This paper presents the information on the history of appearance, modern composition, and distribution of fish species that have been introduced by man or have settled independently in the water bodies of the Krasnoyarsk Territory since the early 20th century. It is shown that the fish fauna composition has expanded mainly in the basin of the upper and middle Yenisei as well as in the basin of the Chulym that is a right tributary of the Ob; the fish fauna of the Pyasina and Khatanga rivers that are beyond the Arctic Circle has remained unchanged. Eleven fish species and two subspecies are new for the region; among them, common bream and sunbleak have largely expanded their range in the Yenisei and Chulym basins; pike perch, Amur sleeper, and bleak have enlarged their range only in the Chulym basin. The spread of other species is limited by the regions of their artificial stocking. Peled that is common for the northern regions of the territory was resettled in the Krasnoyarsk Reservoir; the status of Prussian carp that was introduced from the Amur River and degree of its assimilation with the local populations of this species are not clear.
