Estimates based on models
Preferred temperature (Ref.
123201): 6.8 - 9.8, mean 7.8 °C (based on 186 cells).
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01148 (0.00731 - 0.01803), b=3.05 (2.92 - 3.18), in cm total length, based on LWR estimates for this species & Genus-body shape (Ref.
93245).
Trophic level (Ref.
69278): 4.0 ±0.67 se; based on food items.
Generation time: 15.7 ( na - na) years. Estimated as median ln(3)/K based on 1
growth studies.
Resilienza (Ref.
