Japan’s priority given to Aquaculture technology innovation decreased in northeast Asia major fishing countries

January 19, 2018

The research group of Organization for Marine Science and Technology at Nagasaki University and Institute of Aquaculture at University of Stirling investigates the priority change of fish and fishery technology invention. This study examined the trend and priority changes in fisheries technologies using patents granted data in the world from 1993 to 2015. They focused on the following three technologies: (1) harvesting technologies, (2) aquaculture technologies, and (3) new products technologies. They clarified priority shifts, as reflected in the patents covering innovations in these three technologies, by applying the decomposition analysis.

The major finding is that Japan’s priority given to aquaculture technology innovation decreased between 1993 and 2015 even though that in other fishing countries rapidly increased. This result for the R&D strategy of fishery technologies is unexpected because Japan is one of the major fish consuming countries and international treaties and agreements for marine resource management become stricter in recent year. This information sends a key message to the Japanese government to recognize the necessity of promoting aquaculture technology development in Japan.
