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=0.01175 (0.00476 - 0.02897), b=2.88 (2.66 - 3.10), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Niveau trophique (Ref. 69278):  3.1   ±0.3 se; based on size and trophs of closest relatives
Résilience (Ref. 120179):  Faible, temps minimum de doublement de population : 4,5 à 14 années (Assuming fecundity<100).
Fishing Vulnerability (Ref. 59153):  Low to moderate vulnerability (30 of 100).
