Suzhou, Jiangsu Province, Nanmei White Shrimp farmers have become rich.

Penaeus vannamei was introduced in 1988 and has been cultured in China for 23 years since it was introduced in 1992. From 2012 to 2015, the water surface of the whole country has basically remained unchanged, but the yield is getting lower and lower. In 2015, only 30% of farmers in Jiangsu, Shanghai and Zhejiang provinces made a profit by raising Penaeus vannamei. It is a well-known fact that the environment, weather, disease and other factors have been affecting our farming profits. For farmers who have entered the industry, how to achieve satisfactory returns and profits in such an environment?

Let's follow the Tongxin News reporter to take a look at the Tangkou of Jiangsu aquaculture expert qu Tao, and let him tell us that as long as we change our breeding habits, we can use our hard work to make profits and improve our lives.

Boss Wang's shrimp pond

Qu Tao's Tangkou is on the edge of Yangcheng Lake. A few days ago, the reporter followed the expert inspection team of aquaculture experts and came to his Tangkou. From 30 mu of aquaculture in 2012 to 70 mu of Tangkou today, in terms of breeding time and scale, qu Tao is undoubtedly only a newcomer in the circle of Penaeus vannamei, but he has made money every year in the past four years. In addition to choosing to cooperate with Tongwei, what is more important is that qu Tao is good at learning and practicing and dares to try.

"that year, I was still a pig feed salesman, sweating every day with the goal of making more money and bulging my pockets at the end of the month. Later, after careful consideration, I came to Yangchenghu Town, Suzhou. From a business staff to a dealer." Recalling his own breeding experience, qu Tao said that in the process of breeding in recent years, he has been constantly thinking and exploring a culture model suitable for himself, and looking for a new way out for white shrimp culture.

How did he do it these years?

Qu Tao said that attention must be paid to the treatment of sediment before releasing seedlings. After the dried shrimp pond is sold, measures such as flat pond and ploughing are adopted, which are beneficial to organic matter decomposition, pond bottom restoration and natural sterilization at the bottom of the pond.

Most farmers think that high density brings high yield, but high density is closely related to pond conditions and culture management. In today's white shrimp culture, the biggest bottleneck affecting the profit of white shrimp culture is the culture success rate, and a reasonable stocking density is conducive to the improvement of culture success rate.

Take the two ponds in front of qu Tao as an example, each 10 mu and 20 mu of the pond released 800000 desalinated seedlings on April 16 this year. By the end of August, the yield of white shrimp was 14192 jin, the average specification was 40, and the yield per mu was 700jin / mu. Although the yield of Tangkou is lower than that of other Tangkou which is more than 1000 jin / mu, it is convenient for Tangkou management and water quality control in the whole culture process, and the risk is low.

At the same time, qu Tao adopted the mode of raising green shrimp in white shrimp ponds. Qu Tao introduced that the release time of green shrimp is in mid-late August, and when white shrimp is sold at 2 / 3, the stocking density of green shrimp is determined according to the output of white shrimp. This year, there are 20 mu in two ponds at the gate of qu Tao, with a total of 200 jin of green shrimp, with specifications of 3000 tails per jin.

The key to the success of aquaculture can not be separated from the good aeration of the pond. The reporter in Tangkou of qu Tao saw that it was equipped with one microhole aerator, eight water tankers, two surging machines and four impeller aerators. The power of Tangkou aeration equipment is allocated to 1.05KW/ mu. "normally, my microhole aerator is on all the time, and the start-up time of the surge machine and water wheel aerator is from 11 am to 5:00, and the turbine is from 6pm to 8:00 Qu Tao introduced it.

In the choice of animal protection products, qu Tao said that the products he chose were all products produced by guaranteed manufacturers. Under normal circumstances, regularly divert water and cultivate algae to replenish bacteria according to the cycle (7 days / time). In the early stage of culture, Tongwei active algae source + gold peptide was used to culture algae, and in the middle and later stage of culture, emphasis was placed on replenishing bacteria, and feed companion 1 + lactic acid bacteria was used to decompose residual bait feces. In terms of feed feeding, in addition to the same feeding rate and feeding times as everyone else, we also take Qishen immune powder + hepatobiliary health + Tongwei Duowei for a long time. After the launch of Shrimp Ganqiang product, we began to feed Shrimp Ganqiang.

"before the weather changes, especially when the weather is forecast to rain, sprinkle Tongweidouwei + Alkaline Kangsu in advance to increase the stability of the water body. After rain, immediately sprinkle anti-stress products, stress detoxification or detoxification pioneer. Before shelling, the shrimp is sprinkled with trace elements (alkaline kangsu) at about 6 p.m., mainly replenishing calcium and magnesium ions in the water. After selling shrimp, use Nabijing, which has strong stability and long time, to prevent the spread of harmful bacteria and is conducive to the recovery of shrimp. " Qu Tao said that farmers all hope that farming can make money and have a return on investment. combined with their own conditions in Tangkou, they can improve the environment of Tangkou sediment, increase dissolved oxygen in Tangkou, and choose guaranteed animal protection products to transfer water on a regular basis. Profits are no longer far away.

Today, qu Tao is not only famous for raising shrimp on his own, but also drives a large number of farmers to grow shrimp with him, driving everyone to become rich. In the process of exchanging breeding experience with the members of the expert group, qu Tao was good at thinking, dared to innovate and dared to try.
