Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01380 (0.00641 - 0.02973), b=3.03 (2.86 - 3.20), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (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):  Moderate vulnerability (40 of 100).
Price category (Ref. 80766):   High.
