Estimates based on models

Preferred temperature (Ref. 115969): 17.5 - 23.6, mean 20.2 (based on 66 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00263 (0.00139 - 0.00497), b=3.21 (3.04 - 3.38), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Nivel trófico (Ref. 69278):  4.0   ±0.5 se; based on size and trophs of closest relatives
Resiliencia (Ref. 120179):  Bajo, población duplicada en un tiempo mínimo de 4.5-14 años (Preliminary low fecundity).
Fishing Vulnerability (Ref. 59153):  Low to moderate vulnerability (34 of 100).
