Bullheads are hard to beat as catfish bait. They can live in less than good water, breed like rats, and take quickly to feed.
My experience with BH is, while they may spawn large numbers of fry, those fry are almost, if not entirely decimated by everything else in the pond. I used to see swarms of small BH, 30-40 per group, from 3-5 inches long. But since I've got my other fish established, I haven't seen a single swarm. There's still BH down there but I haven't caught anything shorter than 11" in quite some time. I expect that eventually, all those adults will die of old age, if they dont get a grease bath first.
