Blue Catfish

Blue Catfish

Blue catfish are the largest catfish species in North America and Indiana's most limited catfish in terms of distribution.

These silvery-blue fish with white bellies and deeply forked tails are big-river specialists that are highly migratory, moving upstream in spring and downstream in fall in response to water temperature changes.

Scientific Name: Ictalurus furcatus

Physical Characteristics:
  • These silvery-blue fish with white bellies and deeply forked tails can be distinguished from channel catfish by their straight-edged anal fin with 30-35 rays and lack of dark spots.

What to know

Habitat Distribution

  • In Indiana, they're found exclusively in large rivers and streams, particularly the Ohio River and lower portions of the Wabash, White, and Patoka Rivers.
  • As big-river specialists, they prefer deep, swift channels and flowing pools.

Key Locations

  • Fish the Ohio River, particularly around McAlpine Pool near Jeffersonville, and the lower Wabash and White Rivers where blue catfish are documented.
  • Found exclusively in large rivers and streams, particularly the Ohio River and lower portions of the Wabash, White, and Patoka Rivers.

Specific Spots

  • Focus on outside river bends with submerged cover like stumps, logs, and rocks over mud bottom, which retains heat better than other substrates.
  • They prefer hard bottoms containing rip-rap or large rocks, though they also inhabit areas with mud or silt substrates.
  • Focus efforts on tailwaters below dams where current concentrates baitfish.

Blue Catfish FAQ

Answers from onWater's species guide.

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

The most effective baits are cut skipjack herring, gizzard shad, and live or fresh-dead baitfish - skipjack herring is considered premium bait when available. Other productive baits include nightcrawlers, chicken breast, white suckers, and bluegills used as cut bait.

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

Target during late fall through early spring for best results, particularly December through March when trophy-class fish are most active. During warmer months (April-May), try drift fishing or jugging. Avoid fishing during spawning season (mid-June through July) when males are guarding nests and feeding minimally.

How do you catch Blue Catfish in Indiana?

Use heavy-duty bottom fishing rigs. During warmer months try drift fishing or jugging with live shad in 10-15 foot depths along rocky channel banks. Target inflowing creek mouths during high, muddy water conditions. Focus efforts on tailwaters below dams where current concentrates baitfish.

What do Blue Catfish eat?

Blue catfish are opportunistic omnivorous predators that consume a diverse diet including fish (especially shad), insects, crawfish, crabs, freshwater mussels, clams, worms, and frogs. They're particularly noted for eating Asian carp and feeding on injured baitfish below dams.

Where do Blue Catfish live in Indiana?
