The preliminary results of contemporary investigations of fish diversity in the Amur Basin: species structure on the boundary of XX-XXI centuries Novomodnyy G.V. Khabarovsk Branch Pacific Research Fisheries Centre. [email protected], [email protected] In 2001 the author begun the phonographic (Digital-Photo) and museum collection of the Amur River fishes. Current findings on the species diversity of the Amur River underlie in this work (foremost Annotated Check-List of Cyclostomata and Fishes of the Continental Waters of Russia (1998); Fauna Sinica Osteichthys: Cypriniformes (1998 end 2000), Siluriformes (1999); Description of species inhabiting the Heilongjiang Province (1995); revision of loaches made by Vasili’eva (2001). Results of expeditions carried by author in 2001-2002: • discovery of Rhodeus ocellatus in waters of the Amur River (the Kiya River belonging to the Ussuri and the Bira River belonging to the Middle Amur basin). • discovery of twin species, hiding under taxons Acanthorhodeus asmussii and Acanthorhodeus chankaensis (species derived from the group “chankaensis”= A. gracilis (Korea), second species in the group “asmussii” is possibly A.macropterus. • discovery of Lefua costata in the Khor River (the Ussuri Basin) Ladislavia taczanowskii the Kiya, Khor, Bolshaya Ussurka, Anuy (The Lower Amur); Micropercops cinctus and Paramisgurnus dabrianus near Khabarovsk city; Misgurnus anguillicaudatus in the Sungari basin (these fishes bought alive on the market in Harbin with other species of loach); • information: where? when? and what fishing gear? to catch species • new data about some species abundance that were be consider as rare. • collection of own digital photos of 88 species from the Amur River made in vital staining Own investigations, analysis of scientific sources, help of colleagues allowed to count 133 species in the Amur basin (including brackish waters of the Amur Estuary) (Table 1). With this 26 species were included to «Annotated Check-List…», one species Sarcocheilichthys soldatovi was deleted from this list. Approximately 18 species were introduced in the Amur by man: the introduction of 6 species was intentional; 13 species from 18 were acclimatized, 7 species were distributed outside waters of allocation. The development of artificial propagation in the Ussuri basin changes the list of species introduced in the Amur River. The list of the Amur River species includes also 7 marine and 1 euryhaline species. 7 anadromous species run occasionally in the Amur River. 8 species from the list don’t exist in Russian waters. The existence of 4 species is disputable. Now the Khabarovsk Branch of Pacific Research Fisheries Center intensified the faunal investigations. Almost all scientists working on rivers of the Khabarovsk Territory are brought to collect the Amur Basin species. Thanks to Sergey Zolotukhin for constant help to catch this collection. We thanks also Alexander Antonov (Institute of Water Problems, Khabarovsk), Mikhail Skopets (Wild Salmon Center, Portland), Igor Frolov (Department of Fisheries of the Khabarovsk Territory), Sergei Mokrov (Fish Conservation Inspection of Birobizhan) for investigation of mountainous rivers of the Khabarovsk Territory. We offer special thanks to university-fellow Sergey Shedko (Institute of Biology and Soil Science, Vladivostok) as a high professional opponent of author's too fast deductions. 1 Table 1.
