Donnie sorry about your loss. Could you estimate how many pounds of fish you hauled off and how much is left. Just guess. Also tell us what you stocked and when. The reason I ask is ponds with large fish populations (lbs per acre) are more likely to have problems like yours. The closer a pond is to an aquaculture operation the more likely that a problem will occur. We have to remember when stocking and harvesting fish to account for growth and reproduction in the system and subtract harvest and natural morts. See these excellent links - Good for all of us to review them.
