After many failed farming seasons, Mr. Nguyen Viet Khanh (born in 1976, in Dan Truong commune, Nghi Xuan, Ha Tinh) boldly invested nearly 4 billion VND in closed-technology shrimp farming in greenhouses, which initially showed much promise.

Mr. Khanh's closed-technology shrimp farming model in a greenhouse has an area of ​​nearly 5 hectares.

Before learning about this new shrimp farming technology, Mr. Nguyen Viet Khanh had been involved in high-tech shrimp farming on sand for more than ten years. Mr. Khanh shared: "Previously, shrimp farming was not very effective due to the inability to manage the pond environment. During the rainy season, when encountering heavy rains, shrimp were "shocked" by heat and died en masse, causing heavy losses. After visiting and learning, in September 2022, I boldly invested nearly 4 billion VND in closed-technology shrimp farming in greenhouses to limit risks due to weather and disease as well as to take the initiative in the season."

The model has a total area of ​​nearly 5 hectares, divided into 7 round tanks with steel frames and roofs, each tank is about ^700m2 wide. Inside the shrimp farm, an aeration system is invested to provide enough oxygen during the farming process along with a circulating water filtration system.

When the shrimp reach a size of 40 - 50 pieces/kg, they are harvested.

In December 2022, Mr. Khanh conducted the first trial crop indoors. This crop, he cautiously released a small amount of shrimp to monitor the shrimp's growth. However, due to lack of experience and many other factors, this shrimp crop, the model suffered a loss of more than 300 million VND.

Learning from experience, he continued to release nearly 1 million shrimp larvae in the summer-autumn crop of 2023. Thanks to low density farming, from 100,000 to 150,000/tank, combined with compliance with technical process factors, he won big this crop. With an output of 14 tons, revenue of more than 1 billion VND, after deducting expenses, he made a profit of nearly 700 million VND (after nearly 4 months of farming).

According to Mr. Khanh, shrimp is a species that is sensitive to the weather and susceptible to diseases, especially in the early stages, so raising them in a closed house to ensure their "health" during this stage is a decisive factor in the success of the crop. Ha Tinh's weather is quite harsh, so raising shrimp in a house with a roof helps stabilize the water source in the winter, and in the summer, there is a net to ensure ventilation.

At this time, Mr. Khanh is focusing on taking care of winter shrimp farming. This is a difficult farming season but brings high economic value. After the recent heavy rains, thanks to the roof, this farming season was not affected, the shrimp have reached the size of 80 - 90 shrimp/kg, expected to be harvested in nearly 2 months.

"To successfully raise shrimp, in addition to investing in infrastructure and applying advanced technology, the quality of the seed, compliance with disease prevention procedures, and care techniques are the most important factors. In particular, raising shrimp in greenhouses has a clear advantage over outdoor farming thanks to water treatment, controlling unfavorable weather factors, minimizing diseases, and ensuring waste collection" - Mr. Nguyen Viet Khanh shared more.

Mr. Le Ba Thuan in Phong Dien district, Thua Thien Hue province visited the model.

Mr. Nguyen Viet Khanh's indoor shrimp farming model is attracting people from inside and outside the province to visit and learn. Mr. Le Ba Thuan in Phong Dien district, Thua Thien Hue province said: "I am raising 4 hectares of shrimp using the outdoor method but it is very precarious, losing more than gaining. Knowing about Mr. Nguyen Viet Khanh's model, I came to learn about investing in raising shrimp in greenhouses. Through observation, it shows that this model is suitable for weather conditions in some provinces in the North Central region to minimize the negative impact of external factors on farmed shrimp."

Mr. Nguyen Viet Khanh's closed-technology shrimp farming model in greenhouses is a new technological solution, helping farmers cope with unpredictable weather changes while improving efficiency on an area. However, businesses and shrimp farmers need to carefully study the farming process and techniques when applying this model appropriately to avoid risks in production.
