Yangtze saury, generic long-jaw anchovy, also known as C. nasus. The flat side of its body length, abdominal silver and greasy, so named because of the shape of a knife. Distributed in the Yangtze River and coastal brackish areas, the reproductive season, into the fresh water from the estuary, along the middle reaches of the Yangtze River upstream to the middle market for reproductive migration, far up the Dongting Lake, and some main stream in the spawning rivers, but also into the tributaries and lakes through Park to lay eggs. Broodstock after spawning in fresh water feeding dispersion and gradually slow back down the river estuaries and coastal waters to finishing. Long jaw anchovy juveniles migrate downstream to the estuary area is also finishing. In winter, no long-distance migratory jaw anchovy, and gathered in the depths of winter offshore. Is typical of migratory species. Asked the price of the Yangtze River saury: million behind the bitter vegetable ecological costs Length and the side flat, silver belly and greasy, the fish got its name because of the shape of a knife. Yangtze saury, generic long-jaw anchovy, also known as C. nasus. In contrast, people are more familiar with it belong to another --- anchovy fish, which is commonly known as Feng anchovy, and C. nasus, as close as the two fish, usually near the estuary habitat in the shallow eastern China, an annual spring and summer lay eggs between the prospective water, is typical of migratory species. Residents of many cities along the Yangtze River, the Yangtze River known as saury knives, they know, compared to deep-fried and placed in tin cans, sixty-seven yuan for a box of anchovies sold, Jiang Xiao soil knife worth of difference has been --- a hotel in Jiangyin, three knives gather a Jin Jiang, steamed into the disk, price of a million, this was the latest price. Some older ones Jiangsu know, this huge spread to form in the previous 20 years. Once upon a time, along the city's people, in the Ching Ming Festival several times how much you can taste fresh, like the Mid-Autumn Full Moon, as Shangju eat crabs. "Pleases to see the net out of Yin Dao" is the sentence Su Song, Qing Li Yu is known as "Spring Gala wonderful thing." Historical data show that production has accounted for C. nasus Yangtze River fishing catches fish natural 35% to 50% in Jiangsu Jiang segment accounted for less was as high as 70%. Now, ordinary people of the southern spring and fresh river knife has become a luxury custom . In 2005 a Shanghai press in the article wrote: "eat the Yangtze River saury? If asked to take the issue to young people today, I'm afraid the problem with: saury seen it?" May 1, along the Yangtze River the hands of the saury fishing license fishing license expires, the formal end of this year's season of saury. Up to now, in 2005 the total catch of saury the Yangtze River there is no exact statistics, but the market price has to prove that last year this figure dropped a foregone conclusion. From the Chinese Academy of Fishery Sciences Freshwater Fisheries Research Center, a data show that older along the Yangtze River 1973 Knife River production was 3750 tons, 370 tons in 1983, 2002 has been less than one hundred tons production. "This is not a linear decline was decreased exponentially, proving that we Coilia has been to limit the use of resources." Freshwater Fisheries Research Center Resources Research Office, Shi Wei, Gang said. Within two weeks, this reporter visited various cities of the Yangtze River showed that the decline geometrically catches behind the Yangtze River saury expensive, and operators of fishing in terms of a loss rather than gain; in trying to save the saury population the eyes of scholars, the real pay a painful price, the entire Yangtze River ecosystem. Chen Chu raw saury fishing season Chen Chu of Health admitted that the saury season, both he and his brother to a total of 300 pounds was caught saury, only the equivalent of the last century, catches of 80 subnet. April 26 morning 7:54, a 30 cm long knife was pulled out of the river, river, the sun shining fish quickly tap water, then, the card hanging in the sky-line of the fish, it is hard to head torsional river, body Comparative Study and Integration, a second bent rigid semicircle. This is Chen Chu Changshu Health fishermen caught the first day of the Yangtze River saury, two hours ago, he and his brother Chen Chu root of the drive a diesel-powered fishing boats, fishing Xupu starting from Changshu, east into the vicinity of Su Tong Bridge section of the Yangtze River. This is the raw 62-year-old Chen Chu river knife, a favorite fishing ground. 7:10, Lufeng Ying Chen Chu by his wife and small son, Chen Liang, a gill net would be thrown into the river between the two ships. After five or six minutes, 500 meters under the big net drag in the two ships, Shun Jiang Liu curved forward slowly drag. Shallow river where emergency has always been the saury Jiang Road, 3 cm square mesh gill net direct river bottom, just enough to intercept the fish. This morning, repeated twice in the net drag action, Chen Chu Health brothers got their season in the biggest catch of the saury: A total of 159 Knife River Treaty size 30 kg. But I do not like Chen Chu students saw the process as exciting news, the harvest too late, now is the season river city knife, fishmongers are given the purchase price is less than one-tenth of the peak. A month ago, the Yangtze River will see the fishermen who sail boats sped from the fishmonger, who captured every river in search of a fishing knife, out of a Jin 700-1000 yuan's high, while the prevailing market on Jin Jiang knife was once a price of 2,000 yuan. But by that time, Chen Chu students who can only be waved red dealers. March 15, the saury catch of a lifetime of elderly people scattered the saury quarter of 2005, the first net. Unprecedented high prices on the market, so that he seems to face a maximum bet of gambling, "Slow Boat to twist the throttle, my hands are a little shiver." Chan Chu Chan said. That day, when more than 500 meters long gill nets from the river slowly pulled out, Chen Chu River Health fishing knife to see his career in the first empty net, to the day, he sprinkled a total of 4 network, all Space Network and, saury without a trace. After 8 days, still nothing, 9 days, he appeared in gill-line end of 2005, the first river knife, but all that day's harvest, only a mere 2 pounds and 8 two. "This is the year have not been any thing. My feeling is that this year's River Knife half less than last year at least." April 26, Chen Chu raw saury quarter of this year's poor start continues to bear a grudge, his face calmly looked down, under the right index finger unconsciously about paddling SHIP. At this time son, Chen Liang received the thread of her conversation, "my dad a few years of river fishing knife, this had never come across an empty net. You can imagine his heart? A farmer planted a year and in the end crop failure , what would feel? "In fact, when reporters after the Chen Chu of Health on April 26 informed Changshu harvest fishery station, a staff member, the other party could not believe it," there so many? When this fish is the most recent days, but one day catch of 10 pounds a boat has become regarded as a good income. "The fishery officers surprised the grounds, this spring, Shanghai, Jiangsu