First, prevent hunger and adult fish in the growing season, eating large amounts, should be more feeding and feeding. For fish ponds such as grasses, clams, and tilapia, feeds such as bran, cake pancakes, and bean dregs, as well as fresh feeds such as young grasses, plant stems, and leaves are to be cast. Under normal circumstances, Japan's crude material accounted for 10% of the total fish. Second, anti-nutrient fertilization season of the fish need to fertilize the fertilizer should account for 80% of the entire period, so every 5 days to 7 days, Mushi full fermentation of human and animal manure 60 kg to 100 kg, nitrogen, phosphate 2 kg ~3 kg. Third, the temperature of the fish is too high. The suitable growth temperature for the fish is 23°C~39°C. In the hot season, the water temperature is too high. It must be filled with fresh water in a timely manner. The fishing pond of about 1m in the water layer is filled with 1/10 new water every day. water. Fourth, prevention of hypoxia summer, fish oxygen consumption, coupled with the decomposition of a large number of fertilizers and organic matter, can easily lead to hypoxia. Therefore, oxygen-increasing equipment should be installed. Where there is no oxygen-increasing equipment, 10% of the pond water should be filled with fresh water, supplemented by artificial oxygen. V. Anti-floating heads Due to the hot weather, the water pressure is reduced and the fish clusters breathe on the water. This is the "floating head." According to the cause and severity of floating heads, targeted measures should be taken. For example, floating heads caused by large amount of feed should be oxygenated in a timely manner and be filled with fresh water. 6 kg of lime or 2 kg of alum or 2 kg of salt should be used. , Dissolved after spilling; fishing net water debris, residual grass, floating foam and so on. 6. Prevention of "anti-water" reversal of water is also called water disease, which often occurs in sandy bottom clear water ponds where rain is too long. It was originally a pool of water that often became "clear and clear" overnight. The main reason is that there are many large-scale zooplankton species such as cockroaches, cladocerans, and copepods in fish ponds, and large amounts of phytoplankton are ingested. In addition, the increase of new water volume in rainy ponds has destroyed the ecological balance in the pool. The effective methods of prevention are: increasing the number of carp and tilapia, controlling the number of zooplankton, spraying 9% of crystal trichlorfon solution, and combining artificial fertilization, the pool water will soon become fat. VII. Waterproofing aging As the temperature is high, fish grow fast, and the quality of pond water will change from slightly alkaline to acidic and aging, which will seriously affect the reproduction of natural baits, reduce photosynthesis and inhibit the growth of fish. Every half a month, 20 kg of quick lime should be used, and the whole pool should be sprayed evenly after dissolution. VIII. Disease prevention Fish growth season is also a frequent occurrence of fish diseases, especially enteritis, gill rot and water mold. Every month, bleaching powder Quanchipite spilled one time, so that the pond water showed a concentration of 110-6; in the green feed mixed with bleaching powder; the leeks, garlic mash, the amount of added green feed. 10kg to 15kg of lime per acre is poured on the water. 9. Anti-Algae Poisoning As the water temperature rises, algae multiply, and when they reach a certain level, they are easily eaten by fish and cause death. Therefore, copper sulfate must be used to kill algae in time. Tenth, prevent the escape of summer storms and more, the fresh water will make the fish become very active, when the pool water level rises or full, it is necessary to timely raise the net rope, strengthen management, find problems and timely rescue.
