What are good baits to use for each type of catfish?
Catfish, one of my favorite subjects. You listed Flathead catfish first, so we can start there. Flatheads tend to be more predatory than scavenger fish so I prefer using live bait. Large minnows, chubs, sunfish, bluegills and even gold fish are all very good baits for Flatheads. For Channel catfish live bait works as well, but I have personally had my best luck using chicken livers at night. The funny thing about channel cats is that I have actually caught them with crankbaits while bass fishing. It was a heck of a surprise the first time it happened. For Blue catfish I prefer cut baits that are a little oily such as mackerel, herring and such. Punch baits, stink baits, blood baits and worms will all catch catfish as well, but I find they are usually best for yellow or black bullheads. Before anyone yells they also work for channel and blue cats as well. Good luck and I hope you catch a big mess of fish!
