This work presents the results of comparative analysis of fish fauna in the border protected areas of the Middle Amur River basin: Honghe and Bachadao nature reserves (Heilongjiang Province, China) and the Bastak Nature Reserve (Jewish Autonomous Oblast, Russia). The data were obtained during the first joint Russian-Chinese studies during 2017–2019. Thirty five species of fish were recorded in the Honghe Nature Reserve. These species included small lowland river fish from four orders dominated by Cypriniformes. Forty five species of fish and jawless fish from eight orders were recorded in the Bachadao Nature Reserve. Both reserves were dominated by the Chinese autochthonous complex of plain fish fauna, 43 % and 40 %, respectively. Fish fauna of the Bastak Nature Reserve consists of 61 species, including 38 species in the Central cluster and 49 species in the Zabelovsky cluster. Fish fauna of the Zabelovsky cluster and the Bachdao Nature Reserve have a lot in common.
