Estimates based on models

Preferred temperature (Ref. 115969): 2.3 - 13, mean 9.9 (based on 221 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.7500   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00138 (0.00084 - 0.00228), b=3.21 (3.06 - 3.36), in cm Total Length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).
Trophic level (Ref. 69278):  3.1   ±0.30 se; based on food items.
устойчивость к внешним воздействиям (Ref. 120179):  средний (среднего размера), минимальное время удвоения популяции 1.4-4.4 года (Assuming tmax>3).
Fishing Vulnerability (Ref. 59153):  Low to moderate vulnerability (30 of 100).
