An aerator is a device that drives working parts through a power source such as an electric motor or a diesel engine to quickly transfer the "oxygen" in the air to the aquaculture water body. It can make comprehensive use of physical, chemical and biological functions. It can not only solve the problem of fish head floating caused by lack of oxygen in pond aquaculture, but also eliminate harmful gases, promote convective exchange of water bodies, improve water quality conditions, reduce feeding coefficients, increase fish pond activity and primary productivity, thereby increasing stocking density , Increase the breeding intensity of the breeding objects, promote the growth, greatly increase the yield per mu, and fully achieve the purpose of increasing the breeding income.
What are the main manifestations of the improvement effect of the aerator on the pond: When the fish pond is deprived of oxygen, turning on the aerator can prevent the "floating head" of fish and shrimp. When the dissolved oxygen in the upper layer is high on a sunny day, the activation can accelerate the convection of the water body, improve the dissolved oxygen in the middle and lower layers of the water body, facilitate the rapid growth of fish and shrimp, reduce the feed coefficient; promote the oxidation and decomposition of organic matter, and reduce the occurrence of diseases. In addition, the circulating water flow also promotes the reproduction and growth of plankton, and improves the primary productivity of the pond. It can be seen that the role of the aerator is not only to oxygenate the water body, but also to effectively promote the improvement of the primary productivity and self-purification capacity of the pond, thereby improving the water quality and ecological environment of the pond. The water circulation flow produced by it is not suitable for the living habits of eels, shrimps and other cultured objects, but it has played a good role in promoting the healthy and rapid growth of fish and shrimps.
China's aquaculture is gradually developing towards high density and intensification, and the total aquaculture output is increasing year by year. This is inseparable from the gradual mechanization of aquaculture, especially the widespread use of aerators. It can be said that the fish and shrimp aerator is the basic equipment necessary for the modernization of our country's fishery.
