Estimates based on models

Preferred temperature (Ref. 123201): 10.4 - 16.3, mean 11.4 °C (based on 5 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 1.0000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00372 (0.00188 - 0.00734), b=3.10 (2.92 - 3.28), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Nivel trófico (Ref. 69278): 4.5 ±0.4 se; based on diet studies.

Resiliencia (Ref. 120179): Bajo, población duplicada en un tiempo mínimo de 4.5-14 años (Fec assumed to be <100).

Fishing Vulnerability (Ref. 59153): Moderate vulnerability (42 of 100).
