Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5664   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00355 (0.00144 - 0.00875), b=3.07 (2.85 - 3.29), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Niveau trophique (Ref. 69278):  4.2   ±0.6 se; based on size and trophs of closest relatives
Résilience (Ref. 120179):  Très faible, temps minimum de doublement de population supérieur à 14 ans (Fec=2).
Fishing Vulnerability (Ref. 59153):  High vulnerability (58 of 100).
