Oxygenator manufacturers point out that there are many types of oxygenators, each with its own unique characteristics and operating principles. The oxygenation effects vary considerably, and so do their respective application ranges. Producers can select the appropriate oxygenator based on the dissolved oxygen requirements of different aquaculture systems, thereby achieving optimal economic efficiency.

　　 Aerator manufacturer indicates Aerator There are many types of products, each with its own unique characteristics and operating principles. The oxygen-increasing effects vary considerably, as do their respective application ranges. Producers can select the appropriate oxygenator based on the dissolved-oxygen requirements of different aquaculture systems, thereby achieving optimal economic efficiency.

　　 Aerator Manufacturer's Explanation Classification of aerators:

　　Impeller-type aerator

　　It features integrated functions of oxygenation, water mixing, and air bubbling. Currently, it is one of the most widely used aeration devices, with an annual output of approximately 150,000 units. Its oxygenation capacity and power efficiency are superior to those of other models, though it generates relatively high operating noise. It is typically used in large-scale pond aquaculture where the water depth exceeds 1 meter.

　　Waterwheel aerator

　　It has excellent oxygenation and water-flow promotion effects, making it suitable for ponds with relatively deep silt and an area ranging from 1,000 to 2,540 m².

　　Jet-type aerator

　　Its oxygenation power efficiency surpasses that of paddle-wheel, aeration, and spray-type aerators. It features a simple structure that can create water flow and stir the water body. It gently warms and oxygenates the water without harming fish, making it ideal for oxygenating fish fry ponds.

　　Water-spraying oxygen-increasing model

　　It features excellent oxygenation capabilities, enabling a rapid increase in dissolved oxygen levels in surface water bodies within a short period. It also offers aesthetic appeal and is ideally suited for use in fish ponds located in gardens or tourist areas.

　　Inflatable aerator

　　The deeper the water, the better the effect. Suitable for deep water.

　　Suction oxygenator

　　Air is drawn into the water by negative pressure suction, mixes with the water to form a vortex that propels the water forward, resulting in strong mixing action. Its ability to oxygenate the lower layer of water is superior to that of impeller-type aerators, while its ability to oxygenate the upper layer is slightly less than that of impeller-type aerators.

　　Vortex Oxygenator

　　Primarily used for oxygenating subglacial water in northern regions, with high oxygenation efficiency.

　　Oxygen pump

　　Due to its light weight, ease of operation, and single oxygen-increasing function, it is generally suitable for use in fish fry ponds or greenhouse aquaculture ponds with a water depth of no more than 0.7 meters and an area of no more than 0.6 mu.

　　 The aerator manufacturer stated: With the continuous refinement of fishery demands and the ongoing improvement of aeration technology, many new types of aerators have emerged, such as surge-type aerators and spray-type aerators.

The China International Fisheries Expo is one of the world’s largest and most influential international trade fairs in the global aquaculture industry, having served the global aquaculture sector for 25 years. Since its inception in 1996, the expo has effectively integrated diverse, global, end-to-end industry resources—from aquatic product trading and related technologies and processing to cold-chain logistics, food and ingredients, catering and hospitality, as well as consulting and investment—into the Chinese market.

The relationship between water convection and dissolved oxygen levels in aquatic bodies: The introduction of an aeration device can effectively regulate dissolved oxygen levels.

Although fish floating to the surface can be caused by a variety of factors, in addition to excessive stocking density, overloading the total fish biomass, and poor water quality, the convective properties of water are also a major factor that cannot be overlooked. Simply put, when water temperature is low, its specific gravity (or density) increases, causing it to sink; conversely, when water temperature is high, its specific gravity (or density) decreases, making it float upward. Understanding and mastering the principles of water convection will greatly facilitate the smooth operation of aquaculture. On warm days, after being heated by the sun during the day, the warmer, lighter water tends to stay on top. As the sun sets and the air temperature begins to drop, the upper layer of water cools down, increasing its density, and gradually starts to sink. If the nighttime temperature remains relatively high, the water cools down slowly, and the upper layer won't reach the bottom of the pond until early morning. This is one of the main reasons why oxygen levels tend to drop sharply from late night into early morning on hot days. However, if a heavy rainstorm occurs in the evening, the situation changes dramatically. The cold, heavy rainwater quickly sinks to the bottom of the pond, stirring up sediment, leftover feed, fecal waste, biological residues, and other organic matter from the pond bottom and bringing them into the middle and upper layers of the water. These harmful organic substances rapidly deplete the dissolved oxygen in the water. Before dawn even breaks, the dissolved oxygen in the water may be completely used up, leaving the fish vulnerable to oxygen depletion and causing them to float to the surface—a phenomenon known as "floating and surfacing." Therefore, sudden heavy rainfall in the evening or at night can also lead to oxygen depletion and fish floating to the surface.

How to choose an aerator?

Oxygenators are used to increase the oxygen content of water bodies. There are many types of oxygenators available, including impeller-type, paddle-wheel type, aeration-type, air-injection type, spray-type, and jet-type oxygenators. Oxygenation helps save fish and ensures high yields. According to measurements, each ten-million-unit impeller-type oxygenator can add more than 1.8 kilograms of oxygen to the water per hour—enough to meet the respiratory needs of several tons of fish for an entire hour—and can promptly address oxygen deficiency in pond fish. After using oxygenators, the production conditions of fish ponds have shifted from natural ecosystems to artificially controlled ecosystems, thereby breaking through the limitations on fish yield imposed by still-water ponds under natural conditions.
