Would it be a good idea in a small pond (1/3 acre)to add a bass or two every year or two caught from a diff. body of water just to keep the gene pool varied? Or does years and years of the offspring breeding with eachother make no diff. ? would this be the same or diff. for a larger pond also...? Could this be one reason some hatchery fish seem "a little off" compaired to wild fish?

What do you guys think? Kevin
