Estimates based on models

Preferred temperature (Ref. 115969): 2.1 - 14.1, mean 6.3 (based on 199 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.6250 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00302 (0.00169 - 0.00538), b=3.03 (2.87 - 3.19), in cm Total Length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).

Niveau trophique (Ref. 69278): 4.5 ±0.6 se; based on diet studies.

Résilience (Ref. 120179): Faible, temps minimum de doublement de population : 4,5 à 14 années (K=0.13-0.16; tm=8-11; tmax=20).

Prior r = 0.31, 95% CL = 0.20 - 0.46, Based on 3 full stock assessments.

Fishing Vulnerability (Ref. 59153): Very high vulnerability (75 of 100).

Climate Vulnerability (Ref. 125649): Moderate to high vulnerability (47 of 100).

Catégorie de prix (Ref. 80766): Low.
