SuriaLink SeaPlant Utility Rating
Alginate source - source of fucoidan - wild harvest.
Careful management of harvest required to prevent habitat damage.
Ecklonia species usually possess a massive holdfast that extends into a long, hollow, gas-filled stipe up to 15 m in length. The stipe ends in a gas-filled bladder that extends into a flat, solid primary frond from which secondary fronds emerge. These secondary fronds can quite reach 3 m in length. Because of its hollow stipe and bladder this genus is generally floats at the sea surface.
Generally attaches to rocky substrate in subtidal regions along exposed seacoast.
