올 3월 일본 해양정책연구재단(Ocean Policy Research Foundation : OPRF)이 북극에 관한 추진 시책을 발표했다. 국제법, 안전보장, 과학조사, 조선, 해운, 기상관측 등 각 분야의 전문가들로 구성된 '일본 북극해 회의'가 지난 2년 동안의 연구를 통해 일본정부가 북극의 지속가능한 이용을 위해 추진해야 할 정책 방향을 제시한 것이다. 이번 보고서는 행정조직 선박 및 항로 지구환경 안전보장 자원개발 국제물류 국제협력 등 북극 전반을 다룬 일본의 종합적인 정책으로, 일본 해양정책연구재단은 이번 보고서에서 북극해를 전담할 전담조직 신설, 새로운 해상방위 대책 수립, 러시아와의 협력 강화 등 9가지 정책 방향을 제시했다.

The East China Sea is an important region as nursery and spawning grounds for pelagic fishes such as jack mackerel, common mackerel etc. , and thus constitutes a major fishing area for purse-seine fishery. The environment surrounding in this region is under the influence of the Yellow Sea Cold Water, China Coastal Water and Kuroshio Current. The purpose of this study was to clarify the effects of oceanographic conditions and thermal fronts on the formation of the fishing grounds for the mackerels in the East China Sea. Through the analyses of fisheries statistics during 1968-1976 and temperature data, the following facts are found: 1) Approximately $70\%$ of the total mackerel(common) catches appeared to be come from the Tsushima Current region which includes Sakai coast of the Japan Sea, eastern Tsushima and Shirase Island, and Jeju Island of Korea. This area covers only about $8\%$ of the East China Sea. 2) Main fishing grounds for the jack mackerel are also centered around the area of southwestern Goto, Shirase and eastern Tsushima Island where the catches accounted for about $54\%$ of the total jack mackerel catches. 3) Fluctuations in annual catches are relatively small in the Tsushima Current region, compared to other regions such as Yellow Sea, southwestern coast of Kyushu and mid-western part of the East China Sea, where the fisheries yields varied considerably due to unstable fishing conditions. 4) It appears that the fishing grounds for the jack mackerel are mainly distributed along the warmer region ($15-20^{\circ}C$) of the thermal front, and those for the common mackerel are in somewhat colder region ($13-16^{\circ}C$) in the Tsushima Current.
