Environment / Climate / Range
Marine; benthopelagic; non-migratory; depth range 1 - 440 m (Ref. 57178), usually 15 - 200 m. Temperate; 66°N - 28°N, 13°W - 36°E
Length at first maturity / Size / Weight / Age
Maturity: Lm 13.4, range 10 - 26 cm
Max length : 40.0 cm TL male/unsexed; (Ref. 1371); common length : 20.0 cm TL male/unsexed; (Ref. 4645); max. reported age: 5 years (Ref. 72488)
spines: 0. Chin barbel well developed. Body brownish yellow dorsally, becoming paler ventrally; a dark blotch is at the base of the pectoral fin.
Eastern Atlantic: Trondheim Fjord and the Faeroe Islands to Portugal and along the Atlantic coast of Morocco; also in the Mediterranean.
Occurs mostly from 15 to 200 m in the Atlantic and to 120 in the Mediterranean on muddy or sandy bottoms. Feeds on crustaceans, small fish, and polychaetes (Ref. 1371). Used in the production of fish meal, and in southern Europe as a human food (Ref. 35388).
