Scientists study fish in China's Chishui River to restore Yangtze ecosystem, aiding rare species recovery.
Chinese scientists are using the Chishui River, a tributary of the Yangtze River, to study fish ecology and restore the Yangtze's ecosystem.
Since the 1990s, researchers have monitored over 160 fish species, including rare ones.
A "10-year fishing ban" and the removal of over 320 small dams have helped fish populations recover.
These efforts aim to restore endangered species like the Yangtze sturgeon and finless porpoise.
