Also known as
- Blue Cat US
- Mississippi White Catfish US
- High-fin Blue US
- Hump-back Blue US
Identification
A massive cylindrical North American catfish with a robust muscular build engineered for brute pulling power in heavy current — almost never jumps, just dives. Females grow larger than males.
- Slate-blue to pale blue-grey back and sides fading to a white belly
- No spots or markings — uniformly coloured
- Deeply forked tail with long pointed lobes
- Smooth scaleless skin with a protective mucus coating and prominent barbels around the mouth
Where it holds
- Rivers
- Lakes
Behaviour
Opportunistic bottom-oriented predator and scavenger; adults shift toward live fish as they grow, with crayfish and cut bait taken readily throughout life. Smell and chemical-sensing barbels locate food in turbid water, so strike rates in muddy water rival clear. Nocturnal with strong daytime feeding in coloured water. Feeding climbs above 21°C (70°F), peaks 24-29°C (75-84°F). Concentrates in deep channels, below dams, and scoured holes where current funnels prey.
Diet: Shad, Herring, Bluegill, Crayfish, Cut Bait
How it's caught
Line Fishing
Bottom Fishing
Anchor or drift over deep holes, main river channels, and tailwater below dams with a slip-sinker or three-way rig. Fresh cut shad, skipjack, and herring chunks are the proven producers for size; large live baits draw the biggest specimens. Use heavy sinkers to hold bottom in current and pile on pressure immediately — fish dive straight for snags.
Drift Fishing
Drift cut shad or skipjack on a slip-sinker rig across deep flats, ledges, and channel edges where fish roam at night. Controlled drift speed with electric motor keeps the bait in the strike zone; subtle ticks precede committed runs. Outproduces anchoring when fish are spread out.
Float Fishing
Slip-float a live shad or fresh cut bait 1-3m off the bottom around riprap, bridge pilings, and current breaks where fish hold suspended off the bottom. Particularly effective when fish are reluctant to move far in cold or pressured water.
