The story of the ugly duckling is beautiful, it tells us that the setbacks in the early stage are not obstacles to your success, as long as you persist, one day you can always jump up, successfully incarnate into a swan, soaring in the blue sky.
The ending of this story is perfect and desirable.
However, in the fish resources of the mainland, there is such a fish that has a very similar experience to the ugly duckling, and when it is born, it looks very ugly. However, as they continue to grow, metamorphose, and cope with the environment in which they grow, they will eventually become extremely beautiful.
And this fish, it is the celebrity of the Yangtze River, the national second-level protected fish species - rouge!
长江名流胭脂鱼！
The beautiful Yangtze River not only cultivates the culture of the mainland for thousands of years, but also cultivates a batch of ordinary and cherished fish.
If you want to talk about the top stream of fish in the Yangtze River, it is a sentence that describes the Yangtze River: "A thousand pounds of wax is like a thousand pounds, and the yellow row is not very large." A simple sentence directly summarizes the top famous fish in the Yangtze River.
The forward wax in the words is the Chinese sturgeon, the wanjin elephant is a description of the extinct white sturgeon, and the yellow row is said to be a beautiful rouge fish!
Rouge:
Scientific name cochineal, also known as fire bream, yellow row, wooden leaf plate, red fish, purple bream, birdfish, blood row and so on. Cochineal is a migratory fish, a large middle and lower class fish, the main food is benthic invertebrates, organic matter in the sediment, algae, plant fragments. The main distribution areas are the Yangtze River and the Fujian Minjiang River!
The cochineal is a metamorphosis fish, the appearance of the recommendation can be divided into many stages, when it first hatches, its body surface is grayish white; In the juvenile stage, the body color is dark brown, and three black stripes will grow on both sides of the body that run through the whole body; Slowly, after several years of growth, when it reaches maturity, the cochineal will completely transform into a bluish-purple and reddish color!
The main reason why the cochineal is called a large fish is that it can indeed grow very large, the adult body length can reach more than 1 meter, and the heaviest weight can grow to more than 30 kg.
穿梭了千年，扎根长江，如今到了濒危的程度！
The history of the cochineal fish is very long, the earliest can be traced back to the Mesozoic Era, and the mainland cochineal fish flowed into the Yangtze River during the Miocene and survived, rooted in the Yangtze River, gradually multiplied, and finally developed its own ethnic group!
But such an ancient species, the current situation is extremely tragic. According to the statistics of relevant experts, in the past 20 years, the number of wild cochineal fish is extremely rare, and the real number is even less than that of the Chinese sturgeon, which is a national first-level protected animal, and the statistics as of 2019 show that the number of wild cochineal fish is only about 100!
Don't look at the Yangtze River rouge we see now, there are many, and even the market has it for sale. However, it was all artificially bred.
In order to continue the race of cochineal fish not to disappear, the mainland actually began to continue to increase in value as early as 2006, and Wuhan released as many as 182,000 cochineal fry in a release operation on November 23, 2021, with individuals in 5 to 10 cm!
Why are rouge so scarce?
In fact, it is not unreasonable that rouge fish are becoming scarce, don't look at the Yangtze River has now entered a ten-year fishing ban period, but as early as before the fishing ban period, the ecological environment of the Yangtze River is indeed not optimistic. A large amount of sewage discharge, dams, indiscriminate fishing phenomenon is obvious, coupled with a lot of passing ships.
These are all factors that lead to the scarcity of cochineals, and in addition, cochineals are migratory fish, and interception leads to the interruption of migratory routes, which directly leads to the destruction of breeding points; Moreover, cochineal has high requirements for water quality, industrial discharge, ship leakage, water pollution and reduces spawning capacity; Also, the growth process of the cochineal is very slow, from hatching to breeding adult fish, it takes up to 7 to 8 years, deliberate fishing, how can it give them room to grow.
It is such a kind of rouge fish, which is known as a "mermaid", but it has developed from a large group to a precious species that can only survive by value-added release today, which is indeed a pity to think.
禁渔十年能否为它们的烦躁带来转机？
In fact, for the protection of the aquatic resources of the Yangtze River, the mainland has long been involved. Many people will say that the reason why the migratory fish in the Yangtze River are rare is that dam interception is the most important.
Having said that, the construction of dams is a national project for the benefit of the country and the people, and we cannot stop social development because of fish. The construction of dams can not only play a role in flood control and drainage, but also use dams to build power stations to provide more output for the mainland's electrical energy.
Also, in order to take into account the survival of fish in the Yangtze River, in fact, at the beginning of the design of the dam, the engineers themselves had their own considerations, and they all believed in the construction of migratory fish channels and bionic breeding grounds.
Therefore, such a design may not get good results in the early stage, but I believe that as long as the near future, fish can adapt to this way. At that time, the results should have a very gratifying ending.
Coupled with the current ten-year ban on fishing in the Yangtze River in the fishery sector, this is fundamentally to protect the fish in the Yangtze River. From the beginning of the fishing ban to the present, in just over two years, the current situation of fish in the Yangtze River has emerged in the thriving Yangtze River.
In the Yangtze River Basin, white dolphins appear in many places to swim in the water, groups of fish swim on the beach of the Yangtze River, the shore shows their faces, and 100,000 Chinese sturgeon stay at the mouth of the Yangtze River in Jiangsu to rest, waiting to adapt to the sea.
Therefore, we also have reason to believe that the ten-year ban on fishing, which is a good policy for the benefit of the country and the people, can also better promote the recovery of fish in the Yangtze River.
summary
随着长江禁渔的不断加强，我们相信，胭脂鱼这一有着“美人鱼”之称的珍惜物种，它们也会毛毛的从新发展，而那仅剩的100尾野生物种，也终将是它们恢复的种子。 After all, we have reason to believe that it can also be like the "ugly duckling", relying on its own persistence, sooner or later it will successfully counterattack.
What do you think about the wild recovery of cochineal?
