Background and Aim. Lakes Samal, Kimasar and Shokpartas pond, located in the protected areas of Karkaralinsky National Park, are used for recreational purposes. Despite the use of the natural resources, the lakes are insufficiently studied. The purpose of the work is to conduct research to assess the species composition and current state of fish populations.
Materials and methods. Scientific research work on the reservoirs of the Karkaralinsky GNPP was carried out in 2024, as a result, the state of fish populations in the Samal, Kimasar lakes and Shokpartas pond were studied according to standard ichthyological research methods.
Results. In conclusion, 7 species from the family of carp, perch and pike were identified in the reservoirs of the Karkaralinsky SNNP. When studying Siberian roach, the age composition in catches was incomplete and included individuals from three to seven years old. Fulton's fatness is on average consistent with regional indicators. All studied reservoirs inhabited by Chinese carp were stocked with carp. The fatness rates of Chinese carp are significantly higher in Lake Kimasar compared to the other. The northern pike lives in two reservoirs of the national park – lakes Samal and Kimasar. According to the age composition of river perch, three-year-old fish dominate.
Conclusion. As a result, the state of fish populations in Samal, Kimasar Lakes and Shokpartas pond was studied. The ichthyofauna includes seven species (Chinese carp, carp, Siberian gudgeon, stone morocos, Siberian roach, northern pike, river perch), of which four are native and three are acclimatized. Potentially commercial species are Siberian roach, Chinese carp, common pike and common perch. There was no carp in the catches. The biological parameters of these species are quite satisfactory. In order to maintain existing carp herds, it is recommended to stock fingerlings and adults for the organization of sports and amateur fishing directly.
