Biologie     Fachlexikon (Englisch) (z.B. epibenthic)

Adults feed on fishes and mysids, Crangon antarcticus and Chorismus antarcticus (Ref. 5192). Spawning from end of summer to early winter and hatching occurs throughout winter. Eggs large, 2.4-3.4 mm in diameter, bright red and benthic (Ref. 5192). Synchronous spawner (Ref. 50743). Larval pelagic phase is long (Ref. 35742).

Life cycle and mating behavior Maturities | Fortpflanzung | Spawnings | Egg(s) | Fecundities | Larven

Oocyte maturation occurs synchronously, thus, spawning is completed in a single occasion (Ref. 50743).

Estimates based on models

Preferred temperature (Ref. 123201): -0.1 - 1.5, mean 0.6 °C (based on 10 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.7500   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00224 (0.00117 - 0.00427), b=3.25 (3.07 - 3.43), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  4.0   ±0.6 se; based on diet studies.
Widerstandsfähigkeit (Ref. 120179):  mittel, Verdopplung der Population dauert 1,4 - 4,4 Jahre. (Fec = 8,585).
Fishing Vulnerability (Ref. 59153):  Moderate to high vulnerability (49 of 100).
Climate Vulnerability (Ref. 125649):  Very high vulnerability (88 of 100).
Nutrients (Ref. 124155):  Calcium = 31 [19, 71] mg/100g; Iron = 0.528 [0.229, 1.047] mg/100g; Protein = 17.6 [16.6, 18.5] %; Omega3 = 0.226 [0.118, 0.429] g/100g; Selenium = 20.6 [8.6, 46.2] μg/100g; VitaminA = 10 [2, 46] μg/100g; Zinc = 0.387 [0.258, 0.581] mg/100g (wet weight);
