Abstract

Chinese complex fish species - Oq Amur (Ctenopharyngodon idella) and oq Khumbosh (Hypophthalmichthys molitrix) spread in Uzbekistan water ecosystem were studied the spread as result of acclimatization of Sinanodonta gibba, S. orbicularis and S. puerorum bivalve molluscs togather with fish to the ecosystem of Syrdarya, Amudarya and Zarafshan rivers of Uzbekistan. This is because the larvae-gloxidia of the Chinese toothless Sinanodonta seed are parasitic in these fish. The distribution of Sinanodonta gibba, S. orbicularis and S. ruerorum bivalve molluscs in the aquatic ecosystems of Uzbekistan under human influence has led to an expansion of the range of these species. The role of Sinanodonta seeds in the distribution, distribution, ecology, increasing the productivity of water bodies, in food was analyzed for the first time in a comprehensive way.
