Species Information

Wolffish are ferocious looking creatures and are notable fighters. This bottom-dwelling, solitary, cold water fish eat hard-shelled invertebrates such as clams, echinoderms and crustaceans, which they crush with strong canine and molar teeth. Wolffish are known to reach lengths of around seven feet or longer but often average around three feet in length. In European countries this fish is often commonly called the catfish and is highly popular as a food fish. During most of the year the wolffish is not a migratory fish preferring to spend its time along deep waters along the bottom. But when spring arrives it will make small migrations inland in preparation for the spawning season.
