Estimates based on models

Preferred temperature (Ref. 123201): 4.9 - 10.1, mean 6.9 °C (based on 13 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.6250   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00661 (0.00225 - 0.01943), b=2.95 (2.71 - 3.19), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  4.0   ±0.66 se; based on food items.
جهندگی (Ref. 120179):  پايين ، كم, كمينه زمان لازم براي دو برابر شدن جمعيت 5/4 – 14 سال (Fec assumed to be <100).
Fishing Vulnerability (Ref. 59153):  Moderate vulnerability (41 of 100).
