I agree with the others. Any time i see a fish kill.. and the larger ones go first.. that is a sure sign of o2 problems. An algea bloom will do it.. fertalizer runoff or other decaying matter will increase BOD of the water and burn the 02 out of it.
Aerate or run a fountain toincrease water surface area. If water is extremly low.. you may considder adding water depending onthe size of the pond.. etc.

The smaller cats and blue gills still come for food, and there was no death since, but I have no idea why it happened. And I voted not to diasect corpses, it was hard enough to get them out of the pond.
As far as I know there were no chemical spills, we didnt have rain to wash the road in the pond recently and as I said - in 4 years I didnt see a dead fish and all the frogs are happy as ever.
Also the food is the same catfish food i use since spring.
Ideas anybody?
