Sun Xuemin, a shrimp farmer who gets rich by science and technology.

Although Sun Xuemin, a professional shrimp farmer in Wangwenzhuang Town, Xiqing District, has only a junior high school education, he has always carried out fish and shrimp farming through science and technology. after 22 years of hard work, he has become a leader in driving dozens of surrounding villagers to become rich.

When the reporter came to Tianjin Hengxing Fumin Aquaculture Professional Cooperative, Sun Xuemin, general manager, was standing in the water and constantly touching it with his hands. He says he has to stand in the water like this for three hours a day.

"by feeling every day, you can't find out the nourishing materials and silt at the beginning, and you can't tell them apart. After a long time, when you touch the nourishment and mud on your hand, you can feel it. It is found that the fish is soft, which is different from the softness of the mud. Sometimes you can see a sick shrimp and touch it. If there is a problem with the shrimp, we should take measures to hit it with a net. if we find something, we will feed less in the pond tomorrow. "

Sun Xuemin, 40, began to work in fishery farming with his father at the age of 18 for 22 years. At first, his father took him to the market, but later, his father grew old and gave the family farm to Sun Xuemin from 2008. At that time, however, there was a problem with fishery and aquaculture. It turned out that the big fish buyers from Inner Mongolia and the three northeastern provinces suddenly stopped coming to him to buy fish. Sun Xuemin can only switch to the Beijing market. Customers in Beijing bought more shrimp than fish, so Sun Xuemin began to raise shrimp and set fish. However, with the change of farming mode, the following problems arise. "there are a lot of shrimp in the pond, and there won't be any for a while. There is shrimp today. If it rains, there will be less shrimp the next day. At that time, a net profit of 1,000 yuan per mu of land, no shrimp, a loss of 400 to 500 per mu of land, more than 2,000 mu of land, a loss of more than 1 million yuan. "

As soon as his father put the business he had been running for many years into his own hands, he encountered such great difficulties, and Sun Xuemin had a heavy heart.

"my father worked in this industry in 1983, and I have been in this industry since 1994, and I already have feelings for it," he said. Turn around the pond every day, go into the water to touch shrimp, look at the situation of shrimp in the pond, look at the situation of shrimp, but also can not sleep, thinking about what kind of fish, can increase this output. In addition to delving into farming methods himself, Sun Xuemin went to Tianjin Agricultural College and Xiqing District Animal Husbandry and Fisheries Bureau to learn farming techniques every day, and invited experts to the pond to jointly study farming methods. He soon found his own set of scientific breeding plan.

"Fifty carps are sprinkled on an acre of land, and fifty grass carps are set. I want the big ones, but the small ones don't work. Big, sick shrimp to eat, good shrimp can not catch, there is no chance to eat shrimp. " Sun Xuemin tasted the benefits of scientific and technological culture, and since 2014, he has introduced new varieties and technologies, and carried out the promotion and application of new varieties such as Ukrainian scale carp, Zhongke No. 3 allogynogenetic crucian carp, Penaeus vannamei and mackerel, as well as pond culture capacity optimization technology, new brackish water culture model and comprehensive supporting new technology. Now Sun Xuemin does not dare to be careless in raising fish or shrimp. He walks around the pool two or three times a day, which is equivalent to walking 14 kilometers a day. He said that his biggest expense is shoes, and he has to break a pair of shoes every month.

Sun Xuemin's father said: "No matter how busy he is, he will come back to touch the shrimp to see how the pond is doing and whether he is dead or not. This is particularly valuable. It is practical to do things, and how to say and do things."

Under the management of Sun Xuemin, he has an area of 800mu, more than 23.9 million seedlings and 23.6 million Penaeus vannamei. In the process of aquaculture and production, Sun Xuemin insisted on healthy and ecological aquaculture as the direction, strictly followed the relevant standards of feed and fishery medicine in the use of inputs, and paid attention to the quality and safety production of aquatic products during the seedling release period, fish and shrimp growth period and fish and shrimp harvest period. his fish and shrimp were all qualified in the sampling inspection organized by the aquatic law enforcement departments at all levels in the city and district, and no prohibited drugs were detected. It ensures the quality and safety of listed aquatic products.

Fan Zhenzhong, director of Xiqing Aquatic Technology Promotion Station, said: "Sun Xuemin, who inherited the aquaculture industry from his father, can love your work, and learned that his father attaches great importance to science, bears hardships and stands hard work, is really diligent, works without complaining, and relies on science and technology." it has played a great role in the development of enterprises. " Sun Xuemin not only pays attention to his own development, but also does not forget to be enthusiastic about rural science popularization and public welfare undertakings. He used the existing instruments and equipment for water quality testing in the cooperative and the aquaculture knowledge learned and mastered by himself to serve the surrounding agriculture and fishery. By organizing technical training, he tested water quality and diagnosed fish diseases free of charge, helped them solve the breeding problems in the process of production, and helped more than 30 farmers around them to engage in pond farming, with a net increase of 15000 yuan per household per year.

Sun Xuemin said: "No matter how rich you are, it is useless for everyone to work in this industry. It is good to have the level to push Tianjin's aquaculture industry to a new level."
