Estimates based on models

Preferred temperature (Ref. 115969): 5.7 - 11.3, mean 7.6 (based on 24 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5625 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00708 (0.00463 - 0.01083), b=3.11 (2.98 - 3.24), in cm Total Length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).

Niveau trophique (Ref. 69278): 3.7 ±0.1 se; based on diet studies.

Résilience (Ref. 120179): Faible, temps minimum de doublement de population : 4,5 à 14 années (tm=1-3; Fec=72,000; tmax=27).

Prior r = 0.48, 95% CL = 0.32 - 0.73, Based on 4 full stock assessments.

Fishing Vulnerability (Ref. 59153): Moderate to high vulnerability (45 of 100).

Climate Vulnerability (Ref. 125649): Low to moderate vulnerability (28 of 100).

Catégorie de prix (Ref. 80766): Low.
