Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5312   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00490 (0.00229 - 0.01045), b=3.08 (2.91 - 3.25), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Nivel trófico (Ref. 69278):  4.2   ±0.7 se; based on size and trophs of closest relatives
Resiliencia (Ref. 120179):  Bajo, población duplicada en un tiempo mínimo de 4.5-14 años (Fec assumed to be <100).
Fishing Vulnerability (Ref. 59153):  Very high vulnerability (90 of 100).
