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=0.01318 (0.01108 - 0.01568), b=3.07 (3.03 - 3.11), in cm total length, based on LWR estimates for this species (Ref.
93245).
Nível Trófico (Ref.
69278): 3.0 ±0.3 se; based on diet studies.
Generation time: 2.0 ( na - na) years. Estimated as median ln(3)/K based on 2
growth studies.
Resiliência (Ref.
120179): Elevada, tempo mínimo de duplicação da população menor que 15 meses (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
59153): Low vulnerability (16 of 100).
