Brown Bullhead

Brown Bullhead

Brown Bullhead in Iowa are hardy, bottom-dwelling catfish that thrive in the state's diverse freshwater systems. These resilient fish can tolerate extremely harsh conditions including low oxygen levels (as low as 0.

2 ppm), heavy pollution, and temperatures up to 97°F, making them survivors in waters where other species struggle.

Scientific Name: Ameiurus nebulosus

Also known as horned pout, mud cat, mud pout

Physical Characteristics:
  • These fish are distinguished by their mottled brown coloration, squared-off tail fin, dark chin barbels, and sharp pectoral spines with saw-like teeth.
  • They typically grow 8-14 inches long and weigh 0.5-1.5 pounds, though Iowa's state record reached 5 pounds 8 ounces.

What to know

Habitat Distribution

  • Brown Bullheads prefer slow-moving waters with muddy bottoms and abundant vegetation, thriving in Iowa's shallow lakes, ponds, streams, reservoirs, and river backwaters.
  • In Iowa's glacial lakes, they're often found alongside black bullheads and other catfish species.

Key Locations

  • Productive Iowa waters include various Mississippi River pools, Coralville Reservoir, Easter Lake, Lake Odessa, and many of the state's glacial lakes in northern Iowa.

Specific Spots

  • Target shallow water areas that warm quickly in spring, focusing on windward sides of lakes on sunny days, areas with inflowing water, and spots near rocks and stumps.
  • In summer, avoid fishing deeper than 15 feet due to thermoclines, instead targeting 12-15 foot depths where bullheads find cooler, well-oxygenated water.
  • Fish moving back to shallow points near deeper water during the fall turnover.
