From time immemorial, the city of Samarkand has been famous for its natural resources, pure spring waters and favorable climate. In the second half of the 14th and in the 50s of the 15th century, as well as in the 17th-18th centuries, Samarkand became one of the most prosperous and wealthy cities not only in Central Asia, but also in the entire East. Next to the new residences, luxurious palaces, new irrigation canals Abbas, Sieb, Obi Rahmat were built. The old irrigation systems of Dargomyzhsky, Stepnoy, Shavdorsky districts have been restored. Kora suv, Obi Mashhad, Obi-Rahmat are ditches formed by springs. Dozens of species of zoobenthos live in these waters - underwater organisms, some of which predominate in biocenoses in terms of numbers. Doctoral student of Samarkand State University Dildora Olimova is conducting a scientific research on the topic "Ecology of zoobenthic organisms in the city of Samarkand and its environs." Scientific Supervisor Professor of the Department of Ecology and Life Safety of SamSU Zuvaid Izzatullayev.

     “The underwater organisms we study are a collection of various animals that live under water in reservoirs,” says Dildora Olimova. - Their diversity: underwater insect larvae, mollusks, leeches, fish, rodents and other organisms serve as a source of food for underwater and waterfowl, reptiles and other organisms, even for humans. They live under water and filter water, that is, they are the orderlies of nature. With this in mind, a comprehensive study of underwater organisms of a certain territory, determination of the species composition of underwater organisms common in various types of waters, compilation of their modern taxonomy, characterization of ecological, biological and ecological groups, study of their harmful properties and development of measures for the protection of rare species acquire scientific and practical value and determine the relevance of the work. It is a source of food for most underwater organisms: fish, rodents, reptiles and amphibians. Moreover, some of their species, such as tubules, chironomids, mollusks, fish, are involved in the purification (filtration) of polluted waters, that is, they are good biological indicators.

    The main objectives of this study are to determine the composition and assessment of the current state of underwater organisms common in various water bodies of the city of Samarkand and its environs, as well as to analyze their distribution in water bodies and study the influence of environmental factors on them. Also important is the analysis of the economic importance of underwater organisms, the determination of their species composition rare and in need of protection, the development of recommendations for protection and the compilation of distribution maps.
