The manufacturer of oxygenators explains that oxygenators are commonly used machines in fisheries and aquaculture. Their primary function is to increase the oxygen content in water, ensuring that fish do not suffer from oxygen deficiency. At the same time, they can also inhibit the growth of anaerobic bacteria in the water, preventing the pond water from deteriorating and safeguarding the fish’s living environment. Typically, oxygenators rely on their own air pumps to inject air into the water, thereby achieving the goal of boosting the oxygen level in the water.

Its primary function is to increase the oxygen content in water, ensuring that fish do not suffer from oxygen deprivation. At the same time, it can also inhibit the growth of anaerobic bacteria in the water, preventing the pond water from deteriorating and safeguarding the fish’s living environment. Typically, an aerator relies on its own air pump to inject air into the water, thereby achieving the goal of boosting the oxygen level in the water.

   Oxygenator Manufacturer Introduction An aerator is a device driven by an electric motor or diesel engine, among other power sources, that rapidly transfers “oxygen” from the air into the aquaculture water. It can comprehensively utilize physical, chemical, and biological functions, not only addressing the issue of fish surfacing due to oxygen deficiency in pond culture but also removing harmful gases, promoting convective exchange in the water body, improving water quality conditions, reducing feed conversion ratios, enhancing pond activity and primary productivity, thereby increasing stocking densities and boosting the feeding intake of cultured species.

  There are many types of oxygenators, each with its own unique characteristics and operating principles. The oxygenation 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.

   Oxygenator Manufacturer Introduction Aerator for Pond Improvement:

  The main effects are as follows: When oxygen levels in fish ponds drop, turning on an aerator can prevent fish and shrimp from "floating their heads." On sunny days, when dissolved oxygen levels are high in the upper water layers, enhanced water convection can increase dissolved oxygen concentrations in the middle and lower layers of the water body, promoting rapid growth of fish and shrimp, reducing feed conversion ratios, accelerating the oxidation and decomposition of organic matter, and thereby decreasing the incidence of diseases. Moreover, water circulation also facilitates the reproduction and growth of plankton, boosting the pond's primary productivity.

   The aerator manufacturer stated: The aerator not only increases the oxygen content in the water but also effectively enhances the pond’s primary productivity and self-purification capacity, thereby improving water quality and the ecological environment of the pond. Although the resulting water circulation may not be suitable for the living habits of certain aquaculture species such as eels and shrimp, it significantly promotes the healthy and rapid growth of fish and shrimp.

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.
