Estimates based on models
Preferred temperature (Ref.
123201): 6.2 - 9.9, mean 7.8 °C (based on 70 cells).
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00251 (0.00128 - 0.00492), b=3.19 (3.03 - 3.35), in cm total length, based on LWR estimates for this Genus-body shape (Ref.

Trophic level (Ref.
69278): 3.2 ±0.31 se; based on food items.
Resilience (Ref.
120179): Low, minimum population doubling time 4.5 - 14 years (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
