| Research Abstract |
We carried out the development of monitoring methods on marine life and their environment and promoted various field observations in Shiretoko World Natural Heritage (SWNH) area. As a result, it is clear that there is difference in primary production system between northern coastal region and southern coastal region. We clarified 1) the effect of Pacific salmon (Genus Oncorhynchus) escapement on supply of marine-derived nutrients to the riparian ecosystems using the stable isotope analysis, and 2) to estimate escapement dynamics and spawning carrying capacity of the wild pink salmon (O.gorbusha) relating to the feeding behavioral pattern of brown bear (Ursus arctos) in SWNH area. Based on the adaptive marine ecosystem management, we proposed new method to evaluatean optimum fisheries operation for each fish species using both catch of fish and haul of fish in the Shiretoko coastal fisheries.