and Anhui issued a number of urban media saury" missing "exclaimed, Shanghai," Wen Wei Po, "April 1 report: Nan Li Jingui fishermen from fishing from the early February dozens of saury fish have only been 5 days. Chen Chu students admitted on April 26 this year the harvest was his rare good fortune. The saury season, both he and his brother to a total of only 300 pounds saury fishing, only the equivalent of the last century, catches of 80 subnet. The Lao Yumin mind, there is a clear production of table knives Jiang: "Before 1973, we are also two boats fishing river knife, but the ship was rowed the boat. Net were one-third length, quality and well, catch a fish, will make a net. But before Tomb Sweeping Festival, one net, to catch at least 200 kg river knife, when up to 600 kilos. "Knife River up to 1973, a master of our village before and after the month during the Ching Ming Jiang jin grabbed a knife, I caught that year to 6,000 pounds. I caught a river through the largest 6 double knife, when the river knife even sub-4 pound fish was enough. "" Since 1973, a small river knife year after year, year after year and thin. the fastest decline since 1995, but there is forty or fifty year subnet pounds, in 1997 only network subnet to two to three pounds of the. "" by the year 2002 before Tomb Sweeping Festival, subnet spread down to only one of the two. That knife for the price of Jiang Meng Wang on the turn, fishing The purchase price on a 1 kg 500. In 2003 and 2004 reduced the number of river knife was not obvious, but the purchase price rose clear and bright fishing boats around 650 per catty. " Knife River astronomical source Fishing Town, Jingjiang City, Jiangsu woman farmer's market, two months ago, Knife River in 2005 an important source price. The market many times a "grab fish" storm, some people even fight. April 29 morning, fishing from the dozens of kilometers of Health Chen Chu Jingjiang City in Jiangsu woman fishing town farmers market, each saury fish stores still sell at this time, more than 2 saury price of two in every hundred Jin above. This seemingly quiet, Jingjiang City, the largest farmers market, two months ago, Knife River in 2005 an important source price. "The end of February and early March, I've sold a knife Jiang yuan per jin 1800,1700. Such a good market for a week, 300 higher than last year to block." Stir a hand stall Liu the saury ice body, and some excitement recalls. During that time, every day, many cars parked in the market door sedan. From Shanghai and Nanjing and other places to buy authentic to the owners of the Yangtze River saury, but many of them will be "persuaded to go," because of a serious shortage of river knife, a high price then it is difficult to buy, buy fish also rely on "relationship." That is what the fishermen born Chen Chu chagrin of time space network, obviously, Jiang knife market and fishing boats on the river has a direct cause and effect. The reason why the wealthy patrons gathered fisheries woman farmers market buy "authentic" Jiang knife, the reason for the migratory habits of the Yangtze River on saury. Jingjiang since ancient times, "saury town" reputation. Allegedly, the tide into the furthest point of the Yangtze Estuary just in Jingjiang Newport, Knife River since ancient times, where are gathered together in groups, and, when the migration now, and gradually reduce the salt fish was appropriately contained, in addition to gonadal development began to accelerate, so section of the river here by the middle of the most beautiful river knife taste. Local market sources, Jingjiang City, Jiangsu produced in Newport this year is very little actual knife, most sword Jiang from Shanghai and Jiangsu other section of the river come together and shoot the "Jingjiang saury" to Bo high prices. What is more, the Shanghai sea fishing knife and Chaohu Lake and other places fishing knife, into the local river in the "gold plating", posing as river knife. As the name suggests, the sea offshore fishing knife saury not migratory, and the lake knife, a long life in fresh water river in the same knife, the real diners are aware, Knife sea, lake and river knife blade shape similar to, although its taste as good as night and day value has no match. Another stall holders told reporters that Jiang knife just listed this year, the market many times a "grab fish" storm, some people even fight. Some aquatic shop knife river was once the auction scene. It was confirmed that the most expensive pound more than the 2,000 yuan Jiang knife. This spring, river knife worth the high jump ever become a common phenomenon along the Yangtze River. Several local media have reported this: March 15, Nanjing, Jiangsu knife against previous years, the retail price of a gradual decline after the listing of the norm, as amended, weight 150 grams (3 two) beginning from the listing price of 2,400 yuan / kg soared to 3,000 yuan / kg, _set_ting a new high of nearly five years. March, Suzhou River on the market call for knife 4,000 yuan a kilogram of the price. March, the Shanghai market, Jiang knife break 4,000 yuan a kilogram. April 12, Tongling, Anhui Province on the market, "Yangtze River saury" has been "full listing", and 3,600 yuan out of the astronomical price of a kilogram. Although this river knives are experts suspected frozen Chenhuo next year. "Clear and bright before the fish bones as soft as cotton, fish bone after Ching Ming as hard as iron," the appetite of diners River Knife market is an important determinant. Since ancient times, Jiang knife, shad, blowfish and that "the Yangtze River Sam Sun," because the saury to market first, so Sam Sun of the first column, but this fine barbed fish very much, so hard and soft fish bones before and after the change during the Ching Ming , greatly affect the taste. A passion for diners to eat in Nanjing river knife description: "before Ching Ming Jiang knife, meat tender and smooth, delicious non-party matter, Fishbone mouth. That people just want to close their eyes feel fine chemicals, intoxicated. "There are also accounts of Li Yu Qing gourmet:" Fresh fish, carp and sturgeon are tired, the anchovy is more to chew more willing to release almost can not feed their families. "In recent years, pre-Qingming Yangtze River knife into the city's most fashionable One of the gifts, but most reflect its value, or restaurant meals in a steamed Stanford saury. And separated by a river, Jingjiang City, Jiangyin City, the economic strength among the nation's counties and cities in the forefront of the hundred, here a few museum staff said Jiang, Qingming ago, the museum a steamed River Knife price was as high as 6,000 yuan or more. He said a knife generally Sheng Jiang 3, weighing about 1 kg or so. Information, before the Ching Ming Jiang knife fish, hectogram fat 16.8 g, protein 14 grams, 1.1 grams of phosphorus. The beauty of steamed River is the knife, into the tray is not to the scales, high temperatures, the fish drops into the oil beads microlepis, even more delicious. Industry sources said that in the spring of Jiangyin, a luxury hotel knife price per plate steamed river above the million. Not only that, Jiangyin, a few museum boss Jiang, Qingming, he knives every day a source of worry for the river, because the competition to concentrate on each hotel in the fish body: "Which hotel today authentic river knife, Which business is like, because it means that rich patrons will come. "Media reports indicate that similar competition was also the case in Shanghai, Nanjing, Suzhou, Wuxi, Changzhou and Nantong. The cost of a fish catch Health Chen Chu Chen Chu brothers are caught with 300 kilos of root saury 2 million yuan were sold, but the two boats diesel consumption value of 4,000 yuan. This points down, only points for every family about 8,000 yuan. Which is 8,000 yuan, Chen Chu to students for half of all life, a family of three. April 26 noon, in the Soviet Union often fishing 19037 fishing boat deck, Chen Chu of Health pointed to the river is divided into three groups of medium and small knife to his day's earnings reporters estimate. 