Aerator supplier: An aquaculture aerator is a device that uses a power source—such as an electric motor or diesel engine—to drive working components, enabling rapid transfer of “oxygen” from the air into the aquaculture water. It integrates physical, chemical, and biological functions to address both the issue of fish floating due to oxygen deficiency in pond culture and the accumulation of harmful gases. By promoting water convection and exchange, it improves water quality conditions, reduces feed conversion ratios, enhances the activity and primary productivity of fish ponds, thereby increasing stocking densities, intensifying fish feeding rates, accelerating fish growth, significantly boosting per-mu yields, and fully achieving the goal of increasing farm income.

　　Aerator supplier: An aquaculture pond aerator is a device that uses a power source—such as an electric motor or diesel engine—to drive working components, enabling rapid transfer of “oxygen” from the air into the aquaculture water. It integrates physical, chemical, and biological functions to address both the issue of fish floating due to oxygen deficiency in pond culture and the accumulation of harmful gases. By promoting convective exchange in the water body, it improves water quality conditions, reduces feed conversion ratios, enhances pond activity and primary productivity, thereby increasing stocking density, intensifying fish feeding behavior, accelerating fish growth, significantly boosting per-acre yields, and fully achieving the goal of increased aquaculture income.

　　 Proper Use of Fish Pond Aerators:

　　1. Start working between 2 and 3 p.m. on a sunny day. At this time, the surface water layer—more than 1 meter deep—is relatively warm, receives ample sunlight, exhibits strong photosynthetic activity, and reaches supersaturated levels of dissolved oxygen. Once the aerator is turned on, it mixes the dissolved oxygen from the surface layer with that of other water layers. As daylight gradually dims and air temperature drops, photosynthesis weakens, leading to a gradual decrease in dissolved oxygen. Meanwhile, the lower layers may develop an oxygen deficit. At this point, activating the pond aerator to stir the water can break up the thermal stratification, promoting convective exchange between the upper and lower layers of the pond, thereby replenishing the oxygen deficit in the bottom layer and maintaining a reasonable dissolved-oxygen level throughout the entire water body. The duration of operation should be determined based on the surface area covered by the aerator’s load. For example: a 3-kilowatt aerator covering 3–5 mu of water should run for half an hour; a 6–10-mu pond requires an hour of operation. After starting work for a certain period in the afternoon at 4 p.m. on a sunny day, once the lower layers have been fully replenished with oxygen and the pond’s dissolved-oxygen storage has increased, the aerator generally won’t need to be kept running into the next morning.

　　2. Oxygenator Supplier: Turn on the oxygenator on cloudy days. Under normal circumstances, it’s generally advisable to start the oxygenator early the next morning on cloudy days. The purpose of doing so is to directly mix and aerate the water. Since the dissolved oxygen reserves in pond water are relatively low, photosynthesis weakens on cloudy days, and after overnight consumption, the dissolved oxygen level in the pond water may drop close to the oxygen threshold for fish. Therefore, the oxygenator should be turned on between 3:00 a.m. and 5:00 a.m. If the water is rich in nutrients and the fish population is dense, the oxygenator should be started even earlier.

　　When fish begin to float to the water’s surface, prolonged rainy weather or insufficient water fertility can both pose a serious risk of fish surfacing. Specifically, when wild雜fish and small shrimp in the pond show signs of surfacing, it’s time to start aerating—typically around midnight. At this time, the oxygen content in the pond water is extremely low. If we wait until the cultured fish themselves start surfacing before turning on the aerator, it may be too late to save them, easily leading to mass fish mortality. Wild雜fish and small shrimp have lower oxygen thresholds than cultured fish, making their behavior a useful indicator for determining when to start aeration. During rainfall, even if it isn’t raining during the day, photosynthesis is weaker on sunny or partly cloudy days, preventing the water from becoming oversaturated with dissolved oxygen. As a result, any excess dissolved oxygen at this stage cannot sink to the bottom of the pond, thus failing to achieve the intended purpose of oxygen enrichment.

　　3. Oxygenator Supplier: Under normal weather conditions, the dissolved oxygen level in the pond is usually sufficient at night; therefore, do not operate the fishpond oxygenator at night. If you do turn it on, it may cause the upper and lower water layers of the pond to mix prematurely, accelerating the rate of oxygen consumption. If the water quality deteriorates, you must immediately stop operating the oxygenator and simultaneously prepare an oxygenating agent for use in conjunction with it.
