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=0.01288 (0.00813 - 0.02041), b=2.91 (2.78 - 3.04), in cm total length, based on LWR estimates for this species & Genus-body shape (Ref.
93245).
Trofisk nivå (Ref.
69278): 3.4 ±0.38 se; based on food items.
Generation time: 1.3 ( na - na) years. Estimated as median ln(3)/K based on 1
growth studies.
Resiliens (Ref.
120179): Hög, lägsta populationsfördubblingstid mindre än 15 månader (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
