Estimates based on models

Preferred temperature (Ref. 123201): 5.6 - 9, mean 6.9 °C (based on 52 cells).
Phylogenetic diversity index (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).
Niveau trophique (Ref. 69278):  3.6   ±0.0 se; based on diet studies.
Résilience (Ref. 120179):  Très faible, temps minimum de doublement de population supérieur à 14 ans (Fec assumed to be <10).
Fishing Vulnerability (Ref. 59153):  Moderate to high vulnerability (48 of 100).
