Description

The blue catfish is a large North American catfish of the family Ictaluridae. The species can reach about 1.6 metres and is one of the largest catfishes of North America; the body is blue-grey with a white belly, with barbels and a deeply forked tail. It inhabits deep water of impoundments and the main channels and backwaters of medium to large rivers, over mud, sand and gravel, and tolerates slightly brackish water. As an omnivore and scavenger it eats fishes, crustaceans, molluscs and plant matter. The pectoral and dorsal spines can give painful puncture wounds. The blue catfish is a prized sport and food fish.
