The parasite fauna of fish species, acclimatized in the reservoirs of Ukraine, Uzbekistan, Ru- ssia, and Vietnam basin is reviewed and compared to that in the rivers of Amur Basin and water reservoirs of China, where they were brought from. The characteristic of the new-tenants parasites is given and their pathogenous forms are recorded.
