Your aeration may indeed have killed them all but I'm more concerned with your initial stocking plan. You stocked redears and hybrid bluegills. Redears spawn once annually and the Hybrids rarely. You have no forage base for the bass and catfish. When you start over, try 750 bluegills and 250 redears and a different aeration plan.

Like Cecil says, most of us have screwed up the first time and I have done it subsequent times. I have started calling my screw ups experiments and character builders. I still have more of them coming.
