Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5312 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00380 (0.00147 - 0.00981), b=3.11 (2.88 - 3.34), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Niveau trophique (Ref. 69278): 4.0 ±0.3 se; based on diet studies.

Generation time: 1.8 ( 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=0.6).

Fishing Vulnerability (Ref. 59153): Low vulnerability (23 of 100).
