Estimates based on models

Preferred temperature (Ref. 123201): 0.9 - 5.9, mean 3.9 °C (based on 236 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01000 (0.00499 - 0.02004), b=3.09 (2.92 - 3.26), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).

Niveau trophique (Ref. 69278): 3.4 ±0.4 se; based on diet studies.

Résilience (Ref. 120179): Très faible, temps minimum de doublement de population supérieur à 14 ans (K=0.18; tmax=57).

Prior r = 0.11, 95% CL = 0.07 - 0.16, Based on 4 full stock assessments.

Fishing Vulnerability (Ref. 59153): Moderate to high vulnerability (50 of 100).

Sebastes polyspinis (Taranetz & Moiseev, 1933)
