This taken from Culture and Propagation of Striped Bass and it's Hybrids:
In a paragraph describing semi-intensive production trials, "In the South Carolina studies, stocking densities ranged from 2700-4800 fish/acre with phase II fingerlings averagint 1.8 fish per lb. After 10-12 months of culture, fish averaged 1.9 lbs, with survival ranging from 93%-96%. Production levels were related to stocking density, with 8655 lbs per acre produced at the highest density."
This is not an example of what the "average" pond-owner should try. This is an example of the potential only. Do not try this at home. Warning signs everywhere.
BUT, 1000 lbs of fish per acre with good aeration is completely sustainable....sustainable....sustainable. Of course that statement is based on some assumptions, like...yes there will be water in the pond during the summer, yes good water quality is important, etc. 100% survival rate is not expected. This is hard to control, but you'd have to stock enough fish initially to counter 3-5 years of mortality.