2 more than the two major knife 56, both of 14 pounds 2, 60 yuan per catty; a two and a half to 2 ounces of the 65 river knife, about 10 kg, 15 yuan per catty; a two and a half below the 38 small river knife , about 4 half kilogram, 5 yuan per catty. Quarter of 2005, one of the biggest catch of saury, Chu Chen brothers brought about thousands of students of revenue, from the amount of speaking, which sell for less than 30 pounds of fish in late March and harvested 2 pounds 8 for his first two rivers knife income. Knife river was 700 yuan per catty, subnet sold 1,400 yuan. This spring, students Chen Chu Chen Chu root of the brothers are caught with a total of 300 kilograms of saury sold 2 million yuan, but the two boats diesel consumption value of 4,000 yuan. This points down, only points for every family about 8,000 yuan. Which is 8,000 yuan, Chen Chu to students for half of all life, a family of three. Six months later, their brothers will once again sail into the river, Feng anchovy fishing. Now, Chen Chu students face another problem is that the cost of shipping and the network can not be recovered. "I regret buying this the net." Chen pointed to the white fiber silk goes into the gill nets, this is his life in the most expensive to buy fishing nets, worth 6,000 yuan. A fisherman on his way, having this special saury fishing nets, have been just as good soldiers want to have a gun as natural and necessary. 4 years ago to 30-year-old son to get married Chen Liang, Chen Chu, 59, a handful of students decided to fight, then spend 4 million on the purchase of a used small diesel engine steel fishing boat, while the acquisition of this expensive teeth The gill nets. "I caught a lifetime river knives, knives Jiang know little of these years, year after year, but I never expected decline Jiang knife so fast." 4 years ago, Chen Chu Health Net purchase of the ship, a seasonal river knife income, at least twice now. This time he heard from another reporter mouth bad news, since the spring of 2002, the Yangtze River fishing ban has been implemented, thousands of copies each year fishing concession card river knife, much in the first two years fishermen favor. This year, there is a considerable part of the fisheries sector to remain in the hands of staff. In Changshu, 29 to 14 cards only. Chen Liang with a fisherman son inherited his father had intended, but now he changed his mind: River knives have been a few years can be arrested, while the number of C. mystus also decreased year by year, fishing has been unprofitable, must seize the time "into the plant." "Young people no one important fishing village, the fish will starve to death." Liang-like response to a reporter, he pointed to the river shore waving plants, the river's sand boat. Knife River is far more than missing With the column "Cheung Sam Sun," the Yangtze River shad, in the Yangtze River has been missing for up to five or six years. The process is also in steep decline in recent decades, migratory routes shortened, and then disappear. Chen Chu of Health in charge of management of fishing fishery station in Changshu City, Chang Chin-hua, deputy chief also revealed disturbing figures: In 1973, the Suzhou River Knife middle section of the river about 400 tons, only to produce 70 tons of Changshu, 2004, Changshu only outputs of about 2 tons of river knife. "However, to the late 80s, early 90s, Hunan and Hubei section of the river essentially no migration of the saury to the. Two or three years, in Jiangxi, is gone. About 1996, Anhui section of the river has shaped Fishing was not a hearing. Another fish is comparable with the column "San Xian Yangtze River" of the Yangtze River shad, the fish in the Yangtze River has been missing for up to five or six years. The process is also in steep decline in recent decades, migratory routes shortened, and then disappear. "Poor fish" are of no return Qin'an small boat with windows that, if not the talismanic --- Qingming Jiang knife after "bone hard as iron", which is no longer a delicacy, it may already extinct. "From the perspective of a fish, migratory river knife is very tragic. You think about it, spring, river knives were struggling to swim into the Yangtze River, is to love, spawning, breeding their offspring. But human beings, but in Zhang Da thousand river network, they had time to catch them before breeding! "71-year-old associate professor of Nanjing University, said Qinan small boat with windows. 70,80 at the turn of the last century, Life Sciences Qin'an small boat with windows in the South, led by Professor Yuan Chuanmi, participation in the domestic river knife earlier studies. "This fish is very hot-tempered character, OCS arrest, unlike other fish, as quiet, but not willing to struggling, oxygen consumption, a few minutes died. We do not know that the poor fish in the end death is hypoxia, or scared to death, in short, Yes that is wasted step. "fishers of Health Chen Chu also told reporters that in addition to the regular fishing boat, the river there are many irregularities in the small trawl nets Shenshui Wang, and Plug nets, some network mesh is very small, the size of the aquatic fish pass to kill, and even eggs can be tangled. Qin'an small boat with windows that, if not the talismanic --- Qingming Jiang knife after "bone hard as iron", which is no longer a delicacy, it may already extinct. This is the nature river knife left a way out. At this time, Jiang knives have a chance to swim to spawning grounds to complete reproduction. However, when the eggs into a river fish knife, return to the way the sea is also extremely difficult. Another scholar in 1989, specifically mentioned that field eel frenzy. At the time, the skyrocketing price of domestic eels, artificial eel be huge profits, while the artificial propagation of eels can not solve. For a time, the Yangtze River net, plug network clouds, crazy catch eel. "Eel net mesh, small enough to be tangled up in the granular particles slightly larger eggs. As eel fishing season and return to the sea river knife seedlings some time overlap, for a time, numerous river knife was hanging dead in eel seedling online , was eventually thrown away as waste. " Base personnel asked fishery The face of scholars should ban knives river views, Changshu City, fisheries station made a grass-roots workers to ask: "did not catch light for thousands of years, it will be able to light-harvesting two or three decades?" He believes that reduced river knife main cause of water pollution in the Yangtze River. "It now appears that we have over 20 years ago did not play a role in the appeal, Jiang knife today, is said to be in our