Mass of dead fish found in N China city

Masses of dead fish float in the Haihe River in North China's Tianjin municipality, July 21, 2011. A one-kilometer trail of tens of thousands of dead stickleback fish was discovered in the river. Local environmental monitoring workers said an increase in contaminants in the river water due to recent high rainfall choked the fish, which can live in both fresh and salt water environments.
