So far no scheme on how to compensate the fishermen suffering the loss has been finalized, an Anhui Province-based newspaper reported on Tuesday.

On August 29, Yongcheng County in central China's Henan Province, which is in the upriver area of Anhui's Huaibei and Suzhou cities, opened its Zhangqiao sluice to release water after industrial waste and sewage had been stored for a long time.

The polluted water flooded the downriver Huaibei's Tuohe River and Suzhou's Xinbian River, killing the large number of fish in the two rivers, the report said.

Local fishermen report more than 450,000 kilograms of fish died in the pollution.

Preliminary estimates showed the pollution resulted in financial losses of more than three million yuan (US$375,000).

Local fishing authorities are checking with fishermen to work out a final figure.

Anhui provincial environment authority reported the incident to the State Environmental Protection Administration.

Last month, a task force formed by state and regional environment authorities investigate. The task force also organized local authorities to check the water quality of two rivers and to inspect pollution-prone companies and local sewage treatment facilities.

The state administration also required authorities in Henan and Anhui to establish a joint mechanism to prevent such incidents in future.
