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=0.01122 (0.00823 - 0.01529), b=3.03 (2.94 - 3.12), in cm total length, based on LWR estimates for this species (Ref. 93245).
Niveau trophique (Ref. 69278):  3.1   ±0.41 se; based on food items.
Generation time: 13.1 ( na - na) years. Estimated as median ln(3)/K based on 2 growth studies.
Résilience (Ref. 120179):  Faible, temps minimum de doublement de population : 4,5 à 14 années (tmax=20).
Fishing Vulnerability (Ref. 59153):  High to very high vulnerability (70 of 100).
