Abstract
Based on ichthyological materials collected in 2022-2023 in the northern part of the Agrakhan Bay of the Caspian Sea, biological indicators of silver carp, rudd, carp, roach, bream are considered. It is shown that in the considered part of the Caspian Sea, at present, despite a slight decrease in biological indicators, the condition of the groups of dominant fish species is favorable.
