How big is your pond? Is it a natural pond?
I did not have any fish loss this winter, but the ice has never been thicker on my pond.
There is a lady that I work with and she and her husband have an 8000ish gallon farm pond. They said when all the ice was finally off their pond that they had a lot of dead fish on the top of their pond. They lost all of the fish - so I think with this winter being as miserable as it was, that we will hear more about fish loss from the winter.
