"Crab Brother" sets up a "raw gold shed" for crab farmers to get rich.

In the crab breeding base of Bingling Aquatic products Co., Ltd., a circular economy industrial park, Lu Weibing, known as "Brother Crab" by crab farmers across the country, invested 3 million yuan to build a 200mu steel frame bean crab breeding greenhouse here. Today, the reporter came to the nursery base and saw only 200 mu of steel sheds lined up, and more than 20 workers were cleaning ponds, arranging supply and drainage pipes, and doing preparatory work for the cultivation of bean crabs.

Lu Guardian, who is tidying up the water pipes with the workers, laid down his work and told the reporter that in the past two years, with the development of the national river crab industry, crab farmers have higher and higher requirements for crab species. According to his observation, in addition to requiring parent crabs to be authentic Chinese mitten crabs in the Yangtze River system, customers require 160 crabs per kilogram. Last year, he conducted a small-scale breeding of 20 mu of bean crabs in a greenhouse on the breeding base, and sold 2000 jin of bean crabs to more than 100 crab farmers in Anhui, Taihu, Baoying, Tangshan and other places. The practice shows that the crabs in the same batch of buckle crabs grow fast in the second year, reaching about 250g per crab. Gu Jiemin, a big farmer in Wuwei County, Anhui Province, bought his 200jin bean crabs and put them in a 400mu pond. The income of deducting crabs per mu reached 13000 yuan that year, which caused a sensation in the local area.

"now that the greenhouse has been built, in the past two days, we should drain the water of the pond and plough the bottom of the pond for a few more days, and then wrap it around the pond with net gauze to prevent bean crabs from burrowing. After re-entering the water, bleach disinfects, kills all pests and pond buckle crabs, and lays flat tiles on the bottom of the pond for bean crabs to live in caves and prevent mutual mutilation and escape. At the same time, cultivate biological bait, use mature livestock fertilizer 50 kg per mu, so that the pool water is slightly green, there are microbes swimming in the water, providing high-quality bait and growth environment for bigeye larvae. " When it comes to the process of preparing for cultivation, Lu Weibing goes on and on. He said that aquatic plants will be cultivated in a few days, and about 15 days before seedling application, aquatic plants such as water peanuts will be put into the pond to allow them to grow rapidly. Aquatic plants cover about 1/3 of the water area, providing a place for bean crabs to perch and shed their shells. At present, the kinds of crabs used have been selected and purchased, and the 200mu greenhouse can produce about 20,000 jin of bean crab seedlings, which can meet the needs of more than 1000 crab farmers in China. If the specification of buckle crabs reaches 160kg next year, he will buy them all back and raise hairy crabs in high-quality lakes in China.
