It is alot of fish but if you assume 25% mortality/fishing after the first year and GG and cats at 1.5 Lbs and Bass at 1 lbs the biomass is 4500 per acre which although is much higher than anything we consider here, it is consistent with what is recommended in their catalog(at the high end) for a fed and aerated pond.
Remember everyone we are discussing maximum stocking rates, I stocked 2500 GG in a 3.5 acre pond and did not get a sales job by Ken to stock more.Ken knew I could not aerate(no power) and I would sometimes go a couple weeks not going to the farm and so maximum stocking was never even discussed.
