Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5312 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00776 (0.00516 - 0.01167), b=3.14 (3.02 - 3.26), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref.
93245).
Niveau trophique (Ref.
69278): 3.3 ±0.4 se; based on size and trophs of closest relatives
Generation time: 11.0 ( na - na) years. Estimated as median ln(3)/K based on 1
growth studies.
Résilience (Ref.
120179): Très faible, temps minimum de doublement de population supérieur à 14 ans (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
59153): High vulnerability (65 of 100).
