Estimates based on models

Preferred temperature (Ref. 123201): -1.8 - 0.9, mean -0.9 °C (based on 584 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5005   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00479 (0.00320 - 0.00715), b=3.19 (3.07 - 3.31), in cm total length, based on LWR estimates for this species & Genus-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.2   ±0.2 se; based on diet studies.
Generation time: 11.0 ( na - na) years. Estimated as median ln(3)/K based on 2 growth studies.
Widerstandsfähigkeit (Ref. 120179):  niedrig, Verdopplung der Population dauert 4,5 - 14 Jahre. (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Moderate to high vulnerability (47 of 100).
Nutrients (Ref. 124155):  Calcium = 39.9 [21.9, 100.2] mg/100g; Iron = 0.484 [0.206, 0.969] mg/100g; Protein = 17 [16, 18] %; Omega3 = 0.44 [0.23, 0.82] g/100g; Selenium = 13.6 [5.4, 30.8] μg/100g; VitaminA = 23.9 [5.1, 116.7] μg/100g; Zinc = 0.653 [0.422, 1.002] mg/100g (wet weight); based on nutrient studies.
