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=0.01380 (0.00775 - 0.02460), b=3.05 (2.89 - 3.21), in cm total length, based on LWR estimates for this species & Genus-body shape (Ref.
93245).
Niveau trophique (Ref.
69278): 3.0 ±0.40 se; based on food items.
Generation time: 1.9 ( na - na) years. Estimated as median ln(3)/K based on 1
growth studies.
Résilience (Ref.
120179): Haut, temps minimum de doublement de population inférieur à 15 mois (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
59153): Moderate vulnerability (43 of 100).
