Question 2: What kinds of fish are there in the Yangtze River? The Yangtze River and its tributaries and lakes, including Dongting Lake, Poyang Lake and Taihu Lake, are rich in fish. Fishery has been widely developed and is the main livelihood of many people in this area. As many as 500 species of fish can be found in rivers in China, most of which inhabit the Yangtze River and its tributaries. About 30 species of river animals are of economic significance, especially carp, European eel, perch, horse clam (a large burrowing clam) and lamprey; The most economically valuable are white and black Amur fish, flounder and spotted flounder. Sturgeon is also important; The canyon is a fertile spawning area. Further downstream, you can find a large number of fish eggs, which are collected and scattered all over the country for artificial reproduction.
Question 3: What fish are there in the Yangtze River? The Yangtze River also has unique swordfish.
Question 4: Are there any valuable fish to eat in the Yangtze River? The greedy cat knows that there are saury and shad, but it's a pity that it can't afford it. They haven't eaten, but they can only afford kittens and fish. And Chinese sturgeon, which is not delicious.
Question 5: Seek fishing experience in the Yangtze River. What fish is easy to catch? This paper introduces the skills of river fishing. I also fish in the tributaries of the Yangtze River all the year round. I feel that the fishing method in the Yangtze River is really different from other fishing methods. Let's have a look.
Fishing in such a large flowing water of the Yangtze River is very different from pond fishing in both the application of fishing skills and the choice of fishing tackle. For example, the sensitive long tail wind drift used in still water fishing is useless in running water fishing; In addition, the river has ups and downs, sometimes turbid and sometimes clear, the topography of the river bank and river bottom is complex, and there are few fish in the river. It may not be easy to catch fish quickly before gaining experience in river fishing. So in general, river fishing is much more difficult than pond fishing.
Although river fishing is difficult, everything has its own rules, and river fishing is no exception. In the choice of fishing position, where does the surging river get off the hook? The experience of fishing in the river tells us that according to the general principle, we should choose the inside of the bend or the place with aquatic plants; The estuary of a river is usually a place where fish are concentrated; There are also places to stop boats and row rafts, which create shadows underwater, and fish have the habit of hiding in the dark; Leftovers left by people are also the goal pursued by fish and can be used as fishing spots. Of course, the choice of fishing spots is closely related to what fish to catch.
In general, if you fish, you can use the method of "fishing in motion and fishing in silence", such as fishing for small tributaries, fishing for the swirling flow of large streams, and finding a place with stable water potential to get off the hook. However, some fierce fish, such as yellow diamond, like to swim in the mainstream of rivers to catch other fish. If you catch these fish, you should unhook them in the dense rapids.
In rivers, there are all kinds of fish, and all kinds of fish have different habits, such as fish migration and spawning, and requirements for water temperature. Only by knowing their habits can they catch fish. These understandings can be practiced by yourself through investigation and inquiry, which is the most important preparation for river fishing.
Earthworms, chicken intestines, duck intestines and other meat baits are usually used to catch running water, and hard pasta that is not easy to be washed can also be used in places where running water is not urgent. Generally speaking, you don't have to make a nest to catch running water. You can spread some bait that is not easy to be washed away in the river section with stable water potential and the backwater with slow water flow.
The configuration of fishing tackle should be selected according to what fish to catch. Such as fishing small fish on the shore and throwing white bars. You can use a small pole; If you want to catch bigger fish, you'd better use a sea pole. You should have a better wheel. The fishing line can be a solid line with a thickness of 0.45~0.5 mm, and the traction device should not be screwed too tightly, so the big fish can pay off the line automatically when they want to. These devices have the conditions to catch big fish. The fish in the river are wild, which has much greater influence than the fish in the pond.
In the hook group, long brain thread should be used to string hooks, each string can be 4 hooks. Too many hooks are inconvenient. The length of brain silk should be more than 20 cm. After the brain thread is filled with bait, the bait can "live" in the water under the impact of running water, and live food is more attractive to fish. When tying the brain thread, increase the hook distance, and don't hang the hook at the lower hook joint, which can reduce mutual hanging.
It may take a lot of hardships to start river fishing, sometimes even several times, but nothing is achieved, and there may also be cases of hanging the bottom, breaking the hook and destroying the pole. Therefore, river fishing has never been as calm as pool fishing. The most attractive thing about fishing in Jiang Ke is its adventure, hardship and more unknowns, which are eagerly pursued by many fishermen. Friend, I hope you can raise your fishing rod, challenge the Yangtze River and get a new feeling of fishing.
