The article presents the results of research on the current state of the Aral Sea. An estimate of the area of the residual reservoir is given, since the remaining area of the Aral Sea already belongs to the drying zone. The paper describes the processes of modern sedimentation in the residual reservoir of the Aral Sea, meaning only the Western deep-water part of the sea, the area of which is 1/10 of the full-water Aral Sea, and the salinity of the water as shown by chemical analyses has increased more than 10 times (110-120 g/ l). The purpose of the study is to observe changes in the state of physical, chemical and biological ecosystems of the water masses of the residual reservoirs of the Aral Sea in the conditions of the current ecological crisis, as well as to study the mechanism of their adaptation to the conditions of a shortage of desalination runoff and the dryness of the regional climate. The species composition and the number of inhabitants of the reservoir depend on the properties and level of salinity of the water. The main idea of environmental monitoring is that hydrobionts reflect the prevailing environmental conditions in the reservoir. Those species, for which these conditions are unfavorable fall out, being replaced by new species with different needs.
