Flathead Catfish
Pylodictis olivaris
Flathead Catfish are large, nocturnal ambush predators of big rivers, reservoirs, and deep holes in North American freshwater systems. They are prized by anglers for size and table quality, but they readily eat live fish and other sizable prey.

Identification points
- Broad, flattened head with a shovel-like snout
- Lower jaw noticeably protrudes beyond the upper jaw
- Plain mottled yellow-brown to olive body with a light belly and no obvious forked tail
Habitat
Deep pools, undercut banks, logjams, bridge pilings, riprap, and channel edges in large rivers and reservoirs; often lies tight to heavy cover during the day.
Bait notes
Best on live bait such as sunfish, bullheads, shad, bluegill, or skipjack herring where legal; cut bait can work but usually trails live bait for trophy fish. Large chunks or whole bait fish matched to local forage are effective.
Behavior
Mostly nocturnal and sedentary by day, then hunts at night using smell and lateral-line sensing. Feeds primarily on live fish, especially sunfish, shad, and other available prey, and can be territorial around cover.
Caution
Sharp dorsal and pectoral spines can puncture hands, and large fish are very strong to land. Check local regulations on live baitfish use and invasive species transport; consume only from waters with safe fish-consumption advisories.
Fishing notes
Fish slow and close to cover with heavy tackle, strong hooks, and abrasion-resistant leader. Set baits on bottom near current seams, deep holes, and structure; most bites come after dark or at dusk/dawn. Be ready for long, powerful runs.
