Blue Catfish

Blue Catfish

Blue Catfish are native to the Mississippi River basin, including Arkansas' Arkansas River system, where they have adapted well since introduction.

These are the largest North American catfish species, capable of reaching over 100 pounds and living 20+ years, with typical fish ranging 25-46 inches.

Scientific Name: Ictalurus furcatus

Physical Characteristics:
  • They're distinguished from channel catfish by their straight-edged anal fin (vs curved), lack of spots, and higher anal fin ray count (30-36 vs. 25-29).
  • Typical fish ranging 25-46 inches, capable of reaching over 100 pounds.

What to know

Habitat Distribution

  • Blue cats prefer open waters of large reservoirs and main river channels with swift current, occupying depths from shallow spawning areas to 30-45 feet in winter.

Key Locations

  • Lake Ouachita, the Mississippi River along Arkansas' eastern border near confluences with the St.
  • Francis, White, and Arkansas rivers, and the Arkansas River system.
  • For Arkansas' best blue catfish waters, focus on the Mississippi River system, Lake Ouachita for trophy potential, and the Arkansas River pools for consistent action.

Specific Spots
