On June 6 – the Ninth National Fish Day – 220,000 fish were released at stations in Kunming, Chongqing, Wuhan, Nanjing and Shanghai. Among the species were Chinese sturgeon, Dianchi Golden Line Fish, Yangtze River sturgeon, mullet, Shatangli fish, and other rare and native fish. It's hoped the release will help to further restore aquatic resources and protect the biodiversity of the Yangtze River Basin.
