Biomass Assessment and Resource Science Service

Across each of our harvesting regions worldwide, we conduct long-term monitoring of the stock and conduct research on the potential impact of the harvest on the habitat architecture and associated fauna. Using state-of-the-art technology, such as high-resolution satellite imagery and drone photography, we map the shoreline’s distribution of seaweed beds. Extensive ground truthing is also carried out to determine the biomass in each bed. All this information is finally fed into a GIS platform for an accurate and functional visualization of the information.

In all our harvesting jurisdictions we follow a precautionary approach to the harvest. We use an area-based management strategy and subdivide the coastline into small management units. Each management unit has its own harvest quota that is set using a harvest rate well below the annual rate of re-growth. Close interaction with government departments and agencies, and a strict adherence to their guidelines, ensures the sustainability of the seaweed resource in all our harvesting areas.
