The article presents the analysis and prospects of commercial aquaculture in the southern regions of Russia. Rostov and Astrakhan region and Krasnodar Krai are the leaders in commercial fish production. Rostov region annually grows 23-24 thousand tons. In Krasnodar region in the period from 2018 to 2022 there was a 15% growth of avcaculture production and in 2022 it was 23,3 thousand tons. In the Astrakhan region from 2018 to 2021 there was a decrease in this indicator by 13%, but in 2022 the volume of production in the region increased to 20.5 thousand tons. Absolute parameters in Stavropol Krai (11.8-12.3 thousand tons) Kabardino-Balkarian Republic (2.5-3.3 thousand tons) and Volgograd Oblast (2.3-2.5 thousand tons) remained almost unchanged. Significant growth of relative production parameters was noted in the Republic of Dagestan, the Republic of North Ossetia-Alania and the Republic of Crimea. The main objects of cultivation in the South of Russia are carp fish. A substantiation of creating a state-owned structure ensuring practical interaction between economic entities, executive bodies of state power, scientific and educational institutions is offered.

“…Water is one of the essential needs of humans, although it occupies two-thirds of the earth's surface, due to its time and space limitations on the one hand and the small amount of fresh and accessible water on the other hand, today it is necessary to manage and plan it. This subject is so important that some thinkers consider future human wars as water wars [1,2]. Special structures such as water tanks are of such importance that they must have high safety not only in normal and operating conditions but also in critical conditions such as earthquakes.…”

Liquid storage tanks are included in the group of industrial (non-building) structures, which are made of different types of steel and concrete and in different shapes, including cylindrical, cubic, conical, and spherical, on the ground and in the air, and with different uses, including liquid fuel storage tanks in Factories, oil and gas facilities, and the like, up to drinking water and firefighting tanks are divided into industrial towns and urban residential areas. Special structures such as water tanks are of such importance that they must have high safety not only in normal and operating conditions but also in critical conditions such as earthquakes. As a result, the design of these structures against seismic loads and their proper performance during an earthquake is very important. This study aimed to investigate and evaluate the seismic behavior of concrete tanks with fluid (water) in different states. For this purpose, 5 concrete tanks with different dimensions were investigated and parameters such as displacement, shear stress, soil settlement and displacement in a specific path were analyzed. By checking the displacement of these tanks, it was found that this parameter is the most optimal for tank number 4.

Despite the great interest in the use of probiotics to strengthen the immune characteristics of animals, there is not enough work on this issue, so we set ourselves the goal of studying the physiological state and immune status of sterlet grown in the ultrasound, which was fed with the addition of the probiotic “Enzimsporin”. A control group and three experimental groups were selected for the experiment, individuals were selected according to the principle of analogues of 50 in each group. For 60 days, the sterlet of the experimental groups was fed with the addition of probiotic in dosages of 1, 1.5 and 2 g/kg. Based on the combination of high linear-weight indicators and survival, we evaluated the hematological characteristics of individuals in the group that received a probiotic dosage of 1 g/kg of feed. In this experimental group, the number of erythrocytes and leukocytes in the blood did not significantly differ. When using a probiotic in a fish leukogram, the proportion of immature myeloid cells, including rod-shaped neutrophils, decreases from 3.1% to 0.6%. At the same time, there were no significant differences in the proportion of mature segmented neutrophils. The use of probiotics significantly increases the amount of lysosomal cationic protein in neutrophils to a value of 1.94 units of blood compared to the control group, whose values were 1.05 units, which indicates a favorable state of cellular immunity and a high immune status of fish in this group as a whole.