big mouth. I am sad because it was entirely avoidable." Qin'an small boat with windows said that the last century the late 70s, early 80s, South teacher of Life Sciences, 5 river knife five or six years, then felt a small river year after year the number of knives. Therefore, they share many scholars in a variety of domestic limited fishing at the river called knife Animals have talked to the State. The reality is, the relevant state departments have taken note of the Yangtze fish resources. In 2002, the introduction of the spring cut the Yangtze River, the Yangtze River and the phoenix in C. nasus nasus (commonly known as anchovies), the implementation of measures to limit fishing. Knife in the river from April to May breeding season, the Ministry of Agriculture before asking fishermen fishing license holders Coilia. However, Shi Wei Gang and Qin'an small boat with windows all hold the same view: according to the present situation, Jiang knife should be ban, not limit fishing. "In order to maintain this population, Jiang knife fresh taste no matter how beautiful, human being have to give up this tasty." Shi Wei Gang on the grounds that human beings in order to sustainable use of river knives, they must find a "turning point." "If the state does not catch the Yangtze River, there are 500 tons of knives, this year, 250 tons of human fishing off the next year, it can recover through natural reproduction to 500 tons, 250 tons of it to keep the river is 'turning point'. "Human in the 'turning point' over use of resources is sustainable use. In the 'turning point' under the use of resources, is destructive use. Destructive use of the results, will allow the species to extinction. This is a scientific law. "Shi said. The face of the views of scholars, Changshu City, fisheries station made a grass-roots workers, asked: "thousands of years did not catch light, it will be able to light-harvesting two or three decades?" He believes that the main cause of river knife to reduce water pollution in the Yangtze River . "How can the economic developed cities, a few can be found in the river fish? Why did Jiang knife quickly extinguished, and asked those industrial belt along the Yangtze River to the taxpayer." The fishery officers said. Recently, the CPPCC National Committee of Population, Resources and Environment Committee and the China Development Research Institute jointly organized the "Protection of the Yangtze River Tour" Expedition to participate in the China Development Research Institute study Qi Zhang, Executive Dean told the media afterwards, Chongqing area is a small coke, refining and ore enterprises, to Hubei, Jiangxi, Anhui, Jiangsu, look both sides, many large iron and steel, shipbuilding, shipbreaking and other heavy polluting enterprises along the clouds. Even worse, these companies are almost all of the sewage treatment plant "deaf ears", a considerable part of untreated sewage directly discharged into the Yangtze River. According to "China Environment Statistical Yearbook (2003)" Statistics, when the Yangtze River is 163.9 billion tons of total waste water, of which 72.5 billion tons of industrial waste water emissions, waste water discharge volume of 91.4 billion tons. Shi Wei Gang another post, under the Ministry of Agriculture fisheries resources of the Yangtze River station owners. For example, he said, the spring of 1999, Zhenjiang Yangtze River, the original monitoring points established Coilia large enterprises due to a nearby sewage impact Coilia no trace, but this time around Nanjing, Jiangyin Coilia production has been stable. "Even if the concentration of pollutants one o'clock Bu Zhiyu home Coilia kill, its long-term chronic toxicity can also affect the reproductive system of C. nasus, causing the reproductive system abnormalities, fertility decline. In addition the presence of contaminants in water can also affect the water in the food organisms the rich, and thus affect the fatness of C. nasus, C. nasus commercial value to decline. "Shi Wei Gang said. Students also believe that fishermen Jiang Chen Chu knife is reduced after 1973, "then, Riverbanks plant built up, sewage, wastewater discharge came." Son of Chen Liang added that he often some big factories in the vicinity of river water that has been choked to death in the carp, sturgeon and bream. Chen Chu a lifetime of fishing life, three meals a day are all on board, drinking water is also taken directly from the Yangtze River. His most immediate feeling is that "there are shares of the former sweet river, the river now, not delicious." Who will protect the spawning river knife So far, not along the sides to Fangdui Jiang knife which spawning survey project, no one knows where the new spawning grounds, and no one knows whether these places are being or a variety of river sand mining boat damaged by the works. Knife sharp drop in the number of the main river, Shanghai Fisheries University teachers have their own views what --- Knife River has been extensive damage to the spawning grounds. "But so far, along the two sides not to Fangdui Jiang knife which spawning survey project, no one knows where the new spawning grounds, and no one knows whether these areas of sand mining boat or being damaged by the works of various river . "What is said," If we do not protect these small number of spawning grounds, is likely to further activities of human _set_tlement in the Yangtze River saury drowned. " If you are a fish "Expanding its living space in humans, when to think more like a fish and other animals. Otherwise, punishment will come that day." April 27 afternoon, a professor of Shanghai Fisheries University, Tang Fish Joe explained what he wanted to listen to reporters after the said laughingly: "You can change the angle, from the perspective of a fish." "If you are a saury, you may become Many of the past 20 years, human actions are angry. think about it, you and your companions from the sea to swim to the river, with feelings of happiness and freedom, because the Yangtze River is your home. "You and upstream partner, you feel like the kind of water. But you find that the river flow slows down, because a lot of river upstream of the dam was built. Then you find the taste of the river in some places bad. "Yeah you travel tour, to find their place of birth, giving birth to your children. But one gate blocked your way, or piece has a choking smell of tributaries. You also found that not a lot of river bank soil into the cement, and many of the shore without your favorite plants. "Far more than that, you eat it does not happy. Do you like shrimp, small silver fish are pathetic ... ..." Joe Tang said after completing his hypothesis, this is not just a river knife thing, living in the Yangtze River All fish do. "Expanding its living space in humans, when to think more like a fish and other animals. Otherwise, punishment will come that day." Fishing Chen Chu sang to himself: "I do not know 70 birthday, when can not see the Yangtze River in the knife. "son of Chen Liang said:" I have not seen the Yangtze River shad 10 next year, and have long forgotten what he looks like. another 10 years, I will not Jiang will also forget the knife looks like. "

Overview
Yangtze saury, generic long-jaw anchovy, also known as C. nasus. The flat side of its body length, abdominal silver and greasy, so named because of the shape of a knife.

