Wild Chinese sturgeon on brink of extinction

BEIJING, Sept 15, 2014 (AFP) - The wild Chinese sturgeon is at risk of extinction, state media reported, after none of the rare fish were detected reproducing naturally in the polluted and crowded Yangtze river last year.

One of the world's oldest living species, the wild Chinese sturgeon are thought to have existed for more than 140 million years but have seen their numbers crash as China's economic boom brings with it pollution, dams and boat traffic along the world's third-longest river.
