An invasive species of worm that can damage marine infrastructure has been found on boats on the Isle of Man.

The non-native Australian or trumpet tubeworm was discovered on the hulls of two boats in Ramsey that had been lifted from the water for cleaning.

The Department of Environment, Food and Agriculture (Defa) said the fast-growing species can be difficult to control and threatens biodiversity.

Manx harbour users have been asked to report any further sightings.

Scientists took samples after a crane operator spotted the unusual growth while cleaning the boats.

A Defa representative said harbour keepers would be stepping up the monitoring of where vessels have been and undertaking more checks in response to the arrival of the worm, which attaches itself to "man-made surfaces by developing thick layers of calcareous tubes"

Defa member Michelle Haywood MHK said invasive species were "one of the biggest threats" to the island's biodiversity.

She said boat owners should be vigilant as the worm can "spread from place to place attached to boat hulls, marine equipment and in bilge water" and the cost of removing invasive species could be "significant".

Defa said boat owners should check equipment, clothing and their boat for any mud, plant material or aquatic animals when leaving the water and thoroughly clean and dry boats and equipment to manage the risk.
