Estimates based on models

Preferred temperature (Ref. 115969): -1.1 - 2.9, mean 1.5 (based on 50 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.7500 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00117 (0.00100 - 0.00138), b=3.47 (3.42 - 3.52), in cm Total Length, based on LWR estimates for this species (Ref. 93245).

Niveau trophique (Ref. 69278): 3.2 ±0.2 se; based on diet studies.

Résilience (Ref. 120179): Milieu, temps minimum de doublement de population : 1,4 à 4,4 années (K=0.13-0.39; tmax=13; tm=4; Fec=3,094).

Prior r = 0.39, 95% CL = 0.26 - 0.59, Based on 2 data-limited stock assessments.

Fishing Vulnerability (Ref. 59153): Moderate vulnerability (35 of 100).

Climate Vulnerability (Ref. 125649): High to very high vulnerability (68 of 100).

Catégorie de prix (Ref. 80766): Very high.
