A couple of thoughts.
Tim is right about the danger of disease on introduced fish. However, due to certain character flaws, I would just have to put a couple of Lake Fork whoppers in. I just couldn't help myself. Of course, somebody else would probably have to catch them.

Fishman brings up an interesting point about going ahead and stocking bass when the forage is stocked. IN A PERFECT WORLD, nobody would try to help anyone else stock their pond. However, I have bass that are way too large (14 inch) for being stocked as crappie minnow size fingerlings last August 6. I also have green sunfish, warmouth, and yellow sunfish. None of which I stocked and all bigger than my largest bluegills. This has also happened to most of my friends and none of us believe in the bird stocking theory. As it now stands, I have no idea of the number of bass in my pond. If I had it to do over again I would probably go ahead and stock fingerling bass at the rate of 50 per acre and way too many fatheads. At least I would know something more about the bass population.
