom-feeding fish (and their predators) over those such as alewife and smelt (and their predators) which feed in the open water. Aquatic rooted plants (macrophytes) and their communities (e.g. large mouth bass) thrive in water cleared by zebra mussel, while habitat is reduced for species adapted for turbid waters (e.g. walleye). Zebra mussels, accidentally transported by recreational boaters, are now turning up in inland waters in all eight Great Lakes States. Municipalities and larger industries in the Great Lakes each pay, on average, $360,000 per year to control zebra mussels, with documented cumulative basinwide costs of $120 million from 1989 to 1994"

Not good. If we can slow the spread it could save the economy millions of dollars. Drain your boats, but they will eventually inhabit the connected waters as Texas unfortunately is a bunch of connected water ways, and water and the zebra mussel youngsters both will travel south, and there isn't anything we can do about it. But, boats spread them much faster. That is why boat ramps are always areas that have high concentrations in the northern lakes. That isn't a coincidence.

"Every soldier must know, before he goes into battle, how the little battle he is to fight fits into the larger picture, and how the success of his fighting will influence the battle as a whole."
Bernard Law Montgomery

Blaming the birds is just a smoke bomb. The mussels like other invasives are here because of man, and they will continue to spread because of man. We are the cause, and to think we are the solution is a far reach, because one bad soldier can do a lot of damage in this fight that is not going anywhere. Draining your boat is no different than picking up a piece of litter. We do it because we love our outdoors. We are in this together.

When ever you are trying to stop or slow an infection, you identify the vectors and you do your best to hunt them down in an effort to slow the spread. There is no denying that human-kind is a vector in the spread of zebra mussels. It would be completely ignorant to ignore that knowledge and not at least try to do something about it. I am a fisherman. I have no problem draining my boat, and I have no problem picking up a piece of litter that somebody left behind.

Fighting zebra mussels is no different than fighting an epidemic. You find the vectors (source of transmission) and you start there . With diseases, you have education, vaccination, treatment and quarantine. Hopefully education works because quarantine sucks. We have some treatments that are emerging. No true vaccinations yet.

We all know that boats are the major vector in the transmission of these mussels. It is not the only way they spread, but it is the fastest way they spread. To ignore that would be ignorance. My guess is there would be a lot of complaints from people that love the outdoors if there was zero effort to stop the spread by boats. It is so ironic that when there is an effort, people still complain. It is with everything. Making everybody happy is impossible even in the presence of common sense. That is why sometimes you have to do what is right instead of what is popular.

Asking people to drain their boats is the right thing to do. Everybody knows it, even those that don't like it. Unfortunately, please and thank you doesn't always work in the world today, so you get legislation. Some times the only way to get everybody to cooperate is to make a law. That is why we have laws. If everybody would cooperate we wouldn't need laws. And of course laws don't always work, so we need consequences. The domino effect. Utopia isn't reality unfortunately.

Just a picture of some zebra mussels removed from a water intake pipe. They are somewhat of a problem for municipalities and water suppliers.

Good filtration for the water though.

Look at the bright side, water will be clearer, But once you got the zebra mussels, there is not getting rid of them. Mylili farm pond has them and never a boat been launched on it, but plently of birds and Isuspect the Heron that visits daily is the bringer of the mussels.

Why wouldn't someone drain their boat after every use anyway? What good is going to come by leaving bilge water in the boat or leaving your live well full of water that is going to turn putrid and stink up your boat?

In the olden days I used to fish party boats out of Presque Isle on Lake Erie. The prize fish was the blue pike. Then the fishing got worse and worse and the conventional wisdom I heard was that the problem was too many Alewives in the lake. Word was that the Alewives had proliferated to tha point that there was no food left for the pike.
Well, wonder of wonders, someone came up with the idea that Salmon could live in fresh water and they love to eat Alwives! Problem solved. Too bad for the blue pike as I appears they remain extinct but there is a thriving Salmon and Walleye fishery in Lake Erie.
Maybe we can find something that likes to eat Zebra mussels? Could it be tbat they could be a food source also?

