Abstract

The breakdown of the Korea-Japan fishing negotiations since 2016 has made it impossible for many domestic fishing vessels to operate in the Japanese EEZ water, and large purse seine fishing vessels are one of them. Mackerel is a highly migratory fish species, circulating in the East China Sea, South Sea, West Sea, and East Coast throughout the year, and goes through a period of wintering, spawning, growth, and feeding migration and according to the breakdown of the Korea-Japan fishing negotiations it is located in the southern, eastern part of Jeju, or near Tsushima. As fishing became impossible it had influenced on the fishing of mackerel by large purse seine fisheries. In this study, in order to find out the dependence of large purse seine fishing vessels on mackerel fishing in the Japanese EEZ waters, we analyzed the characteristics of mackerel catch and value fluctuations in large purse seine fisheries for 15 years, and catch of mackerel by large purse seine fisheries in the Japanese EEZ waters from 2010 to 2016. The catch and fishing details were investigated. The total catch of mackerel by large purse seine fishery the average catch rate of mackerel in Japanese EEZ is 4 percent per year. The amount is estimated at 10.2 billion won per year. Although there was an effect, it was not judged to be a significant factor, and it was found that the amount of catch and fish price in the domestic waters had a greater influence on the total catch than the Japanese EEZ waters.
