IOI-SA joined the multi-stakeholder team, lead by the Ministry of Ocean Economy, Marine Resources, Fisheries and Shipping in Mauritius this July to investigate biofouling on ships in Port Louis. Biofouling is the attachment and growth of non-desirable organisms on the submerged surfaces of ships’ hulls. The growth of organisms not only slows down ships, resulting in an increase in fuel costs, but is also an important way in which the introduction of alien, invasive species to new areas can occur. It is therefore an ecological and economic threat to Ports. This was the second field visit for the project and included sediment sampling and sampling of hulls in Port. This project includes a large team from multiple organisations, including the Mauritius Oceanographic Institute, Shipping Division, Mauritius Ports Authority and National Coast Guard.
