BIO-ECOLOGICAL FEATURES OF BLACKFISH (SCHIZOTHORAX INTERMEDIUS) IN CHERVOK RESERVOIR

In our scientific research on the blackfish (Schizothorax intermedius) species in the Chervok reservoir, we will study its bio-ecological characteristics, nutritional composition, age and growth rates, analyze the current ichthyofauna of the reservoirs in the Chervok reservoir; Studying the bio-ecological characteristics of blackfish in Chervok reservoir; to study the nutritional composition and growth rates of blackfish; For the first time in the study, the population, structure, including size and growth, reproductive biological indicators, changes in external environmental factors on the growth and development of blackfish (Schizothorax intermedius) in Chervok Reservoir were investigated. observed, explained on the basis of experiments. Currently, 51 reservoirs are operating in our republic, they are mainly important for irrigation. Their total project volume is 18.8 km3, useful - 14.8 km3. The largest reservoirs are: Tuyamoyin, Chorvok, Tudakol, Kattakorgan. They were built to control river flows throughout the year, to use them during crop irrigation, and to prevent floods in emergencies.
