Extinction fears as wild sturgeon eggs not found
Print Edition
THE wild Chinese sturgeon is at risk of extinction after none of the rare fish were found to reproduce naturally in the Yangtze River last year.
One of the oldest species, the wild Chinese sturgeon are thought to have existed for more than 140 million years but have seen their numbers dwindle as China’s economic boom brings with it pollution, dams and boat traffic along the world’s third-longest river.
For the first time since researchers began keeping records 32 years ago, there was no natural reproduction of wild Chinese sturgeon in 2013, according to a report published by the Chinese Academy of Fishery Sciences.
No eggs were found to have been laid by wild sturgeons in an area in central China’s Hubei Province, and no young sturgeons were found swimming along the Yangtze toward the sea in August, the month when they typically do so.
“No natural reproduction means that the sturgeons would not expand its population and without protection, they might risk extinction," said Wei Qiwei, an investigator with the academy.
