Estimates based on models

Preferred temperature (Ref. 123201 ): -1.8 - 0.5, mean -1.1 °C (based on 348 cells). Phylogenetic diversity index (Ref. 82804 ):  PD 50 = 0.5005   [Uniqueness, from 0.5 = low to 2.0 = high]. Bayesian length-weight: a=0.00427 (0.00275 - 0.00661), b=3.29 (3.16 - 3.42), in cm total length, based on LWR estimates for this species & Genus-body shape (Ref. 93245 ). Trophic level (Ref. 69278 ):  3.4   ±0.54 se; based on food items. Resilience (Ref. 120179 ):  Medium, minimum population doubling time 1.4 - 4.4 years (K=0.22-0.23; Fec = 5,851-12,000). Fishing Vulnerability (Ref. 59153 ):  High vulnerability (55 of 100). Climate Vulnerability (Ref. 125649 ):  High vulnerability (57 of 100). Nutrients (Ref. 124155 ):  Calcium = 22.8 [13.3, 57.4] mg/100g; Iron = 0.459 [0.186, 0.931] mg/100g; Protein = 17.1 [16.1, 18.2] %; Omega3 = 0.352 [0.194, 0.626] g/100g; Selenium = 15.5 [6.3, 37.8] μg/100g; VitaminA = 23 [5, 116] μg/100g; Zinc = 0.487 [0.313, 0.759] mg/100g (wet weight); based on nutrient studies.
