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=0.01905 (0.01055 - 0.03442), b=3.08 (2.93 - 3.23), in cm total length, based on LWR estimates for this species & Genus-body shape (Ref. 93245).
Niveau trophique (Ref. 69278):  2.7   ±0.33 se; based on food items.
Generation time: 1.5 ( na - na) years. Estimated as median ln(3)/K based on 1 growth studies.
Résilience (Ref. 120179):  Haut, temps minimum de doublement de population inférieur à 15 mois (K=0.7).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (22 of 100).
