Estimates based on models

Preferred temperature (Ref. 123201): 0.6 - 4.1, mean 1.7 °C (based on 108 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5312 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01175 (0.00541 - 0.02553), b=3.06 (2.86 - 3.26), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).

Niveau trophique (Ref. 69278): 3.6 ±0.58 se; based on food items.

Résilience (Ref. 120179): Milieu, temps minimum de doublement de population : 1,4 à 4,4 années (Assuming tmax>3).

Fishing Vulnerability (Ref. 59153): Low vulnerability (24 of 100).
