Abstract
The development of fishery technologies supports food sustainability to achieve a steady supply of fish and fishery products. However, the priorities for research and development (R&D) in fishery technologies vary by region due to differences in fish resource availability, environmental concerns, and consumer preferences for fishery products. This study examines trends in fishery technology innovations using data on patents granted as an indicator of changing R&D priorities. To clarify changes in R&D priorities, we apply a decomposition analysis framework that classifies fishery technologies into three types: harvesting, aquaculture, and new products. This study mainly focuses on China, Japan, and Korea as the major fishing countries in the north-east Asia region. The results show that the number of fishery technology patents granted increased between 1993 and 2015; in particular, the number of aquaculture patents granted has grown rapidly since 2012. However, the trend in Japan was the opposite, as the apparent priority given to aquaculture technology innovation decreased between 1993 and 2015. The trends and priority changes for fishery technology inventions vary by country and technology group. This implies that an international policy framework for fishery technology development should recognize that R&D priorities need to reflect diverse characteristics across countries and the technologies employed.
Highlights
Fish and fishery products are important for maintaining a healthy diet [1] and are a major source of nutrition for hundreds of millions of people worldwide [2]
To decompose patents granted in the field of fisheries technology, we used three indicators: the priority of the specific fisheries technology (PRIORITY), the importance of fisheries technology in all patents granted (FISHERY), and the scale of research and development (R&D) activity (SCALE)
We propose a patent decomposition framework to distinguish the change in the priority placed on specific fishery technology innovations from that placed on total fishery technology innovations
Summary
Fish and fishery products are important for maintaining a healthy diet [1] and are a major source of nutrition for hundreds of millions of people worldwide [2]. This report expects that food fish supply per capita will increase in China, India, and Brazil by 19.5%, 11.7%, and 32.3%, respectively, by 2025, which is the target year for the global improvements in maternal, infant and young child nutrition outlined in the Rome Declaration on Nutrition [5]. This growth is expected to significantly increase worldwide demand for fish and fishery products
