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=0.01148 (0.00483 - 0.02731), b=2.98 (2.80 - 3.16), in cm total length, based on LWR estimates for this Genus-body shape (Ref.
93245).
Nivel trófico (Ref.
69278): 3.2 ±0.43 se; based on food items.
Resiliencia (Ref.
120179): Bajo, población duplicada en un tiempo mínimo de 4.5-14 años (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
