Length at first maturity / Size / Weight / Age

Maturity: L m 44.9   range ? - ? cm
Max length : 72.0 cm TL male/unsexed; (Ref. 4883 ); common length : 50.0 cm TL male/unsexed; (Ref. 2805 ); max. published weight: 3.7 kg (Ref. 4883 )

Biology     Glossary (e.g. epibenthic)

Adults feed mostly on fish and krill. Synchronous spawner (Ref. 50743 ). Larvae have a long pelagic phase (Ref. 71843 ). Utilized as a food fish (Ref. 4931 ).

Life cycle and mating behavior Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae

There is only one generation of oocytes in the ovaries indicative of determinate fecundity (Ref. 50743 ). Mature females may spawn for the first time from around 6-8 years of age (Ref. 71843 ).

Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805 ):  PD 50 = 1.0000   [Uniqueness, from 0.5 = low to 2.0 = high]. Bayesian length-weight: a=0.00091 (0.00074 - 0.00113), b=3.48 (3.42 - 3.54), in cm Total Length, based on LWR estimates for this species (Ref. 93245 ). Trophic Level (Ref. 69278 ):  3.4   ±0.2 se; Based on diet studies. Resilience (Ref. 69278 ):  Medium, minimum population doubling time 1.4 - 4.4 years (K=0.17-0.24; Fec = 7,358). Vulnerability (Ref. 59153 ):  High to very high vulnerability (68 of 100) . Price category (Ref. 80766 ):   High .
