The aim: to study the distribution, population dynamics and rational use of commercial fish species in the Southern fishery region of the Volga-Caspian fishery basin in 2000–2020. Particular attention was paid to the possibility of resuming the domestic fishing of Caspian keels, which constitute a reserve of the raw material base for increasing the Russian catch in the Caspian Sea. Materials : in the period 2000–2020, field and expedition work was carried out annually on research and fishing vessels at standard landfills in the areas of the Northern Caspian Sea, as well as the delta and delta-front of the Volga River, where intensive industrial fishing is conducted. Along with the expedition research data, various statistical materials and Internet information were used. As results: — a nalysis of the state of the raw material base of commercial fish species for the period 2000–2020 and proposals for rational exploitation. Practical value : obtained result can be used to rationalize the management of stocks of commercial fish species.
