I posted this last week, but will repeat it once more for your sake! I stocked a 7 acre pond with 120 4-6" white crappie, after it was well established with bluegill and bass for several years. The pond owners wanted the crappie for something easy to catch and gooood to eat. Well the next year they harvested 400 crappie in the 1-1.5 pound range. The point is, I'm with Dave, I don't think you can get away with bass and crappie and minnows of any kind. You need the high reproduction rate of bluegill to keep your pond going. I like your out of the box thoughts though. Keep thinking of what you want and manage for it. I would try stocking with bluegill at 1000/ac at the recommended time for your area then split the recommended bass stocking with crappie at the proper time, to allow the bluegill to establish. You may have to set up a feeder or two for a couple of years until the bluegill get a good foothold. Good Fishing.
