Over 30 tons of dead fish appear in China lake

A vast number of dead sea fish mysteriously appeared in a freshwater lake in the Chinese city of Haikou. The video shows a large part of the lake covered by dead fish. Sanitation workers are seen busy recovering the dead fish and have reportedly collected more than 30 tons. The fish are suspected to have come from somewhere in the Pacific Ocean, as these species are not native to the area in which they were found.
