The Amur sleeper was missed in the ichthyofauna of Transbaikal Siberia. Its appearance
was noticed in the waters of the Upper Amur basin, including the Shilka River at the end of the
last century. Habitability conditions of the Amur sleeper in the Shilka, its morphological features,
its size and weight characteristics, its fatness and peculiarities of its feeding were researched.
The study reveals some differences in the metrical features of the Amur sleeper in different water
tracks of the Shilka. Size estimation shows that the Amur sleeper is flexible and possesses great
adaptive capabilities.
Feeding peculiarities of the Amur sleeper are characterized by a wide ecological range
enabling it to feed on diverse fodder organisms and promptly switch from carnivorous to
euryphagous type of feeding. The study shows that in the water bodies of the Shilka basin the
Amur sleeper reproduces fast, reaches great numbers and is able greatly to damage the aboriginal
ichthyofauna that contains valuable and endemic fish species.
