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=0.01479 (0.01199 - 0.01825), b=3.05 (3.01 - 3.09), in cm total length, based on LWR estimates for this species (Ref.
93245).
Nivel trófico (Ref.
69278): 3.0 ±0.3 se; based on diet studies.
Generation time: 1.3 ( na - na) years. Estimated as median ln(3)/K based on 1
growth studies.
Resiliencia (Ref.
120179): Alto, población duplicada en un tiempo mínimo inferior a 15 meses (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
59153): Low vulnerability (16 of 100).
