Are those adult LMB the biggest fish in the pond? If so, could a low DO event have happened that only affected the largest fish in the pond? Unless something drastically changes, a low DO event usually won't be just one night.........


What size were they when they were introduced to the pond? What size are they when they are dying? Any idea what age the fish are?
