Estimates based on models

Preferred temperature (Ref. 115969): 11.9 - 19.7, mean 15 (based on 71 cells).

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

Bayesian length-weight: a=0.00851 (0.00551 - 0.01314), b=3.13 (3.00 - 3.26), in cm Total Length, based on LWR estimates for this species & Genus-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.4 ±0.44 se; based on food items.

Resilienza (Ref. 120179): Medio, tempo minimo di raddoppiamento della popolazione 1.4 - 4.4 anni (K=0.26).

Prior r = 0.55, 95% CL = 0.36 - 0.82, Based on 2 data-limited stock assessments.

Fishing Vulnerability (Ref. 59153): Moderate vulnerability (44 of 100).

Climate Vulnerability (Ref. 125649): Moderate vulnerability (41 of 100).

Price category (Ref. 80766): Low.
