Just because a pond wasn't stocked doesn't mean there is no fish in it. Green sunfish and bullheads have a way of popping up in bodies of water. I would just about bet if you put some traps in your pond you would find at least a few in it. Bull heads an green sunfish would make a snack out of the fatheads. A 1/10 acre would make a good forage pond if not inhabited by other fish. I have two ponds smaller than that for forage ponds.

I'll start treating my wife as good as my dog when she starts retrieving ducks.
