远东拟丁鱼是西北太平洋的重要渔获对象之一,近年来渔获最持续增长,成为世界上单种鱼类渔获最最高的鱼种。据1983年的统计,在西北太平洋各海区,中、上层鱼类的渔获量已达7,077千吨,其中远东拟沙丁鱼独占4,222千吨,约占59％。目前,这一资源主要为苏、日两国及南朝鲜所利用。八十年代以来,远东拟沙丁鱼的异军突起引起了有关国家的关注,苏日两国开始合作研究远东拟沙丁鱼的洄游和分布。调查首先在日本太平洋沿岸和千岛群岛,北纬35°～47°,距海岸100～120海里的范围内展开。在调查海区的最南端,靠近房总半岛和偏北的金华山半岛,远东拟沙丁鱼 FISH is one of the important catch objects in the Pacific Northwest. In recent years, the catch has been continuously increased, making it the highest fish species in the world. According to the statistics of 1983, in the various areas of the Northwest Pacific, catches of the upper and middle fish reached 7,077 kt, of which 4,222 kt was the exclusive item of sarmentos in the Far East, accounting for about 59%. At present, this resource is mainly used by the Soviet Union, Japan and South Korea. Since the 1980s, the sudden emergence of the proposed sardines in the Far East has drawn the attention of the countries concerned. The two countries have started to cooperate in studying the migration and distribution of sardines in the Far East. The survey was conducted over the Pacific coast of Japan and the Kuril Islands between 35 ° -47 ° north latitude and 100-120 nautical miles from the coast. In the southernmost part of the survey area, close to the Fangzhan Peninsula and the northward Jinhua Peninsula, the Far East proposed sardines
