Trở thành triêu phú từ mô hình Nuôi tôm trong nhà kính

For more than 10 years, Mr. Tran Van Minh, a shrimp farmer in Loc Ha, has understood the economic benefits of this profession. However, in recent years, the weather has been unfavorable, so shrimp farming has become a gamble with the sky. Faced with the risks caused by the weather and the unusual climate, many shrimp farmers have had to quit their jobs. Not surprisingly, Mr. Minh has dedicated himself to researching and studying the technology of shrimp farming in his greenhouse through the Internet and has received timely assistance from the Department of Science and Technology. In March 2019, he decided to invest in a greenhouse system for shrimp farming. In the old shrimp farm area, the family raised funds to build three greenhouses, with an investment budget of more than 300 million VND per house. Currently, one house has been used in the recent flood. Although it is a shrimp farm, the 10 million shrimp raised in the greenhouse have developed quite well. At present, it is expected to weigh 50 shrimp per kilogram. According to the plan, by the end of March, the shrimp will weigh 30 shrimp per kilogram and will be harvested. Thus, the profit of harvesting can reach 250 million VND after 3 months of raising. Thanks to the greenhouse, Mr. Minh can raise up to 4 shrimp per year, which means that the profit can reach 800 million VND after 12 months. In the past, I raised shrimp outside the greenhouse. Due to the weather, when it was sunny and rainy, I couldn't do it. So I decided to move to the greenhouse. In the greenhouse, I could only raise a handful of shrimp, so the development was very good. In general, when it rains, it is sunny, when it rains, it is sunny. When it rains, the price of food is higher, the cost of living is lower. In general, there are many areas where it is more effective to raise shrimp than outside. I only meet 2-3 times outside. The greenhouse system will create a special environment for raising outside, which makes it easier to manage the temperature. Specifically, in the cold season, the average temperature in the house can increase by 8 degrees, and in the summer it can decrease from 8 to 10 degrees. Due to the lack of environmental impact, it is easy for farmers to control the disease. Since then, the rate of life and shrimp density in the greenhouse has increased by 1.5 to 2 times compared to the traditional way of raising shrimp. In the shrimp-raising areas, Anh Minh designed 8 ponds for each house. Each pond is 25 meters of water, which is easy to manage and reduce costs, as well as provide oxygen for shrimp through the ventilation system from the bottom. The height of the house is only 3 meters, which helps to limit damage in the rainy season. During the process of raising shrimp in the greenhouse, farmers outside may not be affected by the environment. For example, in the cold season, the temperature will increase by 7 degrees, and in the summer, the temperature will decrease by 7 degrees. In general, with these conditions, the cost of development is very good. The height of the house is only 3 meters, but the climate in the greenhouse is very bad, and the wind blows a lot, so the shrimp will be less affected. The design of the shrimp-raising area is 25 meters of water, which is easy to manage and reduce costs. For example, in some areas, they raise shrimp from the bottom of the pond, but they have to use a fan, which increases the cost of electricity. In small ponds, there is only oxygen, no need to use a fan. In 2019, with the support of the Ministry of Technology, the center cooperated with the local government and the model makers to research and apply the technological advancement of shrimp-raising in the greenhouse. Through the process of developing this model in 2019, the evaluation of the effectiveness of the model of raising shrimp in the greenhouse and in the cement-covered area in the old-fashioned way, the effectiveness of this model has increased compared to the old-fashioned production method, so the three shrimp-raising farms in Ban Huyen are highly rewarded. The construction of a greenhouse to raise shrimp has avoided the effects of the weather, maintaining a suitable temperature for each season. Since then, people can raise shrimp all year round without fear of hot or cold weather, which affects the growth and development of shrimp. Clearly, in adverse weather conditions such as in Ha Tinh, this is a model that shows excellent results. The science and technology industry has soon met this requirement to jointly accompany the farmers of the aquaculture, as well as the farmers of agricultural production in general. In the field of agriculture, new technologies such as the application of new technologies have been applied to the land, the production of vegetables, then in the greenhouse, then the production of shrimp, and then the production of new products for the safety of new technologies, such as agriculture, and shrimp farming. There are very modern shrimp-raising models, and the investment costs are also quite large. Such cooperative enterprises are actively interested in the innovation of technology. There are new technologies that are applied locally to increase the production, the quality of the products, and meet the needs of the market. In adverse weather conditions, limiting the maximum number of infections is the first step that the shrimp-raising model in Nha Kinh in Loc Ha Township has achieved. From the success of the model, there are currently five models for the construction of shrimp farms. The application of new technologies, the first step, will require a large investment cost. But with the effective economic recovery, in the long run, it will bring stable profits. The problem now is that there must be standards for the technology of Nha Kinh and Nha Mang. To avoid the situation, each family does it in its own way, leading to risks when abnormal weather phenomena occur.