Residents of many cities along the Yangtze River, the Yangtze River known as saury knives, they know, compared to deep-fried and placed in tin cans, sixty-seven yuan for a box of anchovies sold, Jiang Xiao soil knife worth of difference has been --- a hotel in Jiangyin, three knives gather a Jin Jiang, steamed into the disk, price of a million, this was the latest price. Some older ones Jiangsu know, this huge spread to form in the previous 20 years.

Chen Chu raw saury fishing season
Chen Chu of Health admitted that the saury season, both he and his brother to a total of 300 pounds was caught saury, only equivalent to the 20th century, catches of 80 subnet. April 26 morning 7:54, a 30 cm long knife was pulled out of the river, river, the sun shining fish quickly tap water, then, the card online fish floating in the sky, it is hard to head torsional river, body Comparative Study and Integration, a second bent rigid semicircle. This is Chen Chu Changshu Health fishermen caught the first day of the Yangtze River saury, two hours ago, he and his brother Chen Chu root of the drive a diesel-powered fishing boats, fishing Xupu starting from Changshu, near the east into the Su-Tong Bridge section of the Yangtze River. This is the raw 62-year-old Chen Chu river knife, a favorite fishing ground. 7:10, Lufeng Ying Chen Chu by his wife and small son, Chen Liang, a gill net would be thrown into the river between the two ships. This morning, repeated twice in the net drag action, Chen Chu Health brothers got their season in the biggest catch of the saury: A total of 159 Knife River Treaty size 30 kg. But I do not like Chen Chu students saw the process as exciting news, the harvest too late, now is the season river city knife, fishmongers are given the purchase price is less than one-tenth of the peak. A month ago, the Yangtze River will see the fishermen who sail boats sped from the fishmonger, who captured every river in search of a fishing knife, out of a Jin 700-1000 yuan's high, while the prevailing market on Jin Jiang knife was once a price of 2,000 yuan. But by that time, Chen Chu students who can only be waved red dealers. March 15, the saury catch of a lifetime of elderly people scattered the saury quarter of 2005, the first net. Unprecedented high prices on the market, so that he seems to face a maximum bet of gambling, "Slow Boat to twist the throttle, my hands are a little shiver." Chan Chu Chan said. That day, when more than 500 meters long gill nets from the river slowly pulled out, Chen Chu River Health fishing knife to see his career in the first empty net, to the day, he sprinkled a total of 4 network, all Space Network and, saury without a trace. After 8 days, still nothing, 9 days, he appeared on the Internet gill end of 2005 the first river knife, but all that day's harvest, only a mere 2 pounds and 8 two. "This is the year have not been any thing. My feeling is that this year's River Knife half less than last year at least." April 26, Chen Chu raw saury quarter of this year's poor start continues to bear a grudge, his face calmly looked down, under the right index finger unconsciously about paddling SHIP. At this time son, Chen Liang received the thread of her conversation, "my dad a few years of river fishing knife, this had never come across an empty net. You can imagine his heart? A farmer planted a year and in the end crop failure , what would feel? "In fact, when reporters after the Chen Chu of Health on April 26 informed Changshu harvest fishery station, a staff member, the other party could not believe it," there so many? When this fish is the most recent days, but one day catch of 10 pounds a boat has become regarded as a good income. "The fishery officers surprised the grounds, this spring, Shanghai, Jiangsu and Anhui issued a number of urban media saury" missing "exclaimed, Shanghai," Wen Wei Po, "April 1 report: Nan Li Jingui fishermen from fishing from the early February dozens of saury fish have only been 5 days. Chen Chu students admitted on April 26 this year the harvest was his rare good fortune. The saury season, both he and his brother to a total of 300 pounds was caught saury, only the equivalent of the last century, catches of 80 subnet. The Lao Yumin mind, there is a clear production of table knives Jiang: "Before 1973, we are also two boats fishing river knife, but the ship was rowed the boat. Net were one-third length, quality and well, catch a fish, will make a net. But before Tomb Sweeping Festival, one net, to catch at least 200 kg river knife, when up to 600 kilos. "Knife River up to 1973, a master of our village before and after the month during the Ching Ming Jiang jin grabbed a knife, I caught that year to 6,000 pounds. I caught a river through the largest 6 double knife, when the river knife even sub-4 pound fish was enough. "" Since 1973, a small river knife year after year, year after year and thin. the fastest decline since 1995, but there is forty or fifty year subnet pounds, in 1997 only network subnet to two to three pounds of the. "" by the year 2002 before Tomb Sweeping Festival, subnet spread down to only one of the two. That knife for the price of Jiang Meng Wang on the turn, fishing The purchase price on a 1 kg 500. In 2003 and 2004 reduced the number of river knife was not obvious, but the purchase price rose clear and bright fishing boats around 650 per catty. "

Knife River astronomical source
