Invasive aquatic species have been identified in Madagascar. "Currently, in Fort-Dauphin, a parasitic crab is attacking our oysters, which represent an essential source of income for our local fishermen. Furthermore, we are also facing the proliferation of green algae. This is the case, for example, at the port of Toamasina, which is today completely invaded by these algae, impacting the entire surrounding maritime zone," declared Ludovic Rizar, national focal point of the Biofouling pilot project, yesterday, during the national workshop on in-water hull cleaning, organized by the Port, Maritime and Fluvial 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 seriously disrupt local marine ecosystems. Mastering ecologically sound cleaning techniques makes it possible to stop this threat and protect the unique biodiversity of the Great Island.
On the economic front, as emphasized by the general director of 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 skills development guarantees better compliance with international standards and directly strengthens the competitiveness of Madagascar's maritime sector.
