Estimates based on models

Preferred temperature (Ref. 123201): 12.9 - 18.9, mean 14.6 °C (based on 38 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00282 (0.00133 - 0.00596), b=3.25 (3.08 - 3.42), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).
Niveau trophique (Ref. 69278):  3.8   ±0.6 se; based on size and trophs of closest relatives
Résilience (Ref. 120179):  Faible, temps minimum de doublement de population : 4,5 à 14 années (Preliminary low fecundity).
Fishing Vulnerability (Ref. 59153):  Moderate to high vulnerability (46 of 100).
