This is an old post but to me is an important topic. Why wouldn't channel catfish correct stunted populations of green sunfish, crappie or bluegills? Cecil, I think you said that channel cats have to be about 2 lbs to really hit these species hard. It seems that 1-2 lb. channel cats are easy and cheap to buy. This sounds easier, cheaper and more fun than draining and killing all of the fish. The big question is, would it work?
