Mature females may spawn for the first time from around 6-8 years of age (Ref. 71843).

Oceanodromous. Migrating within oceans typically between spawning and different feeding areas, as tunas do. Migrations should be cyclical and predictable and cover more than 100 km.

Dorsal spines (total): 4 - 7; Dorsal soft rays (total): 32 - 36; Analsoft rays: 26 - 30

The sexually immature members of the population stay in lesser depths, mainly in the shallow fjord bays. Yearlings feed mainly on mesozooplankton in the near surface zone (5-15 m). Immature and mature fish are benthic but stay in shallower depths (10-20 m). Sexually mature fish move out of the fjord to stay in the shelf zone. Spawn once a year (Ref. 89316). Maximum life span for males is 12 years (Ref. 28106).
