Massive fish kill blamed on mud

OFFICIALS in neighboring Jiangsu Province are investigating the source of pollution that killed tons of fish, while a government spokesman blamed the deaths on mud.

Hundreds of dead silver carp, grass carp and bream were found floating down part of a river rented by Zhao Ronggang in January to breed fish.

The once transparent water was now dark and smelly, with flies buzzing around dead fish on the riverbank, reported the Yangtze Evening Post today.

Zhao, who spent almost 500,000 yuan (US$73,800) in renting and buying young fish, blamed factories in an industrial zone upriver for releasing toxic sewage water.

Zhao claimed to have seen a pipe discharging dark red water into the river which stretched in Jincheng Township, Jintan County.

However, a spokesman surnamed Chen with the township government explained the dark water was caused by the mud, which was stirred up from the bottom by large rainfalls.

He also said the causes of fish kills were complicated but had nothing to do with pollution because the town had strict sewage control.


The level of dissolved oxygen in the water is lower than standard, which could have suffocated the fish to death, according to authorities from local fishery administration.
