The history of the evolution of the ecosystem of the Aral Sea and the South Aral Sea is divided intotwo periods: the Late Holocene and the Anthropocene. The morphological indicators of the Aral Searemained relatively stable up to the early anthropocene, however, started degradation of its ecosystemin the 1960s. had very fast and irreversible character. Above all the increase in salinity of the Aral Seasince the 1960s had a catastrophic effect on its biodiversity, since in the early 1980s 70% of its watersurface and 50% of its water volume were still preserved. Consequently, the sea still possessed sufficientecological carrying capacity for the existence of aquatic life populations. At the same time, the mainproblem of preserving the biodiversity of aquatic ecosystems and developing fisheries in the SouthernAral Sea region in the Anthropocene is an extremely unstable and scarce water regime, which is aggravated by natural droughts, climate change, and deterioration in water quality. Especially the salinizationof terminal lakes and reservoirs leads to a decrease in biodiversity and biological productivity. The possible future of the Aral Sea depends entirely on possible human intervention, however, the future of theLarge Sea looks problematic, which can turn into a hypersaline reservoir. To improve the sustainabilityof hydroecosystems, it is first of all necessary: improving water management taking into account envi ronmental requirements for the conservation of biodiversity and developing fisheries, accelerated implementation of water- saving irrigation technologies, introduction of intensive aquaculture and culturebased fisheries, diversification of aquaculture by introducing salt tolerant species, strengthening researchactivity in research institutes and international cooperation.Key words: Aral Sea, Priaralye, anthropocene, salinization, fish economy
