Estimates based on models
Preferred temperature (Ref.
123201): 6.2 - 27.4, mean 16 °C (based on 3030 cells).
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.6250 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00389 (0.00180 - 0.00842), b=3.12 (2.94 - 3.30), in cm total length, based on all LWR estimates for this body shape (Ref.

Trophic level (Ref.
69278): 3.9 ±0.67 se; based on food items.
Resilience (Ref.
120179): Low, minimum population doubling time 4.5 - 14 years (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
