About the South American white shrimp many people should eat, it is a shrimp in the price of a more expensive one, its meat is very delicious and delicious, we all know that shrimp contains a high protein, so eating shrimp is very helpful for our human body to supplement protein. Nowadays, the demand for shrimp aquatic products in the market is rising year by year, and shrimp farming under the traditional model is a breeding project with small investment, small risk and fast return for farmers, so how much can it make by raising an acre of South American white shrimp? The cost and profit of raising Penaeus vannamei, let's take a closer look
Penaeus vannamei, also commonly known as white-limbed shrimp and white shrimp, was once translated as P. vannamei, and resembles Chinese shrimp and prawns, with an average life expectancy of at least more than 32 months. Adults can reach a length of up to 24 cm, the carapace is thinner, the normal body color is light blue-gray, and the whole body does not have markings. The foot is often chalky,000, so it is known as a white-limbed shrimp. Penaeus vannamei is one of the three most cultured shrimp species in the world today. South American white shrimp is native to the Pacific coast of South America, Professor Zhang Weiquan of the Institute of Oceanology of the Chinese Academy of Sciences took the lead in introducing this shrimp from the United States, and broke through the seedling barrier in 1992, from small to medium test until the promotion of aquaculture throughout the country. I Jiangsu, Guangdong, Guangxi, Fujian, Hainan, Zhejiang, Shandong, Hebei and other provinces or autonomous regions have gradually promoted aquaculture, Tianjin Hangu District Yangjiapo Town culture of South American white shrimp world-famous, has "China's fish and shrimp town" reputation, of which the technology belonging to south American white shrimp is the most mature.
Cost and profit of Penaeus vannamei
The biggest expense of breeding Penaeus vannamei is feed. It is reported that Mr. Chen's farm needs 2.24 million yuan per year for feed expenses, an average of 186,000 yuan per month. Due to the use of an aerator, the electricity cost is not small, and the water bill adds up, a total of 600,000 yuan a year. The farm has a certain scale, must be labored, according to 11 people, the monthly salary of 2500 yuan / month, plus commission calculation, the need for 440,000 yuan a year. In addition, there are 563,000 yuan of seed seeds, 450,000 yuan of fish medicine, and 600,000 yuan of pond rent, which requires 4.993 million yuan a year.
South American white shrimp is raised twice a year, of which the white pond shrimp mu yields about 500 kg / mu, about 25 yuan / kg (40 shrimp), the mu yield of winter shrimp is higher than that of white pond shrimp, up to 700 ~ 800 kg / mu, the price can reach 38 yuan / kg (40 shrimp), then the profit of one mu is 38 yuan / kg * 800 = 30400 yuan. According to the calculation of the survival rate of 80%, the annual output value of white pond shrimp is about 2 million, and the winter shrimp has reached more than 6 million, the annual output value is close to 9 million, and the input-output ratio has reached 49.9%, and the profit is still considerable.
There are some issues that need to be paid attention to in the cultivation of Penaeus vannamei
South American white shrimp shell thin fat, delicious meat, rich in nutrition, is a very popular seafood in the market, in the international, China's shrimp exports have also formed a scale advantage. In Zhanjiang alone, mariculture of White Shrimp accounts for 15.4% of the world's sales. With the improvement of people's living standards and the further development of logistics, the market area of Penaeus vannamei will continue to expand, and the potential will be further stimulated.
However, Penaeus vannamei farming in South America, like other aquaculture, faces three major risks. First, market risk, the current embarrassment facing the aquatic products market is that the sales price of aquatic products fluctuates greatly, sometimes even does not rise but falls, but the input cost is increasing year by year. In recent years, whether it is pond rent, labor, and even seedlings, feed costs are rising, thereby reducing profits; The second is disease risk. In recent years, there have been many diseases of Penaeus vannamei in South America, such as stealing death, leukoplakia syndrome, etc., and the disease not only causes the harvest to be affected. From the perspective of the industry as a whole, due to the many diseases, some farmers may take risks and use illegal fish drugs in violation of the law. Once the incident occurs, consumers will resist, resulting in an overall crisis in the industry; The risk of natural disasters, such as flooding, poses a potential risk to farming.
