The Department of Infrastructure says it doesn't have any responsibility for cleaning up seaweed.
Infrastructure Minister Tim Crookall was asked in House of Keys this week by Arbory, Castletown and Malew MHK Jason Moorhouse about it.
Mr Moorhouse wanted to know who removes excess seaweed from harbours and beach areas, if not local authorities.
The minister spoke about how it's managed instead:
Yacht club worries over lifeboat retirement
One nuisance cyclist ticketed in more than three years
New ministerial post created by chief minister
Huge floating book fair to arrive in Douglas next month
Stay safe for Hop Tu Naa tonight
Special Olympics fundraiser needs you
Peel ready for bonfire and fireworks later
Government: "UK never told us about child murderer"
