Liang Zhijian: make a lot of money by raising crayfish

In recent years, Liang Zhijian, a farmer from Banwei Village, Banfu Town, Zhongshan City, Guangdong Province, aimed at the market and explored a new way of breeding. For the first time, he introduced 100,000 crayfish from Wuhan for trial breeding and succeeded. He took the lead in exploring a way to become rich by raising crayfish in Zhongshan.

Liang Zhijian has been raising shrimp for 10 years. At present, he has 30 mu of shrimp pond. Raising shrimp for many years, he also encountered the embarrassment of high density cultivation in ponds and abnormal weather, which caused shrimp diseases to increase and benefit to decrease. If we get rid of the predicament and highlight the "encirclement", Liang Zhijian has repeatedly pondered the problem. In December last year, he invested 100,000 yuan to introduce 100,000 crayfish from Wuhan Yangtze River Basin Academy of Agriculture and Forestry Sciences into 8 mu pond for trial cultivation under the leadership of Huang Xiaowen, head of Guangdong Aquatic Products Special Research Center in Port Town. After nearly 3 months of breeding, the specification of crayfish grew from 100 per kilogram to 60 per kilogram, which has reached the market specification; However, Liang Zhijian is not eager to sell these crayfish as commercial shrimp, but to use them as female parent shrimp spawning shrimp seedlings. According to introduction, Liang Zhijian introduced crayfish each species shrimp can produce 200 to 400 eggs, shrimp egg hatching rate 80 to 95%, this year in April began to hatch shrimp seedlings, this can not only meet their own breeding seedlings needs, but also can be supplied to other farmers; at present the specification of 1 to 1.5 cm shrimp seedlings, every ten thousand seedlings sold to 350 to 400 yuan. "It is estimated that this batch of Japanese shrimp will produce 1000 seedlings by April, and you can earn a sum of money by selling seedlings alone." Liang Zhijian said excitedly.

Breeding and hatching crayfish, Zhongshan has not been tried by farmers, trial breeding effect is not known. In order to show his trial crayfish, Liang Zhijian walked into the winter shed and caught it with a "snake cage." He saw that the crayfish was only the size of a finger, dark red in color, and dancing with its big claws. Liang Zhijian fiddled with crayfish, while introducing to the author, crayfish adaptability is wide, can grow in various water bodies, water quality requirements are not high; both heat resistance, cold resistance, the optimum growth temperature 20 to 35℃, temperature below 5℃ is it will protect itself, drill into the bottom or mud natural hibernation. When the temperature rises to 10 ° C, crayfish become active and feed. Crayfish food miscellaneous, water lotus, water plants and other aquatic animals and plants can feed, coarse and coarse, no disease, usually sprinkle some lime disinfection can be. Compared with fish culture shrimp management is much simpler, raising crayfish does not need oxygenation, pesticide application, buy a lot of concentrated feed, save labor, save feed, cost is much lower, can save feed cost about 3000 yuan per mu. Liang Zhijian also said that two points should be paid attention to when breeding: one is to build winter shed insulation in winter to keep crayfish feeding, so that it grows faster, yields higher, and the Spring Festival listing price is higher; the other is to surround the edge of the pond with nylon film and plastic net or asbestos tile to prevent crayfish from escaping. When it comes to crayfish's "cultivation classics," Liang Zhijian is as precious as a few.

As for the economic benefits, Liang Zhijian said: "Crayfish breeding three months can be listed, a year can be raised three batches, yield 650 to 750 kg, sell to about 40 yuan per kilogram, deduct the cost of about 20 yuan per kilogram, per mu shrimp pond annual net profit of more than 40,000 yuan." He is also optimistic about the market sales of crayfish: "Crayfish taste delicious, rich in nutrition, low fat, high protein, large market demand, frozen processing export is in short supply trend, in addition in Wuhan, Shanghai, Xi'an, Hangzhou, Nanjing, Beijing, Chongqing and other places crayfish has jumped to the top of the consumption of' famous and special aquatic products', the market is very hot."

At present, Guangdong crayfish breeding has not yet formed climate, the development of artificial breeding, immediate results,"money" scene broad, farmers become rich short, flat, fast good project. Optimistic about market conditions and prospects, Liang Zhijian is now actively cooperating with the Port Town South Guangdong Aquatic Products Special Center to expand the breeding area to 150 mu, drink "first taste soup" and dig gold and silver.

Crayfish, the Chinese scientific name for crayfish, used to be a grass-roots aquatic product that few people asked for, but now its value is increasing. Crayfish farming has become a booming industry in China and is one of the successful examples of China's fishery industry restructuring.

Crayfish originated in the United States and then flowed into Japan. In the 1930s and during World War II, crayfish was introduced into China from Japan. It began to breed in Nanjing City and Jiaoxian County of Jiangsu Province. It is said that it wanted to clean up the river course by taking advantage of its mixed food habit, vitality and strong reproductive power. Later, it grew wild in the wilderness ditch. The shrimp belongs to warm tropical freshwater shrimp, which has fast growth speed, strong disease resistance, high temperature resistance, low oxygen resistance and will not die for several hours without water. It can live in freshwater lakes, rivers, ponds, ditches and rice fields. After a long time of expansion, it has wild reproduction in various water areas in southeast China. It is widely distributed in the middle and lower reaches of the Yangtze River, including Jiangsu, Zhejiang, Hubei, Hunan, Anhui, Shanghai, Shandong and other more than 10 provinces (cities) and regions. Gradually develop into a large number of wild populations, forming a certain scale of natural wild resources.
