Estimates based on models
Preferred temperature (Ref.
123201): 8.4 - 15.3, mean 11.4 °C (based on 187 cells).
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5029 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01202 (0.00911 - 0.01586), b=3.04 (2.96 - 3.12), in cm total length, based on LWR estimates for this species (Ref.
93245).
Trophic level (Ref.
69278): 4.2 ±0.73 se; based on food items.
Generation time: 5.1 ( na - na) years. Estimated as median ln(3)/K based on 2
growth studies.
