Aquatic breeding will be affected by water quality, temperature, pressure, area, water depth, oxygen, etc. Among them, oxygen has the greatest impact. If you are not careful, you may form a floating head of aquatic organisms and die. In addition to adding oxygen, the aeration fan can also promote the flow of water and avoid the temperature stratification of the water body. Together with chemical stratification and oxygen stratification, the aerator must operate deep in the pond to improve the bottom of the pond. The soil quality can increase the oxygen of the subsoil and avoid the occurrence of harmful gases to effectively avoid the possibility of disease and death of aquatic animals.
The relationship between the aeration and oxygenation time of fish ponds and the climate and temperature seasons. Turn on at noon on a sunny day. At this time, the temperature of the upper and lower water layers in the fish pond is different, and the oxygen in the grassroots water cannot be compensated in time. When the aerator is opened, the upper grassroots water can communicate. The temperature difference and oxygen difference are greatly reduced, and the oxygen in the grassroots water can be compensated in time.
Turning on in the cloudy early morning At this moment, the intensity of sunlight is weak, the photosynthesis of phytoplankton in the fish pond produces less oxygen, and the dissolved oxygen in all water bodies is poor. Therefore, starting the aerator in the early morning when the dissolved oxygen point is low can deal with the "fish floating head" crisis caused by the lack of oxygen in the water before and after dawn.
Continuous rain and late night boot In the continuous rainy weather, because of the long period of time and lack of sunshine, the photosynthesis of phytoplankton in the fish pond produces very little oxygen. It is necessary to start the machine to increase oxygen late at night to avoid the death of fish in the pond.
At dusk, when the sun sets, the photosynthesis of phytoplankton in the fish pond is about to cease, and oxygen can no longer be supplied to the water. If it is turned on at this moment, the dissolved oxygen in the upper water will be reduced and cannot be compensated. Dissolved oxygen in the grassroots water will be quickly consumed, speeding up the rate of oxygen consumption, and the "fish floating head" will appear more simply the next morning.
In addition, the length of time to turn on the aerator is also very elegant: the time to turn on in hot weather is long, and the time to turn on in cool weather is short; the time to turn on late at night is long, and the time to turn on at noon is short; the time to turn on after fattening should be long, and the time when not fattening should be short. ; The start time should be long when the wind is small, and short when the wind is strong.
