Estimates based on models

Preferred temperature (Ref. 123201): 9.7 - 21.9, mean 18.4 °C (based on 144 cells).
Fylogenetische diversiteitsindex (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00282 (0.00133 - 0.00596), b=3.25 (3.08 - 3.42), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).
Trofisch niveau (Ref. 69278):  3.8   ±0.6 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):  Moderate to high vulnerability (50 of 100).
