Estimates based on models

Preferred temperature (Ref. 123201): 14.1 - 20.4, mean 18.9 °C (based on 8 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00724 (0.00276 - 0.01903), b=3.04 (2.81 - 3.27), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.9   ±0.6 se; based on size and trophs of closest relatives
Weerstandsvermogen (Ref. 120179):  laag, minimale populatieverdubbelingstijd 4,5-14 jaar (Preliminary low fecundity).
Fishing Vulnerability (Ref. 59153):  Moderate to high vulnerability (50 of 100).
