Almost 400 fish have been killed in the latest pollution incident in Manx rivers.

Dead salmon and sea trout were found in the Laxey River between the Woollen Mills and the Shore Hotel.

Fisheries staff found the source of the pollution and removed the poisoned fish, and the authorities are now seeking to prosecute those responsible.

Environmental pollution officer at the Department of the Environment Dr Phil Styles (pictured) says it could have a serious impact on stocks: "(It affected) a significant number, hundreds in fact, of large, mature salmon and trout, and smaller fish and eels.

"Obviously any loss of fish of that age, mature salmon, is significant. What can be done about it at this stage I don't really know, but it's a great shame because obviously these fish could have spawned later in the year."

The dead fish were found last Friday.
