Winter shed shrimp to use aerator properly
The shrimp in the winter shed is prone to lack of oxygen, especially from 4am to 7am. Therefore, the time for opening the aerator should be every night. In addition, it should be turned on in the middle and late stages of breeding, as well as on rainy and cloudy days. At noon, there is plenty of sunshine and strong photosynthesis. It is generally not easy to lack oxygen. The purpose of starting at noon is to agitate the body of water and cause convection in the upper and lower layers of water. The surface and the upper layer of saturated oxygen are sent to the bottom layer. At the same time, the bottom or lower layer of hypoxia or anoxic water is sent to the upper layer, and the inorganic salt is brought to the upper layer. To provide nutrition for the upper phytoplankton and maintain the ecological balance of the water body.
When using oxygen aerators, the most important thing to pay attention to is to stick to the patrol pond to prevent blackouts. In this regard, great attention must be paid to it. In addition, we must overcome the fear of using more electricity. The use of electricity, especially for prolonged use of electricity, is heart-wrenching. However, due to the peculiarities of the shrimp farming industry, it must first ensure that there is sufficient dissolved oxygen in the pool to prevent accidents. A pond usually has about 10 acres. If the per mu yield is 400 kilograms, 30 yuan per kilogram, the output value will be 120,000 yuan. This 120,000 yuan may be lost overnight due to lack of oxygen. Experienced shrimp farmers speak well, preferring to use more electricity at the start, and they should not be deprived of oxygen for saving electricity. It can be said that ensuring that there is enough dissolved oxygen in the pool is the key to the success of shrimp aquaculture, which is particularly important for shrimp farming in winter sheds.
