东海绿鳍马面鲀群体及其分布

本文根据江苏省海洋渔业公司（１９７４－１９８９年）在东海的绿鳍马面渔获量（约１８．２万吨），结合东海水温等资料分析绿鳍马面在东海的群体分布，并作初步探讨。经分析表明：（１）东海的绿鳍马面冬季分布存在着明显的地理差异；（２）在冬季东海的该鱼种存在着三个地方群体，即东海群体、黄海群体和日本海群体；（３）在捕捞东海群体的马面纯时从渔获物中反映出它的组成结构变化，７０年代捕获的主要是剩余群体，８０年代后期捕获的则是补充群体；（４）钓鱼岛水域是该鱼种的东海群体的产卵场，保护该产卵场乃当务之急。

ON THE STOCKS OF FILEFISH NAVODON SEPTENTRIONALISAND THEIR DISTRIBUTIONS IN THE EAST CHINA SEA

This paper deals with the data of file fish yield(aboat 182000 tons)belonged to Marine Fisheries Corporation of Jiangsu Province from 1974 to 1989 inthe East Ohina Sea. In order to analyze their distributions, it was relative to thewater temperature of fishing grounds. The distributions of the fish Stocks havebeen discussed as well and the results are summarized as follows.1. During the winter season,in this widely regional sea the distribution of thefilefish exists obviously geographical differences.2. There are three local stocks in the East China Sea,namely,the East ChinaSea stock, Yellow Sea stock and the stock belonged to Sea of Japan.3. The fishing features of the East China Sea stock reflected the changes ofthe compositional strueture among the annual catches. In the 1970's the surpluscolony was the main part of the catch composition, and in the late of 1980's the recruit colony was the major part of the catch component.4. The adjacent waters of Diaoyu Dao Island is the spawning ground of the fishfor East China Sea stock. The protection measures for this spawning ground arethe task of top priority.
