Biology     Glossary (e.g. 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 Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae

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

Estimates based on models

Preferred temperature (Ref. 123201): 0.7 - 4.7, mean 2.1 °C (based on 140 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5078   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00589 (0.00480 - 0.00723), b=3.19 (3.13 - 3.25), in cm total length, based on LWR estimates for this species (Ref. 93245).
Trophic level (Ref. 69278):  3.6   ±0.56 se; based on food items.
Generation time: 8.5 (6.1 - 9.8) years. Estimated as median ln(3)/K based on 17 growth studies.
Resilience (Ref. 120179):  Low, minimum population doubling time 4.5 - 14 years (K=0.10-0.16; tmax=16; Fec=19,000).
