Designing and upgrading the installation for the Don vimba (Vimba vimba) cultivation

In Russia, in order to transition to highly productive and environmentally friendly agro- and aquatic farming, to create safe and high-quality, including functional, food products, it is necessary to focus on the introduction of new facilities available to consumers into aquaculture. The relevance of the chosen direction lies in the intro-duction of the Don fish into aquaculture in the Southern Federal District and the southern regions of the Russian Federation. Global aquaculture is actively developing. The volume of industrial fishing products in 2023 amounted to 89.6 million tons. At the same time, in recent years, fish catches ranged from 110 to 590 tons, and the average annual production in the Azov-Don region reached 270 tons. Catches are decreasing annually, which leads to the need to increase the production of aquaculture facilities. The main objectives of the research are to develop the design of a plant for growing Don fish (Vimba vimba) and conduct research on the content of producers. Experiments have been carried out on the cultivation of young Don fish on granular feed in an upgraded installation. The experiments were carried out in two versions: on water from an open source of water supply prepared using a water treatment unit, and on tap water. Conducting weekly hydrochemical analyses of water and biological material in experimental installations for the maintenance of producers and the rearing of juveniles made it possible to determine the optimal indicators for the maintenance of producers, spawning, holding and rearing of larvae.
