Estimates based on models

Preferred temperature (Ref. 123201): 6.6 - 15.5, mean 10.1 °C (based on 302 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5625 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.02291 (0.01031 - 0.05092), b=2.94 (2.74 - 3.14), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Nivel trófico (Ref. 69278): 3.4 ±0.2 se; based on size and trophs of closest relatives

Resiliencia (Ref. 120179): Medio, población duplicada en un tiempo mínimo de 1.4-4.4 años (Assuming Fec<1000).

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).
