First, the position of the aerobic engine should be as far away from the Tangkou as possible. The growth of oyster shells of juvenile crabs requires a relatively quiet and comfortable environment. Although the influence of noise from pipeline aerators is relatively small, they should still be as far away as possible from the mouth of the pond in order to provide a more suitable growth environment for the clams of juvenile crabs.
Second, rubber and plastic integrated microporous pipe should be kept at the same level as possible, which is conducive to the supply of oxygen at each oxygen supply point, if it can not be done, should be based on different shades of crab pool, properly increase the power of aerator.
Third, the pipe micropore aerator has a large load area, which is 2 to 4 times that of the impeller type aerator, and the electricity consumption is relatively small. The farmers should start more and avoid idleness.
IV. When the pipeline micropore aerator is used, if the noise emitted is relatively large, the outlet pipe is hot and hot, indicating that the number of micro-holes in the pipeline is not enough. The number of micro-holes should be increased or the length of the pipeline should be increased in order to increase the total gas output.
V. Once the microporous aerator for pipelines is installed, it should always be turned on to prevent the pores from plugging. Every year after the end of winter fishing, it should be cleaned.
6. The shallow waters of Crab Pond are rich in dissolved oxygen. Young crabs prefer to stay in deep water during high temperature. Therefore, the aeration pipes are mainly arranged in deep waters to better suit the high temperature period. Young crabs inhabit in dissolved oxygen while the water temperature is relatively high. Low demand.
