The Significance of Dicotyledonous Mollusks of the Unionidae Family in the Aquatic Ecosystems of Uzbekistan in Food and Economy

Abstract

Chinese complex fish species - Oq Amur (Ctenopharyngodon idella) and oqKhumbosh (Hypophthalmichthys molitrix) spread in Uzbekistan waterecosystem were studied the spread as result of acclimatization ofSinanodonta gibba, S. orbicularis and S. puerorum bivalve molluscs togatherwith fish to the ecosystem of Syrdarya, Amudarya and Zarafshan rivers ofUzbekistan.This is because the larvae-gloxidia of the Chinese toothlessSinanodonta seed are parasitic in these fish. The distribution of Sinanodontagibba, S. orbicularis and S. ruerorum bivalve molluscs in the aquaticecosystems of Uzbekistan under human influence has led to an expansion ofthe range of these species. The role of Sinanodonta seeds in the distribution,distribution, ecology, increasing the productivity of water bodies, in foodwas analyzed for the first time in a comprehensive way
