If you let the water sit in the container at least 24 hrs the chlorine will be gone. This should give them a better chance of survival.

I've mounted and piped in a 500 gph aerator to help keep them alive.

This one will only be used to transport perch, crappie, cats and MAYBE a few bass used to stock private waters.

Don't want to rain too hard on your parade...but BEFORE trying to explain yourself to a judge, it might be best to check the laws with respect to the capture, transport, and use of fish taken from public waters with just a fishing license.

Somewhere out there is somebody that can quote some verse and numbers of state wildlife code, but basically the law allows you to catch bait by certain methods for certain uses, lets you catch and eat some fish, and MAY let you take SOME species of fish for use in private lakes and ponds. There are a LOT of restrictions, not just the source water, but especially with respect to certain species of fish and what you intend to do with them.

In particular the state is very touchy about certain species such as largemouth bass, flathead catfish, black and white crappie, grass carp, paddlefish, and tilapia and that's just a few of the fish. You can add many, many others you may "pick up" either purposefully or accidentally in the public waters of Texas that are expressly prohibited from possession for ANY reason. Just a few examples: Brazilian elodea, hydrilla, zebra mussels, etc. as well as certain frogs, toads, newts, turtles, salamanders, and a host of endangered or exotic species. Get caught with one and its same as anything else, you'll be checked for everything.

Its a convoluted mess to navigate. But you can take a certain size and number of largemouth bass, for instance, to kill and eat, but certainly not to transport alive into private waters. The same is true of any designated "sport" species in Texas. Take any money or other valuable consideration for doing so and the crime becomes greatly elevated.

Better look into that before using a small bottle of oxygen with a regulator and diffuser to properly deliver oxygen to the fish you are carrying in water you got from the tap and dechlorinated using the stuff you bought at Petsmart or Wally World in the tropical fish section. Then you were prepared with a cooler and some ice to cool the water in the container if it is much above 80 degrees. Plus about half pound of non-iodized salt per hundred gallons.

Better yet, get the fish you need packaged for carrying or delivered to you from a licensed, Texas fish hatchery.

I spoke with the Eastland county game warden ( he's over the county where I'm catching them from ) about transporting live human caught lake fish ( mainly crappie, cats & assorted perch ) from a public lake to a different county into private waters. Then called the Palo Pinto Co game warden ( as I'm going back into his county ) about the whole situation.
Both of them said there is no issues of transporting game fish that's been caught from public water to private waters. Said they have no concern if they are kept for consumption or used for private stocking purposes.
I can not vouch for the exact wording of the law books BUT I can vouch for what these two different county wardens told me. Even had the Eastland Co warden Check out my set yesterday as I was at the lake.

I stand corrected.

Now, How do you get around the dry livewell rule?
