What is different about your 3 acre pond compared to the other ponds besides depth. Not much difference that I can note.
Do all ponds have aeration? Only the pond that had the die off has aeration.
Did the 3 acre pond freeze over completely and have snow on top of the ice. The pond always had an open water spot but yes, snow did cover the ice.
Did the diffuser set at 4 foot depth keep a hole in the pond all winter? Yes
Are all ponds pellet fed? If yes is the same food used for all ponds? Two of the three are pellet fed and the same food is used.
Do you stock HSB at the same time in the ponds? From Bruce Condello “ Don�t buy, handle, or stock HSB when water temperatures are below 50. Your fish will get a nasty green fungus on their fins and may die.” The fish had been in for three years each time they died.
How old, how big and how many HSB were in the 3 acre pond before the kill as compared to your other ponds? 50 fish, three years old and most were near 20" as far as i could tell.
