"Shrimp, soldier and crab general" helped Shen Dejin get rich for the second time.

Shen Dejin is a big farmer who has been engaged in fish farming for 20 years and is a famous aquaculture expert.

In his early years, Shen Dejin carried out fish farming in Yixing, Jiangsu Province. "at that time, I raised more than 1000 mu of fish, and the fish market was still good at that time." He said. In Yixing, there are all kinds of farmers, and he has learned a lot from the exchange. Year after year, the price of fish is getting lower and lower. In 2011, when Shen Dejin could no longer raise fish, he thought of going back to his hometown of Huzhou. At this time, a series of policies to attract investment in Lvshan Township attracted him. After some consideration, he and his wife came to Lvshan Township to start a business for the second time.

This venture, Shen Dejin contracted more than 200 mu of river ponds, with a total investment of 2 million yuan, raising hairy crabs with good market conditions.

Shen Dejin had never raised hairy crabs before, but he boldly worked on the skills he learned from other masters during fish farming in Yixing. Gradually, in the process of raising crabs, he also figured out his own set of breeding experience: "to raise hairy crabs, aquatic plants are the key. If the aquatic plants are good, the water quality will be good, and the crabs will be raised well." He said. After a period of time, Shen Dejin raised crabs better and better, but he was not satisfied with this. during his inspection, he saw the advanced culture technology of crabs and prawns.

In fact, in order to improve the economic benefits of aquaculture, technological innovation is the main solution, and culture is one of them.

After returning from the inspection, Shen Dejin immediately carried out a new model of crab and green shrimp culture in his river pond. Over time, Shen Dejin had some breeding experience of his own. He said that the most important thing in crab and shrimp culture is their growth environment, which requires the selection of rivers and ponds with good water quality and convenient drainage and irrigation, with a water level of 1 to 1.5 meters. Before stocking, the pond should be cleared thoroughly to prevent wild fish from entering, so as to improve the survival rate. Secondly, putting away and releasing enough seedlings is the key to obtain high yield. The prawns are 20 jin per mu and the hairy crabs are 1800 per mu. In feeding, the feeding habits of green shrimp and hairy crab are omnivorous and animal. Feeding should be scientific, that is, quality, quantity, timing and positioning should be achieved, the quality of bait should be guaranteed, and the use of moldy and deteriorated bait should be prohibited.

In the actual operation, farmers should learn to adapt to the circumstances and be flexible. For example, when the weather changes, Shen Dejin said: "the countermeasures sometimes need to increase oxygen, sometimes to pump water from deep wells, and so on."

Of course, it is necessary to raise and sell, so that higher economic benefits can be achieved. In the process of breeding, Shen Dejin keeps abreast of the market situation and market trends. In the harvest season, Shen Dejin's green shrimp can be sold for 35 yuan per jin, even for 50 yuan per jin in autumn and winter, and 32 taels of female hairy crabs have been sold for 150 yuan per jin this year. Products are sold to Jiangsu Changzhou, Yixing and other places, through the market wholesale, rapid withdrawal of funds, can bring him 3 million yuan of wealth income every year. Five years passed quietly, and Shen Dejin succeeded in getting rich again.
