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=0.01445 (0.00674 - 0.03099), b=2.99 (2.82 - 3.16), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Niveau trophique (Ref. 69278):  3.5   ±0.37 se; based on food items.
Résilience (Ref. 120179):  Milieu, temps minimum de doublement de population : 1,4 à 4,4 années (Assuming Fec<1000).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
