The Yangtze River was once wild and biodiverse. But rapid economic development since the middle of the 20th century has led to overfishing, and the abundance and diversity of aquatic life has plummeted. In response, the Chinese government implemented in 2021 a 10-year ban on all commercial fishing in the river basin. Xiong et al. examined fish abundance and diversity before and after the ban and found promising signs of initial recovery in biomass, diversity, body condition, and even threatened species.
Although the fishing ban will not be sufficient to completely recover species threatened by a host of other human stressors, evidence suggests that it has contributed to a trajectory toward initial recovery of fish biomass, diversity, growth, migration distance, and abundance of some of the most endangered and emblematic species (e.g., tube fish and the Yangtze finless porpoise) in the Yangtze River. It has been 19 years since the first spring seasonal fishing ban was implemented in 2002 to protect spawning fish. Now, the ban extends to prohibit all fishing activities for a decade (2021 to 2030) and is thus a bold strategy to slow the loss of and ultimately restore freshwater biodiversity in the Yangtze River
