Estimates based on models

Preferred temperature (Ref. 115969): 0.6 - 10.3, mean 5.6 (based on 824 cells).

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

Bayesian length-weight: a=0.00646 (0.00554 - 0.00753), b=3.06 (3.02 - 3.10), in cm Total Length, based on LWR estimates for this species (Ref. 93245).

Trophic level (Ref. 69278): 4.1 ±0.0 se; based on diet studies.

Resilience (Ref. 120179): Low, minimum population doubling time 4.5 - 14 years (rm=0.43; K=0.06-0.12; tm=2-11; tmax=30; Fec=50,000).

Prior r = 0.19, 95% CL = 0.12 - 0.28, Based on 2 full stock assessments.

Fishing Vulnerability (Ref. 59153): High to very high vulnerability (66 of 100).

Climate Vulnerability (Ref. 125649): Moderate to high vulnerability (46 of 100).

Price category (Ref. 80766): High.
