I was a comercial fisherman for years ,the reason the fish are dieing is the way they are touched ,we learned that if you handle them at all you are wipeing the slime off them and they will die,these were carp and catfish and they are alot tougher than bass or walleye, you would think that the dnr knows this too,now I guide fisherman and I tell them if you are going to let it go don;t touch or even bring it in let it go in the net just my 2 cents
