DD said it right I have never seen a pond without bass that produce any decent size bluegill. No biggie if you don't like them but pretty much a neccisty. You might also add to the mix some Hybrid striped bass. And yes the blue cats or more predatory like but can not control bluegill reproduction. Black crappie have almost the same potential to "takeover" a pond. If 1/3 full you can this time of year go ahead and add the bluegill, redear, small channel catfish, etc. Where do you plan on buying them? I work with a hatchery in NE, AL that supplies excellent fish.
