Ok, I understand what you posted about the talapia, and I know your kicking around ideas. The pond that is over run with feed fish has these same large talapia and the cats. I have lived all over east coast, never have I seen a pond with so many fingerlings, the place might as well be a hatchery. If it had something to do with the talapia eating their own, would not this pond be seeing at least some effect also?
I need some help with the winter and summer forage, is that spawing for LMB to eat?
