Estimates based on models

Preferred temperature (Ref. 123201): 1.3 - 4.2, mean 2.6 °C (based on 235 cells).
Fylogenetische diversiteitsindex (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00513 (0.00253 - 0.01042), b=3.12 (2.95 - 3.29), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).
Trofisch niveau (Ref. 69278):  4.0   ±0.7 se; based on size and trophs of closest relatives
Generation time: 27.5 ( na - na) years. Estimated as median ln(3)/K based on 1 growth studies.
Weerstandsvermogen (Ref. 120179):  laag, minimale populatieverdubbelingstijd 4,5-14 jaar (Fec assumed to be <100).
Fishing Vulnerability (Ref. 59153):  Very high vulnerability (75 of 100).
