Got a question here for a man I think his name is ( Rainman ). How many tilapia do I need to wipe out a heavy algae problem in a 8/10 acre pond? What size must tilapia be to avoid predation. I have a friend who is raising and breeding some blue tilapia and he has 100's of babys to give me. I have a 600 gallon pond that I thought I could raise some up in if you think it is feasible. The pond I would be putting them in has a heavy population of green sunfish and a decent population of bluegill and bass. Any help would be appreciated. Thanks
