Estimates based on models

Preferred temperature (Ref. 123201): 4.6 - 9.4, mean 6.1 °C (based on 78 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 1.0000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01023 (0.00432 - 0.02423), b=3.00 (2.79 - 3.21), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Nivel trófico (Ref. 69278):  3.9   ±0.6 se; based on size and trophs of closest relatives
Resiliencia (Ref. 120179):  Medio, población duplicada en un tiempo mínimo de 1.4-4.4 años (Assuming tmax>3).
Fishing Vulnerability (Ref. 59153):  Low to moderate vulnerability (27 of 100).