Your bottom dwellers are going to eat them. Catfish eat mussels, so they will eat zebra mussels. Crayfish are going to eat them as well. The problem is that predators can not keep these things in check. They are too prolific.

In the Great Lakes, Whitefish have taken a liking to the zebra mussels. It is now part of their daily intake, and the average size of whitefish has decreased at the same time the zebra mussels population has accelerated out of control. It has affected the commercial fishery in a negative way.

Also, these guys are filter feeders meaning they have the ability to highly concentrate any chemical in the water within their tissue. Any pollution in the water can be biomagnified by these little guys, and if they become part of the food chain, this is not good for catfish nuggets.

We have some lakes in Texas with PCB's that have benefited from sedimentation. Some of those chemicals are out of harms way so to speak, but a zebra mussel infestation could bring something like this back in a really bad way.

Unfortunately, I don't see a lot of positives with the introduction to these things in our waterways. While I agree that our waters are all endanger of infestation, I do believe there is a benefit to slowing the spread. I will do my part. I will drain my boat.

With all this high water and dams releasing hundreds of thousands of gallons of water I suspect more of these critters are being transported downstream due to mother nature than due to careless boaters. This is not to say ignore anything you can do to help prevent the spread of the zebra mussels, but if a few gallons of bilge water or water drained from a live well can spread them, certainly massive releases of water at the dam will be pushing them downstream as well.

WHERE ARE ZEBRA MUSSELS?

Zebra mussels are currently in the following lakes: Texoma, Ray Roberts, Lewisville, Bridgeport, Lavon, Waco and Belton. They have also been found on isolated occasions in the Red River below Texoma, the Elm Fork of the Trinity River below Ray Roberts, and Sister Grove Creek, and a boat with zebra mussels attached was found in Ray Hubbard.

Even before this flood, the waterways below infected resevoirs were already compromised. Anything below an infected waterway is endanger, flood or not.

I am not saying they are Great, but I have fished Texoma for many years and before this last Flood, the lake was very very clear, just after a few years of Zebra's. Now, there was a year (3 years ago) where every rock you turned over had them on it, and if you Noodled, you were bound to get cuts, but then the Lake dropped, and they were gone from many of the shores and holes. I have seen some devastating from them around some boats, etc... but I personally fell, that nature has a Way and a Means for all of this... Do I wash my boat out, well it never really leaves Texoma, and I use a Jon boat elsewhere.. but agree that a good washing is good for everything, but they will get to where nature, wants them to go... Birds alone, can put fish in a Bare pond, so I am not sure of a real cure. But they will make a lake cleaner, and I am sure something will find an appetite for them..

Zebra mussels are a blessing and a curse. They are food for a few species of fish, most notable SMB and Pumpkin Seeds as wella a few diving ducks and crawfish will eat small ones and the larvae. Zebra mussels will clear the water but do so by depleting the micro organisms that most fish fry need to survive.

The clear water is a challenge to fish but we can all learn new techniques. Clear water does not mean clean water and pollution is still there.

There are 5 small ponds within 1/2 mile of my house, and all have zebra mussels. Yes water is clear except they do not eat duckweed. None of these ponds have ever had a boat near them so I think the birds and the Great Herons that are frequent visitors are mostly responsible.

Mechanical removal is viable just not practical. Best way is to not introduce them. Which IMO is not always possible. They may slow down once the food is removed but then, the lake will be dead. I often wonder what impact lowering our lakes for winter pools an extra 8-10 would have. A lot of my local lakes are lowered ~8-10 feet for winter and the rocky banks are completely covered with mussels. The die but are replenished the following year. Maybe we just dont kill enough.

Our Native mussels are gone, zebra mussels cover them just like any other rock.

