An oxygen-injecting machine for agricultural use is a device that rapidly transfers “oxygen” from the air into aquaculture waters by driving its main working components via power sources such as electric motors and diesel engines. It enhances the integrated utilization of physical, chemical, and biological technologies. Not only does it address fish mortality caused by oxygen deficiency in pond aquaculture, but it also helps eliminate harmful gases, promotes convective exchange in water bodies, improves water quality conditions, and reduces—or even increases—the feed conversion ratio.

An oxygen-increasing machine subsidized by agricultural programs is a device that can be frequently used in China's fishery and aquaculture industries. Its primary function is to increase the oxygen content in water, ensuring that fish are not deprived of oxygen, inhibiting the growth of anaerobic bacteria in the water, and preventing pond deterioration that could threaten the fish's living environment. Typically, these oxygen-increasing machines use their own air pumps to introduce atmospheric air into the water, thereby increasing the oxygen concentration in the water to meet operational needs.

The agricultural subsidies for aerators primarily highlight that, when fish ponds experience oxygen deficiency, turning on the aerator can prevent fish and shrimp from exhibiting “floating heads.” On sunny days, when dissolved oxygen levels in the upper water layer are high, operating the aerator helps accelerate water circulation in China’s aquatic systems, boosting dissolved oxygen levels in the lower layers of urban water bodies. This, in turn, promotes rapid growth of fish and shrimp, reduces feed conversion ratios, and facilitates the decomposition of organic matter through oxidation processes, thereby minimizing the occurrence of disease outbreaks. Moreover, the cyclical flow of water fosters the reproduction and growth of phytoplankton, enhancing the primary productivity of public ponds.

　　As can be seen, research on the function of oxygen-increasing machines not only helps boost oxygen levels in aquatic bodies but also effectively manages and improves pond water quality and the ecological-economic environment by promoting the enhancement of primary productivity and self-purification capacity in ponds. Although its water circulation and flow may not be suitable for certain aquaculture species—such as eels and shrimp—this technology plays a significant role in fostering the healthy and rapid growth of fish and shrimp in China.

　　Composition of shrimp farms

　　The composition and amount of agricultural subsidies for aerators primarily depend on factors such as water source conditions, stocking density, and the total energy consumption associated with inflow and drainage.

Water: Water is abundant, and water quality is good.

　　Stocking density determines yield per mu. Higher stocking density means higher yield, while lower stocking density means lower yield.

　　Drainage energy consumption: If the energy consumption for drainage is low, fewer ancillary equipment may be required for the oxygen-producing machine. Conversely, if energy resource consumption is high, the scale of the equipment needed will be larger.

　　Economic Analysis: Consider electricity costs and shrimp price ratios. For example, if local electricity costs are relatively high and shrimp prices are relatively low, consider reducing the allocation. Conversely, increase the allocation.

　　What are the application prospects of oxygen generators in agricultural subsidies?

China is one of the world’s leading fisheries producers, and for nearly two decades, its fishery output has consistently ranked among the highest globally. The total value of China’s domestic fisheries accounts for 10% of the country’s total agricultural output. Chinese-style aquaculture technologies have gradually evolved toward higher-density and intensive management practices. As a result, total aquaculture production has been increasing year by year, closely linked to the ongoing mechanization of the aquaculture industry—particularly the widespread research and use of yield-increasing machinery. Yield-increasing machinery can be regarded as an indispensable piece of foundational equipment for China’s drive toward the modernization of its fisheries sector.

　　We encourage and support oxygen-increasing machine manufacturers and agricultural machinery enterprises in developing new products, including advanced production equipment that features timed productivity enhancement, automated information protection and management control, and intelligent networked control systems. These innovations aim to reduce the heavy physical labor burden on fishermen, maximize the practical performance and reliability of oxygen-increasing machines, promptly address water quality and environmental pollution, cut electricity costs, and enhance the economic and social benefits for fishermen. Through several years of dedicated efforts, China’s oxygen-machine manufacturers have managed to carve out a significant position in the international market.
