Estimates based on models

Fylogenetische diversiteitsindex (Ref. 82804):  PD50 = 0.5039   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.02455 (0.01209 - 0.04986), b=2.96 (2.79 - 3.13), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).
Trofisch niveau (Ref. 69278):  4.1   ±0.60 se; based on food items.
Weerstandsvermogen (Ref. 120179):  Gemiddeld, minimale populatieverdubbelingstijd 1,4-4,4 jaar (K=0.18-0.28).
Fishing Vulnerability (Ref. 59153):  High vulnerability (57 of 100).
Prijsklasse (Ref. 80766):   Very high.
