How to correctly use the fish pond aerator in the aquaculture pond:

At present, aquaculture experts and aquaculture technicians at home and abroad have reached an agreement to establish a pollution-free and healthy aquaculture system through a combination of technologies such as excellent cultivation of healthy seedlings, comprehensive control of aquaculture environment, feeding high-efficiency and high-quality feed and prevention of scientific diseases. The breeding technology is constantly improved and updated. The breeding mode has developed from semi intensive breeding to intensive breeding. On the main basis of intensive breeding mode, it is inseparable from the aerator. When the aerator is used at high temperature in summer, pay attention to the following points:

1. On sunny days with high temperature in summer, at noon, especially in aquaculture ponds with fertile water quality and abundant phytoplankton, it is necessary to turn on the aerator for 2 ~ 3 hours. Because the photosynthesis of phytoplankton is particularly strong on hot and sunny days, it will release a lot of oxygen to the water body. However, in the aquaculture pond with relatively fat water quality, the transparency of water is 20 ~ 30 cm, there is no light in the middle layer of water, and the photosynthesis is very weak. The aerator has the function of lifting water upward. When it is started, it can form a vertical circulation of the breeding pond.

2. There is sunlight during the day and the temperature is high. There is a thunderstorm at night. The rain with low temperature enters the breeding pond. The surface water temperature drops sharply and the specific gravity drops rapidly. The specific gravity of the lower water rises because of the high temperature. The water with high dissolved oxygen in the upper layer is transmitted to the lower layer, which temporarily increases the amount of water-soluble oxygen in the lower layer, but it is quickly consumed, resulting in a rapid decline in the dissolved oxygen in the whole pond, which is easy to cause fish floating head. The aerator should be opened in time. Special attention should not be paid to turning on the impeller type aerator in the evening, because the photosynthesis of phytoplankton is interrupted and oxygen cannot be increased in the water. After power on, the dissolved oxygen in the upper and lower water is evenly distributed. The dissolved oxygen in the upper layer is not supplemented after it is reduced, and the dissolved oxygen in the lower layer is consumed rapidly, which speeds up the consumption of dissolved oxygen in the whole aquaculture pond.

3. Continuous rainfall in summer, weak photosynthesis of phytoplankton and less dissolved oxygen supply in water are likely to cause insufficient dissolved oxygen. Therefore, more aerators should be opened.

4. In the long-term sunny and rainless weather, the water temperature of the breeding pond is high, a large number of aquatic products are fed and excreted, the water quality is too fat, the transparency is reduced, there is more organic matter in the water, the upper and lower dissolved oxygen cross, and the "oxygen debt" in the lower layer is large. If new water is not injected for a long time, the water quality may be damaged and the oxygen of aquatic products is insufficient. At this time, more aerators should be opened.

5. In summer, aquaculture ponds often lack oxygen due to overcrowding of aquatic products and oxygen consumption of other organisms, resulting in local or pond aquatic products floating. Therefore, turn on the aerator at 1 ~ 2 p.m. and the sun comes out at 7 ~ 8 a.m. the next day. Phytoplankton can smoothly produce photosynthetic oxygen until they don't float.

6. Turn on the aerator 1 ~ 2 hours before and after feeding the feed. The aerator can stir the water in the breeding pond to form a circular flow. On the one hand, it can bring the feed taste to all parts of the breeding pond and play a role of food attraction. On the other hand, it can also form a conditioned reflex habit of feeding aquatic products.
