Estimates based on models

Preferred temperature (Ref. 123201): 4.5 - 13.9, mean 8.5 °C (based on 849 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 1.0625 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01549 (0.00732 - 0.03276), b=3.00 (2.81 - 3.19), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).

Trophic level (Ref. 69278): 3.5 ±0.48 se; based on food items.

Fishing Vulnerability (Ref. 59153): Low to moderate vulnerability (30 of 100).
