Mine is probably a very unpopular opinion here on the forum but I am a firm believer that you can control BC populations easily in a small pond as long as your not afraid to eat a bunch of them without them being 15" slabs, even a smaller BC will make a nice little fillet and some of the best eating there is.

I know this because I have controlled their numbers, even white crappie that don't make as nice a fillet, and seem to be much more prolific to spawn, and I ate like a king.