Fishing Town, Jingjiang City, Jiangsu woman farmer's market, two months ago, Knife River in 2005 an important source price. The market many times a "grab fish" storm, some people even fight. April 29 morning, fishing from the dozens of kilometers of Health Chen Chu Jingjiang City in Jiangsu woman fishing town farmers market, each saury fish stores still sell at this time, more than 2 saury price of two in every hundred Yuan Jin above. This seemingly quiet, Jingjiang City, the largest farmers market, two months ago, Knife River in 2005 an important source price. "The end of February and early March, I've sold a knife Jiang yuan per jin 1800,1700. Such a good market for a week, 300 higher than last year to block." Stir a hand stall Liu the saury ice body, and some excitement recalls. During that time, every day, many cars parked in the market door sedan. From Shanghai and Nanjing and other places to buy authentic to the owners of the Yangtze River saury, but many of them will be "persuaded to go," because of a serious shortage of river knife, a high price then it is difficult to buy, buy fish also rely on "relationship." That is what the fishermen born Chen Chu chagrin of time space network, obviously, Jiang knife market and fishing boats on the river has a direct cause and effect. The reason why the wealthy patrons gathered fisheries woman farmers market buy "authentic" Jiang knife, the reason for the migratory habits of the Yangtze River on saury. Jingjiang since ancient times, "saury town" reputation. Allegedly, the tide into the furthest point of the Yangtze Estuary just in Jingjiang Newport, Knife River since ancient times, where are gathered together in groups, and, when the migration now, and gradually reduce the salt fish was appropriately contained, in addition to gonadal development began to accelerate, so section of the river here by the middle of the most beautiful river knife taste. Local market sources, Jingjiang City, Jiangsu produced in Newport this year is very little actual knife, most sword Jiang from Shanghai and Jiangsu other section of the river come together and shoot the "Jingjiang saury" to Bo high prices. What is more, the Shanghai sea fishing knife and Chaohu Lake and other places fishing knife, into the local river in the "gold plating", posing as river knife. As the name suggests, the sea offshore fishing knife saury not migratory, and the lake knife, a long life in fresh water river in the same knife, the real diners are aware, Knife sea, lake and river knife blade shape similar to, although its taste as good as night and day value has no match. Another stall holders told reporters that Jiang knife just listed this year, the market many times a "grab fish" storm, some people even fight. Some aquatic shop knife river was once the auction scene. It was confirmed that the most expensive pound more than the 2,000 yuan Jiang knife. This spring, river knife worth the high jump ever become a common phenomenon along the Yangtze River. Several local media have reported this: March 15, Nanjing, Jiangsu knife against previous years, the retail price of a gradual decline after the listing of the norm, as amended, weight 150 grams (3 two) beginning from the listing price of 2,400 yuan / kg soared to 3,000 yuan / kg, _set_ting a new high of nearly five years. March, Suzhou River on the market call for knife 4,000 yuan a kilogram of the price. March, the Shanghai market, Jiang knife break 4,000 yuan a kilogram. April 12, Tongling, Anhui Province on the market, "Yangtze River saury" has been "full listing", and 3,600 yuan out of the astronomical price of a kilogram. Although this river knives are experts suspected frozen Chenhuo next year. "Clear and bright before the fish bones as soft as cotton, fish bone after Ching Ming as hard as iron," the appetite of diners River Knife market is an important determinant. Since ancient times, Jiang knife, shad, blowfish and that "the Yangtze River Sam Sun," because the saury to market first, so Sam Sun of the first column, but this fine barbed fish very much, so hard and soft fish bones before and after the change during the Ching Ming , greatly affect the taste. A passion for diners to eat in Nanjing river knife description: "before Ching Ming Jiang knife, meat tender and smooth, delicious non-party matter, Fishbone mouth. That people just want to close their eyes feel fine chemicals, intoxicated. "There are also accounts of Li Yu Qing gourmet:" Fresh fish, carp and sturgeon are tired, the anchovy is more to chew more willing to release almost can not feed their families. "In recent years, pre-Qingming Yangtze River knife into the city's most fashionable One of the gifts, but most reflect its value, or restaurant meals in a steamed Stanford saury. And separated by a river, Jingjiang City, Jiangyin City, the economic strength among the nation's counties and cities in the forefront of the hundred, here a few museum staff said Jiang, Qingming ago, the museum a steamed River Knife price was as high as 6,000 yuan or more. He said a knife generally Sheng Jiang 3, weighing about 1 kg or so. Information, before the Ching Ming Jiang knife fish, hectogram fat 16.8 g, protein 14 grams, 1.1 grams of phosphorus. The beauty of steamed River is the knife, into the tray is not to the scales, high temperatures, the fish drops into the oil beads microlepis, even more delicious. Industry sources said that in the spring of Jiangyin, a high-end restaurant prices for every dish steamed river knife in the million or more. Not only that, Jiangyin, a few museum boss Jiang, Qingming, he knives every day a source of worry for the river, because the competition to concentrate on each hotel in the fish body: "Which hotel today authentic river knife, Which business is like, because it means that rich patrons will come. "Media reports indicate that similar competition was also the case in Shanghai, Nanjing, Suzhou, Wuxi, Changzhou and Nantong.

