Estimates based on models

Preferred temperature (Ref. 123201): 6.9 - 14.1, mean 10.3 °C (based on 75 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5039   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00661 (0.00222 - 0.01969), b=2.95 (2.71 - 3.19), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Niveau trophique (Ref. 69278):  3.8   ±0.5 se; based on size and trophs of closest relatives
Résilience (Ref. 120179):  Faible, temps minimum de doublement de population : 4,5 à 14 années (Fec assumed to be <100).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (22 of 100).
