Estimates based on models

Preferred temperature (Ref. 115969): 12.3 - 22.9, mean 15.9 °C (based on 152 cells).
Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01023 (0.00668 - 0.01568), b=2.97 (2.84 - 3.10), in cm total length, based on LWR estimates for this species & Genus-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.9   ±0.4 se; based on diet studies.
Generation time: 4.7 ( na - na) years. Estimated as median ln(3)/K based on 2 growth studies.
