Staff members release immature fish into the Yangtze river in Yichang, central China's Hubei Province, March 1, 2016. The Chinese Ministry of Agriculture has activated an annual fishing ban along the Yangtze River, extending it from the usual three months to four months. The ban, which lasts until June 30, covers the spawning season for most of the river's aquatic life. It includes the entire river as well as key tributaries and lakes. The ban also applies to the Huaihe River, which runs almost parallel between the Yangtze River and the Yellow River. (Xinhua/Xiao Yijiu)
