I have caught them on about everything.

My go to bait in the marina on Holt Lake was hot dogs. A 1/2" piece on a tiny hook would catch channel cats all day and blues when we baited them in with cat food. I caught two blues on consecutive casts that were over 25 lbs one night. Sprinkle the cheapest hot dogs with garlic salt, let it sit in the sun a little to dry out and toughen up and you were good to go.

Large bream heads work most places but never did work there in 4.5 years. I tried a lot and never got much on them. Ivory soap works as do green grapes, white raisins (they look like grapes after an hour in the water), worms, minnows, cut bait, dough balls from any bread, and french fries with Mr. French Fry salt.

Never used taters. Never heard of using them or would have tried them.
