A widespread, whiskered scavenger of North American rivers and lakes, the most-farmed freshwater fish in the United States.
Where it lives
Channel catfish are found across the central United States and southern Canada in large rivers, reservoirs, and lakes. They prefer slow to moderate current with sand, gravel, or rubble bottoms and deeper holes for daytime refuge. Tolerant of warm, low-oxygen water.
How to recognise it
A slender, slate-blue to olive body with a deeply forked tail and scattered dark spots — though spots fade in larger adults. Eight long barbels surround the mouth: two on the snout, two on the chin, and four on the lower jaw. The pectoral and dorsal fins bear stout, sometimes mildly venomous spines.
Diet & behavior
Nocturnal omnivores that locate food largely by smell and taste, channels eat almost anything: live fish, dead carrion, crayfish, plant matter, even fruit. Spawning happens in early summer in dark cavities — undercut banks, hollow logs, or muskrat burrows — where males guard the eggs.
Fisheries & Conservation
Globally Least Concern. The species underpins a vast pond-aquaculture industry across the American South, producing the bulk of farmed freshwater fish for U.S. consumption.
