Estimates based on models

Preferred temperature (Ref. 115969): 6.2 - 7.9, mean 7 °C (based on 8 cells).
Phylogenetic diversity index (Ref. 82805):  PD50 = 0.7500   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00102 (0.00046 - 0.00225), b=3.06 (2.88 - 3.24), in cm total length, based on all LWR estimates for this BS (Ref. 93245).
Trophic level (Ref. 69278):  4.5   ±0.7 se; based on diet studies.
Resilience (Ref. 120179):  Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Moderate to high vulnerability (45 of 100) .
Climate Vulnerability (Ref. 125649):  High to very high vulnerability (66 of 100) .
Nutrients (Ref. 124155):  Calcium = 29 [14, 60] mg/100g ; Iron = 0.363 [0.201, 0.706] mg/100g ; Protein = 17.3 [14.9, 19.5] % ; Omega3 = 0.284 [0.151, 0.514] g/100g ; Selenium = 24.4 [10.5, 50.6] μg/100g ; VitaminA = 15.3 [3.9, 55.5] μg/100g ; Zinc = 0.36 [0.25, 0.53] mg/100g (wet weight);
