RESULTS OF RESEARCH ON THE POSSIBILITY OF ARTEMIA INDUSTRIAL EXPLOITATION IN NATURAL RESERVOIRS OF THE ASTRAKHAN REGION AND EVALUATION OF THE FEASIBILITY OF THE PASTURE AQUACULTURE IN HYPERHALINE WATER BODIES DEVELOPMENT IN THE ASTRAKHAN REGION AND REPUBLIC KALMYKIA
The paper presents the materials of the appraisal hyperhaline water bodies of the Astrakhan region and Republic Kalmykia. The aim of the work was to assess the possibility of industrial exploitation of Artemia in natural reservoirs of the Astrakhan region and the feasibility of developing pastoral aquaculture in these regions. The results showed that reservoirs suitable for Artemia crustaceans and, consequently, for their cultivation (especially by extensive aquaculture methods) are extremely small and are mainly directly dependent on feeding (mostly forced), often degrade or disappear altogether in a dry climate. Due to the peculiarities of the water management situation, the strong variability in the long-term aspect of environmental conditions, especially salinity, in hyperhaline water bodies, makes it difficult to obtain a stable harvest of Artemia and thus to conduct pastoral aquaculture of this species.
