Estimates based on models

Preferred temperature (Ref. 123201): -1.4 - 1.3, mean 0.5 °C (based on 43 cells).

Fylogenetische diversiteitsindex (Ref. 82804): PD₅₀ = 0.6250 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00132 (0.00102 - 0.00170), b=3.51 (3.44 - 3.58), in cm total length, based on LWR estimates for this species (Ref. 93245).

Trofisch niveau (Ref. 69278): 3.9 ±0.62 se; based on food items.

Generation time: 5.8 ( na - na) years. Estimated as median ln(3)/K based on 1 growth studies.

Weerstandsvermogen (Ref. 120179): Gemiddeld, minimale populatieverdubbelingstijd 1,4-4,4 jaar (Assuming tm<5).

Fishing Vulnerability (Ref. 59153): Moderate to high vulnerability (51 of 100).

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

Prijsklasse (Ref. 80766): High.

Nutrients (Ref. 124155): Calcium = 18.7 [10.4, 38.9] mg/100g; Iron = 0.338 [0.153, 0.672] mg/100g; Protein = 16.8 [15.1, 18.5] %; Omega3 = 0.249 [0.120, 0.520] g/100g; Selenium = 22.7 [8.8, 55.3] μg/100g; VitaminA = 23.8 [5.3, 113.0] μg/100g; Zinc = 0.391 [0.259, 0.597] mg/100g (wet weight);