Do your part to prevention but cure needs our support as well. A lot of research mostly in and around the great lakes is being done. I am not a fan of donating money just to donate. I had offered my time and services to several research groups and usually was told we take donations. I finally found one that said, if you wanna help be here Saturday, we are going collecting. Waders and a life preserver are mandatory.

They had dozens of test plots all over the lake and I was witha group that collected every rock and stick in a 20x20 area in 2-3 FOW. Loaded onto a skiff and taken back to the lab where every mussels was picked off, counted and the mass weighed. turns out, that was the control plot, no treatment... just whatever nature provides. After cleaning, we got to return the rocks (4 rock piles) the director laughed and said next year, the piles will be gone and rocks will be all over the bottom.

I learned a lot but mostly just make a donation now, my back did not enjoy picking up all those rocks. There are areas in the body of water that never have a mussel and others where reproduction is unfathomable. Those questions are the ones for which the answers need to be found. The historical data is interesting and from what I saw, annual conditions do not have a big effect. The control plots allways seem to be same density and they have 20+ years of data. Several treatment methods are very effective but result in depletion of game fish and native invertibrates. Thus the battle continues.

Hey Buckeye. Is it common for small ponds and lakes in that area to have zebras in them?

Our ecosystem in the south is vastly different than up north. Warmer water, and lots of predators that eat mussels.

Our Drum will eat them, our catfish will eat them, our crawfish will eat them(and we have a much larger population of crawfish here). Our Bream will eat them(they don't call them shellcrackers for nothin').

I can remember as a child the great Lakes were known(down here to me anyway) as polluted industrial waterways. This has changed dramatically.

The whitefish population has declined, is that from zebras, or the massive commercial fishing hurting the populations? Any studies on that??


There are ways around the clogging of water lines, in Europe alot of places have copper water pipes, they cannot attach to them. Expensive to replace all of ours with copper, but it is one solution. Also wrapping the legs of docks with copper in the underwater portion. Expensive but effective.

But, like noted, we still do not know how our ecosystem will react.

They bread quickly, ok, how will our natural predators react? Will that casue an explosion in crawfish populations with the increased food supply? Giant bream like in havasu?

Would stocking gobies help?

I think we need more natural answers(like stocking predetors maybe), before we start dumping more chemicals in our waters without knowing the other affects this may have.

The Great lakes are great fisheries now, they used to be the dead sea of polution, how much of this can be attributed to the positives of zebras?

Just a few things to ponder.

This is ridiculous. After the floods this year every waterway below Texoma will have mussels. Every waterway below Ray Roberts will have them. Every lake that they move water to for water supply will have them. Look at the map of how they got here. They traveled the waterways, not by boat but by flowing rivers. I will tell you up front I will never worry about mussels. They will be in all lakes if they don't find a way to kill them and draining my boat won't make one bit of difference.

I agree and disagree. Waters below infected resevoirs are always endanger of being contaminated. You have to figure the flooding hasn't helped matters. I agree.

But I disagree with the notion that nobody should drain their boats since we are already doomed. We know boats are a transmission source. Having boats create zebra colonies adjacent to boat ramps is not a good idea. Then to have boats use those boat ramps in concentrated areas without draining is even a worse idea. It is like picking up litter. It is not a big deal, and it can make a difference. Just drain your boat. Everybody needs to do their part so we can slow the spread. If we can slow them down, time can be our friend as research continues.

Once all of our lakes are choked with zebra mussels, then I can see peoples point on 'whats the point' But we are in the early stages in Texas, so draining boats can do a lot to slow the spread and buy time. I just don't see it as a big deal. I have always done it anyway, even before the mandate.

Zebra mussels will create fish habitat and destroy prey at the same time. The prey that is destroyed (like shad) will be replaced by prey that can live on the bottom. Yes, with a zebra mussel cluttered bottom, that will be good for crayfish. That is where the nutrients will be and the zebras will also provide some shelter. Zebra mussels will also become food. There will always be fish to catch, but the type of fish we catch will most liekley shift.

