Since May, affected by factors such as reduced market demand and increased diseases, the price of Penaeus vannamei in South America has generally shown a downward trend, and the price in some areas has fallen sharply, and some shrimp farmers are worried that the low price situation last year will appear again. And many strange things even make people wonder whether the South American white shrimp farming industry has encountered a similar "black swan" phenomenon.
"Recently, the situation of South American white shrimp farming on our side is very bad, the pond drainage rate is still very high, and the farmers have suffered heavy losses", these two days, a South American white shrimp buyer in Guangxi Beihai and other places told the aquaculture network that due to the high incidence of diseases, the most serious regional pond drainage rate is close to 90%, "The main types of disease are red body white and sneak death and other problems, many farmers raise semi-large specifications, it is more and more difficult to raise, water quality is difficult to control, diseases may break out overnight." At present, there are not many South American white shrimp can be listed in Beihai Fangcheng Port and other places, 40 specifications are not small, the quality of good purchase price is about 28 yuan / kg, "this price is good, but are scattered shrimp."

The situation in the Pearl River Delta of Guangdong is slightly better than that of the Guangxi North Sea, but the problem of disease is still very serious, the size of the disease shrimp is mainly concentrated in 40-60, "such a specification if it is raised smoothly, it will soon be listed, recently some of the breeding areas have more rainy weather, sometimes even strong convective weather, resulting in strong water quality changes are very serious, a little bit of unbearable shrimp is prone to problems, it is recommended that farmers still have to do more work on preventive health care." Aquaculture network learned that the current purchase price of 40 shrimp in the Pearl River Delta region is 22-23 yuan / catty, down four or five pieces a catty from last week.
The price of Zhangzhou, Fujian province is somewhat chaotic, the amount of ponds stored in several places below Zhangzhou is generally not much, some farmers have begun to sell shrimp in Qingtang to prepare for the next batch of raising King Kong shrimp, and the place where the progress of Qingtang is still very short of stock, and the price can be relatively small. At present, the purchase price of 30 shrimp in Zhangzhou is about 29 yuan / jin, 40 shrimp is about 24 yuan / jin, and 50 shrimp is about 22 yuan / jin. "In recent years, the king shrimp has been raised more and more in the Zhangzhou area, especially the Zhangpu shrimp farmers are accustomed to a stubble of white shrimp and a stubble of king kong shrimp, but from the perspective of this year's consumption, although the price of the king shrimp is OK, the circulation situation is not ideal."
Jiangsu Nantong Yancheng area has just experienced a fierce hail and rainstorm disaster in the first half of the year, especially in the Rudong area suffered heavy losses, the current farmers have basically completed the repair, "is their own shed farmers, how much cost will be repaired, rented shed farmers are not necessarily willing to repair, this kind of natural disaster is originally everyone is a victim, which is easy to produce disputes." After the disaster, some shortages of shrimp in Rudong have risen briefly, but in the past few days, with the increase in the amount of marketing, coupled with the reduction of market demand after the holiday, shrimp prices have plummeted, "the more the price falls, the more farmers are afraid of selling late and cheaper, which further aggravates the price decline." At present, the purchase price of 30 shrimp in Rudong is about 29 yuan / kg, 40 shrimp is 25 yuan / kg, and 50 is 22 yuan / kg, and it is expected that the price behind will continue to fall.
The price of shrimp in Shandong is also declining, the current storage pond specifications are mainly about 25 more, the purchase price is about 35 yuan / kg, "the price of less than 20 is relatively good, the purchase price is about 38 yuan / kg, the price of the small size is unstable." Yantai Rizhao area buyers believe that the price of small and medium-sized shrimp fell on the one hand because the market demand for less goods, on the other hand, Jiangsu shrimp on the market impact is very large, "the future of Jiangsu shrimp market will be even larger, shrimp prices are estimated to have no chance to rebound."
This year's South American white shrimp farming situation is still difficult to satisfy, the quality of shrimp fry is still very prominent, the weather environment caused by more diseases, and some other inexplicable disasters also let farmers suffer from the disaster of innocence, "I feel that this year's year is not very good, the early temperature is delayed, the shrimp growth rate is not fast, to May and so many strange things, simply put, shrimp is more and more difficult to raise, but which is the reason for it, it is difficult to analyze specifically, The situation varies considerably from place to place."
