Sargassum muticum Research
Over half a century ago, a non-native seaweed called Sargassum muticum was accidentally introduced into Washington’s inland waters with oysters imported from Asia. The seaweed invaded the entire region, and can be found in lower intertidal and shallow subtidal rocky habitats throughout Puget Sound, the Strait of Juan de Fuca and the San Juan Islands.
