(Cods and haddocks)
Etymology: Trisopterus: Greek, tris = thrice + Greek, pteron = wing, fin (Ref. 45335). More on author: Linnaeus.
The species has been long thought to be present in the Mediteranean in sympatry with Trisopterus capelanus, sometimes both as subspecies. See Delling et al. (2011: Ref. 90172) for the latest revision of the genus.
Environment: milieu / climate zone / depth range / distribution range
; marino bentopelágico; no migratorio; rango de profundidad 1 - 440 m (Ref. 57178), usually 15 - 200 m (Ref. ). Temperate; 0°C - ; 66°N - 28°N, 13°W - 36°E
Northeastern Atlantic: Trondheim Fjord and the Faeroe Islands to Portugal and along the Atlantic coast of Morocco (Ref. 1371). Not present in the Mediterranean (Ref. 90172).
Length at first maturity / Tamaño / Peso / Age
Maturity: Lm 13.4, range 10 - 26 cm
Max length : 40.0 cm TL macho / no sexado; (Ref. 1371); common length : 20.0 cm TL macho / no sexado; (Ref. 4645); edad máxima reportada: 5 años (Ref. 72488)
Espinas dorsales (total): 0; Espinas anales 0. Chin barbel well developed. Body brownish yellow dorsally, becoming paler ventrally; a dark blotch is at the base of the pectoral fin.
Occurs mostly from 15 to 200 m in the Atlantic 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).
Oviparous, sexes are separate (Ref. 205).
