There is a "shrimp king" Zhou Shiliang in the greenhouse.

Nowadays, it is the time for the South American white shrimp to be put on the market, and the South American white shrimp raised by Zhou Shiliang at the Chaoyang gate in Yinong town sold out as early as a month ago, and the banknotes have been put into the pocket. The second batch of South American white shrimp will also be launched later this month, and fishing is expected to begin by the end of October. This year, Zhou Shiliang farmed Penaeus vannamei made a net profit of more than 5000 yuan per mu in the first season, which is 2-3 times that of ordinary farmers, making him a well-known king of shrimp farming.

These days, Zhou Shiliang's mobile phone has become a hotline, some come to ask for advice on shrimp farming experience, some to confirm the news, some to congratulate …... The dark-skinned farmer really tasted the sweetness of the "bumper harvest". Zhou Shiliang, who started with 3000 yuan and started a professional farming company of more than 40 years, is now the boss of Changda Culture Co., Ltd., one of the largest white shrimp farming companies in our region. The existing aquaculture area of the company is nearly 3000 mu, and the culture area of Penaeus chinensis accounts for 90%. Perhaps no one would have thought that this large-scale company with fixed assets of more than 30 million yuan and more than 300 employees started with a capital of 3000 yuan. More than 10 years ago, Zhou Shiliang, a native of Hezhuang, gave up his job at Hongkun Farm and came to Yinong Town to contract 3000 mu of land to grow vegetables, watermelons and other cash crops with the money he had accumulated over the past few years. Zhou Shiliang recalled: "at that time, it was really hard. I didn't have any mechanical equipment. I relied on my own hands and dug with my hands. Especially in winter, when I went to work in the fields, I felt like stepping barefoot into a glacier." A few years later, Zhou Shiliang was acutely aware of the great achievements of aquaculture. So he decided to experiment with a 5-acre pond to raise lake crabs. Sure enough, at the end of that year, the highest price of his lake crab was 360 yuan / kg, and the small 5-mu crab pond made a profit of 60,000 yuan. The success for the first time aroused Zhou Shiliang's enthusiasm for investing in aquaculture. After that, he attended various training courses and asked aquatic experts for advice on aquaculture and aquaculture techniques. In the following year, after conducting extensive market research, Zhou Shiliang set up a professional farming company and began to raise Penaeus vannamei. Greenhouse culture, breaking the tradition of "relying on heaven for a living", Penaeus vannamei is a kind of high temperature resistant shrimp, which has great risk in culture. The annual plum rain season and typhoon season are all ridges. In the event of typhoons and torrential rains, the sudden drop in water temperature in shrimp ponds will lead to the death of a large number of shrimp. How to change the status quo of relying on heaven for a living? Zhou Shiliang, who had no previous experience of raising shrimp, flipped through a lot of books, but never found any way. "finally, a few years ago, I was inspired by the fact that vegetable farmers in Sanwei Village made high profits by growing vegetables in the greenhouse." Zhou Shiliang smiled and said, at that time, he thought, can we also learn from the way of growing vegetables in greenhouse to raise shrimp and take the road of greenhouse culture? As soon as he thought of it, Zhou Shiliang built white sheds for shrimp ponds and began his "innovative breeding method." Breeding in greenhouse starts with raising seedlings. After doing the routine cleaning and disinfection work, Zhou Shiliang built a steel-bamboo mixed greenhouse and laid oxygen-increasing pipes and other ancillary facilities at the bottom of the pond. At the end of March every year, Zhou Shiliang temporarily raised millions of shrimp fry in the greenhouse; more than 40 days later, he put the young shrimp into an open-air pond to let them adapt to the "outside world." "raising seedlings in the greenhouse one month in advance can avoid two high-risk periods. One is the rainy season. Because the shrimp has grown up at this time, it is not easy to get sick; the second is the influence of typhoon. July and August is a typhoon-prone period. If seedlings are raised one month in advance, they can be caught in June, so they will not be affected by the typhoon. Zhou Shiliang says that avoiding these two high-risk periods is like insuring shrimp and ensuring shrimp farming. "of course, choosing a good variety is also the key." Zhou Shiliang said that the varieties chosen by ordinary farmers are relatively random, while the varieties he chooses are generally of "high grade". Although the price of the variety is about half higher than that of ordinary varieties, it has a high survival rate and strong anti-risk ability, and is absolutely "value for money." In order to speed up the industrialization of Penaeus vannamei, Zhou Shiliang also invested more than 6 million yuan to purchase a set of quick-frozen deep processing equipment for aquatic products and created his own "Changda Brand" series of aquatic products. Today, Zhou Shiliang's South White shrimp products from breeding to production, and then to deep processing, are all one-stop "services." his products are exported to South Korea, Japan and other places, and have a large number of repeat customers.
