ABSTRACT : The punctuality of international container services have lowered substantially in recent years, causing a serious impact on global supply chain. One of the major causes is the concentration of callings of ships at specific ports and terminals accompanied by revision of shipping alliances. Arrival ships are forced to wait at offshore, if there isn't enough space for berthing because of delays of arrival ships or lengthens of staying times at congested terminal. This study estimated waiting time of ships calling at Japanese major container terminals by utilizing AIS data, and analyzed the result comparing with terminals at foreign countries. It was revealed that the average offshore waiting time volume was around 100 hour*TEU/m/month at Japanese major terminals and the ship sizes of waiting ships were smaller than those of calling ships.

ABSTRACT : Oyster house is very popular in Japan during the winter season. Oyster house provides the opportunities that make visitors enjoy local seafood, talk with fishermen, and understand marine environment. An understanding of such recreational value is important for the development of the fishery policy. This paper estimates economic value of oyster house in Hannan City using travel cost method. The oyster house produces 10 million JPY, which means that its recreational value is higher than the cost. Furthermore, the oyster house improved the familiarity of visitors toward fishermen, local fish, and marine environment according to the on-site questionnaire survey.

ABSTRACT: Towards sustainable use and conservation of marine resources, getting involvement of stakeholders is indispensable. The Mutsu Institute for Oceanography, JAMSTEC observes marine environment of Eastern Tsugaru Strait, where costal fisheries are active. Observed data are open to the public at a website named MORSETS. This study investigated usage of the data on MORSETS by local fishermen through semi-structured interviews. Major findings are that interviewees: 1) view the MORSETS data via smartphones for day-to-day fisheries, mainly on land before going out and 2) utilize the MORSETS data to judge timings of setting and withdrawing fishing equipment together with other information. Another finding is that they expect direct benefit from more specific information, tailored to targeted species and fishing methods. Comments of fishermen imply that degree of utilization and willingness to use marine environmental data would differ according to fishing methods. Furthermore, fishermen’s “local-knowledge” revealed by the interviews would promote co-design and co-deliver solution-oriented ocean research. The findings are useful for stakeholders who pursue collaborative research in other places. Further assessing value of using marine environmental data by stakeholders is necessary.
