Black Bullhead
A catfish of muddy water and slow current, the Black Bullhead thrives where most gamefish struggle — silty farm ponds, prairie creek backwaters, oxbows, and warmwater impoundments across the Midwest, Great Plains, and Mississippi Valley.
It's the fish that introduces a lot of kids to catching dinner, and it remains a serious option for anglers who don't mind getting their hands a little slimy.
Scientific Name: Ameiurus melas
Also known as Black Bullhead Catfish, Mud Cat, Mudcat, Yellow Belly Bullhead, Yellerbelly, Horned Pout, Black Catfish
- Dark olive to slate-brown back with a green-gold sheen on the flanks and a pale yellow or white belly; only juveniles and spawning males are actually black despite the name.
- The single most reliable ID mark: all four pairs of chin barbels are fully dusky to black — Yellow Bullheads have white/yellow barbels, Brown Bullheads only lightly pigmented ones.
- Tail is squared off with a slight notch and often a pale crescent at its base, separating it from the deeply forked tails of channel and blue cats; pectoral spines lack the strong saw teeth of Brown and Yellow Bullheads.
- Most fish run 8–14 inches and a pound or so; a 3-pounder is a genuine trophy, the world record sits at 7 lbs 7 oz, and the species can technically reach 24 inches.
What to know
Habitat Distribution
- Native across the Great Lakes, Hudson Bay, and Mississippi basins, from the southern Prairie Provinces down to the Gulf and east to the lower Great Lakes; widely introduced into the arid West and Pacific Northwest, where it's considered an invasive pest.
- A low-gradient warmwater specialist — pools, backwaters, oxbows, farm ponds, slow rivers, and small impoundments with mud or silt bottoms. Avoids fast water and clean gravel.
- Tolerance is the species' superpower: handles low oxygen, heavy turbidity, brackish water up to about 10 PSU, and temperatures from the upper 40s to the mid-80s°F, letting it dominate water that's marginal for bass or bluegill.
- Genuinely rare or absent across much of the Northeast and Mid-Atlantic; in those regions any bullhead you catch is far more likely to be a Brown Bullhead.
Specific Spots
- The deepest hole in a pond — often near the dam or spillway — is the single best starting point, especially in fall and winter when fish school tightly into thermal refuges.
- In rivers and creeks, skip the riffles and runs entirely. Work the deepest pools, slow eddies, and muddy backwaters where current barely moves.
- Mud-bottomed shallows with weed cover, downed wood, or undercut banks hold fish through the warm months, particularly after dark when they push in to feed.
- Confined structure — outlets, dam faces, pier pilings — concentrates inactive fish during daylight hours when adults are largely shut down.
Black Bullhead FAQ
Answers from onWater's species guide.
What are the best lures and bait for Black Bullhead?
Nightcrawlers and garden worms are the day-in, day-out best bait, the majority of trophy-class bullheads are caught on them. Inflating a worm with a worm blower lifts it just off the bottom for better visibility and scent dispersal. Chicken liver is the top alternative bait; the strong blood scent pulls fish in fast.
What do Black Bullhead eat?
A bottom-up omnivore living on aquatic insect larvae (especially midges), small crustaceans, snails, worms, fish eggs, and the occasional small fish. They'll scavenge dead material readily and take live prey when it's available.
Where do Black Bullhead live?
Native across the Great Lakes, Hudson Bay, and Mississippi basins, from the southern Prairie Provinces down to the Gulf and east to the lower Great Lakes; widely introduced into the arid West and Pacific Northwest, where it's considered an invasive pest.
