Environment / Climate / Range
Marine; brackish; benthopelagic; oceanodromous (Ref. 35388); depth range 5 - 400 m (Ref. 9563), usually 50 - 150 m (Ref. 4968). Temperate, preferred 23°C (Ref. 107945); 75°N - 49°S, 17°W - 177°E (Ref. 54935)
Length at first maturity / Size / Weight / Age
Maturity: Lm 36.2, range 29 - 35 cm
Max length : 90.0 cm TL male/unsexed; (Ref. 6953); common length : 40.0 cm TL male/unsexed; (Ref. 6953); max. published weight: 8.0 kg (Ref. 35388); max. reported age: 12 years (Ref. 5377)
Worldwide in distribution. Eastern Atlantic: Norway to South Africa, also the Mediterranean and Black Sea. Western Pacific: Japan, Korea, Australia and New Zealand. Also known from the Indian Ocean.
Found in areas close to the sea bed (Ref. 6390). Generally solitary. Feeds mainly on schooling bony fishes, occasionally on cephalopods and crustaceans (Ref. 27121). Reproduction takes place at the end of winter and at the start of spring in the northeastern Atlantic, earlier in the Mediterranean. Eggs are pelagic, maturity reached at 4 years (Ref. 36731). Sold fresh (Ref. 9563) and frozen (Ref. 9988). Can be steamed, fried, broiled, boiled, microwaved and baked (Ref. 9988). The flesh is excellent but is utilized little in West Africa (Ref. 5377).
No studies of their reproductive development or early life history have been undertaken in Australia (Ref. 6390). Pelagic eggs (Ref. 35388).

Estimates of some properties based on models
Phylogenetic diversity index (Ref. 82805
= 0.7656 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01660 (0.01284 - 0.02145), b=2.92 (2.84 - 3.00), based on LWR estimates for this species (Ref. 93245
Trophic Level (Ref. 69278
): 4.5 ±0.8 se; Based on diet studies.
Resilience (Ref. 69278
): Low, minimum population doubling time 4.5 - 14 years (K=0.15; tm=3-4; tmax=12).
Vulnerability (Ref. 59153
