In this paper, the catches of silver carp for 2005-2020 are analyzed. Qualitative indicators of silver carp in the northeastern part of the Caspian Sea have been studied. As a result of the study, it was revealed that the main biological indicators of this species (mass, length, age) for 2012-2021 vary within small limits, which indicates stable reserves of this species in the Kazakh sector of the Caspian Sea.

Key words: crucian carp, catch, Ural-Caspian basin, length, mass, parasitofauna.
