As usual, I was typing (more slowly) while someone else was giving you a reply.

I agree with ML.

A pond with stunted bass, or even stunted crappie, is going to create an incredibly high CPUE.

For a kids' pond, that may be exactly what you want. There would be times during the cycle where every cast would probably catch a 10" bass. However, that would be tough on you (and the fish) to sustain. You could then cull aggressively, and manage the pond for different subsequent goals?
