So we just dug a new 1/3 acre pond at our house last August. It filled with water this spring so we debated abotu when to stock it, and we just did so last saturday (june 8) on the last fish day for spring in Columbus, Ohio. It seems like we are losing a lot of fish... maximum depth is 12 feet, with a pea gravel lined shallow end and a beach so it will be nice for swimming. We put in fish structures and we have an aerator/bubbler system running..water temp at the surface is 78 degrees--too warm? I'm really concerned why all the fish might be dying. It's mostly minnows and redear sunfish (33 since saturday out of 200), a few bass... anyone have any ideas? Am I doing something wrong?
