Ginger, cinnamon and pepper are added to make the nose fragrant and fragrant.
This poem, which makes the food eaters drool, is a masterpiece of Liu Zai, a famous scholar of the Song Dynasty, who praised the saury at a banquet. The Yangtze River Saury (longjaw grenadierancho) has always been known as the freshest fish in the world.
Peoples obsession with eating saury after spring has made the price of saury in the Yangtze River reach new heights in recent years, which makes it difficult for rich people to taste this delicious world.
According to fishermen told the media, during the period of the peak demand before the Qingming Festival, the Yangtze River knife fish can sell for 7,800 yuan a kilogram, and even for tens of thousands of yuan in Shanghai. In 2012, at a public auction in Jiangsu, a 325-gram swordfish king of the Yangtze River sold for 59,000 yuan.
The main reason behind the rising price of saury in the Yangtze River is the sharp decrease in production caused by overfishing.
The Freshwater Fisheries Research Center of the Chinese Academy of Aquatic Sciences has published data:
The output of Jiangdao along the Yangtze River was 3750 tons in 1973 and 370 tons in 1983. After 2002, the annual output was less than 100 tons. Now the annual output is only a few dozen tons.
Faced with the current situation, the Ministry of Agriculture and Rural Affairs held a press conference on 21, announcing the implementation of the fishing ban system in key river basins in China.
Every edition notes that in the Yangtze River Basin Reserve, the Yangtze River Saury will be banned permanently and comprehensively; in waters other than the Yangtze River mainstream and important tributary reserve, a tentative 10-year ban will be imposed.
That is to say, in the next 10 years or so, people will say goodbye to this delicious mouthful.
A total ban on saury fishing in the Yangtze River
On January 21, Ma Yi, director of the Fisheries Administration and Supervision Office of the Yangtze River Basin, also participated in the press conference of the Ministry of Agriculture and Rural Areas and answered questions about the prohibition of fishing in the Yangtze River Basin.
Every edition notes that the system of fishing ban has been implemented in the Yangtze River basin since 2003. During the period of fishing ban, special management has been carried out for the fishing of three species, namely, the cuttlefish, anchovy and Eriocheir sinensis. Recently, the relevant regulations have shifted from special fishing to a more stringent comprehensive ban on fishing. This policy change has also triggered questions from journalists.
Ma Yi said that in recent years, affected by various human activities such as water pollution and ecological environment destruction, especially the competitive fishing of permissive fishing species such as Yangtze River squid, anchovy and Eriocheir sinensis, the annual yield of squid has dropped from 4142 tons to less than 100 tons, the yield of anchovy has dropped from the highest to less than 10 tons, and the yield of Eriocheir sinensis has also dropped to less than 100 tons. u3002 It is necessary to stop issuing special fishing licenses for Scorpion, Phoenix and Eriocheir sinensis in order to implement the comprehensive fishing ban policy in key waters of the Yangtze River Basin.
Ma Yi also pointed out that every year before and after the Qingming Festival, the high-priced knife fish caused great social repercussions, which fully illustrated that the exploitation and utilization of the swordfish, anchovy and Chinese mitten crab had exceeded the carrying capacity of species resources, and the relevant special fishing system needed to be adjusted and improved urgently.
However, the eaters need not be too sad. In the future, with the recovery of fishery resources, the Yangtze River saury may be lifted in 10 years. According to expertsestimates, the reproductive cycle of fishes in the Yangtze River is about 3 years. If a 10-year ban on fishing is implemented, most fishes can complete three generations of reproductive cycle, which can fundamentally curb the trend of sustainable decline of fishery resources in the Yangtze River Basin.
Ma Yi stressed that with the improvement of the ecological environment of the Yangtze River and the gradual emergence of the effect of the ban on fishing, the fishery resources of the Yangtze River will also achieve restorative growth after a certain period of time. At that time, the Ministry of Agriculture and Rural Affairs will organize and implement the effective protection and rational utilization of the fishery resources of the Yangtze River in various ways, such as the prohibited fishing area, the prohibited fishing period and the special concession fishing, according to
Pre-Qingming Festival sale price
Like the salmon that Westerners like to eat, the Yangtze saury is also one of the typical migratory fish species. The reproductive season enters freshwater areas from the estuary area and goes up the main stream to the production farms in the middle reaches of the Yangtze River for reproductive migration. After spawning, the parent fish dispersed in freshwater to feed, and slowly returned to the estuary and offshore. The young saury of Yangtze River also migrated to the estuary area to fatten.
