FISH in a stretch of canal near Stone are safe again after a mystery pollution incident.
A joint operation by the Environment Agency and the Canals and Rivers Trust over the past two days has pumped oxygen back into the water.
An Environment Agency spokeswoman said: “We have successfully increased the oxygen levels in the canal so that the fish in the affected area are no longer in danger.
“We have removed all our equipment and will continue to investigate the cause of this incident.”
Dead and dying fish floating on the surface of the Trent and Mersey Canal near the old Meaford power station site were reported to the Canals and Rivers Trust on Tuesday, June 10.
It is estimated that more than 700 fish died and a 300 metre stretch of the canal was affected.
The Canal & River Trust carried out a fish rescue on Wednesday and saved 1,560lbs of fish from the affected area of the canal.
EA staff spent two days pumping oxygen into the canal using special oxyjet equipment to try to save the remaining fish, as well as rescuing those found alive.
Anyone with information about the cause of the incident should contact the EA on its 24-hour incident hotline 0800 807060.
