Cecil, you have a guide of carrying 12 pounds of fish per gpm of water flow. Is that a rough rule of thumb based on the dissolved oxygen only or the flow rate of the water entering the pond. I do not understand what the primary factors are. In our 1/3rd acre pond, we calculate we have 900,000 gallons of water. We also run an aerator. Two years ago when we first installed the aerator (2 heads and a 1/4HP pump) we consistetly measured 9-11 ppm DO throughout the fall and into mid summer when our last batch of fish went bely up due to the warm water. This was when our depth was only 4-7 feet. It is now 12-15 feet on roughly 1/2 or more of the pond due to recent excavation.
Cecil, do you run a water pump for your well?
