Actually, in a 1 acre pond you will have no loss of recruitment with maximum harvest of female bluegill. The number of female bluegill is not the limiting factor. The actual limiting factor is numbers of appropriately sized zooplankton available for the fry.. And I have practiced it in a vacuum many times. It works 100% of the time. Or at least has so far....
If you assume having a remaining 400-600 adult fish after harvest, you would never have to replace more than 100 fish via recruitment to maintain a fishable population. Just a couple of dozen surviving females will produce hundreds of thousands of young fish to fill that void. So harvest away. There are several good threads on this forum regarding sexual ID of adult bluegill. The nice thing is you can be wrong every once in a while and still be OK.
