I would like to make a small pond to raise blue gill or red ear sunfish in to get them to a size that the green sunfish would not eat when I would transfer them to the lake. Would feed but would have no air. My pond or mud hole would be 20 feet by 100 feet, 5 foot deep. How many fish could I raise in this size pond to get them to 3 or 4 inches. If someone has tried this and found it to be a waste of time please let me know? Would a above ground swimming pool work if I would put air and a self feeder with it? Would put fish in spring and take out in fall or would I be better off just buying larger fish?

61 acre water shed lake. bass, channel cat, black crappie, wiper, walleye, redear sunfish, blue catfish and bluegill. To many bullhead and common carp
