Much of the marine related traditional knowledge held by fishers in Vanuatu relates to increasing catches while managing resources of cultural, social and subsistence value. Traditional beliefs and practices associated with fisheries and their management follow natural cycles of resource abundance, accessibility, and respect for customary rules enshrined in oral traditions. Many management related rules that control fishers’ behaviours are associated with the fabrication and deployment of traditional fishing gear. A number of traditional beliefs, including totemic affiliations and the temporal separation of agricultural and fishing practices, serve to manage marine resources. Spatial-temporal refugia and areas of symbolic significance create extensive networks of protected freshwater, terrestrial and marine areas. The arrival of Europeans initiated a process of erosion and transformation of traditional cosmologies and practices related to marine resource management. More recently, the forces of development and globalisation have emerged to continue this process. The trend from a primarily culturally motivated regime of marine resource management to a more commercially motivated system is apparent, with the implementation and sanctioning of taboos becoming increasingly less reliant on traditional beliefs and practices. This paper reviews a number of traditional marine resource management beliefs and practices formerly found in Vanuatu, many of which remain extant today, and documents the transformation of these systems in adapting to contemporary circumstances. By documenting and promoting traditional management systems and their merits, it is hoped to advocate for a greater recognition, strengthening and support for these indigenous systems in Vanuatu and the region
