Estimates based on models

Fylogenetische diversiteitsindex (Ref. 82804): PD₅₀ = 0.5625 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01514 (0.00769 - 0.02979), b=3.05 (2.89 - 3.21), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).

Trofisch niveau (Ref. 69278): 3.4 ±0.51 se; based on food items.

Weerstandsvermogen (Ref. 120179): laag, minimale populatieverdubbelingstijd 4,5-14 jaar (K=0.06-0.09; tm=4.8-9.7; tmax=50).

Fishing Vulnerability (Ref. 59153): High to very high vulnerability (68 of 100).

Prijsklasse (Ref. 80766): Low.

Nutrients (Ref. 124155): Calcium = 50.9 [26.6, 99.2] mg/100g; Iron = 0.707 [0.383, 1.290] mg/100g; Protein = 17.5 [15.7, 19.3] %; Omega3 = 0.21 [0.13, 0.35] g/100g; Selenium = 83.4 [37.5, 171.5] μg/100g; VitaminA = 21.4 [6.0, 69.9] μg/100g; Zinc = 1.07 [0.72, 1.56] mg/100g (wet weight);
