Abstract text

Snow crab (Chionoecetes opilio) is one of the commercially most important crab species in Japan, and its fishing activities take place in the 36°N - 45°N latitude range. There are four stocks within Japanese exclusive economic zones, of which the two largest stocks are shared with Russia and South Korea. Japan also serves as an important market for snow crab and imports from both of these countries. In particular, Japan imports a large amount from Russia, with 5-year average annual imports of snow crab amounting to 16,617 metric ton. This study investigates the linkages between foreign fisheries management and domestic fishing activities when both the stock and market are shared. In particular, we examine the impacts of Russian IUU fisheries regulation on Japanese snow crab fishing activities by using Japanese trade statistics and landing statistics from major domestic ports. There are two possible outcomes. First, Russian crabs being substitutes to domestically caught crabs, more stringent IUU regulation in Russia increases the ex-vessel prices at Japanese domestic ports. Second, more stringent IUU regulation increases the cost of production for Russian fleets, which creates a favorable condition, and thus, higher catch for Japanese fleets that share the stock with Russia. Therefore, the real resource conservation effect of the Russian IUU regulation may be smaller than it appears in the trade statistics.
