Oxygenator manufacturers point out that aquaculture experts and technical personnel both domestically and internationally have reached a consensus: by combining superior breeding of healthy fry, comprehensive management of the aquaculture environment, feeding with high-efficiency, high-quality feed, and scientifically sound disease prevention and control measures, we can establish a pollution-free, healthy aquaculture system. In our region, shrimp and crab farming is being actively promoted, and aquaculture technologies are continuously being refined and updated. Aquaculture models have evolved from semi-intensive to intensive farming, and oxygenators serve as the primary foundation for intensive aquaculture. Therefore, it is especially important to use oxygenators during the hot summer months.

　　 Aerator manufacturer It was stated that aquaculture experts and technical personnel from both home and abroad have reached a consensus: by combining advanced breeding techniques for healthy fish fry, comprehensive management of the aquaculture environment, feeding with high-efficiency, high-quality feed, and scientifically sound disease prevention and control measures, we can establish a pollution-free, healthy aquaculture system. In our region, shrimp and crab farming is being actively promoted, and aquaculture technologies are continuously being refined and updated. Aquaculture models have evolved from semi-intensive to intensive farming, and oxygenators are the key foundation of intensive aquaculture. Therefore, during the hot summer months, it is essential to use oxygenators.

　　1. During sunny noons in the hot summer months, especially in aquaculture ponds with fertile water and abundant phytoplankton, aerators should be turned on for 2-3 hours. On hot, sunny days, phytoplankton photosynthesis is particularly vigorous, releasing large amounts of oxygen into the water. In aquaculture ponds with rich water quality, where water transparency reaches 20-30 centimeters, the middle layer of the water lacks sunlight and thus exhibits weaker photosynthesis. Since aerators have the function of lifting water upward, turning them on can create a vertical circulation within the aquaculture pond.

　　2. During the day, the sunlight is intense and the water temperature is high. However, in the evening, sudden thunderstorms bring large amounts of cool rainwater into the aquaculture ponds, causing the surface water temperature to drop sharply. As a result, the surface water becomes lighter and sinks rapidly, while the deeper water, being warmer and denser, rises upward. The oxygen-rich water from the upper layer is then transferred to the lower layer, temporarily boosting the dissolved oxygen levels there. Yet, this increase is quickly consumed, leading to a rapid decline in dissolved oxygen throughout the entire pond—thus making it easy for fish to float toward the surface. Therefore, it’s crucial to promptly turn on the aeration equipment. Special note: It’s generally not advisable to start paddle-wheel aerators in the evening, because at this time, photosynthesis by phytoplankton comes to a halt, leaving them unable to replenish oxygen in the water. Once the aerator is started, the dissolved oxygen distribution between the upper and lower layers becomes uniform. As the dissolved oxygen in the upper layer decreases, it can no longer be replenished; meanwhile, the dissolved oxygen in the lower layer is rapidly depleted, accelerating the overall consumption of dissolved oxygen in the entire aquaculture pond.

　　3. In summer, if there are consecutive rainy days, photosynthesis by phytoplankton will be weaker, leading to lower dissolved oxygen levels in the water and potentially causing oxygen deficiency. This can easily result in fish surfacing for air. Therefore, more aerators should be turned on.

　　What are the functions of an aeration machine for fish ponds? Let an aeration machine manufacturer guide you to learn more.

　　Although fish live in water, they still need oxygen. When the oxygen content in the water is low, fish tend to float their heads more frequently. Aeration machines for fish ponds use impellers to accelerate water flow, greatly increasing the contact between water and air. As a result, abundant oxygen from the air comes into contact with the water and dissolves into it, achieving an aeration effect.

　　In addition, the aerator has two functions: aeration and water temperature regulation.

　　Because some aquatic plants and organisms live in the water, they produce certain harmful gases during their metabolic processes. The aerator stirs the water surface by rotating its impeller, which is beneficial to the water. As a result, harmful gases such as hydrogen sulfide, ammonia, methane, and sulfur dioxide are desorbed from the water and released into the air. This process is called aeration.

　　Moreover, once the aeration machine in the fish pond is started, it stirs the water, helping to maintain a balanced water temperature and preventing excessive temperature differences between the upper and lower layers—this is especially effective during summer.
