Estimates based on models

Preferred temperature (Ref. 115969): 25 - 29.1, mean 28.3 (based on 798 cells).

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

Bayesian length-weight: a=0.00851 (0.00777 - 0.00932), b=3.07 (3.05 - 3.09), in cm Total Length, based on LWR estimates for this species (Ref. 93245).

Trophic level (Ref. 69278): 3.6 ±0.6 se; based on diet studies.

Resilience (Ref. 120179): Medium, minimum population doubling time 1.4 - 4.4 years (K=0.14-0.41; tm=1; tmax=5; Fec= 53,676).

Prior r = 0.44, 95% CL = 0.29 - 0.66, Based on 1 full stock assessment.

Fishing Vulnerability (Ref. 59153): Moderate vulnerability (39 of 100).

Climate Vulnerability (Ref. 125649): Very high vulnerability (84 of 100).

Price category (Ref. 80766): High.
