Research work on hyperhaline lakes was started in 1977. Commercial interest in artemia (at the stage of cysts) as a starting feed for hydrobionts served as a basis for monitoring studies of hypergalin lakes of the Altai Territory. Lake Dushnoye is located in the Nizhne-Kasmalinsky system of lakes, which belongs to the vast Kulunda-Kasmalinsky basin of Artemia lakes, which is the basis of the resource base of artemia in the south of Western Siberia in terms of the number of water bodies. As a result of complex hydrobiological surveys in the spring period from April to May 2018, the dynamics of the indices of the number of different stages of development of the crustacean (nauplii, juvenile, pre-adult, adult, cysts, summer eggs), their percentage ratio, size-age structure of the population, productivity of the crustacean Artemia Leach, 1819, morphometric parameters of mature individuals and cysts of Lake Dushnoye in the Altai Territory in comparison with similar indicators for 2017. The temperature regime at the beginning of the vegetation period of the current year was unfavorable for the development of artemia in lakes, which led to low numbers of crustaceans. According to the results of monitoring studies of the hypergalin lake of the Altai Territory in the spring (April and May 2018), during the development of the first generation of crustaceans, a depressive the state of development of the population of the brine shrimp in Lake Dushnoye, Volchikhinsky district. A potential stock of Artemia cysts is given.
