Other common names: Bullhead, horned pout, red cat, creek cat, mud cat, speckled bullhead, and common bullhead.

Other scientific names:Ictalurus nebulosus (Armstrong 1962).


Slide28 l.jpg

Brown Bullhead ( Freshwater Fishes. 3rd Edition. McGraw-Hill, Boston. 215 pp. Ameiurus nebulosus)

  • Identification: Olive to brown with dark mottlings on sidesfading to cream/white underneath. Fleshy whiskers (barbels) dusty to black. Relatively short anal fin with 22-23 rays. Rear of caudal fin slightly notched.

    • May be confused with Black bullhead, (Ameiurus melas).

    • However, A. nebulosus has 5-8 large sawlike teeth on rear of pectoral spine whereas A. melas has none.

    • Also, A. nebulosus does not have black membranes contrasting with pale rays on caudal and anal fins.

Slide29 l.jpg

Brown Bullhead ( Freshwater Fishes. 3rd Edition. McGraw-Hill, Boston. 215 pp. Ameiurus nebulosus)

Distribution: Not common anywhere in IA, but is widely distributed in the northern part of the state. Very few found in interior waters. Most taken from the upper Mississippi backwater sloughs.

A. Nebulosus is native and common to the Atlantic and Gulf slope drainages.

Habitat: Slow moving or stagnant parts of rivers, and streams, also ponds, lakes, and pools that offer a soft bottom.

Iowa DNR

Diet: Brown Bullheads are schooling bottom feeders that feed primarily on crustaceans, insect larvae, worms, snails, crayfish, and small fish, though they will eat virtually anything available, either alive or dead. A large part of their diet is midgefly larvae, or “bloodworms” which they pick up off of the soft bottom ooze. Teeth in pads on both top and bottom jaws; used for tearing food. They seem to have ravenous appetites and will eat day or night.


Slide30 l.jpg

Brown Bullhead ( Freshwater Fishes. 3rd Edition. McGraw-Hill, Boston. 215 pp. Ameiurus nebulosus)

Reproduction: Spawn in late April or May. Males fan out a saucer-shaped nest where females lay 2,000 to 10,000+ eggs that hatch in 5-8. Both parents guard the eggs during incubation and herd young around for several weeks after hatching. Young reach 2-1/2 – 4 inches in first year and mature in 3 years. Can reach two pounds. (IA Record: 2-1/2 pounds, no specific species given though. World Record: 6 lbs, 1oz., NY)

Economic/Recreational Importance: Popular game species where they exist.

Ecological Importance:Not much due to their lack of distribution and non-predacious lifestyle.

Conservation Status: Abundant. Limit is same as catfish (?): DBL = 8 lake, 15 stream, PL = 30. No limit in Mississippi River.

Other: Can reach 2+ pounds under ideal conditions, but most commonly range from 8-10 inches and less than a pound

Conservation Status Freshwater Fishes. 3rd Edition. McGraw-Hill, Boston. 215 pp.

  • Common in Eastern Iowa

  • Population doubling rate of less than 15 months

  • Can survive harsh environmental conditions due to breathing oxygen-rich surface water

  • Is threatened in some states due to water pollution and habitat destruction

University of Michigan


Ecological importance l.jpg
Ecological Importance Freshwater Fishes. 3rd Edition. McGraw-Hill, Boston. 215 pp.

  • Preyed upon by larger fish

  • Known to jump out of the water to avoid predators

  • Hide motionless in aquatic vegetation

  • When feeding, their image reflects on the water surface. When a predator approaches, they dart one way and their image goes another way, which confuses the predator.
