Try chumming the area with a large can of a fish based cat food. Poke holes in te can with a screwdriver and throw into area you are going to fish. Bullheads can't resist worms. Any of the other types any kind if oily fish will do the truck and chicken livers as well. I like using dead herring for channels. Nice oily bait that doesn't wash out if scent after just a few minutes if soaking.
