Estimates based on models
Preferred temperature (Ref.
123201): 7.1 - 10.2, mean 8.4 °C (based on 170 cells).
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5001 [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.

Trophic level (Ref.
69278): 4.0 ±0.65 se; based on food items.
Fishing Vulnerability (Ref.
