When the oxygen in the pond is insufficient, the fish pond aerator can be turned on to prevent the fish and shrimp from "floating". The fish pond aerator can accelerate the convection of the water body, increase the oxygen in the lower layer of the water body, reduce the rapid growth of fish and shrimp, and promote the oxidation of organic matter. decompose and reduce the occurrence of diseases; in addition, the water cycle promotes the reproduction of plankton and improves the primary productivity of fish ponds.

1. It starts at 2-3 pm on a sunny day. At this time, the surface temperature above 1 meter is high, the light is sufficient, the photosynthesis is strong, and the amount of dissolved oxygen reaches supersaturation. After the power is turned on, the dissolved oxygen on the surface is mixed with other water layers. In the water layer below 1 meter, the light becomes darker, the temperature decreases, the photosynthesis becomes weaker and weaker, and the dissolved oxygen becomes less and less. At this time, start the aerator, Mix the water, break the thermal layer, promote the convection exchange between the upper and lower water in the pool, fill the oxygen flow of the lower water, and reasonably maintain the entire water area. The start-up time depends on the load of the aerator, for example: 3KW oxygen generator, sleep 3~5 times in 30 minutes, if the load is 6-10 mu of sleep, please turn it on for 1 hour. The oxygen balance will fill up, and at the same time, the dissolved oxygen storage in the pond water will increase. Generally, it won't ignite the next morning.

2. The situation will light up when it is cloudy. Generally, on cloudy days, choose to turn on the next morning, the purpose is to directly increase oxygen by paddling. Due to the weak photosynthesis on cloudy days, the water-soluble oxygen reserve in the pond is less, and the consumption at night will cause the water-soluble oxygen in the pond to drop to near the oxygen threshold of the fish. Therefore, the machine should be turned on at 3-5 in the morning to shorten the concentration of water and fish killing. running time.

When the rainy season continues or there is serious danger to the dock such as water, fatty fish, and wheat, the machine should be turned on before the fish float. Specifically, the wild fish in the pond will light up when there are traces of shrimp floating, usually around midnight. At this time, the oxygen content of the pond is very low, and it cannot be rescued until the farmed fish are opened again, and the fish can easily die in the flooded pond. The oxygen threshold of wild fish and shrimp is lower than that of farmed fish, which is used as a reference for the start-up period.

It does not turn on during the day in the rainy season. In the rainy season, photosynthesis is weak, and the surface water-soluble oxygen is not oversaturated. At this time, when the machine is turned on, the surface water will mix the supersaturated dissolved oxygen on the floor, which cannot achieve the purpose of increasing oxygen.

3. Do not turn on the ventilator in the fish pond at night to promote the early convective mixing in the sewer area of ​​the fishery and increase the oxygen consumption rate. If the water quality deteriorates, it must be started, do not stop the work, and prepare to use stimulants at the same time. It can be noticed that the function of the fish pond aerator is not only to increase the oxygen in the water, but also to improve the primary productivity and self-production capacity of the fish pond. But it can promote the healthy and rapid growth of fish and shrimp.
