Estimates based on models

Preferred temperature (Ref. 123201): 3.4 - 10.2, mean 6.9 °C (based on 170 cells).

Fylogenetische diversiteitsindex (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00316 (0.00189 - 0.00529), b=3.19 (3.04 - 3.34), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).

Trofisch niveau (Ref. 69278): 3.7 ±0.54 se; based on food items.

Generation time: 13.9 ( na - na) years. Estimated as median ln(3)/K based on 1 growth studies.

Weerstandsvermogen (Ref. 120179): laag, minimale populatieverdubbelingstijd 4,5-14 jaar (K=0.077; tmax=38; Fec = 458 (per batch)).

Fishing Vulnerability (Ref. 59153): High to very high vulnerability (69 of 100).

Climate Vulnerability (Ref. 125649): Moderate to high vulnerability (47 of 100).

Prijsklasse (Ref. 80766): Unknown.

Nutrients (Ref. 124155): Calcium = 15.6 [8.0, 45.5] mg/100g; Iron = 0.408 [0.139, 1.088] mg/100g; Protein = 11.5 [9.6, 14.7] %; Omega3 = 0.351 [0.149, 0.942] g/100g; Selenium = 29.1 [12.3, 69.9] μg/100g; VitaminA = 11.9 [2.5, 59.1] μg/100g; Zinc = 0.334 [0.210, 0.548] mg/100g (wet weight); based on nutrient studies.
