Habits and Habitat
Adult black bullheads are bottom feeders, preying mostly on crayfish, aquatic insects, and fish. Black bullheads are found in streams, deep pools, and oxbow lakes. They are also found in reservoirs but do better in smaller water areas. Spawning for the black bullhead varies starting from early spring lasting through the summer when water temperatures are 68ºF to about 72ºF. Unlike other fish, the female usually constructs the nests and will guard it first before the male, and continues to guard it after spawning takes place. Like green sunfish, bullheads often colonize new ponds from existing water bodies and overpopulate and compete with bass and bream.
