Abstract
The nature and methods of fishing become extremely important in inland waters with a limited raw material base and sharply changing reproductive capacity of fish herds under the influence of habitat. Currently, 19 species of semi-passable and river fish are used in the Astrakhan region. All these species live in a single water area and practically do not create local singlespecies clusters. The modern resource base of semi-navigable and river fish, on which industrial fishing in the Astrakhan region is based, is limited. Stocks of a number of fish species are declining – roach, tench, pike. Stocks of others are stagnating at a low level – bream, catfish. At the same time, the annual increase in fishing intensity due to the commissioning of new fishing sites does not compensate for the decrease in commercial catches, which indicates the tense state of the fishing resource base in the Astrakhan region.
