Microporous aeration technology helps Jiangsu Jintan farmers increase income

The area of ​​crab culture in Jincheng Town, Jintan City, Jiangsu Province has reached more than 35,000 mu. In the past three years, the city has promoted acreage of microporous aerated river crabs with an area of ​​more than 5,000 mu. The average output in 2009 was nearly 100 kg, and the average yield per mu reached more than 4,000 yuan. The specifications, benefits and benefits are significantly enhanced compared with the surface. In 2010, the town developed microporous aerated river crab breeding nearly 1,000 acres.

The promotion of this technology has laid a solid foundation for the efficient breeding of river crabs, especially the long-term high temperature this year. The advantages of microporous aeration and oxygenation technology are particularly obvious. According to the investigation, the aquaculture environment using microporous aeration and aeration has obtained the water environment. The improvement is obvious, the dissolved oxygen structure is optimized, the breeding of harmful microorganisms is effectively suppressed, the content of harmful toxic substances is reduced, the stability of water quality physical and chemical factors is maintained, thereby effectively controlling the occurrence of diseases and reducing the use of crab ponds. The number of times and the amount of drug used reduce the production cost and increase the survival rate and economic benefit of the culture. As some farmers said: "This year's continuous high temperature thanks to the application of microporous aeration and aeration technology, or it will suffer."
