Bioresource potential of Phytoplankton of lake Khadicha (Bukhara, Uzbekistan)

Abstract

Abstract The most complete state of the aquatic ecosystem can be assessed by the composition of communities of aquatic organisms. The intensive supply of nutrients reduces the diversity and productivity of water bodies and increases the production of a limited number of species. In this article, the ecological state of the lake and its influence on the abundance and biomass of the phytoplankton composition of this lake are carried out. In the study of the shallow Lake Hadicha, a massive vegetation of the cyanobacterium Spirulina tenuissima Kütz was found. Large reserves of raw spirulina biomass in summer make it possible to use the lake as a source of valuable biological raw materials. Suburban reservoirs perform an important function of the regulator of the water regime of landscapes, they largely maintain its balance and redistribute moisture. At the same time, suburban water bodies are characterized by a high level of vulnerability, not only in case of excessive use of water resources, but also in the development of the adjacent territory.
