Changes in Zooplankton Communities of Some Lakes of the Republic of Karakalpakstan in an Ecologically Changed Environment

Аннотация

Previously, the Aral Sea and its delta reservoirs had a unique hydro fauna. They included a number of endemic taxa of mosses, mollusks, crustaceans, and fish. Until the mid-30s of the last century, the zooplankton of the lake. Sudochie was completely freshwater. It included 38 species of rotifers, 32 species of branchous and 9 species of copepods. As a result of hydro geographic changes in the delta of the Amu Darya River, the biotic population of the Aral Sea and the northwestern delta lakes of the Amu Darya River have changed. So, the variety of branchous in Sudochie has halved.
