Ecology Summary - Thymallus tugarinae

Langue:

Réf. Princ.	Knizhin, I.B., A.L. Antonov, S.N. Safronov and S.J. Weiss, 2007
Remarques	The species spawns in rivers of the Amur Basin from the middle to the end of May, 7-10 days before the T. grubei flavomaculatus. The autumn downstream migration in tributaries of the lower Amur takes place from September to October. The range of the food components of the Lower Amur grayling in the Anyui River in July is represented by various zoobenthos organisms. The most weight part in the food boluses of fish older than the age 3+ is represented by mayfly and stonefly larvae, imago caddis and bugs. The composition and the frequency of occurrence of different organisms in the food boluses of the Lower Amur grayling. Comparison of the feeding spectra in the Lower Amur and yellow-spotted graylings caught in the same stations did not reveal any significant differences in the diversity of the food components (Ref. 57969).
