Estimates based on models

Preferred temperature (Ref. 123201): 4 - 4.5, mean 4.1 °C (based on 7 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5625   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00302 (0.00141 - 0.00645), b=3.24 (3.07 - 3.41), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Nivel trófico (Ref. 69278):  3.6   ±0.4 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):  Moderate to high vulnerability (47 of 100).
