Culture techniques for breeding Loach

Misgurnus anguillicaudatus is known as "ginseng in the water". It is delicious, tender and nutritious. It also has high value in medicine, and it is one of the important aquatic products exported by our country. Misgurnus anguillicaudatus has become an important aquaculture species because of its strong adaptability, few diseases, high survival rate, strong fecundity, convenient transportation and easy availability of bait. Pond construction: choose a place with shelter from the wind to the sun, convenient water diversion, weak alkaline substrate and no pesticide pollution to build a pond. The pond can be a cement pond or a soil pond. The wall of the earth pool needs to be built with bricks and stones, or hammered with concrete, and the bottom of the pool needs to be rammed so that it is sturdy and durable without loopholes, and the bottom is covered with 20-30 cm of fat mud. The inlet and outlet is blocked with a wire or plastic net, and the bottom of the pool is tilted toward the outlet for drainage and fishing. Water cultivation and sowing: the pond is cleaned and disinfected according to the seedling cultivation method, the water depth is kept at 30-50 cm, and organic fertilizers such as pig manure are applied to cultivate water quality, with a dosage of 100 square meters and 20-30 kg. After the medicine disappears and the pond water turns into fertilizer, the species of Loach can be put in, and those with running water can be increased appropriately. Feeding management: on the basis of improving water quality and providing natural bait, it is necessary to increase the feeding of animal feed such as maggots, earthworms, clam meat, fish meal, small miscellaneous fish meat, livestock and poultry scraps, as well as plant feed such as wheat bran, rice bran, bean dregs, cakes, or artificial compound feed. It is generally fed once a day in the morning and afternoon, and the daily feeding amount is 5% of the body weight of Loach. 10%. Feeding should be flexibly controlled according to water quality, weather and food intake. The appetite of Misgurnus anguillicaudatus gradually increases when the water temperature is above 15 ℃. The range of 20-30 ℃ is the optimum temperature for feeding. The appetite of 25-27 ℃ is especially strong. It can not be fed in thunderstorm days when the temperature is more than 30 ℃ or below 15 ℃. In addition, reasonable fertilization should be carried out according to the water quality and fertility, the transparency of the pool water should be controlled at 15-20 cm, and the water color should be yellowish green. When the water temperature reaches 30 ℃, the pool water should be changed frequently and the water depth should be increased; when the Loach often swims to the surface to "swallow air", it indicates that there is a lack of oxygen in the water, so fertilizer should be stopped and new water should be injected. The depth of the pond water should be increased in winter, and barnyard manure such as cow manure and pig manure can be applied in the pond corner to improve the water temperature and ensure the Loach to survive the winter safely. I hope you can give me more suggestions-thank you for sharing! When I was a child, there were a lot of Loach in the field outside my house. I spent all day in the field in summer. Later, there were more pesticides and batteries. Now there is only mud and water left in the canal. The Loach is very delicious, especially when we have bacon. A piece of roasted meat is more delicious. I think the market for Loach should be quite big. In the past, it was 5 yuan per jin in our house, but now it is 12 or 3 yuan. Quite a shooter.
