The correct use of the aerator can not only greatly red […]
The correct use of the aerator can not only greatly reduce its operating costs, but also effectively improve the water quality of the fish pond and reduce or avoid the occurrence of fish diseases. At the same time, it can effectively reduce the feed coefficient of the feed and increase the profitability of breeding. Many fish farmers do not understand the oxygenation principle of the aerator, and improper use of the method will not only fail to achieve the effect of aeration, but also cause serious consequences of hypoxia in the fish pond.
1. No power on during the day, long time at night
Many farmers think that the daily fish pond is not deprived of oxygen and does not need to be turned on. They only realize the effect of mechanical oxygenation and ignore the most important biological oxygenation effect. And making good use of biological aeration can often save a lot of costs because of greatly reducing the time to open the aerator.
2. Open the aerator on rainy days
Many farmers think that the fish pond lacks oxygen in rainy days and should use aerators. In fact, this is a very wrong boot method. The correct way is to prohibit turning on during the rainy day. Although the photosynthetic effect is poor in the rainy day, the aeration effect is still much stronger than the mechanical aeration effect. This little oxygen should be stored on the surface of the fish pond so that the fish can use it at night. If it is turned on in a cloudy and rainy day, the only bit of dissolved oxygen is stirred to the bottom of the pool to be used by organic matter, and the dissolved oxygen in the pool water at night cannot be replenished satisfactorily, and it is easy to form hypoxia.
3. Turn on the aerator on a sunny day at 4 a.m. and after 4 p.m.
In some sunny mornings, the aerator is also turned on, thinking that this will increase oxygen. In fact, this is also the wrong way to start. Since the mechanical oxygenation effect of the aerator is far lower than that of biological oxygenation, if the fish leaves the aerator in the morning, it should be shut down immediately. Some farmers thought that the stocking density of fish ponds was high and the water quality was not good, so they turned on the aerator when it was dark. In fact, as long as the fish pond is not close to hypoxia from 4 pm to night, there is no need to start the machine, because the time of opening at this moment will consume the molten oxygen on the surface of the pool water in advance and accelerate the night's hypoxia.
4. Not booting on a sunny day and windy
Some farmers think that the wind has the effect of increasing oxygen, and it can be turned off at noon on a sunny day. In fact, this is not entirely accurate. The wind has the aerobic effect, but the convection effect on the pool water is not strong. The surface oxygen-enriched pool water is difficult to convection to the bottom of the pool. Only when the temperature drops suddenly, the drop in surface water temperature can make the surface pool water useful convection to the bottom. Therefore, in addition to this situation, the machine should be switched on at noon on a sunny day, whether there is wind or not.
5. In the first half of the year, the fish pond does not float and the head does not start
Many farmers think that the water temperature is low from April to June, the fish body is small, and the head cannot be turned on without floating. In fact, when the fish eats a lot, defecates a lot, and the water quality is fat, they should be turned on at noon on a sunny day. This can delay the season of fish floating heads and reduce the degree of floating heads. Together, the pool water can be fertilized in advance and the deterioration of water quality can be delayed.
