ENVIRONMENT Agency experts are investigating after more than 700 fish were killed in a suspected pollution incident near Stone.
Staff are still at the scene after the incident on the Trent and Mersey Canal at Meaford.
An EA spokeswoman said: “We are currently dealing with a fish kill incident on the Trent and Mersey Canal near the former Meaford Power Station in Stone, Staffordshire.
"Our investigation into the cause of this incident is ongoing.
"We are also assessing the environmental impacts – our current estimates indicate that over 700 fish have died and approximately 300 metres of the canal has been affected."
The incident was reported to the Canal and River Trust on Tuesday June 10, and EA staff have been pumping oxygen into the canal since to try to save the remaining fish, as well as rescuing those found alive.
“We are increasing the oxygen levels in the canal to try to save as many fish as possible by using our oxyjet units to pump more oxygen into the water," the spokeswoman added.
"The Canal & River Trust carried out a fish rescue last night (Wednesday) and saved 1,560lbs of fish from the affected area of the canal – they are also helping us pump more oxygen into the water.
"We are continuing to take samples and monitor the situation."
