Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01000 (0.00244 - 0.04107), b=3.04 (2.81 - 3.27), in cm Total Length, based on all LWR estimates for this body shape (Ref. 93245).
Niveau trophique (Ref. 69278):  3.2   ±0.4 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).
