Estimates based on models

Preferred temperature (Ref. 115969): -1.5 - 1.3, mean 0.2 (based on 411 cells).

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

Bayesian length-weight: a=0.00479 (0.00302 - 0.00758), b=3.18 (3.04 - 3.32), in cm Total Length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).

Niveau trophique (Ref. 69278): 3.9 ±0.59 se; based on food items.

Résilience (Ref. 120179): Faible, temps minimum de doublement de population : 4,5 à 14 années (K=0.056; Fec=400,000).

Prior r = 0.28, 95% CL = 0.19 - 0.42, Based on 1 data-limited stock assessment.

Fishing Vulnerability (Ref. 59153): Very high vulnerability (81 of 100).

Climate Vulnerability (Ref. 125649): Very high vulnerability (87 of 100).

Catégorie de prix (Ref. 80766): Low.
