Sea cucumber exploitation in the Toliara region of southwest Madagascar
Résumé
Sea cucumber harvesting is a traditional activity in Madagascar (Conand et al., 1997) and is very actively pursued in the south-west (Toliara). Several sources (e.g. Provincial Trade Department, Provincial Marine Fisheries Service) indicate that, between 1979 and 1986, exports fluctuated between 10 and 56 t. Data on recent exports show a very large increase, with volumes of more than 500 t. However, available data are insufficient to diagnose and analyse current over-exploitation, as the fishing sector is quite complex, and analysis at several different levels is needed (Conand, 1997a and 1997b). For these reasons, a study was undertaken by the Fisheries and Marine Science Institute (IH-SM) to monitor fishing, fishery organisation, catches and marketing in two separate villages. The original results were reported in a post-Master's-level thesis (Rasolofonirina, 1997).
