Lee, the number you are quoting is a generalized number. Cecil can beat it badly because he is a professional who intensively manages and does it for a living. However, for most of us a pond can only hold a certain biomass without consequences. We are looking for a balanced pond where predators and prey pretty well maintain an approximate status quo over time. In my case, I started with a one acre pond that I think was pretty well balanced. Then the catfish went on a serious growth streak and quit biting Next, no rain and I have a 1/2 acre pond and really need to get some hook wise catfish out. Two forage ponds have dried up. Bass survival and growth? Who knows? Had I been fertilizing, it would have been a real disaster.
Bottom line. I would probably rotenone the pond, turn it into a swimming pool, throw Lusks book away and never pay another divorce lawyer. That stuff is serious.
