Abstract
The fish catches have been decreasing and the average age of fisherpersons has increasing in recent years in Japan. It is urgent issue for the sustainable fishery to clarify the conventional expertise and to transform it into the formal knowledge. This research is aimed to visualize the expertise of the coast fishery in Higashi-matsushima, Japan. Three steps are applied based on SCOPE project by Ministry of Internal Affairs and Communications, MIC, Japan. 1) To exploit tacit knowledge: Interviews to fisherpersons, researchers, concerned organization, etc. are executed to acquire the procedures of coast fishery including the related data (open and/or personal), etc., 2) To survey the public data: The literature review and data survey are done to make the list of the available data, and 3) To transform the tacit knowledge to the formal knowledge: Constructing the framework of the all knowledge according to the coast fishery. Results are; 1) The list of available data is completed. Most of the data is on the web and the time interval is one hour or more. The local data, e.g. within several km2 is rare, 2) For the set net fishery and the gill net fishery, the assessment of the most promising net position is based on the location of ‘Shiome’ that is the boundary of the different mass water that gives the stress to fishes because of the temperature difference, etc., and 3) As the future work, the detection of the location ‘Shiome’ is necessary to achieve more efficient fishery operation
