There you go ewest.
200 HSBs per acre, averaging 5 lbs ea = 1000 lbs per acre. This amount of fish biomass is completely sustainable with an aerated pond...easy actually. What the guy does after reaching this goal is up to him.....but harvest would be advisable to allow for further growth of the remaining population and for restocking.
Easy...stock them, feed them, catch them, eat them, restock them. Not complicated or pushed from the fish dealer.
