Thanks to large-scale ecological protection of the Yangtze River, China has effectively maintained rare fish stocks and enabled the world-famous product caviar to be legally produced on a large scale. The footprints of this transformation can be seen in Yidu in central China's Hubei Province. The villages here are home to large factory farming bases and artificial ponds, and raise more than 1 million endangered sturgeons — one of the main fish that produces caviar. According to the data, China produces 60% of the world's caviar. According to Ji Jianyi, general manager of Qingjiang Sturgeon Valley Special Fishery Co., Ltd., every day, more than 10,000 cans of Yidu caviar are shipped to more than 20 countries.
