Hundreds of dead fish were found floating in the Ganga river at Shukhra area here on Sunday, promoting district authorities to launch a probe.
The fishes were suspected to have died due to discharge from industries, government officials said here.
Sub Divisional Magistrate (SDM) Umesh Mishra told reporters that the sample of the Ganga river water was collected and will be sent for test.
Meanwhile, some social and religious activists staged ‘dharna’ and demanded action. They also gave a memorandum to the SDM.
