Overview
The “Brown” Bullhead may vary from yellow, brown, or chocolate brown to olive, gray, or bluish black. The sides are often lighter and may be mottled with brown blotches. The belly is yellow or white. Very round brown bullheads are jet black and are often mistakenly believed to be Black Bullheads (A. melas). Color is an undependable distinguishing characteristic at best and it is important to observe other physical characteristics in order to make a positive identification. The Brown Bullhead and the Yellow Bullhead (A. natalis) have sharp, tooth like serrations along the rear edge of the pectoral spine, located at the top of the pectoral fin. The Black Bullhead lacks any such serrations or has extremely weak serrations that are negligible by comparison. In the Brown and Black Bullheads, the tail is squarish (truncate) or slightly emarginate, while in the Yellow Bullhead it is slightly rounded. The Brown Bullhead is frequently mottled while the yellow is never mottled. Its chin barbels are yellow, buff, or pale pink in color (the upper barbels are light to dark brown). In the Brown Bullhead, all of the barbels are dark brown to nearly black. In some cases there may be a pale yellowish or white color at the base of the chin barbels.

Habitat
The Brown Bullhead is native to the eastern U.S.A. (both sides of the Appalachians) and southern Canada, but has been widely introduced elsewhere. It occurs in larger and deeper waters than other bullheads.
Diet
Brown bullheads are omnivorous, feeding primarily on benthic invertebrates such as insects, worms, and crayfish, as well as small fish, amphibians, and plant material. They are nocturnal bottom-feeders, using their barbels to detect and consume food in murky waters, often scavenging for dead organisms.
Behavior
Brown bullheads are primarily nocturnal, hiding in mud or under cover during the day and becoming active at night to forage. They exhibit territorial behavior during spawning when males aggressively guard nests. These fish are generally solitary but may form loose groups in areas with abundant food, and they rely on their barbels for navigation and feeding in low-visibility environments.
Fishing
It is small at around 5 lb (2.27 kg), but is an extremely popular panfish. The meat is firm, reddish to pink, and of excellent quality and taste. It is also a popular fish stocked in farm ponds.
Conservation Status
Listed as Least Concern by IUCN.
