Estimates based on models

Fylogenetische diversiteitsindex (Ref. 82804):  PD50 = 0.7500   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01413 (0.00793 - 0.02517), b=2.96 (2.81 - 3.11), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).
Trofisch niveau (Ref. 69278):  3.2   ±0.44 se; based on food items.
Generation time: 2.1 ( na - na) years. Estimated as median ln(3)/K based on 1 growth studies.
Weerstandsvermogen (Ref. 120179):  Hoog, minimale populatieverdubbelingstijd minder dan 15 maanden (K=0.5).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (25 of 100).
Prijsklasse (Ref. 80766):   Unknown.
