When the weather is clear, the aerator should be turned on at noon. In hot summer and autumn, the photosynthesis of plankton in the aquaculture pond is particularly strong at noon. The transparency of the water body is around 20 to 30 centimeters, and photosynthesis is weaker in deeper parts of the water
The aerator can lift water upwards for two to three hours, thereby forming a vertical circulation in the breeding pool. It can be turned on in the middle of the night for two consecutive cloudy days. Continuous rainy weather weakens the photosynthesis of plankton in the aquaculture pond, resulting in low oxygen production. In addition, the low air pressure during rainy weather leads to high consumption of aquaculture products, causing them to start floating in the middle of the night. At this time, turning on the aerator can increase dissolved oxygen in the water. Thus alleviating the floating phenomenon.
Turn on the machine two hours before and after feeding the ingredients. The purpose of turning on during this time period is to utilize the function of the aerator to create a circulating flow of water. In this way, the taste of the feed can be carried to various parts of the breeding pool, thereby causing the feeding of the livestock.
On the sunny day, clear the scenery and turn on the machine. Tomorrow, the light is poor, the oxygen production of plankton is relatively low, and the oxygen treatment in the breeding pool is relatively low. By the morning of the next day, the oxygen supply in the breeding area may be insufficient. At this time, turning on the aerator can increase the oxygen in the pool and avoid the low peak period of dissolved oxygen.
The three no open principles for using aerators:
Not turning on after sunrise in the morning. At this time, the light is strong, the photosynthesis of plankton in the pool is strong, and the dissolved oxygen is sufficient. There is no need to turn on the aerator. On rainy days, the machine does not turn on at noon. At this time, the light is insufficient, the photosynthesis of plankton is weak, and the dissolved oxygen in the surface is not in a supersaturated state. Opening the oxygenation opportunity at this time reduces the oxygen production capacity of the upper layer of plankton and accelerates the oxygen consumption rate of the lower layer, which in turn increases the dissolved oxygen consumption rate in the aquaculture pond and is more likely to cause floating heads.
Not turning on in the evening. The oxygen content in the oil bath is not low, there is no need to turn on the fish pond aerator. On the contrary, if the aerator is turned on at this time, it will actually cause early convection of the water in the pond, resulting in a very low peak of oxygen content in the oil during the ice layer, which is more likely to cause floating heads.
