Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01230 (0.00541 - 0.02797), b=2.99 (2.81 - 3.17), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).
Niveau trophique (Ref. 69278):  3.2   ±0.40 se; based on food items.
Generation time: 2.4 ( 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=4.6).
Fishing Vulnerability (Ref. 59153):  Low to moderate vulnerability (27 of 100).
Catégorie de prix (Ref. 80766):   Unknown.
