Estimates based on models

Fylogenetische diversiteitsindex (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00355 (0.00175 - 0.00721), b=3.08 (2.90 - 3.26), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trofisch niveau (Ref. 69278):  3.9   ±0.6 se; based on size and trophs of closest relatives
Weerstandsvermogen (Ref. 120179):  Zeer laag, minimale populatieverdubbelingstijd meer dan 14 jaar (Fec assumed to be <10).
Fishing Vulnerability (Ref. 59153):  Moderate vulnerability (42 of 100). 🛈
Nutrients (Ref. 124155):  Calcium = 68 [11, 679] mg/100g; Iron = 0.416 [0.082, 2.133] mg/100g; Protein = 18.2 [15.6, 20.9] %; Omega3 = 0.217 [0.047, 0.913] g/100g; Selenium = 3.5 [0.6, 22.8] μg/100g; VitaminA = 338 [26, 4,063] μg/100g; Zinc = 1.53 [0.54, 4.90] mg/100g (wet weight);
