Estimates based on models
Preferred temperature (Ref.
123201): 11.8 - 24.9, mean 15.8 °C (based on 168 cells).
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00043 (0.00024 - 0.00076), b=3.23 (3.08 - 3.38), in cm total length, based on LWR estimates for this species & Genus-body shape (Ref.
93245).
Trophic level (Ref.
69278): 3.7 ±0.59 se; based on food items.
Generation time: 7.3 ( na - na) years. Estimated as median ln(3)/K based on 1
growth studies.
устойчивость к внешним воздействиям (Ref.
