Brown Bullhead
Ameiurus nebulosus
The brown bullhead is a smooth-skinned catfish with a mottled, brownish body and whisker-like barbels around the mouth. It lives in slow-moving ponds, streams and rivers throughout the Chesapeake Bay watershed.
Appearance
The brown bullhead grows to about one foot long, but can be as long as 20 inches. Its olive or yellowish-brown body is mottled with brown or black. It has a yellowish-white belly. It is smooth-skinned with a broad, flat head and four pairs of dark, whisker-like barbels around its mouth. Sharp spines appear on its dorsal and pectoral fins, and its tail fin is squared.
Feeding
Brown bullheads are bottom-feeders that eat algae, insects, mollusks, crustaceans, crayfish and other fish, using their long barbels to taste for prey.
Predators
Larger predatory fish may prey upon brown bullheads, especially young.
Reproduction and Life Cycle
Spawning occurs from April through June. The parents build a nest in a dark, protected area such as under a rock or inside a hollow, submerged log. The female lays her eggs into the nest. Both parents guard the eggs and young. Brown bullheads can live as long as 7 years.
