Estimates based on models

Preferred temperature (Ref. 123201): -0.3 - 0.8, mean 0.4 °C (based on 69 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 1.0000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00126 (0.00077 - 0.00207), b=3.47 (3.33 - 3.61), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).
Trophic level (Ref. 69278):  3.8   ±0.57 se; based on food items.
Resilience (Ref. 120179):  Medium, minimum population doubling time 1.4 - 4.4 years (Fec = 15,612).
Fishing Vulnerability (Ref. 59153):  Moderate vulnerability (44 of 100).
Climate Vulnerability (Ref. 125649):  High to very high vulnerability (73 of 100).
Nutrients (Ref. 124155):  Calcium = 24 [14, 53] mg/100g; Iron = 0.441 [0.186, 0.897] mg/100g; Protein = 17.4 [15.7, 19.1] %; Omega3 = 0.273 [0.141, 0.520] g/100g; Selenium = 26.2 [10.5, 58.0] μg/100g; VitaminA = 12.9 [2.8, 61.1] μg/100g; Zinc = 0.342 [0.222, 0.522] mg/100g (wet weight);
