Abstract
Comprehensive studies were carried out on three water bodies in the Astrakhan region at different distances from the locations of active fish farms. Standard methods of chemical laboratory analysis were used to determine the hydrochemical parameters. As a result of the studies it has been determined that the quality of the aquatic environment of the studied natural water bodies is heterogeneous. This is due both to the natural redistribution of the values of the hydrochemical parameters under consideration and to the change in their quantity as a result of the activities of arable fish farms. The most informative water parameters of natural water bodies of Astrakhan region at the stage of organization of fish farms were determination of characteristics of oxygen regime, degree of organic pollution and quantity of such biogenic elements, as mineral nitrogen and phosphorus in the water of streams potentially considered for cropping fish. The above-mentioned environmental parameters, as well as weighted substances, can be recommended for productive ecological monitoring in the operation phase of agricultural fish farms. The hydrochemical parameters of the environment, the definition of which is recommended in watercourses of the Astrakhan region at the stage of organization and operation of farm fish farms.
