Abstract
Whale sharks are known to occur in Malagasy waters although very little research has been completed to further document the species. In order to increase the current national knowledge of the species, it is planned to conduct whale shark surveys in Madagascar. An initial investigation based on interviews of local fishers and dive operators was completed to establish the logistical baseline for such surveys. It was found that whale sharks are present around the majority of the Madagascar coastline but most known sightings have occurred along the north-western coast. In Nosy Be, it appears whale sharks occur all year round, particularly during planktonic blooms. Plans for further assessment involving a combination of boat based observations, photo identification, and acoustic and satellite tagging are described. © 2006 Elsevier B.V. All rights reserved.
