Blue Catfish

Blue Catfish in Kentucky are the largest member of the catfish family, capable of growing over 55 inches and weighing more than 100 pounds with a maximum lifespan of 20-25 years.

Physical Characteristics:
  • They're distinguished from channel catfish by their forked tail, straight-edged anal fin with 30-35 rays, and slate blue coloration on the back shading to white on the belly without dark spots.

What to know

Habitat Distribution

  • Blue catfish are primarily large-river fish, preferring main channels, tributaries, and impoundments with strong current and rocky bottom habitat.

Key Locations

  • Kentucky Lake, Lake Barkley, the Ohio River, Cumberland River system, and Tennessee River system.
  • The tailwaters below Kentucky Dam and Barkley Dam being particularly renowned for trophy-sized fish.

Specific Spots

  • Focus on outside river-channel bends with submerged cover including stumps, logs, and rocks over mud bottoms in 30-45 feet of water during winter.
  • Target areas with current breaks along river channels, particularly where creek channels intersect main river channels.
  • In reservoirs like Kentucky Lake and Lake Barkley, target deep ledges, humps, and channel edges during summer months.

Blue Catfish FAQ

Cut gizzard shad (preferred by experienced anglers), live fish, skipjack herring, cut skipjack herring, nightcrawlers, prepared stink baits, and chicken livers.

What do Blue Catfish eat?

Blue catfish tend to eat fish earlier in life than other catfish species, with individuals as small as four inches consuming fish.
