Blue Catfish

Blue Catfish

Blue Catfish are one of the largest freshwater fish species in North America and are native to the Ohio River basin in western Pennsylvania, including portions that flow through Ohio.

Scientific Name: Ictalurus furcatus

Physical Characteristics:
  • Adults typically reach 30-40 inches and 20-40 pounds in Ohio waters, though the largest recorded Ohio specimen weighed 96 pounds.
  • Blue catfish have a deeply forked tail, light gray or silver coloration with a blue overcast on their head and back, and lack the black spots found on young channel catfish.
  • They can be distinguished from channel catfish by their longer anal fin (30-36 rays) with a straight bottom edge versus the rounded edge of channel catfish.

What to know

Habitat Distribution

  • In Ohio, they are found primarily in the Ohio River from Portsmouth downstream to Cincinnati, where they feed in areas with relatively swift currents.
  • Prefer large rivers with swift currents, feeding in deep channels or pools where they can ambush prey.

Key Locations

  • Target the Ohio River from Portsmouth downstream to Cincinnati.
  • Focus on areas with swift currents, deep channels, and holes near dam structures where baitfish concentrate.

Specific Spots

  • Fish in 15-45 feet of water, targeting outside river channel bends with submerged cover like stumps, laydown logs, and large rocks over mud bottoms, which hold heat better and attract baitfish.
  • Target drop-offs, dam tailwaters, and areas where barges load grain.
