Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 4 - 7; Dorsal soft rays (total): 34 - 38; Anal soft rays: 30 - 35. Yellowish with dark spots, irregular crossbars. Dorsal and caudal with series of spots sometimes (Ref. 11892).

Biology     Glossary (e.g. epibenthic)

A cryopelagic species associated with the underside of ice. An anti-freezing substance enable Individuals to tolerate sub-zero temperature (Ref. 33215). Adults feed on copepods and krill (Ref. 5179). Sexually mature individuals spawn once a year (Ref. 89319). Larval pelagic phase is long (Ref. 89319).

Estimates based on models

Preferred temperature (Ref. 123201): -1.8 - -1, mean -1.7 °C (based on 1248 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.7500   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00617 (0.00322 - 0.01181), b=3.21 (3.04 - 3.38), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.2   ±0.34 se; based on food items.
Generation time: 7.8 ( na - na) years. Estimated as median ln(3)/K based on 1 growth studies.
Resilience (Ref. 120179):  Medium, minimum population doubling time 1.4 - 4.4 years (Fec = 1,500-3,000).
Fishing Vulnerability (Ref. 59153):  Moderate to high vulnerability (52 of 100).
Nutrients (Ref. 124155):  Calcium = 30.6 [15.7, 69.2] mg/100g; Iron = 0.576 [0.269, 1.185] mg/100g; Protein = 17.1 [15.6, 18.7] %; Omega3 = 0.406 [0.217, 0.752] g/100g; Selenium = 11.5 [4.2, 25.6] μg/100g; VitaminA = 28.7 [6.0, 141.0] μg/100g; Zinc = 0.58 [0.38, 0.90] mg/100g (wet weight); based on nutrient studies.
