Maturity: Lm ?  range ? - ? cm
Max length : 45.3 cm TL male/unsexed; (Ref. 124149); 49.1 cm TL (female); max. published weight: 404.20 g (Ref. 124149); max. published weight: 404.20 g

Biology     Glossary (e.g. epibenthic)

Specimens larger than 26 cm TL were breeding. Spawning seems to take place in autumn or early winter. Feeds mainly on benthic and benthopelagic organisms such as fishes (Trematomus spp.), the decapod Crangon antarcticus, mysids, gammarid amphipod and polychaete worms (Ref. 5192). Minimum depth from Ref. 58018.

Estimates based on models

Preferred temperature (Ref. 115969): -1.8 - -0.2, mean -1.3 °C (based on 72 cells).
Phylogenetic diversity index (Ref. 82805):  PD50 = 1.0000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00062 (0.00039 - 0.00097), b=3.42 (3.28 - 3.56), in cm total length, based on LWR estimates for species & Subfamily-BS (Ref. 93245).
Trophic level (Ref. 69278):  4.1   ±0.73 se; based on food items.
Resilience (Ref. 120179):  Medium, minimum population doubling time 1.4 - 4.4 years (Fec=3,400-8,500).
