Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = 0.7510   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00832 (0.00318 - 0.02175), b=2.99 (2.77 - 3.21), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Niveau trophique (Ref. 69278):  3.2   ±0.45 se; based on food items.
Generation time: 3.8 ( na - na) years. Estimated as median ln(3)/K based on 1 growth studies.
Résilience (Ref. 120179):  Milieu, temps minimum de doublement de population : 1,4 à 4,4 années (K=0.29).
Fishing Vulnerability (Ref. 59153):  Moderate vulnerability (38 of 100).
Catégorie de prix (Ref. 80766):   Unknown.
