It's rare that private ponds or lakes ever have enough bluegill taken out of them to remain in proper balance. If you dont have a healthy bass population to keep them under control, bream tend to typically get out of hand pretty quick and become stunted size wise.
This is wrong information. Pond management is my business (been doing it for 13 years) and I have seen two ponds that were overcrowded by bluegill.
More times than not, there are not enough bass harvested out of ponds. The bass keep the bluegill in check, but there is nothing to keep the bss in check except us
I manage two 30 acre lakes in South Carolina. One we started from scratch and is one of the bet lakes I have ever seen. There has never been a bluegill taken out and the lake is I think 8 years old. The other lake already had fish but when we started managing it, any and all bluegill harvest ceased. This lake too is incredible.
Just think about it. What do bass eat?? Small bluegill among other things. Why would you take away the food producers by harvesting your big bluegill ?
