Estimates based on models

Fylogenetische diversiteitsindex (Ref. 82804):  PD50 = 0.5010   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01047 (0.00673 - 0.01628), b=3.21 (3.08 - 3.34), in cm total length, based on LWR estimates for this species & Genus-body shape (Ref. 93245).
Trofisch niveau (Ref. 69278):  2.5   ±0.1 se; based on size and trophs of closest relatives
Weerstandsvermogen (Ref. 120179):  laag, minimale populatieverdubbelingstijd 4,5-14 jaar (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Moderate to high vulnerability (47 of 100).
Nutrients (Ref. 124155):  Calcium = 77.1 [22.2, 187.0] mg/100g; Iron = 1.12 [0.49, 2.53] mg/100g; Protein = 17.6 [15.5, 20.0] %; Omega3 = 0.169 [0.060, 0.464] g/100g; Selenium = 50.1 [18.9, 121.7] μg/100g; VitaminA = 38.1 [9.7, 118.7] μg/100g; Zinc = 2.22 [1.48, 3.31] mg/100g (wet weight);
