The study was carried out by a postal questionnaire survey and an aerial survey, commencing in October 1987. About 600 copies of the questionnaire were circulated in Vanuatu, and about 1000 kilometres of coastline surveyed from the air. Dugongs were reported or seen to occur in nearly 100 localities, including all the major islands and island groups of Vanuatu. The animals were generally reported to occur in small groups; only in three instances were groups of more than 10 animals reported. Most people reported that dugong numbers were either unchanged or were increasing. There was no evidence that dugongs migrate large distances or between islands in the archipelago, although movements may occur along the coasts of islands and between closely associated islands. Dugong hunting was reported from only a few localities, although it is caught in more areas if the chance occurs. Most hunting methods use traditional means, mainly the spear. Overall, hunting mortality is low, even in areas reported to regularly hunt dugongs. Accordingly, the dugong does not seem to be an important component of the subsistence diet in any part of Vanuatu, even though it is killed mainly for food.
