Short description

Dorsal spines (total): 4 - 7; Dorsal soft rays (total): 32-36; Anal soft 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).

IUCN Red List Status (Ref. 115185)