Question 6: What kind of fish is caught in the Yangtze River? The Yangtze River basin is an important habitat and breeding ground for a variety of rare and endangered aquatic wild animals in China, including baiji, Chinese sturgeon, sturgeon, finless porpoise, giant salamander and mullet, among which baiji, sturgeon, Danhu and mullet are endemic to the Yangtze River and have special scientific reference value in ecological evolution, military bionics and archaeological research. With the rapid economic and social development and increasing population in the Yangtze River basin, the aquatic biological resources and ecological environment in the Yangtze River are facing many threats, the aquatic biological resources are seriously declining, and the aquatic ecology is deteriorating and showing a trend of desertification. There are 350 species of fish in the whole Yangtze River system, including the attached lakes, among which 324 species are pure freshwater fish, which greatly exceeds the number of freshwater fish in other rivers in China (there are 239 species of freshwater fish in the Pearl River and only 150 species in the Yellow River). Among the fish in the Yangtze River, 10 species are migratory fish passing through the estuary, such as eels and Songjiang perch, Chinese sturgeon and shad. In addition, there are 16 species mainly living in the salty fresh water in the estuary, but they are often found in the downstream fresh water, such as herring, rope and sea bass. As for the marine fish occasionally seen in the estuary, it can't be counted as fish in the Yangtze River.
Among the fish in the Yangtze River, cypriniformes account for the vast majority, with 248 species, accounting for 70.8% of the total fish in the Yangtze River. Followed by Siluriformes, with 37 species, accounting for 10.7%. Cyprinidae fishes in the Yangtze River belong to 4 families. There are only 1 species in myxocyprinidae, 50 species in loach, 18 1 species in CYPRINIDAE and 16 species in LEPIDOPTERA. Cyprinidae is not only the largest family of fishes in the Yangtze River, accounting for 5 1.7% of the total, but also the main economic fishes in the Yangtze River, such as carp, crucian carp, herring, grass carp, silver carp, bighead carp, bream bream and bream. At the same time, CYPRINIDAE 1 1 subfamily are all distributed in the Yangtze River. In particular, there are as many as 24 species of Schizothorax subfamily adapted to the plateau environment in the Yangtze River system, while in other rivers originating from the Qinghai-Tibet Plateau, only a few species of Schizothorax subfamily are usually distributed.
Question 7: What is the biggest fish in the Yangtze River? The Yangtze sturgeon is the king of freshwater fish. It can be called king, because it has grown up, and some of them are over 100 years old.
There are three kinds of Yangtze sturgeon: Yangtze sturgeon, Chinese sturgeon and paddlefish. Among them, Chinese sturgeon and Chinese sturgeon are the largest, with a body length of 7 meters and a weight of several hundred grams, which can be described as the real kings of freshwater fish.
Sturgeon, like salmon, was born in the inland Yangtze River, but grew up in the sea. Breeding came, and groups of sturgeons swam back to the Yangtze River from the East Haikou and went upstream to breed in Jinsha River in Yibin, Sichuan. After the fish is born, it flows into the sea with the river, grows in the sea to about 10 years old, and then returns to its birthplace to reproduce. It has been going on.
Sturgeon is fierce and lives by preying on other fish.
Question 8: How many kinds of fish are there in the Yangtze River? The rare fish in the Yangtze River are mainly Chinese sturgeon and mullet. According to experts, due to environmental pollution and uncontrolled killing, the number of fish in the Yangtze River is decreasing sharply. The number of fish surviving in Jiangsu section of the Yangtze River decreased sharply from 1 and 6 1 in 1970s and 1980s to about 1. Yangtze shad, once ready to catch, has disappeared since 1990s. Zhou Kaiya, a professor at Nanjing Normal University and a member of the Scientific Committee of Endangered Aquatic Wild Animal and Plant Species of the Ministry of Agriculture, said sadly that it takes at least 2 million years for the earth to create a species, while it only takes decades or even years for humans to destroy a species. More than 50 kinds of fish have disappeared in just twenty or thirty years. Shouldn't this be thoughtful?
The decrease of fish in the Yangtze River is not only manifested in the variety, but also in the quantity. According to the monitoring data of relevant departments, the fry output of the four major economic fish in the Yangtze River-black carp, grass carp, silver carp and bighead carp-dropped from 30 billion in the highest year to 200 million. The natural fishing output in the Yangtze River basin has also dropped from 427,000 tons in 1954 to about 654.38+10,000 tons at present.
What is even more frightening is that the killing of fish in the Yangtze River has completely entered a vicious circle. The fewer times of arrest, the greater the intensity of arrest and the more means of arrest; The fewer fish species, the higher their economic "value" and the more serious the phenomenon of overfishing and gluttony. In recent years, all kinds of fish houses, fresh seafood houses and restaurants around the Yangtze River, as well as all kinds of fishing tools erected on the Yangtze River, can prove that human beings are carrying out a big encirclement and suppression of Yangtze River fish.
I can't judge how long the fish in the Yangtze River can persist under this siege, but one thing is certain. If it is left unchecked, the day of "keeping the Yangtze River without water to drink and leaning on the Yangtze River without fish to eat" is not far away.