The predators will for sure eat the zebra mussels, but what we have learned about these mussels is that predation does not keep up with their spread. Once they get a strong foothold, they will reproduce exponentially despite predation.

Guides always tell us to follow the bait. What if the bait is gone? Then what? The ecosystem will get shaken up. The food chain will scramble, and their will be winners and losers. Winners will be animals that can adapt to bottom living. Pelagic fish will most likely be losers unless they adjust to new food sources which will create competition between species that does not occur now. It is a night mare for the ecosystem, but I agree that it will be hard to predict exactly what will happen.

This is what happened with the Hudson River.

"While the mussel's initial impacts weren't a surprise (phytoplankton also crashed in the Great Lakes), the researchers couldn't anticipate exactly how the river's complex web of life would respond. The monitoring revealed a dynamic series of shifts.

After the invasion, the team noticed that growth rates of open-water fish such as shad, herring, and striped bass dwindled in zebra-mussel infested areas. Many of these fish also appeared far from their usual habitats, moving downriver to mussel-free areas to seek food. (Zebra mussels cannot tolerate much salt, so they have not colonized the brackish estuary at the lower portions of the river near Yonkers and New York City.)

Shallow-water fish, however, benefited from the invasion. With fewer phytoplankton to cloud the water, the Hudson's murky brew became about 40 percent clearer. Light could then penetrate deeper and stimulate production of aquatic plants. Shallow-water fish that prefer weedy environs, such as sunfish and large- and small-mouth bass, actually found more vegetated habitat after the zebra mussel invasion. These fish species have grown larger and have expanded their territory. "With almost all invasion cases," says Stuart Findlay, "there are winners and there are losers.""

It makes sense that striped bass and white bass could struggle in zebra infested waters where bass and catfish may actually get their habitat expanded. I am not fearful that the fishery will go away, but it will definitely change. But that is not the major concern with zebra mussels. Our waterways are not fishing first. Zebras are not good for non fishing activities either.

Noticed that there were a good deal of zebra mussels on the flooded willows around the Crescent Oaks boat ramp. Ironically there were also a few still stuck to the zebra mussel sign. I guess with all of the water dumped from Ray Roberts they are starting to have a real presence on Lewisville.

I would like to see them in many local lakes in D/FW.

It would be nice for them to clean the water.

I don't buy the TPWD information, I see it as just another revenue source for them.

It has been proven in the great lakes that zebra's have been good for fishing

Short term it may be, but with water clarity > 10' fish are spooky. also, Bass start loosing out as bluegill no longer have the algae they once had and are more agressive feeders. Fry tend to be consumed in greater numbers resulting in smaller crops of upcoming fish.

I am going to bet that these are now in most of our area lakes following the spring and early summer flooding. Everything down stream would have them once water is released from any infected lake.

I do a weekly outdoor column in our local paper. Been involved and following zebra mussels since the 80's. Wanted to share a column I just published. Please note the last paragraph comments. May I add Mr. Allen Latham's son devoted his life to studying aquatic invasive species. Fees' closing or limiting access's but when you ask the experts might be the next step in natures change

Title:
Aquatic Invasive Species Are They Part of Natures Change?


Dave Mccurnin, a Lake Belle Taine property owner, concerned because the lake he is on is considered a high risk for aquatic invasive infestation, sent me a e-mail with a few of his suggestions to fund aquatic species efforts. His recommendation Included, five dollar fee accessed to every fishing and boating license sold. Tournament contestants, required to pay ten dollars for every tournament they are a participant. Mccurin, suggests if inspectors are not available to be at the access, it must be closed. Resorts with their own private launch areas must pay for inspectors to be present.

