A video clip from a CCTV news program shows that about 100,000 kilograms of fish died from the polluted water at a fish farm in Caidian District, Wuhan, Central China's Hubei Province, June 5, 2007. CCTV said that polluted water from upriver was discharged into the fish farm under the cover of heavy rain, causing the outbreak of blue-green algae and leaving the fish dead for reduced oxygen in water. Xia Xiaofang, one of the four owners of the fish farm, told CCTV that all fish in his farm died and the largest one weighed about 20 kilograms.
