I don't think 800 lbs of feed is overkill for a 5 acre pond (160 lbs/acre). DPSMESA thought he fed 5 bags last year. If 50 lbs/bag, then a little over 350 lbs/acre
Also 20 CC per acre, is a modest stocking rate that is very conducive to rapid CC growth in Jason's pond. Aside from the differences in the CC, it is the differences between the water and populations that are also very important for comparison. There are 20 CC to the acre in Jason's pond and 107 CC to the acre in DPSMESA's pond. There are 142 feed trained LMB to the acre in DPSMESA's pond. Jason, I don't recall your LMB stocking density but it seems it was restricted to complement the goal of trophy LMB. Jason's pond is one year younger since initial stocking. Jason's pond is older and refurbished and may contain more native nutrients driving more production of natural foods on a per acre basis. To get comparable results requires similar conditions and population densities.
