Estimates based on models

Preferred temperature (Ref. 123201): 6.9 - 12.5, mean 9.2 °C (based on 58 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 1.0000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00129 (0.00081 - 0.00204), b=3.14 (3.00 - 3.28), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).
Trophic level (Ref. 69278):  3.7   ±0.53 se; based on food items.
Resilience (Ref. 120179):  Low, minimum population doubling time 4.5 - 14 years (Assuming tm>4).
