Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.7500 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00851 (0.00459 - 0.01580), b=3.10 (2.92 - 3.28), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref.
93245).
Generation time: 3.7 ( na - na) years. Estimated as median ln(3)/K based on 1
growth studies.
Résilience (Ref.
120179): Faible, temps minimum de doublement de population : 4,5 à 14 années (K=0.124; Tmax=10).
Fishing Vulnerability (Ref.
59153): Moderate vulnerability (39 of 100).
