| Outline of Final Research Achievements |
For the sustainable use of fisheries resources, feeding pressure of baleen whales is not negligible. However amount of feeding and species of prey could be observed in stomach contents by capturing of these species. Present study revealed that the feeding events of blue whales and humpback whales could be observed directly using acoustic biologging technique. In addition, three dimensional reconstruction of underwater feeding behavior was conducted. Analysis of the vocalizations logged on the animals provided phonating rate and source levels, which is published in an international scientific journal.
