Estimates based on models

Fylogenetische diversiteitsindex (Ref. 82804):  PD50 = 0.6250   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01820 (0.01133 - 0.02923), b=2.87 (2.73 - 3.01), in cm Total Length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).
Trofisch niveau (Ref. 69278):  3.1   ±0.1 se; based on diet studies.
Weerstandsvermogen (Ref. 120179):  Hoog, minimale populatieverdubbelingstijd minder dan 15 maanden (K=1.20; tm=1).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (12 of 100).
