Estimates based on models

Preferred temperature (Ref. 123201): 5.2 - 7.4, mean 6 °C (based on 99 cells).
Fylogenetische diversiteitsindex (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00355 (0.00175 - 0.00721), b=3.08 (2.90 - 3.26), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trofisch niveau (Ref. 69278):  3.9   ±0.4 se; based on size and trophs of closest relatives
Weerstandsvermogen (Ref. 120179):  Zeer laag, minimale populatieverdubbelingstijd meer dan 14 jaar (Fec assumed to be <10).
Fishing Vulnerability (Ref. 59153):  Moderate vulnerability (44 of 100).
Prijsklasse (Ref. 80766):   Low.
