SIZE-AGE AND SPECIES COMPOSITION OF FISH IN RESERVOIRS OF KARAGANDA REGION

Abstract

The article presents the results of the study of morphobiological characteristics, composition and species composition of ichthyofauna of water bodies of Karaganda region. 4 species of nurseries, 2 species of fish-breeding have been identified on Toksymak lake. On the DSU-58 dam, only a representative of the seed was known. Only one species of silver carp was found on dam No. 1 and lake Balyktykol. Morphological and biological analysis of fish was carried out. According to the size composition, it is possible to note the frequency of the meeting of the silver Karak and the valley on the Toksymak lake and the DSU-58 dam. In all reservoirs, the length and weight of the body are preserved in the studied species, some species have a high omission in Fulton. This means sufficient provision of fodder. According to the results of the study, the condition and species composition of fish on the dams DSU-58, No. 1, lakes Toksymak and Balyktykol were established.
