Blue Catfish

Blue Catfish

Blue Catfish are Alabama's largest catfish species and among the most prized freshwater gamefish in the state.

Scientific Name: Ictalurus furcatus

Physical Characteristics:
  • These fish are distinguished from channel catfish by their lack of spots, deeply forked tail with pointed lobes, straight-edged anal fin with 30-35 rays, and bluish-silver coloration that transitions to white on the belly.

What to know

Habitat Distribution

  • Blue catfish are native to the Mississippi, Missouri, and Ohio river basins but have expanded their range in Alabama through introductions.
  • They now inhabit most major tributaries of the Tennessee and Mobile Rivers, as well as the Blackwater, Chattahoochee, and Yellow rivers.

Key Locations

  • Wheeler Lake (known for producing trophy fish over 50 pounds), Lake Guntersville, Pickwick Lake, Wilson Lake, Lake Martin, Holt Reservoir, and the tailwaters of major dams like Mitchell Dam on the Coosa River.
  • On rivers like the Alabama, Chattahoochee, and Coosa.
  • Target the submerged locks of the old Muscle Shoals Canal system.

Specific Spots

  • Blue catfish prefer deeper waters with current, unlike flatheads that associate with structure.
  • Focus on deeper holes with current, dam tailwaters, and areas where tributaries meet main rivers.
  • Fish near creek mouths, ledges, and drop-offs adjacent to main river channels.
  • Blue catfish often suspend in open water and don't rely heavily on bottom structure like flatheads.
