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 (0.00879 - 0.01499), b=3.00 (2.92 - 3.08), in cm total length, based on LWR estimates for this species (Ref.
93245).
Resiliencia (Ref.
120179): Medio, población duplicada en un tiempo mínimo de 1.4-4.4 años (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
59153): Low vulnerability (10 of 100).
