Aquaculture to prevent rainy season
In June and July, it was a critical period for aquaculture production in the South. As the temperature and water temperature continued to increase, aquaculture animals entered a period of rapid growth. However, during this time, the weather is changeable. Rainstorms, thundershowers, and rainy weather are generally more common, which can have a greater impact on aquaculture. The majority of farmers need to strengthen fish pond management and disease prevention. The first is to strengthen water quality control. During this period, the food intake of fish increases, and the increase in excreta can easily lead to deterioration of water quality, resulting in lack of oxygen. Therefore, aerators need to be oxygenated in time every day depending on the weather, water quality, etc. In the event of showers or hot weather, the oxygen aeration time should be extended. It is necessary to constantly add new water, keep increasing the water level, and replace some of the bottom water properly. The second is to do a good job in disease prevention. Attention should be paid to the prevention of various types of fish diseases. Regular use of lime, chlorine dioxide, dibromohydantoin to disinfect or use microecological agents to improve water quality. The third is to strengthen daily management and stick to duty on duty. In seasons when the weather is changing, it is necessary to pay close attention to the observation of fish eating and behavior, especially in thunderstorms or hot weather. Oxygen deficiency warning signs (fish floating heads) should be promptly injected with new water and aerators should be opened to avoid pan fish dead fish. Heavy rains and showers have a great impact on the ecological environment of Penaeus vannamei culture, mainly resulting in instantaneous changes in the water quality (water temperature, salinity, etc.), plankton, and other aquaculture water environments of the shrimp ponds, resulting in a stress response to the shrimps and easily causing outbreaks of the shrimps. Disease. For example, due to the impact of typhoon and heavy rain in 2004, the aquaculture water environment has undergone abrupt changes, which has led to a serious disease of P. vannamei in our city. The lesson is particularly profound. Therefore, Penaeus vannamei farmers should pay particular attention to management during the heavy rain. The first is to maintain a certain water level so as not to affect the salinity in the pool during heavy rain. The second is to open the aerator to minimize the changes in water temperature and salinity in the pool. The third is to disinfect in time, and appropriate oxygenation agents and microbial agents can be applied before sterilization. Fourth, in the feed can be properly added VC, immune enhancers, probiotics, etc. to enhance the prawn physique. Fifth, strengthen the patrol pool and observation, and do a good job of prevention.
