Bailu is China's lunar solar term, and it is - during the middle and mid-autumn seasons, the water temperature varies widely between day and night, and various physical factors in the water will change. Fish cannot be adapted to the drastic changes in the water environment because of physiological factors. "White Dewberry" refers to the collective name of fish disease occurring before and after dew exposure. It can usually be divided into three types: First, bacterial fish disease. Such as gill disease, red skin disease, enteritis disease, bacterial bleeding, etc.; second is parasitic disease. Such as small echinococcosis, trichoderma, sporeworm disease, anchor head lice, fish gills, etc.; third is the pan-tang syndrome. Mainly fishpond hypoxia, ammonia nitrogen poisoning and other syndromes. Due to the viciousness of the "White Dewberry", there are many types of diseases, which often result in serious losses of farmed fish. It is very important to do a good job of preventing white dew. It can take the following three specific measures. I. Improve water quality 1. Change water in time, try to control the water level, keep the water quality fat, live, tender and cool. 2, regular application of lime, adjust the water pH. Lime consumption is 10-15 kg per acre, splashed with water. Second, strengthen feeding and management 1. The feed should be fresh, not bad, bad, full nutrition, good palatability, to meet the nutritional needs of fish. 2. Adhere to the principle of "Four Ding" feeding and keep a flexible grasp of weather, water quality, and fish activity. Third, fish disease prevention 1, Quanchiposa drugs. With 90% crystal trichlorfon, 0.3-0.7 grams per cubic meter of water, can kill the head of the head, Chinese sturgeon, third generation of insects, etc.; control of small melon worms can use chili powder and ginger, - the amount of water per cubic meter 0.8-1.2g and 1.5-2.2g, add water and boil for 30 minutes and even spill the residue with the juice Quanchiposa, once a day, once every 3-4 days; to prevent the trichoderma can choose to use buckwheat leaves, - the amount of water per cubic meter 40-50 grams, decoction juice, the disease epidemic Quanchiposa, 15 times a day. Bacterial fish diseases can be prevented by disinfectants such as bromochloroheine, dibromohydantoin and chlorine dioxide. 2, feeding baits. Such as the prevention of bacterial enteritis, can choose to use garlic (when erosion) or allicin or salt, - the amount of feed per 1 kg of feed 5 grams or 0.02 grams or 0.5 grams of mixed feed, 1 day 2 times, once every 3 days: Candidates such as Andrographis paniculata, Daqingye, Scutellaria baicalensis, Morus alba, and Radix Paeoniae Alba are also available. Once in each dose, 40g, 30g, 5g, 10g and 5g per 1 kg of feed are mixed into a powder and mixed feed. 3. Use biological agents to improve water quality and prevent fish diseases. At present, the biological agents used in freshwater aquaculture include Bacillus subtilis, EM bacteria, photosynthetic bacteria, yeasts, lactic acid bacteria, etc. They can kill or engulf pathogens in water bodies, purify water quality, maintain good water quality, and have appropriate transparency. Reduce disease damage to fish. Practice has proved that the use of probiotics can not only regulate water quality, but also increase fish production and raise the breeding efficiency. Anoxic flood ponds, the main measures can be changed water, flushing or use of mechanical oxygen, emergency oxygen can be used to solve the oxygenating agent. Ammonia poisoning is mostly caused by overfeeding, resulting in ammoniation of protein in feed. Feeding should be scientific and reasonable to prevent deterioration and deterioration of feed and affect water quality. If ammonia poisoning occurs, new water should be added in time to dilute the concentration of ammonia nitrogen in the original pond to prevent poisoning. You can also use probiotics and long-acting oxygen, once the amount of 250-333 grams per acre surface, Quanchiposa 1, 15 times in the middle and late breeding.
