在200海里体制下,日本海洋渔业产量近几年仍维持在1100万吨左右,其中约有900万吨产暈来自沿岸、近海渔业,可见200海里以内水域渔业生产惊人的发展程度。但从渔获种类看,拟沙丁鱼占了400万吨左右,其他种类变化不大,且多呈现下降趋势。在本世纪四十年代后期,日本当时正处在第二次世界大战后混乱时期,粮食供给非常紧张,为此,在陆地增产稻米的同时努力从海洋中获取水产品以弥补粮食的不足。但那时日本周围海域的拟沙丁鱼资源正值三十年代中期大丰产之后的衰退期。为了提高
Under the 200-nautical mile system, the output of marine fisheries in Japan has remained at 11 million tons in recent years. About 9 million tons of them have been produced from seas and coastal fisheries, showing an alarming increase in the production of fisheries within 200 nautical miles. However, from the catch types, the proposed sardines accounted for about 4 million tons, while other types of changes did not change much, and more downward trend. In the late 1940s Japan was in the chaotic period of the Second World War and its food supply was so tense that it endeavored to make aquatic products available from the oceans while supplementing it with land to make up for its deficiencies. At that time, however, the proposed sardine resource in the sea area around Japan was at a time of decline after the bumper crop of the mid-1930s. To improve