The cost of a fish catch
Health Chen Chu Chen Chu brothers are caught with 300 kilos of root saury 2 million yuan were sold, but the two boats diesel consumption value of 4,000 yuan. This points down, only points for every family about 8,000 yuan. Which is 8,000 yuan, Chen Chu to students for half of all life, a family of three. April 26 noon, in the Soviet Union often fishing 19037 fishing boat deck, Chen Chu of Health pointed to the river is divided into three groups of medium and small knife to his day's earnings reporters estimate. 2 more than the two major knife 56, both of 14 pounds 2, 60 yuan per catty; a two and a half to 2 ounces of the 65 river knife, about 10 kg, 15 yuan per catty; a two and a half below the 38 small river knife , about 4 half kilogram, 5 yuan per catty. Quarter of 2005, one of the biggest catch of saury, Chu Chen brothers brought about thousands of students of revenue, from the amount of speaking, which sell for less than 30 pounds of fish in late March and harvested 2 pounds 8 for his first two rivers knife income. Knife river was 700 yuan per catty, subnet sold 1,400 yuan. This spring, students Chen Chu Chen Chu root of the brothers are caught with a total of 300 kilograms of saury sold 2 million yuan, but the two boats diesel consumption value of 4,000 yuan. This points down, only points for every family about 8,000 yuan. Which is 8,000 yuan, Chen Chu to students for half of all life, a family of three. Six months later, their brothers will once again sail into the river, Feng anchovy fishing. Now, Chen Chu students face another problem is that the cost of shipping and the network can not be recovered. "I regret buying this the net." Chen pointed to the white fiber silk goes into the gill nets, this is his life in the most expensive to buy fishing nets, worth 6,000 yuan. A fisherman on his way, having this special saury fishing nets, have been just as good soldiers want to have a gun as natural and necessary. 4 years ago to 30-year-old son to get married Chen Liang, Chen Chu, 59, a handful of students decided to fight, then spend 4 million on the purchase of a used small diesel engine steel fishing boat, while the acquisition of this expensive teeth The gill nets. "I caught a lifetime river knives, knives Jiang know little of these years, year after year, but I never expected decline Jiang knife so fast." 4 years ago, Chen Chu Health Net purchase of the ship, a seasonal river knife income, at least twice now. This time he heard from another reporter mouth bad news, since the spring of 2002, the Yangtze River fishing ban has been implemented, thousands of copies each year fishing concession card river knife, much in the first two years fishermen favor. This year, there is a considerable part of the fisheries sector to remain in the hands of staff. In Changshu, 29 to 14 cards only. Chen Liang with a fisherman son inherited his father had intended, but now he changed his mind: River knives have been a few years can be arrested, while the number of C. mystus also decreased year by year, fishing has been unprofitable, must seize the time "into the plant." "Young people no one important fishing village, the fish will starve to death." Liang-like response to a reporter, he pointed to the river shore waving plants, the river's sand boat.

Knife River is far more than missing
Chen Chu of Health in charge of management of fishing fishery station in Changshu City, Chang Chin-hua, deputy chief also revealed disturbing figures: In 1973, the Suzhou River Knife middle section of the river about 400 tons, only to produce 70 tons of Changshu, 2004, Changshu only outputs of about 2 tons of river knife. "But the 20th century, late 80s, early 90s, Hunan and Hubei section of the river essentially no migration of the saury to the. Two or three years, in Jiangxi, is gone. About 1996, Anhui section of the river has shaped Fishing was not a hearing. Another fish is comparable with the column "San Xian Yangtze River" of the Yangtze River shad, the fish in the Yangtze River has been missing for up to five or six years. The process is also in steep decline in recent decades, migratory routes shortened, and then disappear. "Poor fish" are of no return Qin'an small boat with windows that, if not the talismanic --- Qingming Jiang knife after "bone hard as iron", which is no longer a delicacy, it may already extinct. "From the perspective of a fish, migratory river knife is very tragic. You think about it, spring, river knives were struggling to swim into the Yangtze River, is to love, spawning, breeding their offspring. But human beings, but in Zhang Da thousand river network, they had time to catch them before breeding! "71-year-old associate professor of Nanjing University, said Qinan small boat with windows. 70,80 at the turn of the 20th century, Qin'an small boat with windows in the South Life Sciences Professor Yuan Chuanmi led and participated in the earlier study Jiang knife. "This fish is very hot-tempered character, OCS arrest, unlike other fish, as quiet, but not willing to struggling, oxygen consumption, a few minutes died. We do not know that the poor fish in the end death is hypoxia, or scared to death, in short, Yes that is wasted step. "fishers of Health Chen Chu also told reporters that in addition to the regular fishing boat, the river there are many irregularities in the small trawl nets Shenshui Wang, and Plug nets, some network mesh is very small, the size of the aquatic fish pass to kill, and even eggs can be tangled. Qin'an small boat with windows that, if not the talismanic --- Qingming Jiang knife after "bone hard as iron", which is no longer a delicacy, it may already extinct. This is the nature river knife left a way out. At this time, a chance to swim to the river knife completed spawning breeding. However, when the eggs into a river fish knife, return to the way the sea is also extremely difficult. Another scholar in 1989, specifically mentioned that field eel frenzy. At the time, the skyrocketing price of domestic eels, artificial eel be huge profits, while the artificial propagation of eels can not solve. For a time, the Yangtze River net, plug network clouds, crazy catch eel. "Eel net mesh, small enough to be tangled up in the granular particles slightly larger eggs. As eel fishing season and return to the sea river knife seedlings some time overlap, for a time, numerous river knife was hanging dead in eel seedling online , was eventually thrown away as waste. "

Base personnel asked fishery
