Ictalurus furcatus
The giant of American catfish — 100 lb fish exist in many big rivers and reservoirs. Blues are open-water predators that follow shad schools like oversized stripers.
Big fresh bait, big water, and drift or anchor on structure holding shad. Winter is trophy time — blues feed hard in cold water when everything else shuts down.
Guide data is editorial and general — conditions, regulations, and fish behavior vary by water. Photo: Wikipedia — Blue catfish.

The main game — mobility to follow shad schools matters more than any secret spot.
Tailwaters, river bends, and reservoir points near the channel give bank access to big blues, especially at night.
Big rivers (Mississippi, Missouri, Ohio, James, Santee-Cooper system) and large reservoirs across the South and Mid-Atlantic.
Blues have a straight-edged anal fin with 30+ rays and slate-blue color without spots.
Size limits, bag limits, seasons, and gear rules change every year and differ by state (and often by individual water). Always verify with the official source before keeping fish.
