How much cooper did you use, what form--granulated or liquid? I think it's no coincidence you lost fish around the same time and they are of the size one typically finds in shallow water where you treated. Maybe you sprayed them directly?

Is your water soft or hard?

I would pretty much discount oxygen issues in open cold water. I also wouldn't get too upset if they were just a few small fish and not your larger fish that are in deeper water.

How about Andry's Fish Farm? I know he delivers all over the state and is located in the southern half. He's on the web.

If pigs could fly bacon would be harder to come by and there would be a lot of damaged trees.
