No aeration and I know that would help but people did have ponds for years with no aeration....and probably also had fishkills
Aeration is not really feasible due to location from the barns unless they make solar ones (like the solar things that charge a car battery?).
Pond was originally 14 feet deep in the deep end and is now around 12 based on testing.
My uncle said today the turkey vultures are having a field day with all the dead fish I pulled out and put on the banks.
