Estimates based on models

Fylogenetische diversiteitsindex (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00263 (0.00118 - 0.00585), b=3.26 (3.09 - 3.43), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).
Trofisch niveau (Ref. 69278):  3.5   ±0.37 se; based on food items.
Weerstandsvermogen (Ref. 120179):  laag, minimale populatieverdubbelingstijd 4,5-14 jaar (Fec assumed to be <100).
Fishing Vulnerability (Ref. 59153):  Moderate to high vulnerability (54 of 100).
Prijsklasse (Ref. 80766):   Medium.
