I thought I'd post an update... This past Thursday(full moon) I went for a paddle around the pond. I found more bluegill beds than ever, but didn't see any fish on the beds. Instead, what I found was dead bluegill around the pond. I've picked up 27 in differing states from still slightly swimming near the surface to half decayed since then. 22 of the fish have been been 1/2lb and up. The other 5 were 3-4 inches. I captured one that was still swimming a few minutes ago and am attempting to attach pics. I also have bass spawning in the pond and they appear normal.

I'm lost as to how to minimize the loss.
