This article presents the results of studies on helminthological diseases of carp species living in the rivers Nura, Tengiz, Birtaban, Shalkar, Uyaly, Sholak, Alkasor of the Korgalzhyn region. 226 studied fish samples were subjected to comparative monitoring using helminthological methods. When examining the fish of the reservoirs of the Korgalzhyn district of the Akmola region, 41.1% of the fish were found unfit for organoleptic indicators. As a result of laboratory studies, fish samples taken from the Sholak, Alkasor and Uyaly rivers were recognized as unsuitable, while the indicators of the studied fish from the Nura river and lakes Shalkar, Tengiz, Birtaban were within the normal range. According to the study, 6.4% of diplostomiasis in Lake Shalkar and 28.6% of opisthorchiasis in Lake Alkasor are affected by helminthiases. 16.6% postdiplostomiasis in the lakes Shalkar and Birtaban, 10.5% opisthorchiasis in the Nura River. In Lake Sholak, ligulase was 9.1% .
