Yes, TZ, tell us more about your LMB. The bullheads (mudcats) are very vulnerable to LMB predation, especially when the young bullies are in those "pods" like they are right now. LMB, if present in reasonable numbers, can certainly keep your bullheads in check. They won't eliminate them, but they'll eat nearly all of the young ones, and you'll just have a few large adults (12-15 inchers) that will spawn each year, but have such low density that they really don't cause problems.
