Blue Catfish

Blue Catfish

Blue catfish (Ictalurus furcatus) in New Mexico are native to the Rio Grande drainage but have limited presence compared to other catfish species.

They're the largest North American catfish species, reaching up to 165 cm in length and weighing over 45 kg, with lifespans of 20+ years.

Scientific Name: Ictalurus furcatus

Physical Characteristics:
  • Blue catfish are distinguished from channel catfish by their straight-edged anal fin with 30-36 rays, lack of spots, and deeply forked tail.
  • Their bodies are bluish-gray dorsally, fading to silvery-white on sides and white on the belly.

What to know

Habitat Distribution

  • They prefer deep channels and pools of medium to large rivers with swift currents and hard substrates like gravel, sand, or rock.

Key Locations

  • In New Mexico waters like Elephant Butte Lake and Caballo Lake, concentrate on areas where the main channel meets structure.

Specific Spots

  • Target deep water areas (20-30 feet) in main river channels, particularly around outside bends with structure like submerged logs, rocks, or steep drop-offs.
  • Target depths of 15-45 feet, adjusting based on season and water temperature.
  • Blue catfish are known to suspend in deep water beneath baitfish schools.