Every year from February to March, parent fish enter the river from the sea and migrate upstream for reproduction. When the reproductive season is in March and April every year, the spawning population enters lakes or tributaries along the Yangtze River or spawns in the main stream of the Yangtze River.
Every year before the Qingming Festival, it is precisely when the Yangtze River Saury is hard to find a knife and has repeatedly set record prices. At this time, the saury began to swim to the estuary of the Yangtze River, because the fresh water and sea water at the junction of the rich bait, so the meat is particularly fresh and tender.
The highest price of saury in the Yangtze River can be 7,800 yuan per kilogram, a fisherman said in an interview with the media.
Nan notified the owner of Merlin Chunxiao, a famous Jiangxian restaurant, that in the Qingming Dynasty in 2017, the most expensive saury in their restaurant was 6,680 yuan per kilogram. Many foreign customers still came to visit the restaurant and ordered to eat Yangtze saury.
However, with the Qingming Festival as the watershed every year, the price of Yangtze saury dropped rapidly after reaching its peak. It is understood that in the Nantong section of the Yangtze River in 2017, on April 3, fishmongers came on board to collect knife fish at a price of about 3,000 yuan per kilogram, while on April 4, the price fell to 1,700-1,800 yuan per kilogram on the Qingming Festival.
In addition, because of the small stock of knife fish, the amount of catch fluctuates greatly, which may lead to sharp price rises and falls. For example, in March 2013, Xinhua News Agency reporters in Shanghais largest aquatic wholesale market Tongchuan Road aquatic market survey found that the price of knife fish fell from the highest price of 8,000 yuan per kilogram in 2012 to 400 yuan.
The saury fishing season retreated from Dongting Lake to Jiangyin
Now the catch is no longer significantly reduced, because the fish are almost gone. Zhao Jindong, member of the CPPCC National Committee and academician of the Institute of Aquatic Biology of the Chinese Academy of Sciences, explained that the catch of fish in the Yangtze River has been like a downhill curve for decades and is now at the bottom, so it tends to be flat.
It takes at least two million years for the Earth to make a species, and it may take decades or even years for humans to destroy a species. Cao Wenxuan, director of the Academic Committee of the Institute of Aquatic Sciences of the Chinese Academy of Sciences, and 14 other academicians jointly drafted a proposal.
A large number of historical data prove that from the Yangtze Estuary to the Dongting Lake in Hunan Province, it has been the origin of Scorpion from ancient times. Authoritative data show that in the past, the production of Scorpion japonicus accounted for 35% to 50% of the natural fishery in the Yangtze River, and the proportion of Scorpion japonicus in the Jiangsu section was as high as 70%. This state of affairs lasted until the 1970s.
By the end of the 1980s and the beginning of the 1990s, there were almost no migratory saury in the section of the Hubei River in Hunan Province. Two or three years later, there was no Jiangxi section. Around 1996, fishing information was difficult to form in the section of the Anhui River. Jiangsu section is also unavoidable. In 1997 and 1998, first of all, there was no fishing information in Nanjing. Later, the production of Jiangdao in Zhenjiang and Yangzhou also decreased sharply. By 2011, the migration route of saury has been greatly shortened to form the upstream of the fishing season, only to Changshu and Jiangyin in Jiangsu Province.
The sharp decline in wild fishing has also made some enterprises and scientific research institutions look forward to the artificial cultivation of saury, although up to now, the market price of cultured saury has not been successfully reduced. Xu Gangchun, Chinese Academy of Fisheries Sciences, explained that the commercial specifications of saury are usually more than two or two, but now the commercial rate of large-scale artificial breeding of saury is less than 20%, and the cost of farming is almost the same as the price of saury caught in the Yangtze River. Through several generations of domestication, the stress response level of saury will be significantly reduced, and the degree of domestication will be improved, which will greatly improve the survival rate and commodity rate of saury farming, and reduce the cost of farming. Xu Gangchun believed that the commodity rate could be stabilized at more than 70% after two generations of cultivation of fine varieties.
