3z, when the first die-off occurred, we hadn't had rain in weeks. The water clouded up like it does when turnover occurs, and I observed some small, struggling fish in the shallows before the casualties started showing up. Then it just persisted--even after a 2+ inch rain. I thought O2 depletion affected the larger fish. Aside from the grass carp, the biggest fish in my pond are the HBG. It must be those tough GSF genes making them survive.

Bill, I am worried about having few predators. I did have an opportunity to get some more WE and some HSB but decided to wait until I'm satisfied this event is over. I guess this will allow my FHM to rebound and give my HBG's more room and opportunity to grow even bigger.

It's been sad for the last two weekends to see all the buzzards circling my pond and landing nearby. Honestly though, the numbers aren't huge--probably just over 100 that I've found.
