Last in a burlap sack?

In the water?

In the water.......I'm just throwing a wild guess out there but I would say in a burlap sack they should last about 5 to 7 days.
In a wire basket maybe a couple.

They dissolve pretty quickly. You’re going to want the grains to hang around somehow. Burlap bags work as do “pvc feeding tubes.” If you bait an area regularly, every couple of days or so, you don’t need devices to keep the grains and the fish hanging around. Us part-timers are lucky to hit the water a couple days in a row. So, we find the devices helpful.

Water temperature also plays apart. If your water temperatures are below 60 degrees I would say they will easily stay in a burlap sack for close to 6 days or 7. If you want to give them a prolonged break down time soak the range cubes in some sort of fish oil

What we used was DollarTree laundry mesh bags and about 10lbs to a bag. If they get hit then about 3 to 5 days. Also I put a small bit of stirofoam in to float them to the top of the water when they are M/T.

Looking at a 6 day trip so I will drop one 25 lb sack then the 2nd two days later I will be be throwing out sour wheat by the scoop every 6 hours

You should do fine then

my dad was a catfisherman on Lake Kemp west of Wichita Falls...he'd drop a tater-sak half full of soured wheat and a half bukit of it and we'd fish it after a couple of hours...the cats / carp will tear up that tater sak that day and the soured wheat is gone...they'll eat it up a sack much faster than a day and the bukit full much faster than 6 hours

When I am fishing I put out range cubes to attract fish to an area fast and fish it that day and even within a few minutes of setting it out. If you ever put range cubes in a 5 gallon bucket, you will find it is 90% powder within 10-15 minutes....and thats without waves and current. If I'm trying to really bait out an area I prefer semi soured milo and the only reason I sour it at all for a few days is so it doesn't swell in the fishes guts after consumption (not sure if it would cause problems or not) but I have thrown nonsoured milo out and caught fish 30 minutes later engorged with it so I don't thinking souring it is necessary to do the trick. MIlo will stay there until it is eaten and not just dissolve away like range cubes. Food for thought.....

daddy soured it for the stink...the slim was like calf slobber...a catfish is a swimming tongue so they smell it from a longgggggggggg way off and come a runnin'...or swimmin' as the case may be...we'd ketch'm with the wheat kernals comin' out their buttt...like the guy above said, the cubes dissolve and gone in an hour, if the turdys let it sit that long

I like to throw range cubes out where I am fishing especially when I am bank fishing. I made a thrower out of PVC pipe that will throw a half dozen or so cubes. I can throw them 50 to 75 yards and scatter them out. I then fish that area.

To be honest I don’t really see a reason for the bag. I am not going to pull a wet bag of wet cubes in my boat to change locations. How I start one of my baited spots is I buy a 50 lb bag of cubes. Ok I look for a spot that has some pretty dead trees to tie my boat on and maybe a blue heron on the bank. Then I open my 50 pound sack. Then I pour the hole sack in the lake. Yes the bag is empty when I quit pouring. Then I Fish that same exact spot every time I go fishing. The fish will be there if you add a half bag of cubes each time you go fish in your spot. It is like you have a wild catfish feeder there and the fish are there. Now you can catch them on just about any bait but I use Stubbys cheese bait and my freezer is full of fillets. Now catfish will eat a whole range cube and maybe that is the reason for a bag. Yes I have used soured maze and wheat and it works great also. It has been my experience as long as you are feeding the fish often enough they will be on you hole. That is the reason your retired buddy catches more fish. He baits his spots every week and is best friends with the feed store owner. Now i don’t see a thing wrong with feeding fish and catching a few for my friends and my family but I am no peta member. I fished in a bass tourney once and had two peta members approach me about being a harm to bass. Heck you got to catch one to risk harming one and bass fishing is a young tough guy sport. I am neither young or tough so I don’t do it. I used to throw that DD22 out as far as I could about 60 times each hour for ten hours a day. My old arthritic shoulder needs a replacement and there are easier ways to have fish for a meal. Most important thing is to drown some Stubbys cheese bait at your hole and catch some fish.

I do not retrieve the burlap sack
