Identifying features

Slate-blue to silvery body with a distinctly humped back behind the head
Long, straight-edged anal fin with 30 or more rays — much longer than a channel cat's
Deeply forked tail; skin smooth and scaleless like all catfish
The giant of North American catfish — 50 lb fish are realistic, 100 lb possible
Look-alike: channel catfish have a shorter, rounded anal fin, deeper fork and (young) black spots

Habits

Roams open water and deep river channels more than other catfish, chasing shad schools
Feeds day and night, moving shallow to hunt on windy banks and flats
Big winter aggregations in deep holes produce the trophy season
Uses its barbels and scent to find cut bait in current and muddy water

How to catch them

Drift fishing with cut shad

Rig: Santee-Cooper drift rig, 7/0-8/0 circle hook, peg float

Bait/lure: Fresh cut gizzard shad chunks

Key tip: Drift flats and channel edges at 0.3-0.6 mph; fresh bait outfishes frozen by a wide margin.

Anchored fishing in current

Rig: Three-way or Carolina rig with 2-5 oz sinker

Bait/lure: Cut shad or whole skipjack heads

Key tip: Anchor above deep holes and wing dikes; give trophy fish time — big bites are slow commits.
