The Yangtze River has shown a marked ecological recovery after a 2021 fishing ban and protection campaign. Fish biomass in the river has roughly tripled in recent years following decades of pollution and overfishing that contributed to species loss such as the baiji dolphin. Observers say the rebound highlights the effectiveness of conservation measures and could boost China's environmental credentials internationally.
Yangtze River Biomass Triples After 2021 Fishing Ban, Signaling Major Ecological Recovery
Yangtze River experiences major recovery after 2021 fishing ban
A sweeping fishing ban and protection campaign launched in 2021 have helped trigger a dramatic rebound in the Yangtze River's ecosystem. Once a sink for industrial waste, sewage and rubbish, and long ravaged by overfishing, the 6,300-kilometre (3,900-mile) Yangtze — Asia's longest river — has seen the total weight of fish in its waters roughly triple in recent years after decades of decline.
What Changed
Authorities introduced a broad protection campaign in 2021 that included a moratorium on commercial fishing in key stretches of the river. Early monitoring reports indicate a substantial recovery in fish biomass, suggesting that reduced fishing pressure and heightened conservation measures are producing tangible benefits for aquatic life.
Why It Matters
Decades of pollution and unsustainable fishing had driven several native species to the brink or to extinction — most famously the near‑blind baiji dolphin. The rebound in fish biomass is a hopeful sign that concerted policy action can reverse long-term environmental damage. Observers, including The Economist, have noted the recovery may also offer China an opportunity to bolster its international image on biodiversity protection.
Key point: While the biomass rebound is encouraging, long-term recovery of the Yangtze's full biodiversity will require continued pollution control, habitat restoration and enforcement of conservation measures.
