It is possible to increase the efficiency of pond farms by introducing new digital technologies into the technological processes of fish cultivation. Recirculating aquaculture systems serve a positive example of high technology applications in aquaculture. Automated control of all processes in pond fish farming starting from pond preparation for stocking of fish to placement and production of commercial fish will significantly increase the efficiency of fish farming by 70-80% thus increasing the overall profit by 20-30%. For properly organized feeding of fish it is necessary to take into account many factors, such as: fish-holding density, temperature of water and air, content of oxygen dissolved in water, ph-level of water and feed intake. The system of complex automation of any production enterprise shall be implemented taking into account the technologies of the fourth industrial revolution – Industry 4.0. The main unit of the system is an automated floating feeder with autonomous power supply from solar panels. The design and functional features of the feeder will determine the functionality of the entire automation system: automatic feeding, monitoring of water and environmental parameters, deoxidation of the water basin, supplementary feeding with insects, frightening of fish-eating birds. The innovative approach proposed by the authors is that if the pond is equipped with several floating feeders it is necessary to connect them to each other in a single information system, which functions through wireless radio communication. The assessment of the potential of the proposed modernization of a middle pond made it possible to increase the profit by 1.5 million rubles.

For intensive fish farming on fish farms, the food supply is a decisive condition. But the fodder base of reservoirs is not an unlimited resource, and compound feed is becoming more expensive and not always available. One of the solutions to this problem can be attracting flying insects to the surface of water bodies. Light traps of various models are increasingly used to attract insects at twilight and at night. The experiment used an experimental mobile electro-optical installation for the destruction of flying insects with an optical converter of the ultraviolet spectrum, a structure to which a high-frequency electric voltage is applied and a screen for collecting insects. The light trap attracts different species of insects, which also differ in their food value for fish. Nevertheless, natural food provides a good supplement with sufficient amounts of essential nutrients and energy. As a result of the obtained experiment, a species analysis of arthropods attracted by a light trap was carried out. The most active ones were representatives of the order Diptera, from the families of chironomids (bell mosquitoes) and midges (river midge). Representatives of the leafhopper family from the order of Hemiptera (bugs) also showed high activity. Chironomids are an important component of food for larvae and fry of fish, especially carp species. The proposed installation can operate in a mixed discrete mode, actively attracting flying insects without affecting them by high voltage, which contributes to the intensification of the development of food organisms.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
