The Spring Festival is approaching, which is an important period for the capture of aquatic products. Growing fish is mixed with the fish that is about to be raised, so you should pay attention to the anti-freezing of fish species. Do not operate when there is freezing. Water should be added to ensure a depth of 1.5 to 2 meters to stabilize the temperature. Try to avoid exposing the fish to the air. Fish to be caught should be bathed in 2% salt water for 15 to 20 minutes to prevent water mildew. Where the eel is raised in the cage, the cage should be sunk to the bottom in time, come into contact with silt, and the box should be covered with straw to minimize operation and ensure safe overwintering.

All kinds of viruses in livestock and poultry like cold and heat, and it is necessary to earnestly do a good job in the prevention and control of highly venereal diseases such as avian influenza, blue ear disease, and foot-and-mouth disease.
