Recently, CCTV Finance New Media launched a series of interviews titled 'Don't Hurt Me Again: Ten Statements from Wild Animals', bringing you into a wild animal every night to listen to their confessions. This episode invited Dr. Gui Qiwei, Researcher of the Yangtze Aquatic Product Research Institute of the Chinese Academy of Aquatic Product Sciences, to talk about the Yangtze sturgeon.
The Yangtze sturgeon has existed for 150 million years, once alongside the land overlord dinosaur, survived the fourth ice age, known as the king of freshwater fish in the Yangtze River
The Yangtze sturgeon is already extinct
Researcher Gui Qiwei of the Yangtze Aquatic Product Research Institute of the Chinese Academy of Aquatic Product Sciences introduced: The last white sturgeon appeared in the Yangtze River in 2003, and he and a group of experts treated and released the white sturgeon into the Yangtze River, followed by tracking.
Unfortunately, no white sturgeon was found afterwards.
The aquatic biodiversity of the Yangtze River has long been affected by dam construction, water pollution, overfishing, channel dredging, and sand excavation, and the living environment of Yangtze aquatic animals is deteriorating day by day, and rare and unique species resources are declining, and the white sturgeon is already extinct.
Besides the Yangtze sturgeon, Yangtze aquatic animals are also worrying
Data show that 314 species of fish were collected from the Yangtze River in 2017-2018, and 134 species that had a distribution but were not collected accounted for nearly 1/3 of the total number of fish species in the Yangtze River
Chinese sturgeon and Yangtze river dolphin are critically endangered, especially that Chinese sturgeon has not been found to reproduce naturally for three consecutive years
The 'Four Big Fish' – bighead carp, silver carp, bighead carp and grass carp, which are important aquaculture species in the Yangtze River, have declined to less than 10% of the level in the 1960s
Protect Yangtze aquatic animals, implement 10-year fishing ban
To protect fish spawning and breeding of juvenile fish, China implemented a 3-month Yangtze Spring fishing ban system since 2003, and extended it to 4 months in 2015 and expanded its scope. However, practice proves that 4 months of fishing ban cannot meet the needs of resource protection, and fish are caught empty in a very short time after opening fishing, and the trend of resource decline has not been curbed.
Under this background, the state has introduced stricter fishing ban regulations.
In December 2019, the Ministry of Agriculture and Rural Affairs issued a notification announcing that the Yangtze River aquatic biological nature reserves and aquatic germplasm resource protection areas will be completely banned from fishing starting at 0:00 on January 1, 2020; the mainstream of the Yangtze River, important tributaries and interconnected rivers will implement a temporary ban of 10 years starting from 0:00 on January 1, 2021.
This is a warning to humanity!
