Estimates based on models
Preferred temperature (Ref.
123201): 7.6 - 11.2, mean 8.6 °C (based on 36 cells).
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5625 [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): 3.2 ±0.40 se; based on food items.
Generation time: 2.4 ( na - na) years. Estimated as median ln(3)/K based on 1
growth studies.
Widerstandsfähigkeit (Ref.
120179): mittel, Verdopplung der Population dauert 1,4 - 4,4 Jahre. (Assuming tmax>3).
Fishing Vulnerability (Ref.