Dean Christofferson, President of the Park Rapids Bass Club, holds tournaments every Tuesday night on a number of lakes ”As a club we are very vigilant about AIS. We know the potential problems that could arise if we weren’t.. We go through the inspection process more then other boaters and we should. We work hard to prevent spreading of invasive species because the very thing we love to do could be at risk and will protect to the best of our abilities. A ten dollar fee to each boat in a tournament on Belle Taine, to be used to prevent the spread of AIS. Great Idea !! I’m all for it with some modification. Call it lake use fee and all using the lake should be subjected to it.” As a avid fisherman, Christofferson will approach anyone that may have weeds visible on the trailer or boat he comes in contact with.

Barry Choinard, National Professional Anglers Association Board Member and FM Walleyes Member and tournament coordinator had this to say: “I’ve always carried the message that AIS is everyone’s responsibility, as such, I don’t support a user fee approach. The amounts funded by our government entities should come from the tax paying community as a whole, not a small fraction of the population. Indeed many of the funds being used come from those sources.Continued effort to expand the tools available to fight AIS in Minnesota is the most critical element we face today. Empower the leaders to allow them to influence others. If I WANT to decontaminate my boat after a day on the water – I should be able to access a decontamination facility within 30 minutes no matter where I am in the state.Sportsman have established and funded many of the critical organized activities in our state well before AIS became near the threat that it is today, without any support from lake associations or organizations. When AIS stepped to the plate, now these lake groups want to dictate how we run our organizations and use our lakes with rules built with just a lake association point of view.

Allen Latham, Green Lake, Spicer Minnesota, a sixty year veteran geologist, in the past frequently shared notes with his close friend, the late Tom Bonde, Green Lake Spicer, Minnesota a career aquatic biologist for the Minnesota DNR, United States Fish and Wildlife Service and the United States Corp of Engineers. Both members of the Green Lake property owners association serving as past directors and president. Latham had this to say “ It is a good idea to slow the spread of aquatic invasive species. In my opinion the best way is by funding decontamination efforts . If the intent is competing or altering nature, better have a large billfold. ” Lathham added this closing thought “ nature, means change, and aquatic invasive species are part of the natural order of things. It is inevitable, so be prepared to accept that aquatic invasive species are part of natures change.”

Experts = your very first warning you are about to be ripped off.

Fees = never let a crisis go to waste. Just wait... there will be a fee for collecting the fee.

Study = figure out a way to take someones' money and transfer it to a government pinhead's wallet/retirement program.

Empower the leaders to allow them to influence others = Make people feel good about being scammed.

Another big giant pot of money seized from the working man for bureaucrats to waste away for zero results or produce the same old vapid reports of nothing.

May I add the column left off the ultimate catch phrase for draining wallets and dreaming up confiscatory guilt fees/taxes for government waste: "Think of the Children."

I have more respect for someone with the stones to come a put a gun in my face and demand my money than a committee of experts taking it by bogus fees. At least you know up front your are being robbed by a criminal.

I am solely responsible for this thought crime.

Boy did you hit the nail on the head with this one... right down to the "Think of the Children" Are you sure your not from Hawaii? Every bill in our legislature right now is adding a fee, raising a fee or increasing a tax or adding a tax... and in every public hearing I've attended, I've heard "For the Children", "think of the children" or as we say in Hawaii "But it's for da Keiki" (children) at least a dozen times in every hearing.

I've caught so many giant smallmouth in great fisheries that seem to have been largely made possible by zebra mussel "infestation" that I'm cool with replacing the bald eagle with the zebra mussel as our national symbol.

Those who complain to me about the zeebs clogging up power plant intakes and such, my reply is generally "Well, good....there's one job that can't be outsourced to India, eh?"

Just wonder how many of those zebra muscles headed downstream with all those millions of gallons of water being discharged by the dams due to the heavy rain and all the lakes being over pool. Certainly that is a hell of a lot more than what might be contained in someone's bilge water. Yes I do take the time to remove my plugs and drain my boat. i do not intend to unnecessarily spread the infestation of any invasive species and I sure as hell do not wish to be fined, but to blame boaters is purely idiotic.

Another thought. How many people do you know that launch their boat and pull out of one lake and go to another to launch. It does not sound like very typical behavior. I think most boaters use the same body of water for the most part and between launches they probably clean their boat.

