We should always observe the weather, understand the weather changes and master the future weather forecast, so as to do a good job in prevention. Before the arrival of typhoon weather, it is necessary to conduct a comprehensive inspection of large-scale infrastructure construction such as warehouses, river embankments and their mechanical equipment, and power engineering. If there is any damage, it should be repaired in time. Subsequently, the aquaculture ponds with too dense and heavy silt should be improved in time to prevent the bottom of oysters from flooding. Then, we should do a good job in the preparation of concentrated solution, drugs and other materials in order to properly handle the corresponding problems and reduce losses.

2. Strengthen management

Typhoon weather not only produces storms, but also the ambient temperature drops sharply when precipitation increases, which is very unfavorable to the production and manufacture of aquatic products. Moreover, when it rains, the water body is easy to be layered, such as halocline unit and oxycline unit. Therefore, the oxygen pump should be turned on immediately, and oxygen should be injected into the pond to prevent the phenomenon of moisture layer, and the drainage pipeline should be disinfected and sterilized. In the case of heavy precipitation, we should pay attention to ensuring the novelty of materials and patrol frequently. Strengthen epidemic monitoring and detect water quality. , if there is any abnormality, take corresponding countermeasures in time.

Second, after typhoon management 1, properly handle it.

For dead fish and shrimp, it is necessary to catch them in time and treat them harmlessly to prevent water bodies from being polluted by the environment due to the decay of corpses, and make records to facilitate replanting in the future. In addition, it also solves the problems of identifying escaped river shrimp, mastering the existing quantity, and clarifying the types and usage that should be supplemented. In view of the damaged animal husbandry and breeding equipment, it is necessary to repair it in time, reinforce the river embankment structurally, discharge unnecessary water and resume normal production and manufacturing as soon as possible. Subsequently, the equipment that has reached the saleable specifications and models should be salvaged and sold in time to prevent the loss from expanding.

2. Maintenance management

After the outfield water level line is lowered to the safe boundary, the water level should be removed and replaced in time, and the water level line should be kept within the normal range. The water in the fish tank should be changed from shallow to deep, and the flow rate of water change should be kept at 1/3. Adjust the PH value of water surface, promote microbial fertilizer to improve water quality and maintain pond fertility. If the water quality is too strong, microecological agents should be used reasonably, and the oxygen pump should be turned on to prevent the water from lack of oxygen. Then disinfect the pond, and if there are pests and diseases, use standard antibacterial drugs in time. If there is no commodity, then it is necessary to clean the pond and carry out exposure disinfection and sterilization. Finally, based on accurate positioning and timely qualitative and quantitative analysis, high-quality fresh concentrate feed and vitamin supplement should be popularized.
