Xiaotang Live Water Quickly Raise Grass Carp

The rapid culturing of grass carp by Xiaotang living water is a new technology for fish farming that has emerged in recent years. The 0.1-0.2 kilogram fish species are intensively reared for 5 to 6 months of Xiaotang Dahuoshui. Each end can reach 1.5-3 kg. In the second year, it can reach 6.5-8 kg and a small pond (30 m2). Can produce 200-300 kilograms of fresh fish.
First, choose the digging pond to seize the winter and before the spring plowing, choose a long-term clear water and irrigation and drainage management convenient, not washed by mountain floods, rely on the clay soil on both sides of the house, non-leakage plot excavation pond. According to the site conditions, dig small ponds 20-30 m2 in size and 70-80 cm deep. The pond side should be constructed without leakage, open the gutter (preferably a ditch), bury the water inlet and outlet pipes, and enter The water outlet is buried in a water pipe and it enters the house. Immediately after the digging of the pond, a fence was erected to protect against theft and poultry and livestock.
2. To raise fry before opening Xiaotang, it is necessary to breed 0.1-0.2 kilograms of robust, disease-free, non-injury, uniform-sized fry, with 400-500 tails per pond, which can be fed by villagers as a unit, or as a separate household. Or joint fish nursery to reduce costs and increase income.
Three kinds of good feed each 30 square meters of small pond raising grass carp, need to plant 400-800 square meters of forage grass, spring species of Sudan grass, goose, autumn ryegrass, but also to cut grass to meet the green grass carp feed need.
Fourth, small pond disinfection is generally 1.5-2 months before the release of fish species, every 30 square meters sprinkle 15 kg of mature lime, 60 kg of human urine, can be dried. The ponds were fished after three days of irrigation. This will increase fish disease resistance and survival.
V. Management 1. To ensure long-term irrigation of small ponds with large springs, pond water should achieve long-term string irrigation, which is the key to live fish in small ponds. If the water supply is insufficient, a small reservoir can be opened to catch the spring rainy season and reserve good water. In this rainy season or during drought season, it is also possible to ensure that fresh spring water can be used for irrigation and promote rapid fish growth. 2. Timely, quantitatively, and positioning feeds. The timing is 8-9am in the morning, and 2-3pm in the afternoon; quantitatively, 1.2-1.5 times of the total mantissa is to be placed; positioning, put the feed frame in the center of the pond, and feed should be feed in one hour after the feed is put on. Put it up and throw away the residue. In the hot summer season, it is in the cool morning and late afternoon. And put a pergola on the delivery box to avoid the hot sun drying materials to facilitate grass carp eating and increase appetite. 3. To train the fish to prevent fright, go to the edge of the pond every morning, evening, evening, and after 20-30 days, the fish will no longer be run away, and people will go down to the pond to catch and fish. Do not move, so even if the training is good, so that calm and rapid growth of fish security. 4. Fish disease prevention and control. In front of the fish ponds, 2% to 4% of salt water is used for dipping and disinfection. Except that the residual grass is removed after each feeding of forage grass for one hour, the bottom remnants and waste foods are thoroughly removed once every half month. Usually to put garlic, spicy material, wild gynostemma, and promote healthy and rapid growth of fish. 5. It is necessary to constantly inspect and reinforce the fence to prevent the theft and the livestock and livestock livestock from entering the pond. It is necessary to inspect and clean the fish after it is released, to protect the gutter, and to prevent mountain floods, pesticides, and sewage from entering the pond.
Sixth, pay attention to several points: 1. If the water temperature is lower after the fish species is under the pond, you should feed cooked sweet potato mixed with rice bran or wheat bran, or feed the fish pellet feed to ensure longevity. 2. Xiaotang must insist on pure grass carp in order to achieve high quality and high yield. For example, a miscellaneous fish pond should be set up for live fish breeding. 3. When grass carp grows to 1.5 kilograms, it can be selected to stay large every day. The density of sparse fish has a certain effect on high quality and high yield. 4. If the water supply is insufficient, the spring rain season can be seized. Assault stocking for 3-4 months, each fish can grow to 1-1.5 kg.
