Biologia     Glossario (es. epibenthic)

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).

Life cycle and mating behavior Maturità | Riproduzione | Deposizione | Uova | Fecundity | Larve

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