Estimates based on models

Preferred temperature (Ref. 123201): -0.1 - 4.5, mean 1.7 °C (based on 770 cells).
Fylogenetische diversiteitsindex (Ref. 82804):  PD50 = 0.5010   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00676 (0.00300 - 0.01523), b=3.17 (2.98 - 3.36), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trofisch niveau (Ref. 69278):  3.3   ±0.2 se; based on diet studies.
Generation time: 1.5 ( na - na) years. Estimated as median ln(3)/K based on 1 growth studies.
Weerstandsvermogen (Ref. 120179):  Hoog, minimale populatieverdubbelingstijd minder dan 15 maanden (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (21 of 100).
