Abstract. The irrational use of fish resources, intensive development of agricultural land, anthropogenic impact, and processes of acclimatization have a significant influence on the aquatic ecosystems.As a result of the complex influence of negative impacts, the species composition of the ichthyofauna ofwater bodies undergoes significant changes, which leads the aquatic ecosystem to the chaos.In recent years, with the development of fisheries and aquaculture in the country, great importanceis attached to the protection and rational use of fish resources. In connection with this, work is underwayin the republic to study the ichthyofauna of especially important reservoirs in fisheries. However, sec- ondary water reservoirs, such as small and reserve, remain insufficiently studied, whereas such reservoirscan serve not only as a reserve for valuable commercial species, but also for the commercial cultivationof fish products.Lake Dereviannoe, located in the desert of Karabastau, in the Uighur district of Almaty region. In2018, the expeditionary detachment was first examined. The aim of the study was to study the conditionof the ichthyofauna of the reservoir. The study revealed that the ichthyofauna of the lake is representedby 14 species of fish belonging to 4 families: Cyprinidae – Cypriniformes, carpophages – Cyprinidontiformes, catfish – Siluriformes and percids – Perciformes. The composition of the ichthyofauna wasrepresented both by native and alien species. The proportion of alien species exceeded the aboriginalichthyofauna, but in terms of numbers, native species predominated.Key words: ichthyofauna, aboriginal, acclimatized, species, fish.
