Estimates based on models

Preferred temperature (Ref. 123201): 3.5 - 13.5, mean 7.8 °C (based on 805 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 1.1250 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00102 (0.00046 - 0.00225), b=3.06 (2.88 - 3.24), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.1 ±0.30 se; based on food items.

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