摘    要:根据2006-2007年4个季度机轮底拖网禁渔区线内侧及毗邻海域拖网专项调查数据,研究目标区内小黄鱼资源时空分布特征及相关规律。(1)江苏近岸海域小黄鱼产卵、索饵群体以南黄海群为主,东海群为次,黄渤海群影响甚微;(2)小黄鱼生物量高发生期为春、夏两季,夏季大幅高于春季,秋季高于冬季;(3)分布区随季节推移总体呈现北延趋势,而秋季至冬季北移迹象明显;(4)全年总体发生量,中南部的辐射沙脊群及邻近区域远高于中北部区域,但冬季则相反;(5)近长江口南部局部区域为南黄海群和东海群种群组成的混栖群体,四个季节生物密度稳定;(6)趋于性成熟群体春季陆续洄游至目标区产卵、孵化,幼体夏季在目标区出现较密集分布,但随时间推移幼鱼群体呈逐步分散趋势,目标区不是稳定的索饵场。

关 键 词:小黄鱼  资源群体  地理种群  禁渔区线内侧  时空分布  江苏近岸

Abstract:Based on the bottom trawl surveys in four seasons from 2006 to 2007 inside bottom-trawl fishing forbidden zone line of Jiangsu sea area and the near zone,we explored the temporal and spatial distributions of Larimichthys polyactis Bleeker resources in this target area,as well as their mechanism.The results showed that:(1) spawning and feeding groups in offshore areas of Jiangsu Province were composed of South Yellow Sea population mainly,with East China Sea population and smaller Yellow-Bohai Sea population...
Keywords:Larimichthys polyactis Bleeker  resource group  geographical population  inside bottom-trawl fishing forbidden zone line  temporal and spatial distribution  offshore areas of Jiangsu Province
