One of the sources of omega-3 and omega-6 fatty acids, iodine, vitamins A, B, E, D, easily digestible protein is fish. In accordance with the order of the Ministry of Health of the Russian Federation dated August 19, 2016 "On approval of recommendations on rational consumption norms for food products that meet modern healthy eating requirements", the consumption of fish products is set at 22 kg per person per year. According to Alexander Saveliev, the head of the fishing information agency, fish consumption in Russia is around 12 kg per person per year. The low level of consumption is also confirmed by the National Financial Research Agency (NAFI), with only 36% of Russians eating fish once a week or more. Main fishing areas include the Far East, Arkhangelsk and Murmansk regions, Karelia. One of the key problems is delivering fish to all corners of the country, keeping it cold, either refrigerated or frozen, to prevent spoilage. Such methods reduce the taste quality of the fish. One solution is to increase the volume of fish farming in other regions of Russia to improve access to quality and fresh fish throughout the country. The second problem is the increase in the average annual temperature, leading to an oxygen deficit in water bodies that have lost the ability to self-recover. Considering the fragility of soil and water biocenoses, the low sum of active temperatures (SAT), the period of recovery for agrobiocenoses is a considerable period of time (more than 5 years). Our studies have shown that the main reason for the occurrence of fish kills in water bodies and low fish productivity is the slow rate of oxygen and carbon dioxide dissolution during the dark and light periods of the day. The BIOPRINTECH team has developed a device that improves aeration technology in aquaculture cultivation. Our value proposition is an energy-saving aerator for more efficient oxygen dissolution in water. The project is expected to develop into a comprehensive solution that will monitor and restore the entire water body biocenosis. The aerator is installed at the bottom of the water body, enriching the water with oxygen and maintaining the circulation of water layers. During experimental studies in a water body in the Sverdlovsk region, the speed of oxygen dissolution in water was significantly increased. Air dissolution rates increased by 3.7 times, and oxygen by 9.7 times. The implementation of: The proposed technology will allow to reduce specific energy costs from 336 to 92 rubles. The production effect results in a 2-3 times increase in the stocking density of aquaculture livestock without the use of additional territorial and water resources. Stable fish cultivation will increase the yield from 50 kg to 550 kg per 1 ha of water surface without compromising taste quality. The elimination of the need for annual stocking of fingerlings, artificial feeds, and mass fish kills in aquaculture will enhance the profitability of aquaculture cultivation.
