Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.6250 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.03311 (0.02090 - 0.05247), b=3.01 (2.87 - 3.15), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref.
93245).
Résilience (Ref.
120179): Haut, temps minimum de doublement de population inférieur à 15 mois (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
59153): Low to moderate vulnerability (31 of 100).
