Estimates based on models

Preferred temperature (Ref. 115969): 1.1 - 5.9, mean 3.7 (based on 205 cells).

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

Bayesian length-weight: a=0.01023 (0.00652 - 0.01607), b=3.10 (2.97 - 3.23), in cm Total Length, based on LWR estimates for this species & Genus-body shape (Ref. 93245).

Nível Trófico (Ref. 69278): 4.3 ±0.3 se; based on diet studies.

Resiliência (Ref. 120179): Muito baixo, tempo mínimo de duplicação da população maior que 14 anos (tmax=157; k=0.04).

Prior r = 0.04, 95% CL = 0.03 - 0.06, Based on 2 full stock assessments.

Fishing Vulnerability (Ref. 59153): High to very high vulnerability (74 of 100).
