Hong Kong (CNN) -- After the thousands of dead pigs, come the tons of poisoned fish.
The Fuhe River is the scene of the latest disturbing example of river pollution in China.
Authorities cleared about 110 tons of dead fish from a 40-kilometer section of the river in the central province of Hubei, the state-run news agency Xinhua reported Wednesday.
Images taken at the scene this week showed thousands of silvery fish carcasses blanketing large expanses of the river and its shore.

The cause of the deaths, provincial environmental officials said, was the discharge of high levels of ammonia into the water by a local chemical plant in Yingcheng, outside the city of Wuhan.
