Estimates based on models

Preferred temperature (Ref. 123201): 12.3 - 22.9, mean 15.9 °C (based on 152 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01047 (0.00646 - 0.01697), 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.
Resilience (Ref. 120179):  Medium, minimum population doubling time 1.4 - 4.4 years (tm=3; K=0.23-0.28; Min batch fecundity >10,000).
