My favorite bait is fresh bunker. Not usually practical for catfishing since it means ive gotta take a ride to the beach with my cast net to get some and freezing it is absolutely useless so it has to be used the same day its caught.
Second favorite is creek chubs. Either cut or whole depending on the size.
Most over rated is definitely chicken liver. I guess if your fishing for food it can be usefull but id rather not spend a night unhooking eels and turtles.
