Pond Boss Forums MANAGING AN EXISTING POND Corrective stocking Advice on this possible "crappie" mistake!

Its ok he put them in there, he built it. He just didnt know better. He has them in his pond and loves to catch them and them. I just dont want to have a million of them. Dont you need a mass reproducing fish like BG or these to maintain LMB? Im not killing everything so any other ideas?
