Invasive aquatic species have been identified in Madagascar. “Currently, in Fort-Dauphin, a small parasitic crab is attacking our oysters, which represent an essential source of income for our local fishermen. Furthermore, we are also facing a proliferation of green algae. This is the case, for example, at the port of Toamasina, which is now completely invaded by these algae, thus impacting the entire surrounding maritime zone,” stated Ludovic Rizar, national focal point for the Biofouling test project, yesterday during the national workshop on in-water hull cleaning, organized by the Port, Maritime and River Agency (APMF), under the aegis of the International Maritime Organization (IMO) and the Maritime Technology Cooperation Centre for Africa (MTCC Africa), held on July 15 and 16, 2026, at the Novotel Ivandry.
Biofouling is scientifically identified as one of the main vectors for the spread of invasive aquatic species. These species severely disrupt local marine ecosystems. Mastering environmentally sound cleaning techniques helps to stop this threat and protect the unique biodiversity of the Great Island.
Economically, as highlighted by the Director General of the APMF, Jacquis Georges Rainimbahy, an optimally cleaned hull significantly reduces the hydrodynamic drag of ships, leading to a direct decrease in their fuel consumption and greenhouse gas emissions. Ultimately, this skill development guarantees better compliance with international standards and directly strengthens the competitiveness of the Malagasy maritime sector.
