The paper published on Dec 23 on the online edition of the international journal Science of The Total Environment shows that the largest freshwater fish in China might have gone extinct between 2005 and 2010.

Wei Qiwei, an author of the paper, said that in September last year, experts from the International Union for Conservation of Nature estimated that this unique and first-class protected fish had been extinct already.
It represents another animal declared extinct in the Yangtze River in recent years. The baiji, or Yangtze River dolphin, a type of freshwater dolphin, and reeves shad were both classified as functionally extinct.
The Chinese paddlefish is one of the world's largest freshwater fish, which can grow up to 7 meters long. It is an endemic species in China under first-level national protection.

The latest discovery of the fish happened in 2003, and scientists helped the fish to return and tried to track it, but a boat accident caused the tracking efforts to fail. Since then, no discovery was reported and no such fish kept in captivity.
没人能想到这可能是人们最后一次发现长江白鲟。失去这一条鱼,也失去了整个物种。
IUCN前述专家称,目前没有包括影像学等在内的任何证据证明白鲟还存在。如果人们再拍到或捕捉到任何一个长江白鲟个体,IUCN将重新考虑调整其物种濒危等级。

▌长江十年禁渔计划
目前,让长江休养生息,保护濒临鱼类迫在眉睫。
近日,农业农村部发布通告,在长江干流和重要支流除水生生物自然保护区和水产种植资源保护区以外的天然水域实施长江十年禁渔计划。

Starting from this year, the fishing ban will be observed in 332 conservation areas in the Yangtze River basin, which will also be expanded to all natural waterways of the river and its major tributaries from no later than Jan 1, 2021.
2020年起,长江流域332个保护区全面禁止生产性捕捞;最迟自2021年1月1日零时起,禁渔范围将扩大至所有长江干流和重要支流天然水域。
在过去几十年快速、粗放的经济发展模式下,长江生物完整性指数已经到了最差的“无鱼”等级。
禁捕是有效缓解长江生物资源衰退和生物多样性下降危机的关键之举。

禁捕后,渔民怎么办?
对此,农业农村部承诺,会统筹协调落实退捕渔民过渡期生活补助、社会保障、职业技能培训等政策。
The 10-year ban is estimated to affect more than 113,000 fishing boats and nearly 280,000 fishermen in 10 provincial regions along the river. The Ministry of Agriculture and Rural Affairs has promised to provide social security services, financial support and vocational trainings for fishermen who have to find new ways of living.
根据测算,长江流域重点水域禁捕共涉及沿江10个省市的合法持证渔船11.3万多艘、渔民近28万人。农业农村部承诺统筹协调落实退捕渔民过渡期生活补助、社会保障、职业技能培训等政策。
