Marine traders learn about Carpet Sea-Squirt

From Port of Jersey
8th August 2023

Ports of Jersey recently teamed up with Government to host a talk for local marine traders on the emerging problem of Carpet Sea-Squirt, which has been found beneath several pontoons and boats in the Elizabeth Marina.

The talk, given by marine expert Chris Isaacs from the Infrastructure and Environment Department, focussed on the safe removal and disposal of this invasive species, and how to avoid it spreading to other boats and equipment.

The group looked at examples of the organism and learned how to report any sightings to the Natural Environment team or Ports of Jersey.

Further surveying of Elizabeth Marina, other harbours, and other parts of the coast is underway to assess the extent of the infestation.

Advice for mariners 

  • Check your equipment, boat, and clothing after leaving the water for mud, aquatic animals or plant material. Remove anything you find and leave it at the site.
  • Clean everything thoroughly as soon as you can, paying attention to areas that are damp or hard to access. Use hot water if possible.
  • Dry everything for as long as you can before using elsewhere as some invasive plants and animals can survive for more than two weeks in damp conditions.
