Now "White 只" can only be "searching" on the stamp

In order to promote and protect my country's rare and endangered biological resources, on March 18, 1994, the Ministry of Posts and Telecommunications issued a set of 4 special stamps in the "鲟", with the names of "鳇", "Chinese 鲟", "White 鲟" and "Da Shi". "为", the stamp designer is Li Yinqing. The first "图" pattern depicts a huge catfish floating in the water, headed, tail, and life is full of vitality. The shape of the shape of the shape is naturally stretched, leisurely, and not fun; the third "white" pattern depicts a white pupa with long heads, long kisses, swinging the body, and moving forward, not only one shows a one, which shows not only a one shows one. The lively momentum is full of vitality, and it has the incentives that inspire humans to work hard; the fourth "Da's 鲟" pattern depicts a Da Shi 鲟 鲟 种 种 种, which exactly shows lively and naturalness accurately. Personality is also filled with a moisture spirit of hard work.

Alas, also known as catfish, is one of the earliest vertebrates of contemporary origin. The catfish belongs to the hard bone fish outline, the spokes, and the hard scales of the cartilage. What you usually call catfish refers to fish -shaped destinations. It is one of the most primitive groups in fish. The catfish is extended, generally a shuttle -shaped shape. The horizontal surface of the trunk is nearly pentagon. The kiss is long, the body is 5 lines, or sometimes exposed. No orbital intervals, front gill cover bones and gills. The bone plate on the head may be or not. The upper edge of the caudal fin has 1 lines of spinal scale.

There are 7 kinds of wild catfish in our country. They are distributed in the Shi Shi, Da Shi, and Kuya Island of Shi Shi, Da Shi, and Kuya Island. Da's; naked abdomen distributed in the waters such as Yining and other places in Xinjiang; it is distributed in the Siberian River in the Ejetis River, the Sea of ​​Burento, and the Lake Bostene. So far, my country has introduced more than a dozen varieties such as Russia, European, Small Bodhisattva, and Spoon Kiss as research or artificial breeding.

Wild catfish is a very precious biological resources. In particular, the "white 鲟" in the stamp of "套" is a rare resource that is rare. It is very surprising that the Yangtze River Baiji, known as the "King of Chinese Freshwater Fish", has been officially announced by the World Nature Protection Alliance. On July 21, 2022, the World Nature Conservation Alliance updated the red list of endangered species, showing that the Yangtze -specific species of white maggots have been extinct and the Yangtze River is extinct. The three Asian catfish mentioned this time include the natural population of white ravioli, Yangtze River, and Siberia. The first two are representative aquatic species in the Yangtze River Basin. Bai Yan appeared in the Nanxi River section of the Yangtze River in 2003, while the Yangtze River (Da Shi) was evaluated as a wild extinction because it failed to find the juvenile fish except for the proliferation and release group. There are more than 4,300 aquatic creatures in the Yangtze River Basin, including more than 400 fish, and more than 170 kinds of fish in the Yangtze River. kind. In 2007, the white -fin dolphin was announced in functional extinction. However, on November 14, 2018, the "Red List of Endangered Species of the World Nature Conservation Alliance" was updated and released. It has not been confirmed that the extinction of the white tipper has not been confirmed to maintain the "extremely dangerous" of the original rating.

On December 23, 2019, the international academic journal "Overall Environmental Science" published a research paper from experts from the Yangtze River Aquatic Research Institute of the Chinese Academy of Aquatic Sciences. It is expected that from 2005 to 2010, the Yangtze River Baiji has been extinct. In January 2020, the World Nature Conservation Alliance responded that the official has not yet released and updated the news about the extinction of the Yangtze River. Dr. Wei Wei, chief scientist at the Institute of Faculty of the Institute of Fisheries Sciences of China Aquatic Sciences, pointed out that the extinction of Bai Yan is something that should not happen. This is not an accident, and other Yangtze River aquatic creatures must not repeat the same mistakes.

Since the reform and opening up, my country has achieved great achievements in protecting rare and endangered biological resources. However, "white 鲟 extinction" is a distressed news. "Extinction is easy to regenerate, I hope Fangchi stays." The Yangtze River Baiyan has once again sounded the alarm for us, and the diversity of freshwater creatures around the world is imminent. The work of issuing rare endangered biological stamps must continue to advance. Thank you very much for my old friend Li Yinqing to carefully designed this set of "鲟" special stamps. Fortunately, "Bai Yan" left Qianying on the national business card. If you miss "Bai Yan" in the future, you can view the "Stamp Catalog of the People's Republic of China". Those who like to philatelic should save the stamp of "鲟", especially the "stretching long head, long kiss, swinging the body, and moving forward. As a permanent memory and reference.
