Rdinson, yes bullheads do taste pretty good. The "problems with them in a pond is that they not only breed beyond any control, they also muddy the water which destroys the ecosystem needed for the primary fish most desire.
Channel Catfish rarely have recruitment of young in a pond and need to be re-stocked periodically and do not muddy the water while eating like bullheads.
There are several people that have ponds just for Bullheads.
