Estimates based on models

Preferred temperature (Ref. 123201): 16.2 - 27.9, mean 25.5 °C (based on 265 cells).
Fylogenetische diversiteitsindex (Ref. 82804):  PD50 = 0.5039   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00295 (0.00151 - 0.00578), b=3.13 (2.96 - 3.30), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trofisch niveau (Ref. 69278):  3.6   ±0.5 se; based on size and trophs of closest relatives
Weerstandsvermogen (Ref. 120179):  laag, minimale populatieverdubbelingstijd 4,5-14 jaar (Fec assumed to be <100).
Fishing Vulnerability (Ref. 59153):  High vulnerability (60 of 100).
