Blue Catfish

Blue Catfish

Blue catfish are Oklahoma's largest catfish species, capable of exceeding 100 pounds with the state record at 98 pounds.

Originally restricted to the Red River system, they're now found throughout most of Oklahoma due to extensive transplanting and have adapted exceptionally well to the Arkansas River System.

Scientific Name: Ictalurus furcatus

Physical Characteristics:
  • These fish are distinguished from channel catfish by their straight-edged anal fin (versus rounded), deeply forked tail, and lack of black spots on their blue-gray bodies.

What to know

Habitat Distribution

  • Blue catfish inhabit large rivers and major reservoirs, preferring areas with sand, gravel, or rock bottoms over depths of 15-60 feet.

Key Locations

  • They're found in excellent numbers in lakes like Texoma, Eufaula, Grand, Keystone, Kaw, Waurika, Oologah, and many others across the state.
  • On lakes like Texoma, Eufaula, and Grand, concentrate efforts around bridges, main lake humps, and the intersection of river channels with flats.

Specific Spots

  • Focus on main lake points, channel bends with rocky structure, submerged timber, and areas where creeks enter the main lake.
  • Look for areas with current breaks, fallen trees, rock piles.
  • Large blues often suspend in deep water beneath schools of shad being fed upon by striped bass.
