Short description पहचान कुंजी | आकृति विज्ञान | मौरफोमैटरिक्स
Body shape (shape guide): elongated.
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 परिपक्व अवधि | पुनरुत्पत्ति | मछलीऔ का अंडे देना | अंडे | Fecundity | लार्वा
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 based on models
Preferred temperature (Ref. 123201): -1.3 - 1.6, mean 0 °C (based on 42 cells).
Phylogenetic diversity index (Ref. 82804): PD50 = 1.0000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00093 (0.00079 - 0.00110), b=3.48 (3.43 - 3.53), 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.
लौटाव (Ref. 120179): माध्यम, न्यूनतम जनसंख्या दुगनी होने का समय 1.4 - 4.4 वर्ष। (K=0.17-0.24; Fec = 7,358).
Fishing Vulnerability (Ref. 59153): Moderate to high vulnerability (54 of 100).
Climate Vulnerability (Ref. 125649): High to very high vulnerability (75 of 100).
Nutrients (Ref. 124155): Calcium = 24.2 [13.5, 53.3] mg/100g; Iron = 0.45 [0.19, 0.91] mg/100g; Protein = 17.3 [15.2, 19.4] %; Omega3 = 0.23 [0.12, 0.43] g/100g; Selenium = 23.3 [9.2, 53.9] μg/100g; VitaminA = 10.8 [2.2, 52.1] μg/100g; Zinc = 0.364 [0.235, 0.556] mg/100g (wet weight); based on nutrient studies.
