Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01660 (0.01353 - 0.02036), b=2.96 (2.93 - 2.99), in cm total length, based on LWR estimates for this species (Ref.
93245).
Résilience (Ref.
120179): Faible, temps minimum de doublement de population : 4,5 à 14 années (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
59153): Moderate vulnerability (40 of 100).
