Blue Catfish

Blue Catfish

Blue Catfish are massive freshwater predators found in Tennessee's major river systems. These fish are opportunistic predators noted for taking injured fish beneath feeding schools of striped bass and consuming wounded baitfish washed through dam spillways.

Scientific Name: Ictalurus furcatus

Physical Characteristics:
  • Blue Catfish typically range from 25-46 inches and 30-70 pounds.
  • They're distinguished from Channel Catfish by having 30-36 anal fin rays (versus 25-29 for channels), a straight-edged anal fin, deeply forked tail, and lack of spots.

What to know

Habitat Distribution

  • Found primarily in the three major river systems: the upper Tennessee River (especially Fort Loudoun and Watts Bar reservoirs), the Cumberland River system (particularly Cheatham Lake and upper Barkley), and the Mississippi River along the western border.
  • Blue Catfish prefer open waters of large reservoirs, main channels, backwaters, and deep holes along outside river bends.

Key Locations

  • Tennessee River system's upper pools like Fort Loudoun and Watts Bar, the Cumberland River around Cheatham and upper Barkley, and the Mississippi River near Memphis.
  • Found in the Tennessee, Cumberland, and Mississippi Rivers.

Specific Spots

  • Target deep holes (30-45 feet) along outside river bends with mud bottoms during winter, as mud retains heat better than rock.
  • Key locations include tailwaters below dams, rocky bluff banks, and areas with current breaks.
  • Bank fishing from riprap areas near dams.

Blue Catfish FAQ

Answers from onWater's species guide.

What are the best lures and bait for Blue Catfish in Tennessee?

Cut skipjack herring is considered the premier bait, followed by fresh cut gizzard shad, threadfin shad, and cut herring. Live shad and herring also work well.

When is the best time to fish for Blue Catfish in Tennessee?

Winter months (December through March) for trophy fish, spring (March through May) for excellent numbers and some trophies. Avoid spawning season (May-June). Night fishing can be effective, especially during summer heat, though Blue Catfish feed actively during daylight hours when conditions are right.

How do you catch Blue Catfish in Tennessee?

Fish on or near the bottom, but Blue Catfish will suspend in open water beneath shad schools. Dr.ifting techniques work excellently, especially during summer when fish spread out in stabilized river conditions. Look for uneven bottoms and ridges where baitfish move in current.

What do Blue Catfish eat?

Blue Catfish are opportunistic predators that feed heavily on shad, herring, skipjack, crayfish, crabs, freshwater mussels, clams, worms, frogs, and other fish - including cannibalism.

Where do Blue Catfish live in Tennessee?

Found primarily in the three major river systems: the upper Tennessee River (especially Fort Loudoun and Watts Bar reservoirs), the Cumberland River system (particularly Cheatham Lake and upper Barkley), and the Mississippi River along the western border.
