Ocean’s Oasis is a registered NGO that was created to explore the potential for a seaweed industry in Costa Rica and to promote the development of seaweed-related businesses in the country. We are currently conducting an investigation to determine the viability and growth of several native species of seaweed in Jobo, Guanacaste. Our objective is to determine whether the seaweed harvested can then be used to create new businesses, and thus kickstart a seaweed industry.
