Kind of stumped me also. Did you see my last fish ID post? This reservoir is really strange. It is 6 acres, built up on a hill, it literally looks like a giant mound, has 12 aerators running in it, and we catch some really odd hybrids. We catch a lot of regular bluegill but about half of them you can tell are hybridized. I was just curious what everyone thought. Thanks for your response.
