Écologie
marin; saumâtre benthopélagique; océanodrome (Ref. 51243); profondeur 10 - 200 m (Ref. 1371), usually 30 - 100 m (Ref. 1371). Temperate; 72°N - 35°N, 27°W - 42°E
Northeast Atlantic: southeastern Barents Sea and Iceland to Portugal, also in the Black Sea, Aegean Sea, Adriatic Sea and adjacent areas. Rare in the northwestern Mediterranean.
Longueur à la première maturité / Taille / Poids / Âge
Maturité: Lm 28.2, range 28 - 30 cm
Max length : 91.5 cm TL mâle / non sexé; (Ref. 106276); common length : 23.5 cm TL mâle / non sexé; (Ref. 1371); poids max. publié: 3.1 kg (Ref. 40637); âge max. reporté: 20 années (Ref. 35388)
Épines dorsales (Total) : 0; Rayons mous dorsaux (Total) : 30 - 40; Rayons mous anaux: 30 - 35. Body elongate; head small. Chin barbel small or absent. Lateral-line canals on head with pores. Color is variable; yellowish-brown, dark blue or green, sides yellowish grey, white and silvery on belly; often with a small dark blotch at the upper base of the pectoral fin.
Body shape (shape guide): fusiform / normal; Cross section: circular.
More commonly found from 30 to 100 m, mainly on mud and gravel bottoms, but also on sand and rock. Feed on shrimps, crabs, mollusks, small fish, polychaetes and cephalopods. Migrate to the open sea only after the first year of life. Eggs are pelagic. Larvae and juveniles are associated with jellyfish. Upon maturity, small chin barbel characteristic of juveniles disappear (Ref. 53061). Spawn in batches (Ref. 51846). Utilized fresh, dried or salted, smoked and frozen; eaten steamed, broiled and baked (Ref. 9988).
Oviparous, sexes are separate (Ref. 205).