The face of scholars should ban knives river views, Changshu City, fisheries station made a grass-roots workers to ask: "did not catch light for thousands of years, it will be able to light-harvesting two or three decades?" He believes that reduced river knife main cause of water pollution in the Yangtze River. "It now appears that we have over 20 years ago did not play a role in the appeal, Jiang knife today, is said to be in our big mouth. I am sad because it was entirely avoidable." Qin'an small boat with windows that, in the 20th Century the late 70s, early 80s, South teacher of Life Sciences, 5 river knife five or six years, then felt a small river year after year the number of knives. Therefore, they share many scholars in a variety of domestic limited fishing at the river called knife Animals have talked to the State. The reality is, the relevant state departments have taken note of the Yangtze fish resources. In 2002, the introduction of the spring cut the Yangtze River, the Yangtze River and the phoenix in C. nasus nasus (commonly known as anchovies), the implementation of measures to limit fishing. Knife in the river from April to May breeding season, the Ministry of Agriculture before asking fishermen fishing license holders Coilia. However, Shi Wei Gang and Qin'an small boat with windows all hold the same view: according to the present situation, Jiang knife should be ban, not limit fishing. "In order to maintain this population, Jiang knife fresh taste no matter how beautiful, human being have to give up this tasty." Shi Wei Gang on the grounds that human beings in order to sustainable use of river knives, they must find a "turning point." "If the state does not catch, there are 500 tons of Yangtze River knives, this year, 250 tons of human fishing off next year, it can recover through natural reproduction to 500 tons, 250 tons to maintain that the river is 'turning point'. "Human in the 'turning point' over use of resources is sustainable use. In the 'turning point' under the use of resources, is destructive use. Destructive use of the results, will allow the species to extinction. This is a scientific law. "Shi said. The face of the views of scholars, Changshu City, fisheries station made a grass-roots workers, asked: "thousands of years did not catch light, it will be able to light-harvesting two or three decades?" He believes that the main cause of river knife to reduce water pollution in the Yangtze River . "How can the economic developed cities, a few can be found in the river fish? Why did Jiang knife quickly extinguished, and asked those industrial belt along the Yangtze River to the taxpayer." The fishery officers said. Recently, the CPPCC National Committee of Population, Resources and Environment Committee and the China Development Research Institute jointly organized the "Protection of the Yangtze River Tour" Expedition to participate in the China Development Research Institute study Qi Zhang, Executive Dean told the media afterwards, Chongqing area is a small coke, refining and ore enterprises, to Hubei, Jiangxi, Anhui, Jiangsu, look both sides, many large iron and steel, shipbuilding, shipbreaking and other heavy polluting enterprises along the clouds. Even worse, these companies are almost all of the sewage treatment plant "deaf ears", a considerable part of untreated sewage directly discharged into the Yangtze River. According to "China Environment Statistical Yearbook (2003)" Statistics, when the Yangtze River is 163.9 billion tons of total waste water, of which 72.5 billion tons of industrial waste water emissions, waste water discharge volume of 91.4 billion tons. Shi Wei Gang another post, under the Ministry of Agriculture fisheries resources of the Yangtze River station owners. For example, he said, the spring of 1999, Zhenjiang Yangtze River, the original monitoring points established Coilia large enterprises due to a nearby sewage impact Coilia no trace, but this time around Nanjing, Jiangyin Coilia production has been stable. "Even if the concentration of pollutants _set_ Coilia moment Buzhi Yu kill, its long-term chronic toxicity can also affect the reproductive system of C. nasus, causing the reproductive system abnormalities, fertility decline. In addition the presence of contaminants in water can also affect the water in the food organisms the rich, and thus affect the fatness of C. nasus, C. nasus commercial value to decline. "Shi Wei Gang said. Students also believe that fishermen Jiang Chen Chu knife is reduced after 1973, "then, Riverbanks plant built up, sewage, wastewater discharge came." Son of Chen Liang added that he often some big factories in the vicinity of river water that has been choked to death in the carp, sturgeon and bream. Chen Chu a lifetime of fishing life, three meals a day are all on board, drinking water is also taken directly from the Yangtze River. His most immediate feeling is that "there are shares of the former sweet river, the river now, not delicious."

Who will protect the spawning river knife
So far, not along the sides to Fangdui Jiang knife which spawning survey project, no one knows where the new spawning grounds, and no one knows whether these places are being or a variety of river sand mining boat damaged by the works. Knife sharp drop in the number of the main river, Shanghai Fisheries University teachers have their own views what --- Knife River has been extensive damage to the spawning grounds. "But so far, along the two sides not to Fangdui Jiang knife which spawning survey project, no one knows where the new spawning grounds, and no one knows whether these areas of sand mining boat or being damaged by the works of various river . "What is said," If we do not protect these small number of spawning grounds, is likely to further activities of human _set_tlement in the Yangtze River saury drowned. "

If you are a fish
"Expanding its living space in humans, when to think more like a fish and other animals. Otherwise, punishment will come that day." April 27 afternoon, a professor of Shanghai Fisheries University, Tang Fish Joe explained what he wanted to listen to reporters after the said laughingly: "You can change the angle, from the perspective of a fish." "If you are a saury, you may become Many of the past 20 years, human actions are angry. think about it, you and your companions from the sea to swim to the river, with feelings of happiness and freedom, because the Yangtze River is your home. "You and upstream partner, you feel like the kind of water. But you find that the river flow slows down, because a lot of river upstream of the dam was built. Then you find the taste of the river in some places bad. "Yeah you travel tour, to find their place of birth, giving birth to your children. But one gate blocked your way, or piece has a choking smell of tributaries. You also found that not a lot of river bank soil into the cement, and many of the shore without your favorite plants. "Far more than that, you eat it does not happy. Do you like shrimp, small silver fish are pathetic ... ..." Joe Tang said after completing his hypothesis, this is not just a river knife thing, living in the Yangtze River All fish do. "Expanding its living space in humans, when to think more like a fish and other animals. Otherwise, punishment will come that day." Fishing Chen Chu sang to himself: "I do not know 70 birthday, when can not see the Yangtze River in the knife. "son of Chen Liang said:" I have not seen the Yangtze River shad 10 next year, and have long forgotten what he looks like. another 10 years, I will not Jiang will also forget the knife looks like. "
