It is better to breed by single cranes. That is, a small hole is drilled with a drill in the coronal crown, and each cormorant is put on a bamboo frame or bamboo frame by suspending a nylon rope or a plastic rope. The line spacing is about 1m, the spacing is about 3cm, and the acreage is 1000 per acre. Only about. The environment of the sloping waters requires sunny ventilation, there are no tall buildings and shaded trees, water depth is more than 1m, there are no aquatic plants, there is faint water flow, and the water quality is neutral. To prevent poisonous sewage from entering the cultured pearl field.
There is no predatory organ, and only the water flow formed by the activity of the cilia is used to ingest food. Therefore, the fish should be kept in the most abundant water layer. When the water temperature is 10-30°C in the spring and autumn, the oysters are suspended from the water surface 20--30cm. At the height of mid-summer and winter, it is better to hang about 70 centimeters from the surface of the water. In winter, aquaculture waters do not need to be fertilized. In spring and autumn, inorganic and organic fertilizers should be applied to fertilize the water quality, promote the growth of plankton, and provide rich food for earthworms. In summer, the temperature should be high and inorganic fertilizers should be applied.
