Hey folks,
There may not be an easy answer to this so I'll just put it out there and welcome your thoughts.
I have a small pond (40' x 40') that I've recently stocked with fatheads for foriage and occasional trapping for fishing excursions away from my pond.
I trapped them in another nearby pond where there are gazillions of them.
So far I've put in about 12 dozen, or a gross. Should that be enough of them to get a population going? Right now I have only one fish in my pond, a 12" Brook Trout.
