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=0.01950 (0.01140 - 0.03336), b=2.92 (2.78 - 3.06), in cm total length, based on LWR estimates for this species & Genus-body shape (Ref.
93245).
Niveau trophique (Ref.
69278): 2.4 ±0.1 se; based on size and trophs of closest relatives
Generation time: 0.8 ( 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): Low vulnerability (10 of 100).