So, I have see Zebras in Texoma a few years ago they were real bad. When I say bad, the casual person could see them. Under nearly every rock, and a few items floating that had them on it, we noodle, and you could feel them in every hole you stuck your hand in. when the lake dropped we started to see less and less, I am sure they are still there. this weekend at Lewisville, my wife and I were trolling and she got hung, when we pulled it up, it was an old Rod and reel (3-4 years old) It had the Largest Zebra I have ever seen (Size of your thumb, and several about that size). they are everywhere, and just cleaning a boat does not stop this. with last years floods, the battle is over, unless they find something that likes them. But I will say, the year that we saw the most at Texoma, the water was the clearest I have seen in 35 years... Hmmm

Blue cats love them and will gorge on the things. Catch a winter time Blue in Ray Roberts and it will have a belly full. Feels like gravel in it's stomach. They will sometimes puke them up in the box. Don't put blues in the livewell. Them mussels they puke up will destroy your pumps and valves. Been there done that.
The up side is there are gonna be a lot more blue cats to catch and bigger too.

True that we might as well learn how to live with them, but I am not one to pretend that this is a good thing. My guess is Shad have quite a bit more nutrition value than zebra mussels. The whitefish population in the Great Lakes has also learned how to take advantage of this new food source as their forage choices have changed. It has affected the size of whitefish in a negative way. On the contrary, bass habitat has expanded with clearer water and now a larger photic zone. Add gobies, another invasive species, to the mix, and those bass are fat and happy. Expect the food chain to scramble. There will be winners and losers.

Shad are pretty easy to catch at Lewisville at present. With clearer water coming, expect that to change in the new future. Could change the way we fish Lake Lewisville for sure.

It was inevitable... to close to Belton. A morning fishing trip in one and in less than 10 minutes later be able to launch into another.

Edit reason - Added below.

And no, no one can put any one blame on the transport cause of it getting into Stillhouse. I know drain-plugs are supposed to be open leaving Belton (ticket-able offense). But, how many kayaks, pull tubes, canoes etc that could possibly be a carrier. Just sayin'

Not to mention Floods.. Texoma was Massive a few years back, under every rock, and items were floating with them attached. last few years you barely see any (Not that they are not there) but not under every rock. I Noodle and have not had any Cuts like a few years ago.. (In the same hole..) The Lake dropped and I think that killed many that were in the shallows, and there were many..

From firsthand experience here in Oklahoma, all of our Arkansas water shed lakes have now had zebra mussels for 12 years. Sooner where I fish the most (power plant lake) the Zebras have contributed to an explosion in the drum population, this in turn has provided another source of forage (small drum) they were scarce before Zebra Mussels, secchi disk tests, have not confirmed much change in turbidity, threadfin shad and silversides(ghost minnows) seem to be thriving better, when zebra veligers are present, and these populations are on the rise. Sooner is a fairly sterile clear lake in the first place , no real inflow, except for a pump in from the Arkansas river.

We also have white perch now too as a result of Arkansas river from Kansas. The sunfish population CRASHED, anecdotally it appears to be holding steady, but no net samples to prove this. All Striper, Hybrids, Sandbass, white perch seem to be thriving, while Largemouth are getting bigger with new available forage, their recruitment is now poor, ODWC is considering supplemental stocking of all sunfish. Saugeye and catfish are also doing well -- the Zebra population seems to be lower now than when we first started seeing them, rocks are not as encrusted as they were five years ago -- I think what you CAN say is that Zebra mussels will reach a stable population, controlled by drum catfish, and threadfin shad eating veligers, you can also say that former fishing patterns will DEFINITELY change, we find most all of our fish 15-30' deeper than we did ten years ago -so now we fish 70' deep as opposed to 30' deep --its not all doom and gloom, nature adjusts - Tony Hughes, Lateral Line Guide Services Stillwater OK.
