First, pond conditions. The pond area is 0.67 hectares, with an average water depth of 1.2 meters. The pool pots are not leaky. There are plenty of water and dry grasses around the ponds. The non-grass ponds can transplant peanuts to account for about 30% of the whole area, which is beneficial to the treatment of astragalus. Inhabitation, non-polluting water sources, easy injection and drainage, and prevention of escaping at the water outlet.
Second, the clear pond and fertilization. Clear ponds are best prepared for quicklime. One lime per 667m2 is 1 meter and 150kg lime is used. The water is splashed all over the ground to kill all wild fish and bacteria in the pond. After the disappearance of the medicinal properties, 667 square meters of organic manure was applied to 1,000 kilograms. After 7 days, floating species of floating plants and animals can be used to release fish species. Third, seedling stocking
1. Fish stocking. In late February, fish ponds were farmed with fertilizers and fish, 400 were released every 667 square meters, 50% were white leeks, 20% were flowers, 15% were grasshoppers, and 15% were heterotrophic larvae (larger scale). , 0.2 kg per tail is good, for the seedlings to eat. The average size is 10 pigs per kilogram, and the purchase is sterilized with 3% saline for 10 minutes and then put into the pond.
2. Seedling stocking. In early May, the disease-free, lively and natural seedlings were selected. After purchase, they were soaked in 3% saline for 5 minutes. 3 tails/kilogram), the same pool must be equal to the same specification and 1 foot.
3. Bait fish stocking. Huangshao mainly eats oysters, clams, small fish, and shrimps. The author put 20 kilograms of ear fish and loach, because they breed quickly, the individual is smaller, the body is slender, fleshy, no hard thorns, often come out together with the jaundice at night and eat together inseparable, it is easy to be eaten by the astragalus, the loach grew up After the sale.
Fourth, daily management
1. Application, inorganic fertilizer. In February, there were no manure fertilizers of 1,000 kilograms per 667 square meters. After June, every 667 square meters was selected for a 5 kilograms of phosphorus fertilizer on a sunny day. The next morning, 75 kg of ammonium phosphate was applied. The water was splashed all over the place and fertilized once every 10 to 15 days.
2. Feeding. The ponds were cultured with whitefish, mainly fertilized, but they need to be fed with a portion of bait. The main ingredients include pancakes, corn, bran, fish bone powder, vitamin additives, etc., made into pellet feed, and the daily bait accounts for the total weight of bait fish. 3%~5% of them are fed twice daily.
3. Master water quality. As the main fertilizer fish, mainly to manure, floating plants and animals multiply, dissolved oxygen is low, such as the discovery of fish floating head lack of oxygen, to start aerobic equipment oxygen, summer and autumn will be discharged every week to add new old water Water 1 time to ensure that the water quality is fat, live, tender and cool.
4. Qintang tour. To do daytime nighttime tour ponds, find problems and solve them in time.
5. Prevent fish diseases. Disinfect the water once every 20 days from June, apply 20 kg of lime or 667 kg of bleaching powder per 667 square meters. The whole pool of water should be spilled. Sprinkle the fish and fish drugs must be staggered with fertilization, because the disinfectant can reduce the fertilizer effect. Regular preparation of baits for prevention and treatment.
Fifth, adult fish fishing. To carry out arrests in rounds to reduce the stocking densities, it will be 0.75 kilograms worth of adult fish caught on the market in late August, insisting on using big eyes to pull the nets, screen fishing, try not to dry the pond fishing, to prevent the yellow locust from freezing to death.
Six, yellow bream fishing. More than 150 grams of scutellariae per end, regardless of the season, prices as high as 35 yuan / kg or more. Therefore, I will use more than 150 grams of each end of the yellow cockroach fishing target. method 1.é³ é³ æ•æ‰ : : : : : : è´ä¹° è´ä¹° è´ä¹° è´ä¹° è´ä¹° è´ä¹° è´ä¹° è´ä¹° è´ä¹° è´ä¹° è´ä¹° è´ä¹°. At 18:00 in the evening, cages will be collected at 1 a.m., then the bait will be replaced, and then trapped again. Small-scale breeding will continue. 2. Unarmed capture: At 9:00 in the evening, when Aunt Huang is foraging on the shore, the entire body is exposed to the water and captured by hand. This method does not damage the seedlings.
