The correct steps for using the fish pond aeration fan
Fish pond aeration fan is a commonly used aeration equipment in aquaculture. Aeration is used in aquaculture, and the price of complete sets of equipment is not high. The one-time investment is not large, and it can save various disinfectants and antibiotics. It can also reduce water change, save fuel coal, and use ozone for seedling cultivation. Its survival rate can be more than doubled. Moreover, a set of equipment can be used for several years, which can greatly save breeding costs and cultivate green and environmentally friendly food. From all aspects, it is relatively economical.
A type of aeration and oxygenation machine mainly used in aquaculture and fisheries. Its main function is to increase the oxygen content in water to ensure that fish, shrimp, and crabs in the water do not lack oxygen, while also inhibiting the growth of anaerobic bacteria in the water, preventing the deterioration of the groundwater and threatening the living environment of fish. The high-pressure fan for fish pond oxygenation is generally supplied to aquaculture ponds by injecting air into the bottom of the water through its built-in air pump for oxygenation and aeration.
The correct steps for using the fish pond aeration fan:
1. Start the aerator for 1-2 hours on a sunny day at noon, fully utilizing its stirring effect to increase dissolved oxygen in the pond, accelerate material circulation, improve water quality, and reduce floating heads. Be sure to avoid starting the aerator in the evening on a sunny day, as it will cause early convection in the upper and lower water layers, increase oxygen consumption and water consumption, and easily cause fish floating heads;
2.On rainy days, the photosynthesis of phytoplankton is weak, and the dissolved oxygen in the pool water is insufficient, which can easily cause floating heads. At this moment, it is necessary to fully utilize the mechanical oxygenation effect of the aerator, and turn on the aerator early at night to directly improve the dissolved oxygen situation in the pool water, in order to prevent and rescue fish floating heads. It is necessary to avoid turning on the aerator at noon on rainy days, which not only fails to enhance the dissolved oxygen in the lower layer of water, but also increases the consumption of dissolved oxygen in the pond, which can easily cause fish floating heads
3.During the summer and autumn seasons, the water temperature is high during the day, the biological activity is high, and oxygen consumption is high. At dawn, it is generally advisable to turn on the machine appropriately to increase dissolved oxygen. If there is a sign of floating head, turn on the machine for emergency rescue and do not stop the machine until there are no fish on the water surface
4. When a large amount of fertilizer is applied and the water quality is too high, a combination of starting at noon and starting in the morning on sunny days should be used to improve the dissolved oxygen conditions in the pool water, prevent floating heads, and use aerators. In addition to being related to the weather, water temperature, and water quality mentioned above, the specific situation of fish farming should also be considered. Based on the changes in dissolved oxygen in the pool water, the starting method and time should be flexibly mastered to achieve reasonable use, increase efficiency, and yield.
In short, the principle of using an aerator is to turn it on at noon on sunny days, in the morning on cloudy days, in the middle of the night on continuous rainy days, in the evening, during the day on cloudy days, and in the morning on floating days; The weather is hot and the startup time is long, while the weather is cool and the startup time is short. The startup time is long at night and short at noon. The startup time is long when the load area is large, and short when the load area is small. Timely oxygenation is necessary。
