Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5039 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.02630 (0.01689 - 0.04095), b=2.96 (2.83 - 3.09), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref.
93245).
Trofisk nivå (Ref.
69278): 2.0 ±0.00 se; based on food items.
Generation time: 3.1 ( na - na) years. Estimated as median ln(3)/K based on 2
growth studies.
Resiliens (Ref.
120179): Mellan, lägsta populationsfördubblingstid 1,4-4,4 år (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
