Estimates based on models

Preferred temperature (Ref. 123201): 6.2 - 11.9, mean 10.8 °C (based on 5 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00355 (0.00176 - 0.00714), b=3.09 (2.91 - 3.27), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Nível Trófico (Ref. 69278):  4.2   ±0.7 se; based on diet studies.
Resiliência (Ref. 120179):  Muito baixo, tempo mínimo de duplicação da população maior que 14 anos (Fec assumed to be <10).
Fishing Vulnerability (Ref. 59153):  High vulnerability (55 of 100).
