A dead shoal of fish — first spotted in a Stockport park — has environmental officers scratching their heads.
Photos on social media show a large amount of fish in a pond in Bramhall Park, which were discovered recently.
The dead fish were expected to be removed by council officers on Tuesday (December 21) — but bosses from the authority, Environment Agency, and United Utilities are ‘at a loss’ to explain the cause of death.

A council spokesperson told the Manchester Evening News that the environment and water agencies are ‘convinced’ the cause of death was not pollution, but have not been able to ascertain the real reason for the fatalities.
“Stockport Council is aware of the recent incident in Bramhall Park where a high number of fish have been found dead in one of the ponds,” a statement said.
“The Council’s Countryside Officer has had site meetings with the Environment Agency’s fisheries officer and enforcement team along with an operative from United Utilities, in order to try to ascertain the cause of death and to establish whether or not it is related to a pollution incident.

“Both the Environment Agency and United Utilities are convinced that this is not a pollution incident but are at a loss as to how the fish have died.
“A florescent green tracer dye has been added to the ponds in order to trace the water movement through the pond system.”
