Biological indicators of the main commercial fish species (Caspian roach, kutum, bream, Caspian vimba, shemaya) of the Samur coast of the Caspian Sea

Based on ichthyological materials collected in 2022-2024 on the Samur coast of the Caspian Sea, the biological indicators of the main commercial fish species such as Caspian roach, kutum, bream, Caspian vimba and shemaya are considered. It is shown that in the considered part of the Caspian Sea, the biological parameters of the commercial fish species studied by us are currently in a more favorable condition compared to the Agrakhan and Kizlyar bays.
