The length of the rivers in Uzbekistan and the presence of all the biotopes in the mollusks have made they a favourable reservoir for the mollusks. However, it should be noted that all species in the rivers differ in their density. Rivers and fishery farms play a great role in formation of bivalve mollusks fauna in the canals. It was studied the fishery farms of the Syrdarya River and its surroundings have a major effect on the fauna of the Mirzachul and South Mirzachul canals; the Zarafshan River’s effect on spreading of bivalve mollusks in the Dargom and Eskiankhor canals; the Amudarya River and its surrounding areas influence of fishery farms on the fauna of the Amu-Bukhara, Kizketgan and Karshi main canals. Colletopterum family breeds in the water studied, do not show any superiority in natural or artificial reservoirs compared to other breeds. Three species of these family are included in the Red Book of the Republic of Uzbekistan (C.baсtrianum, C. cyreum sogdianum, C. kokandicum). C. Bactrianum can be found only in rivers in the middle Zarafshan and Amudarya, in the Syrdarya river (Syrdarya Region only), in the reservoir and in the fishery farms only in Chelak, and the canals only in the Tuyatortar and Mirzachul canals.
