Efficiency of attraction of mosquitoes by the electrooptical converter to feed the fish

Intensive fish farming in inland waters is associated with the use of artificial feed, which is not always balanced in nutrients. To obtain high fish productivity of ponds, it is necessary to increase the proportion of live feed, natural food resources of ponds and reservoirs in the diet of fish feeding with the use of local feed resources. To this end, electro-optical converters are used to attract mosquitoes. These electrical installations are located above the water surface, in places accessible to fish and are used in conjunction with platforms for swarming mosquitoes. The platform creates favorable conditions for laying eggs by insects. The larvae spitting out of them become food for fish. The number of mosquitoes attracted by electro-optical transducers, hence their efficiency, depends on the color of the optical radiation of the attractant lamps. It was found that the optimal chromaticity coordinates of the radiation attracting mosquitoes vary from the ambient temperature. The article describes two LED electrical installations for attracting mosquitoes by optical radiation. The first of them is tuned to a certain optimal color of the radiation. The chromaticity coordinates of the RGB LEDs in the second electro-optical converter vary depending on the ambient temperature, which allows to increase the efficiency of attracting mosquitoes.
