Estimates based on models

Preferred temperature (Ref. 115969): 3.6 - 6.1, mean 4.3 °C (based on 43 cells).
Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00513 (0.00254 - 0.01037), b=3.11 (2.94 - 3.28), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).
Nivel trófico (Ref. 69278):  4.0   ±0.69 se; based on food items.
Resiliencia (Ref. 120179):  Bajo, población duplicada en un tiempo mínimo de 4.5-14 años (Fec assumed to be <100).
Vulnerability (Ref. 59153):  Very high vulnerability (87 of 100) .
