Fisher Zhang Jinping looks at dead fishes in the Minjiang River in Shuikou Township of Gutian County in southeast China's Fujian Province, Sept. 3, 2011. A large amount of cultivated fishes were found dead with unkown reasons in recent days in the Minjiang River's Shuikou Township section, which is the largest aquaculture base in Fujian. The floating dead fishes, decaying in hot weather, have been polluting the river, the main drinking water resource of the province. The cause is still under investigation. [Photo: Xinhua]
