The technique of how to cultivate Loach

Misgurnus anguillicaudatus is a kind of small special fish with wide distribution and large quantity, which has delicate meat, rich nutrition and delicious taste, so it is very popular in domestic and foreign markets. It not only has high edible value, but also is a kind of nutritional supplement with high medicinal value. Misgurnus anguillicaudatus meat is light and delicate, delicious and nutritious. According to the analysis of authoritative departments, the meat of Loach contains a variety of nutrients necessary for the human body, such as protein, fat, sugars, vitamin B2, vitamin B5 and 12 trace elements such as calcium, phosphorus and iron. In particular, the protein content is as high as 22.6 grams per 100 grams of Loach meat. Misgurnus anguillicaudatus grows in most parts of the country, has strong ability to adapt to the environment, and the culture technology is easy to master. Loach can be cultured in rice fields, ponds, lakes and ditches, and farmers can choose the appropriate culture mode according to their own conditions. The investment in the cultivation of Loach can be small or large, the investment of several hundred yuan or thousands of yuan can be small-scale trial culture, and it can also invest millions of yuan or tens of millions of yuan in large-scale breeding, and can completely solve the problems of seedling and feed. Among the large-scale farming methods in the country, rice field culture and pond purse seine intensive culture are more common and efficient. Case study: this is a relatively simple way of breeding, and it has formed a large scale in many places. Dong Bing, a farmer in Macheng Town, Huaiyuan County, Anhui Province, contracted 2000 mu of low-lying land in 2004 and raised Loach in more than 100 mu of rice fields with a trial attitude. He harvested 50 kg of Loach per mu that year, with a total income of 80, 000 yuan. After tasting the sweetness, he continues to expand the scale of breeding. In 2005, the breeding area has reached 1100 mu, and the income of Loach per mu of rice field has reached more than 1000 yuan. Lao Dong said that the feces of Loach can be fertilized in the field, and Loach likes to eat pests in rice fields. Raising Loach in rice fields can reduce the amount of fertilizer and pesticide use in rice fields by 2%. His rice yield per mu has increased from 450kg in the past to 650kg now. Growing rice and raising Loach in paddy fields can increase the income by nearly 2000 yuan per mu. With the continuous improvement of the technology of cultivating Loach in rice field, the yield of Loach can reach 150 kg per mu in Huaiyuan County. Brief description: Rice Loach concurrently type, that is, rice Loach co-culture type, is to grow rice while raising Loach, rice Misgurnus anguillicaudatus, strive for a bumper harvest. After ploughing and drying the paddy field, the bottom of the fish is covered with organic fertilizer as the base fertilizer, which is mainly used to cultivate biological bait for Loach to feed, and then the whole field. Misgurnus anguillicaudatus seedlings are generally released after transplanting rice seedlings, single-cropping rice fields are best released after the first weeding, and double-cropping rice fields are best stocked after the second rice seedlings are planted. Misgurnus anguillicaudatus culture model pond purse seine fine culture model case: most of this culture method is to simply rebuild the rice field, and then carry out the purse seine around to carry out Loach culture. This culture method began around 2003. At present, this culture method is used to cultivate Loach with high density all over the country. In Dunshang Town, Ganyu County, Jiangsu Province, pond purse seine culture of Loach was developed in 2007, and an average profit of 20, 000 yuan per mu was obtained. Brief description: the water retention performance of the pond is good, and the cement pond or soil pond is suitable. The area of cement pool should be 150 square meters ~ 300 square meters. The area of the earth pond is 667 square meters ~ 2000 square meters, and the bottom of the pond should be clay. The depth of the pond is 80 cm ~ 120 cm, the silt at the bottom of the pond is 10 cm ~ 20 cm, and the water depth is maintained at 50 cm ~ 80 cm. The bottom of the pool is inclined to the outlet, forming a certain slope. 1. The water quality is sufficient, the water quality is fresh, and the drainage and irrigation are convenient. The water quality of the source shall comply with the regulations of GB11607. The quality of aquaculture water should meet the requirements of NY5051. Aquaculture drainage should comply with the provisions of GB18596. two。 The ecological environment of the breeding site is good, in the breeding area and upwind, upstream of irrigation water sources, there are no pollution sources that pose a threat to the environment of the producing area (including industrial "three wastes", agricultural wastes, sewage and wastes from medical institutions, municipal garbage and domestic sewage, etc.).
