Brown Bullhead

Brown Bullhead

A scaleless, mottled-flank catfish of soft-bottomed lakes, ponds, and slow streams across most of the eastern half of the country, with introduced populations now widespread in the West.

Brown Bullhead are the quintessential warm-summer-night fish — a starter species for many anglers and a serious target in the Northeast, where 'hornpout' fishing remains a tradition.

Scientific Name: Ameiurus nebulosus

Also known as Hornpout, Horned Pout, Mud Pout, Mud Cat, Marbled Bullhead, Common Bullhead, Speckled Cat

Physical Characteristics:
  • Olive to brown back with prominent dark mottling along the flanks fading to a yellow or white belly — the mottling is the key field mark separating it from the uniformly colored Black Bullhead.
  • Chin barbels are dark brown to dusky black; this is the most reliable way to tell it from Yellow Bullhead (white chin barbels) and Black Bullhead (solid black, no pale base).
  • Pectoral spines have 5–8 large saw-like serrations on the rear edge — you can feel them by running a finger along the spine. The corner-of-mouth barbel reaches well past the pectoral fin base.
  • Most adults run 8–14 inches and a pound or so; a two-pound fish is a good one, and the IGFA all-tackle record stands at 7 lbs 6 oz.

What to know

Habitat Distribution

  • Native to Atlantic and Gulf drainages from the Maritimes to Alabama, plus the St. Lawrence, Great Lakes, Hudson Bay, and Mississippi basins; introduced and well-established across much of the West, where it was among the first fish brought to the Pacific coast in the 1870s.
  • Soft-bottomed lakes, ponds, reservoirs, and slow-moving streams are the core habitat — sand, mud, or silt substrate with submerged vegetation. Less common in fast or rocky water than other catfishes.
  • One of the most pollution- and oxygen-tolerant freshwater fish in North America: survives water up to 97°F, dissolved oxygen as low as 0.2 ppm (gulping air through the swim bladder), and tolerates brackish tidal marshes.

Specific Spots

  • Soft-bottomed coves and weedy shallows are the daytime forage flats once light fades — bullheads cruise these areas after dark, working the bottom by smell.
  • Daytime hideouts: undercut banks, root tangles, submerged logs, rock overhangs, and any woody debris pile in pools or sluggish runs. Fish stage tight to this cover until dusk.
  • In spring, look for pre-spawn schools moving into shallow vegetated bays and around any large bottom object — logs, rocks, even tires and concrete blocks — which become nest sites.
  • Brown Bullhead tend to hold deeper and reach larger sizes than the other bullheads, so a slow drop-off into a soft-bottom basin is a good place to find better fish.

Brown Bullhead FAQ

Answers from onWater's species guide.

What are the best lures and bait for Brown Bullhead?

Nightcrawlers and earthworms are the bait, by a wide margin. Roughly two-thirds of trophy-class bullheads in tracked records come on worms, and pungent compost-pile worms outfish store-bought.

What do Brown Bullhead eat?

Bottom omnivores that locate food almost entirely by smell and the chemosensors in their barbels, this is why scented natural baits crush them and artificial lures rarely do. Anything pungent and sitting on the bottom is in play.

Where do Brown Bullhead live?

Native to Atlantic and Gulf drainages from the Maritimes to Alabama, plus the St. Lawrence, Great Lakes, Hudson Bay, and Mississippi basins; introduced and well-established across much of the West, where it was among the first fish brought to the Pacific coast in the 1870s.
