A total of 50,000 artificially propagated acipenser sinensis, Chinese sturgeon, have been born in Yichang, Central China's Hubei province to increase wild stocks of the rare species. Strugeons, found in the Yangtze River, are one of the oldest creatures on the planet and are thought to have lived at the same time as dinosaurs, dating back 140 million years ago. The world's first batch of 20,000 artificially bred Chinese sturgeons was born in Hubei in 2009. [Photo/Xinhua]
