Outline of Final Research Achievements |
Harbour porpoise is strongly affected by human activities because its habitats is near shore. Wide range of researches are conducted in Europe and North America but little in Japan. Recently, stranding network and acoustic observation devices has developed in Japan, which enable to conduct new approach to the research of harbour porpoise. In the current study, specimens are collected from stranded and by caught harbour porpoise to analyse the diet and the conflict between fisheries. Also by using acoustic devices, observations are conducted around fishing gears to clarify the behaviour around the gears. From these result, conflicts between harbour porpoise and fisheries are described which will help to find a sound coexistence between cetacean and human.
