| Outline of Final Research Achievements |
Environmental deterioration in the coastal area become serious in Japan. Snapping shrimp that makes peculiar pulse sounds are able to find along coastal area. Our laboratory has developed a new environmental indicator called pulse counts (pulse sounds / minute) for the evaluation of coastal environment. The purpose of this study is to investigate the distribution of snapping shrimp along the Japan coastal area and to evaluate the snapping shrimps habitat caused by impact of environmental change.
We observed the pulse counts from 2012 to 2015 at 66 coastal sites along the Sea of Japan. The pulse sound of snapping shrimps were observed in all regions in summer, but weren’t observed in Hokkaido in winter. Fixed-site monitoring of biological habitat by this method was able to show that it is available anywhere in Japan coastal areas. And the pulse counts per unit area (pulse counts/minute/area) were calculated from the water acoustic receive area using GIS for compare with several sites.
