Cao Wenxuan, a scientist who initiated the ten-year ban on fishing in the Yangtze River and an academician of the China Academy of Sciences, estimated that after ten years of rest and recuperation, the number of eggs laid by the "four big fish" in the Yangtze River could rise to about 2 billion to 3 billion, reaching the level of 3% in the 196s at most, while the recovery of many endangered species is more difficult.

Dr. Qian Zhengyi, Deputy Secretary-General of the Yangtze River Ecological Protection Foundation, recalled that during his studies at the Institute of Aquatic Sciences of the Chinese Academy of Sciences, he dissected 6 or 7 dead finless porpoises, about half of which had empty stomachs or other hunger symptoms. "They were hungry, and they couldn't find fish to eat in the vast Yangtze River."

With the orderly promotion of the ban on fishing in the Yangtze River in recent years, the images of Yangtze finless porpoises playing in Poyang Lake, Yichang, Zhenjiang, Nanjing and other river sections frequently appeared in hot searches. "The total ban on fishing has reduced the risk of illegal fishing gear hurting finless porpoises, and their food sources have greatly increased. I believe that in the next few years, their population will be restored to some extent. " Qian zhengyi is very confident about this.

Ten-year fishing ban on the Yangtze River

In order to save the aquatic biodiversity of the Yangtze River, on January 1, 221, the main stream of the Yangtze River, large Tongjiang lakes and important tributaries officially began a ten-year comprehensive fishing ban. 111, fishing boats and 231, fishermen retreated ashore, which began the historical turning point of "people returning fish to enter".

The "No.1 Document of the Central Committee" in 221, which was released a few days ago, clearly proposed to strengthen the conservation of aquatic biological resources, promote the capacity building of fishery law enforcement with emphasis on the Yangtze River, ensure the effective implementation of the 1-year fishing ban, and do a good job in ensuring the resettlement of retired fishermen. According to the strategic plan of the CPC Central Committee on the high-quality development of the Yangtze River Economic Belt, the Yangtze River Protection Law, China's first special law on river basin protection, will also be officially implemented from March 1.
