Estimates based on models

Preferred temperature (Ref. 123201): 8.9 - 11.4, mean 9.7 °C (based on 16 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00282 (0.00118 - 0.00673), b=3.10 (2.89 - 3.31), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Nivel trófico (Ref. 69278):  4.1   ±0.60 se; based on food items.
Resiliencia (Ref. 120179):  Bajo, población duplicada en un tiempo mínimo de 4.5-14 años (Assuming Fec <100).
Fishing Vulnerability (Ref. 59153):  Moderate to high vulnerability (47 of 100).
