When is it best to turn on the aeration machine during the day?
What are the specific functions of the aeration machine in the fish pond?
Currently, most people engaged in aquaculture will install at least one aeration machine in the fish pond. It can be said that the aeration machine has become an indispensable agricultural machinery for fish farmers. Since it is an aeration machine, one of its functions is to increase oxygen in the water. This is also one of the three major functions of the aeration machine. Although fish live in water, they still need oxygen. When the oxygen content in the water is low, fish will float to the surface in large numbers. The aeration machine works by accelerating the flow of water through the impeller, which greatly increases the contact between water and air. The large amount of oxygen in the air will come into contact with the water and be dissolved into it, achieving the effect of oxygenation.
The aeration machine also has two other functions: aeration and temperature regulation. Since there are some aquatic plants and organisms in the water, during their metabolic processes, they will produce some harmful gases. The aeration machine, through the rotation of the impeller, causes waves on the water surface, which is conducive to the absorption of these harmful gases from the water and their release into the air. People call this process “aeration”. Moreover, after the aeration machine is turned on, it will stir the water body, which will keep the water temperature in the fish pond balanced and avoid excessive temperature differences between the upper and lower layers. This effect is particularly noticeable in summer.
When should the aeration machine be turned on in the fish pond?
When is it best to turn on the aeration machine in the fish pond?
Now that we understand the functions of the aeration machine, its main purpose is to increase the dissolved oxygen in the water body and improve the water quality, thereby reducing the occurrence of the “fish floating” phenomenon. Therefore, farmers should turn on the aeration machine at different times according to the weather.
On a sunny day, you should generally turn on the aeration machine at noon. Because during this period, the temperature difference between the upper and lower layers of the water is large, and the light is strong; the aquatic organisms in the lower layer have a strong respiratory process, so the oxygen content is low. Turning on the aeration machine in time supplements the oxygen in the water and accelerates the exchange of water bodies to avoid excessive temperature differences between the upper and lower layers.
On a cloudy day, it is generally better to turn on the aeration machine in the morning. At this time, the light is still weak, and the photosynthesis of some aquatic plants is weak, so the dissolved oxygen content is insufficient. Turning on the aeration machine in the early morning to increase oxygen in the water is to effectively avoid the crisis of fish “floating” due to insufficient oxygen.
During continuous rainy days, it is generally better to turn on the aeration machine at midnight. Because during long rainy days, aquatic plants in the fish pond photosynthesize poorly and produce far too little oxygen. Turning on the aeration machine at this time is to avoid fish death due to excessive water temperature differences.
In fact, there are certain rules for turning on the aeration machine. For example, it is not advisable to turn on the aeration machine in the evening when the sun is about to set, as it is likely to cause “fish floating” the next morning. As for the duration of turning on the aeration machine, it varies depending on the weather conditions. For example, the general time period for turning on the aeration machine at noon is a certain period, while the duration is longer at midnight; in hot weather, the duration should be longer, and in cool weather, it should be shorter; and in windy weather, the duration should be longer, while in strong wind conditions, it should be shorter.
