If a catfish swallows the hook will it most likely die? Why I was wondering is because I been going to the pay lake and most the fish I caught have swallowed the hook. If I don't feel like cleaning them I will turn them loose in a farm pond close by. Thats the reason I ask. Also the pay lake is only about 3 miles from the farm pond so they ain't out of the water more than 6-10 mins. I know catfish are some of the hardest fish to kill.
