First, the appropriate "early" character: Early release fish species, fish activity is small, not easily infected. Early adaptation to environmental conditions, the best stocking in early March. The main raising fish and grass carp ponds, 300 acres of carp stockings, 300 grass carp, 100 white locusts, 20 pods, and about 700 rearing stocks/mu. Early stocking, early feeding, early growth, early management, early out of the pond, (out of ponds in July, and then reared fish species). Second, choose the "big" character: Large fish species size, physical fitness, water temperature the same intensity of food intake, rapid growth, require squid, squid, squid species are more than 250 grams per tail, more than 350 grams of grass carp, the main The ratio of carp and grass carp is approximately 1:1. There is a large amount of principal investment for fish species, and the price is high for outlet ponds. The price difference of fish species itself is large and the economic benefits are large. Third, the reasonable "cast" word: The main carp carp, grass carp ponds, in the early vote foot grass, there are plans to feed the bait, generally taken in March for 1%, 7% in April, 9% in May, 63% in June Depending on the temperature of the water, the number of feedings is taken once to six times a day, and the rate of feeding is eight to ninety percent full. When the feeding is too large, the fish species will jump out of the water, and the adult fish will sink into the water after being probed on the surface of the water. When the feeding is over, the digestive absorption rate of the fish is reduced, and the disease is susceptible to enteritis. Fourth, to highlight the word "defense": Fish live in water, once the disease is difficult to treat, reflecting the importance of "prevention". The main squid and grass carp began to prevent parasitosis in late April. 90% of crystal trichlorfon 0.3ppm-0.5ppm Quanchiposa was used, and it was applied again in late May. From May to June, internal consumption and external consumption methods were taken orally: the main grass carp was fed with 100 mg of compound sulfamethoxazole and 100 tablets of 2.5 g-50 g of rhubarb mixture per 100 kg bait, once every 10 days for 2 days. -3 days. The main cultured squid is mixed with oxytetracycline, and 100 kg of bait is mixed with 50 to 100 grams of oxytetracycline to prevent 20 days to 30 days. The benefits of oxytetracycline in preventing fish diseases: In the appropriate amount, the growth rate of carp is accelerated by 5%-25% and the feed is saved by 10.5%. For external use: In early May, throw 0.3ppm-ppm0.5 Quanchiposa once and later use 20ppm-25ppm quicklime to spray once, and apply it again in June. Fifth, the use of "exchange" word: Stocking water depth should be more than 1.2 meters, to prevent bad weather on fish hazards. The water injection began in late April and the water injection was increased in mid-May. The maximum water level reached 2 meters to 2.5 meters in mid-May. The start of water injection in mid-June should be carried out simultaneously. Each row of water should be between 10 cm and 15 cm, so that the fish will have good living conditions. Six, flexible "smart" word: clever, clever, clever use is the key. Coincidentally: 1 weather: even rainy days, hot weather, low pressure, low feed, sunny weather, high water temperature can be fed more properly. 2 Water: Within one day, the water in the pool is different in early, middle, and late colors. It is light and dark in the morning and there are no floating membranes in the grass green, yellow-green, and water. The water color changes from green to red or black as bad water. 3 Ingestion: The fish have a strong ability to compete for food, have a large food intake, light body color, and shiny luster is a good food. The first meal of the fish was not very busy. It was eaten back and forth. The second meal increased sharply, indicating that the water was deprived of oxygen. Failure to ingest food within one day indicates deterioration or morbidity of water quality. Cleverly listening: Night patrol ponds, with flashlights shining on the surface, a corner of the pool or a "bang" sound, the response quickly became a frivolous head. Quanchi appeared to be a general floating head. Flashlight can see that the floating head of the fish is a serious floating head, and the fish body pigment gradually fades, and the salvage does not die in time. Clever use: The rational use of aerators can save electricity and reduce costs. It can release harmful gases to purify water, reduce and prevent various bacterial diseases, and provide oxygen for fish. Improper use can cause adverse reactions: 1 Hydrogen sulfide poisoning, the use of oxygen can accelerate the decomposition of hydrogen sulfide, should be taken while the side of the water, while using peroxides and other oxygenation agent oxygen, the use of iron salts and other poisoning prevention and control. 2 The lack of oxygen in the pool, no pool fish used aerators, the fish were frightened, scurrying around, causing various illnesses or death.
