Gudgeons (Gobio) belong to one of the most widespread species of freshwater bony fishes in Eurasia. Gudgeons inheriting the water bodies of Kazakhstan, Siberia and the Amur basin differ from European species and their systematics needs detailed study. The endemic species of gudgeon G.acutipinnatus Men'shikov inhabits Lake Markakol. The taxonomic status of the gudgeon living in the Irtysh River basin is not clear. There are many small rivers in the Zaisan Basin, and the vast majority of them are almost unstudied. The purpose of this work was to establish the taxonomic status and assessment of the gudgeon on the example of the Beyittybulak River of East Kazakhstan. In 2022, gudgeon was one of the mass fish species in the Beyittybulak River. In the sample we studied, fish had typical for gudgeons shape and body colouration. Plastic features varied widely. Within the sample individuals differ in the position of fins and their shape, head shape and relative size of its different parts. The sample of gudgeons from the Beyittibulak River is represented by fish of different ages and sizes, so the conditions of existence are quite satisfactory for all life stages of this fish species.
