Abstract
  • Japanese salmon fishery is facing a juncture of existence and pressed for the improvement of constitution. The decline of high-seas salmon fisheries was taken and the import amount increased rapidly. In addition, domestic production by coastal set net fisheries has increased with a success of salmon enhancement in Japan. Salmon market has internationalized consequently, decreasing wholesale prices of domestic salmon in Japan. Factors on short-term and long-term changes in the wholesale prices of salmon at the main landing port in Hokkaido were examined. The wholesale price increased in the year when the landing amount of salmon decreased from the previous year. A negative correlation between the landing amount and prices of salmon at the landing port indicated that the prices of salmon were influenced by the landing amount. It was also that clarified that the import amount of salmon influenced the wholesale price of salmon. The wholesale price of salmon in the entire Hokkaido showed the long-term variability depending on the amount of imported salmon, and the wholesale price of salmon in the regions showed the short-term variability depending on the amount of landing salmon. Factors on wholesale price function of salmon in Japan were analyzed by econometric method. It was clarified that wholesale price of fresh salmon decreased when inventory amount of fresh salmon or import amount of fresh salmon increased and wholesale price of fresh salmon decreased when inventory amount of salted salmon roe and fishery production of fresh salmon increased. Increase in the inventory amount of fresh salmon in recent years was caused because of increase in the import amount of fresh salmon produced by aquaculture in winter.
