Estimates based on models

Fylogenetische diversiteitsindex (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01905 (0.01055 - 0.03442), b=3.08 (2.93 - 3.23), in cm Total Length, based on LWR estimates for this species & Genus-body shape (Ref. 93245).
Trofisch niveau (Ref. 69278):  2.7   ±0.33 se; based on food items.
Weerstandsvermogen (Ref. 120179):  Hoog, minimale populatieverdubbelingstijd minder dan 15 maanden (K=0.7).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (22 of 100).
