"In this 500-square-meter shrimp seedling workshop, 1.6 million shrimp seedlings have been cultivated. After these shrimp seedlings reach the commercial shrimp specifications, the estimated output value is 750,000 yuan, and the net profit is 150,000 to 200,000 yuan." On March 10, Panjin Photosynthesis Xi Wenqiu, head of the Penaeus vannamei project of Crab Industry Co., Ltd., told reporters.

Penaeus vannamei has delicious meat and high nutritional value, and is favored by the market. At the same time, because of its short breeding cycle, high yield, good benefits, and suitable for high-density breeding, Penaeus vannamei has become an important species for farmers' aquaculture. However, due to factors such as seedling quality, climate change and diseases, the production and benefit of P. vannamei farming are unstable.

In order to solve the problems in the cultivation of Penaeus vannamei, the photosynthetic crab industry began to try factory greenhouse cultivation last year. Technical personnel carry out scientific breeding and standardized management. The water temperature and water quality in the breeding ponds are tested every day, disease prevention work is done well, and at the same time, regular and quantitative feeding is carried out to promote the healthy and rapid growth of Penaeus vannamei, and improve the yield and quality. Photosynthetic Crab Industry has tried two crops of prawns in a workshop with an area of 2,300 square meters, with an output of 11 kilograms per square meter, and the test has been successful.

This year, Photosynthetic Crab Industry has expanded the scale of Penaeus vannamei farming and built commercial shrimp farming workshops and farming greenhouses. In the breeding workshop, the reporter saw that canvas breeding ponds were neatly arranged. Each pond is 8.5 meters in diameter, and there are more than 100 in total. The shrimp seedlings grow to 2 to 3 cm in the workshop, they will be moved to the breeding pond, and after more than 2 months, they can be sold on the market. Photosynthetic Crab Industry's new shrimp breeding greenhouse is also in full swing. After the completion of the greenhouse, a breeding pond will also be placed to breed Penaeus vannamei.

Factory farming is the use of modern industrial methods to control various factors such as water temperature, salinity, water level, and feeding ratio in the aquaculture pond, creating an optimal survival and growth condition for shrimp, breaking the aquaculture industry. situation. Compared with traditional farming, factory farming can raise two crops a year, doubling the output. At the same time, you can choose the time to market to achieve off-season sales, and the price is a lot higher.

Photosynthetic Crab Industry has realized the "factory-like" cultivation of Penaeus vannamei in Panjin, exploring a new development path for Panjin's agricultural industry. Photosynthetic Crab Industry will provide Panjin farmers with Penaeus vannamei seedling services, and provide breeding technology, leading more farmers to become rich.
