What about a 5 acre main pond with a connected 1 acre forage grow out pond. Connect them with a 6ft opening with the ability to close off the openig with rigid plastic netting/fencing. Idea is to grow out extra forage and open the gate and drive them into the main pond. Close the gate back and shock up some large tilapia and some shad and put them back behind the net and add a few select best conditioned LMB from the 1 year age class. Just a different thought.
