Species composition and ecological groups of mollusks with two levels of water reservoirs of Uzbekistan

In the Chimkurgan reservoir there are 11 species and 2 subspecies belonging to 4 families. 11 species of mollusks belonging to 6 families were found in the Qoratepa reservoir. 5 species of Corbicula cor, C. fliminalis, C. purpurea, Corbiculina tibetensis and C. ferghanensis distributed in the Chimkurgan reservoir are eurybiont species and 9 species...

In the aquatic ecosystems of the Amu-Bukhara Reservoir and its environs, 10 species of mollusks and 2 subspecies of mollusks have been identified, which belong to 2 families and 4 genera. It was found that in the reservoir they were distributed in stony soils (2), sandy soils (5) and silts (9). The distribution of 6 species of mollusks and 1 subspe...

As a result of the study, it has been identified that the water temperature in the Kashkadarya River is 18–24 °C, the water clarity is 0.51–0.62 m and the water flow rate is 0.72–0.84 m/sec. The species of bivalve mollusks Sinanodonta gibba, S. orbicularis, S. puerorum, Colletopterum cyreum sogdianum, Corbicula cor, C. fluminalis, C. purpurea, Corb...

The work examines the vital activity of mollusks. About 160 species of terrestrial mollusks have been identified in Uzbekistan. It has been established that 12 species of terrestrial mollusks live on the plains in the steppe serozem soils at heights. Psychromezobionts live in hydromorphic soil among turf and under stones. Typical and dark soils are...

The length of the reservoir area on the banks of the Zarafshan River and the presence of all biotopes inhabited by molluscs of the Unionidae and Corbisulidae families have made the basin a comfortable aquatic ecosystem for molluscs. The influence of rivers and fisheries on the formation of the fauna of bivalve molluscs in reservoirs is significant....

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 fi...

The study assessed the current state of the population of Colletopterum bactrianum in Uzbekistan reservoirs from the rivers Syr-Darya, Syr-Darya region, middle Zarafshan and Amu-Darya. At the same time, individual and organismic indicators in the population were compared. Differentiation of the C. bactrianum population in water bodies is determined...
