Estimates based on models
Phylogenetic diversity index (Referencia
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01380 (0.00859 - 0.02217), b=2.92 (2.79 - 3.05), in cm total length, based on LWR estimates for this species & Genus-body shape (Ref.
93245).
Nivel trófico (Referencia
69278): 2.8 ±0.3 se; based on size and trophs of closest relatives
Generation time: 1.7 ( na - na) years. Estimated as median ln(3)/K based on 1
growth studies.
Resiliencia (Referencia
120179): Alto, población duplicada en un tiempo mínimo inferior a 15 meses (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
59153): Low vulnerability (22 of 100).
