Estimates based on models

Preferred temperature (Ref. 123201): 4.2 - 6.5, mean 4.3 °C (based on 37 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5156 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00087 (0.00033 - 0.00229), b=3.07 (2.84 - 3.30), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.1 ±0.26 se; based on food items.

Resilienza (Ref. 120179): Basso, tempo minimo di raddoppiamento della popolazione 4.5 - 14 anni (Assuming tmax>10).

Fishing Vulnerability (Ref. 59153): Moderate vulnerability (41 of 100).
