| Research Abstract |
Wild dolphins living in coastal area have been influenced by the recently-increasing human activity. It is still difficult to measure longitudinal effects on wild dolphins, such as declining growth rate or bad nutritional condition by worsening habitat environment, or shortening communication range by increasing background noise level because there are few methods to measure such data from free-ranging wild dolphins. In this study, we developed basic non-invasive methods for measuring 3-D body size of wild dolphins and the non-invasive system for measuring sound source level of dolphin sounds. These technique and system will contribute to monitor wild dolphin population for conservation.