Although, the local * * * also saw the fact that the fish in the Yangtze River are rapidly decreasing, and realized the importance of protecting the fish in the Yangtze River, they also chose a certain time to implement fishing bans every year. But realistically speaking, the so-called fishing ban implemented by local governments on both sides of the Yangtze River has little effect and the effect is not good, and there is no way to protect fish from growing for several months. Once the fishing season is over, killing fish is even crazier. What's more, the fishing ban in some places is just a formality, and there is no real fishing ban.
Academician Cao Wenxuan put forward that the whole Yangtze River basin should be closed to fishing for 10 years, which is not only a good suggestion, but also a suggestion that needs enough courage and courage. Because this proposal will not only be opposed by fishermen, but also by local governments.
A ten-year ban on fishing means that fishermen on both sides of the Yangtze River have no employment and no source of income for ten years. 10 fishing ban means that local governments must solve the livelihood and employment problems of fishermen within this decade.
However, if we can give the Yangtze River ten years to recuperate, and if we can make the fish in the Yangtze River grow steadily for ten years, what will the fish in the Yangtze River look like in ten years? Will the natural catch be so small? Will the variety of fish decrease so quickly? If ten years is really too long, then five or three years, during which time there will be a real fishing ban. So, can the fish scenery in the Yangtze River be greatly improved?
The question now is, if this proposal is really adopted, can the local people play the piano with ten fingers, grasp the ban on fishing on the one hand and the arrangement of fishermen's life on the other?
The ban on fishing in the Yangtze River is indeed a subject that must be taken seriously, studied and explored seriously. I hope this topic will not stay on paper forever, but will be put into action.
Question 9: What is the biggest fish growing in the Yangtze River? Chinese sturgeon
Name: Acipenser sinensis
Origin: China
Commonly known as: sturgeon, sturgeon, sturgeon, sturgeon.
Latin scientific name: ACIPENSER sinensis
English name: Chinese sturgeon
brief introduction
Chinese sturgeon (Aclpenser Sinensis Grdy) is a large-scale anadromous fish, which is an ancient and rare fish unique to China. One of the most primitive fish in the world. Known as "the giant panda in the water" and "the fish king of the Yangtze River". As early as 1 0,000 BC, the Chinese sturgeon was called the king of tuna.
Chinese sturgeon, also known as mandarin fish, is a national first-class protected animal. This is a kind of chondroscleroderma fish, with a long spindle-shaped body, a plow-shaped snout, a broad bottom and a slightly upturned snout. Mouth in a row, with short whiskers in front. The eyes are very small, and there is a crescent-shaped spray hole on both sides of the head behind the eyes, and the whole body is covered with five rows of prismatic bone plates. The caudal fin is curved and the upper leaf is particularly developed. Chinese sturgeon is the highest among 27 species of sturgeon in the world. It is huge and powerful, with a length of over 4m and a weight of over1000kg.
Question 10: How many kinds of fish are there in the Yangtze River, Chinese sturgeon and baiji?
1。 Puffer puffer fish is the most expensive fish, and the freshness is the first among fish. This is good soup, steamed and stewed. It is said that its soup is white and has a very strong flavor. At present, there is artificial culture in Nantong, Jiangsu Province, weighing about 120- 150/ tail, and the processing fee is 120 yuan. Small ones are cheap and can only be made into soup. All of the above can be eaten in Nantong. There are few wild puffer fish now, and I don't know where to eat.
2。 Both shad and swordfish are included in the Garden Food List, and there are two cooking methods: steaming with wine; Or stir-fry with clear sauce and fermented grains (that is, wine making), which is estimated to be similar to our dry burning. The shad must be cooked whole, not sliced. Because the scales of shad are rich in fat, and the scales are steamed and diced, which is delicious, so steamed shad must not have scales.
3。 Swordfish also has two methods, one is steaming, the other is adding honey wine and clear sauce, and now it is steaming with soy sauce; One is to scrape fish fillets with a sharp knife, smoke out their spines, and then simmer them with ham soup, chicken soup and bamboo shoot soup. It's absolutely wonderful. Eating saury before Qingming, but not after Qingming, because saury has too many thorns, a dime a dozen. It was soft before Qingming, and even if it can't be completely taken out, it won't get stuck in the throat. After the Qingming Festival, the thorns of saury are like state-owned assets: it is difficult to clean up. Tomb-Sweeping Day ate saury before. It goes without saying that the meat is tender and delicious, but the taste of Israelis seems to be very greasy: as greasy as Jiangtuan, but fresher than Jiangtuan.
4。 T fish migrate in the Yangtze River, Wusongkou and Chongming Island, with strong seasonality. Spring and summer are the fattest. It has two beards in its mouth, commonly known as T mouse. Its skin is elastic and sticky, and braised in brown sauce is the best. Its color is ruddy and shiny. The fish pieces are covered with a thin and even layer of marinade, and the soup is not thick. The fish itself is sticky, so-called self-thickening, and the skin of the fish is plump. T fish should be one of the four kinds of fish, or it may be like catfish upstream.
