Salmon farming in Japan has been developing rapidly in recent years. In this paper, the backgrounds and actual situations of this industry are reported. Salmon farming had spread all over Japan as a result of the 2011 Great Earthquake. There are three types in this industry. New entering enterprises, yellowtail farmers and integrator companies in fish farming industry. In this industry, freshwater and saltwater farming are strongly combined into one integrated industry. There are some problems and difficulties in this industry. However, with huge global market it can be a successful fish farming industry even in Japan. Also, it will have positive impacts on many areas, both inland and coastal areas.

Salmon is one of the most familiar fish in Japan. Although the public has historically been prohibited to catch salmon by various social systems or laws, local society have had considerable cultural connection with salmon. We discuss about the social function of salmon in the Sanriku area revisiting some historical records on marketing or distribution of salmon in this paper. Salmon have a rarity with high cultural and social values long time in the Sanriku area and were used for gifts in various forms between various geographic scales from neighborhood to distant areas. Distribution of salmon is one of the factors constituting the cultural and social function in Sanriku area.

Modern fisheries industry requires human resources with specialized skills and high-end technique for its fundamental function and further development. Yet, the contribution of university education in fisheries to the industry has not been documented. This research, therefore, focused on elucidating the transition of the education program in fisheries and discovering its interaction and effectiveness towards the industry. This research revealed that the fisheries field has been undermined in this education level as the scale of the industry has diminished. Changes in the fisheries education program are linked to the development of capture fishery, though its contents hardly relate to how graduates would contribute to society within the broad definition of “fisheries”. Demand in human resources for the industry within this new definition should be included in the rearranged educational program.
