Developed by the Centre for Resource Management and Environmental Studies (CERMES) University of the West Indies, the sargassum uses guide serves as a resource for researchers, business entrepreneurs, and policy makers by providing, under one cover, a comprehensive overview of the wide range of current uses of sargassum in the Caribbean and challenges faced to date. It also provides insight into potential uses based on examples and research from other parts of the world using different sargassum species or other seaweeds.
