Estimates based on models
Preferred temperature (Ref.
123201): 4.2 - 7.7, mean 5.7 °C (based on 645 cells).
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.7656 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00933 (0.00363 - 0.02397), b=3.07 (2.85 - 3.29), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Trophic level (Ref.
69278): 3.1 ±0.30 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.
59153): Low to moderate vulnerability (27 of 100).
