Max length : 200 cm TL macho/indeterminado; (Ref. 1371); common length : 106 cm TL macho/indeterminado; (Ref. 1371); peso máx. publicado: 45.0 kg (Ref. 35388); idade máx. registrada: 25 anos (Ref. 35388)
Espinhos dorsais (total): 0; Raios dorsais (total): 75-83; Raios anais : 58 - 64; Vértebras: 63 - 65. Upper jaw projecting beyond lower one. Color is reddish brown dorsally, grading to white ventrally. The posterior areas of the vertical fins dark with pale margins. The sides distinctly marbled (Ref. 232). Barbel is present in the chin, longer than the diameter of the eye. Black spot in the rear end of the first dorsal fin. Caudal peduncle stout compared to blue ling (Ref. 35388).
Occurs mainly on rocky bottoms in fairly deep water (Ref. 9988). Found more commonly from 100 to 400 m. Feeds on fish (cod, herring, flatfish), lobsters, cephalopods and starfishes. Principal spawning areas are Biscay, slopes west of the British Isles and off the Faeroes and southern Iceland (Ref. 35388). Marketed fresh, dried or salted and frozen; eaten steamed, fried, broiled and baked (Ref. 9988).
Major spawning grounds are located at 200 m depth from the Bay of Biscay to the Gulf of Norway at 100 to 300 m off southern Iceland, and at 50 to 300 m in the Mediterranean Sea. Fecundity may reach 20 to 60 million eggs per female (Ref. 1371).
