Max length : 140 cm TL самец/пол неопределен; (Ref. 6605); common length : 50.0 cm TL самец/пол неопределен; (Ref. 1371)
колючие лучи спинного плавника (общее число) : 1; членистые (мягкие) лучи спинного плавника (общее число) : 47 - 54; колючие лучи анального плавника: 0; членистые (мягкие) лучи анального плавника: 37 - 41. Light brown above, silvery to white below (Ref. 6605).
Found on the continental shelf and slope to depths over 1,000 m (Ref. 27121). Juveniles (to about 64 cm) feed on small crustaceans and small deep-sea fishes such as lanternfishes, whereas larger individuals feed chiefly on small hakes and jack mackerel (Ref. 1371); cannibalism is common (Ref. 27121). Migrates southward in the spring and northward in autumn (Ref. 1371). Breeds throughout the year, peaks of reproductive activity in August and September (Ref. 36731). Marketed smoked, frozen, and fresh on ice; eaten steamed, fried and baked (Ref. 9988).

Estimates based on models
Preferred temperature (Ref.
123201): 7.7 - 14.4, mean 10.2 °C (based on 78 cells).
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00513 (0.00339 - 0.00775), b=3.11 (2.98 - 3.24), in cm total length, based on LWR estimates for this species & Genus-body shape (Ref.
93245).
Trophic level (Ref.
69278): 3.9 ±0.65 se; based on food items.
Generation time: 9.2 (7.9 - 12.1) years. Estimated as median ln(3)/K based on 21
growth studies.
устойчивость к внешним воздействиям (Ref.
120179): низкий, минимальное время удвоения популяции 4.5-14 лет (K=0.07-0.13).
