Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5039 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01288 (0.00694 - 0.02391), b=2.94 (2.79 - 3.09), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref.

Résilience (Ref.
120179): Faible, temps minimum de doublement de population : 4,5 à 14 années (Fec = 15).
Fishing Vulnerability (Ref.
