Since mid-June, the country’s Japanese shrimps have gradually ushered in a peak period of pond emergence. Due to the impact of the epidemic this year, the situation is more special than in previous years, coupled with the drag of the "new salmon incident" and the "Ecuador frozen shrimp incident". The price of Japanese prawns is slightly lower than the same period in previous years. Among them, the price of 40-headed prawns in Shandong is only in the range of 50-60 yuan/kg, and the price of 30-headed shrimps is around 80 yuan/kg; while in southern China, the price is 45. Specifications ranged from 48-55 yuan/jin, the purchase price of 55-60 head specifications was about 50 yuan/jin, while the purchase price of 40 specifications in the same period of the previous year was in the range of 60-70 yuan/jin, which was low year-on-year It ranges from 5-10 yuan.
The analysis believes that from June to July this year, the entry barriers for aquatic product markets in various regions are relatively high, and the testing is also stricter, which will have varying degrees of impact on the circulation of all aquatic product species. In addition, the sales of Japanese shrimp are mainly live shrimp. , It rarely freezes, so the acquisition is relatively more cautious than in previous years. There are feedbacks from farmers in Shandong that due to the weak impact of the new crown epidemic on the Japanese shrimp market during the first quarter of this year, the price of 20-30 heads of pond heads has remained in the range of 130-140 yuan/jin, and the first quarter of 2019 In the first quarter, the price of Japanese prawn heads of the same size was 100-120 yuan/jin. The rising shrimp prices have made farmers generally very confident this year, and their enthusiasm for seedling investment has greatly increased, so this year’s output is likely to be high. Last year, and since June, large quantities of Japanese prawns from various production areas in Shandong have been released from the ponds. Under the hedge of various factors, the current price has dropped significantly compared with May.
There have also been feedbacks from some farmers in Zhanjiang that not only the prices of vannamei, rosenbergii, and tiger prawns have been affected recently, even the prices of Japanese prawns, which have been at a relatively high level, have dropped significantly, and the market circulation has been blocked, which has also caused the market. It is not very ideal, especially the market has higher requirements for the freshness of Japanese shrimp than other species, so many buyers dare not take too much risk to spend high prices to collect shrimp. It is reported that although the catering market has recovered to a certain extent in the past two months, consumption is also much lower than the same period in previous years. Even during the Dragon Boat Festival holiday, there is almost no pull on the market. Therefore, the hotel is very strong in Japan. The demand for shrimp is not very strong either.
Although the price of Japanese prawns has recently been lower than in April and May this year and the same period in previous years, it is not in a situation of slow sales. According to the feedback from the market, the overall Japanese shrimp trading volume has continued to rise recently, especially since July, the amount of shrimp flowing from various distribution points to major markets across the country has increased unabated, and many farmers are paying close attention to the recent circulation. Speed up the opportunity to go to Qingtang, so that you can enter a new round of seedling breeding as soon as possible. According to the industry, since the beginning of 2020, although the price of Japanese shrimp in the second quarter was significantly lower than that in the first quarter, farmers did not look down on the market, generally still optimistic about the performance of this shrimp in the second half of the year, even some farmers in Zhanjiang are optimistic It is predicted that in the second half of the year, there will be two major festivals, Mid-Autumn Festival and National Day. Coupled with various domestic policies to promote consumption, the price of Japanese prawns may rise to the level during the first quarter of this year in the next few months.
According to feedback, many farmers who have cleared their ponds have begun to purchase seedlings one after another. The shrimp seedlings have not been slowed down due to the recent drop in shrimp prices. The confidence of the farmers is generally sufficient. Some farmers have already completed the seedling work in the hot and sunny weather. About half of the farmers in South China have completed the seedling. However, affected by the continuous heavy rain during the flood season, various parts of East China have been greatly affected recently, especially the coastal areas of Jiangsu and Zhejiang. The continuous heavy rainfall has caused the salinity of the water body to drop sharply. Many farmers can only delay the seedling time slightly, hoping to wait for the weather to improve. When the salinity is suitable, throw the seedlings again, try to ensure that it is safe.
The industry reminds that for farmers who have recently completed or are about to finish clearing their ponds, it is recommended to drain the ponds first for raking, plowing and drying ponds. It is best to lay a layer of 10 cm thick clean fine sand on the bottom of the pond for improvement. The bottom of the shrimp pond. Then 20 days before stocking, the whole pond was disinfected with medicine. It is recommended to spray 50kg-100kg quicklime per mu. After 3 days, drain the pond water and rinse twice to achieve the purpose of thorough disinfection. In addition, due to the relatively longer time for shrimp culture in Japan, it usually takes 4-8 months to produce shrimp, and the output is not high. It is recommended that farmers pay more attention to disaster prevention and disease reduction during the second half of the year.
Especially this year, the high temperature heat wave swept the world, farmers need to pay more attention to adjusting the water level and strengthening oxygenation. The number one enemy of flower shrimp farming, "red water", is also easy to appear during the period of 5-6 months. At that time, the water body is already eutrophication, and the reproduction speed of Gymnodinium algae is extremely fast, so the water color will become red, and it is easy to cause the yellow gills, black gills, white spots, red bodies and other diseases of the flower shrimp. However, the water color is difficult during the continuous high temperature. If this situation occurs, it is recommended that farmers consider producing shrimp as soon as possible to avoid subsequent white spots and stealing deaths, which may cause greater losses.
