Estimates based on models

Preferred temperature (Ref. 115969): -1.8 - 0.9, mean -0.9 °C (based on 584 cells).
Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5005   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00479 (0.00320 - 0.00717), b=3.19 (3.07 - 3.31), in cm total length, based on LWR estimates for species & Genus-BS (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.
Resilience (Ref. 120179):  Low, minimum population doubling time 4.5 - 14 years (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Moderate to high vulnerability (47 of 100) .
Climate Vulnerability (Ref. 125649):   (0 of 100) .
Nutrients (Ref. 124155):  Calcium = 36.6 [17.9, 76.4] mg/100g ; Iron = 0.351 [0.197, 0.651] mg/100g ; Protein = 17.2 [16.2, 18.2] % ; Omega3 = 0.379 [0.201, 0.692] g/100g ; Selenium = 14.6 [6.0, 30.9] μg/100g ; VitaminA = 27.6 [6.5, 112.8] μg/100g ; Zinc = 0.62 [0.41, 0.94] mg/100g (wet weight); based on nutrient studies.
