Estimates based on models

Preferred temperature (Ref. 123201): -1.1 - 2.9, mean 1.5 °C (based on 50 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.7500 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00117 (0.00100 - 0.00138), b=3.47 (3.42 - 3.52), in cm total length, based on LWR estimates for this species (Ref. 93245).

Trophic level (Ref. 69278): 3.2 ±0.2 se; based on diet studies.

Widerstandsfähigkeit (Ref. 120179): mittel, Verdopplung der Population dauert 1,4 - 4,4 Jahre. (K=0.13-0.39; tmax=13; tm=4; Fec=3,094).

Prior r = 0.39, 95% CL = 0.24 - 0.64, Based on 2 stock assessments.

Fishing Vulnerability (Ref. 59153): Moderate vulnerability (35 of 100).

Climate Vulnerability (Ref. 125649): High to very high vulnerability (68 of 100).

Preiskategorie (Ref. 80766): Very high.

Nutrients (Ref. 124155): Calcium = 20.5 [11.1, 44.8] mg/100g; Iron = 0.388 [0.165, 0.801] mg/100g; Protein = 16.9 [14.8, 18.9] %; Omega3 = 0.222 [0.107, 0.473] g/100g; Selenium = 25.9 [9.2, 64.1] μg/100g; VitaminA = 13.8 [2.8, 70.5] μg/100g; Zinc = 0.409 [0.265, 0.626] mg/100g (wet weight); based on nutrient studies.
