Estimates based on models

Fylogenetische diversiteitsindex (Ref. 82804):  PD50 = 0.7500   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.02455 (0.01070 - 0.05632), b=3.00 (2.80 - 3.20), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trofisch niveau (Ref. 69278):  2.0   ±0.00 se; based on food items.
Weerstandsvermogen (Ref. 120179):  Hoog, minimale populatieverdubbelingstijd minder dan 15 maanden (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Moderate vulnerability (39 of 100).
Prijsklasse (Ref. 80766):   Unknown.
Nutrients (Ref. 124155):  Calcium = 76.1 [25.1, 186.6] mg/100g; Iron = 1.76 [0.87, 4.38] mg/100g; Protein = 18.7 [16.6, 21.0] %; Omega3 = 0.522 [0.209, 1.343] g/100g; Selenium = 42.4 [16.5, 105.7] μg/100g; VitaminA = 8.7 [2.3, 31.5] μg/100g; Zinc = 1.13 [0.75, 1.83] mg/100g (wet weight);
