Distribution of hydrobionts in aquatic ecosystems in different parts of the akdaryo river

Abstract

The work covers a comparative analysis of the distribution of hydrobionts in water ecosystems in different parts of the Okdarya River. The distribution of 22 species in the area near Chelak city of Akhdarya and 20 species in the area after the Akhdarya reservoir was researched and studied. Ecological groups of hydrabionts distributed in biotopes of the Akdarya River were analyzed depending on their habitat. In the river, there are 8 types of peloreophiles in 28.5%, 3 types of rheophiles in 11%, 1 type of pelolimnophiles in 3.5%, 8 types of phytophiles in 28.5%, 1 type of telmotophiles in 3.5% and 1 type of phytophiles in 3.5%, phyto-lithoreophiles 7% of type 2, 11% of 3 types of phytopelophiles and 3.5% of 1 type of lithoreophiles were studied.
