I never grew up fishing for bass but rather fishing for catfish and have always liked them. It seems like catfish should control bluegills easily. The only problem with this combination is that the catfish wouldn't successfully reproduce. With the thousands (millions?) of catfish raised, they are really cheap to buy. If they can control bluegills, why wouldn't they be able to control crappies? Again, I'm assuming a put, grow and harvest catfishery. In small lakes, this would not cost that much.
