摘要
1984年6月和1985年12月,对东海进行了首次黑潮实验性调查.整个调查区涉及到东海及东海黑潮区。作为综合调查项目其中之一的生物调查,在全调查区进行了取样:冬、夏两航次共采集浮游动物样品115份,经分析共鉴定出莹虾类4种。夏季(6月)出现中型莹虾 Luciferintermedius、正型莹虾 Lucifer typus、刷状莹虾 Lnckfer penicillifer、东方莹虾 Lucifer oriental-is;冬季(12月)出现中型莹虾 Lucifer intermedius、正型莹虾 Lucifer typus,可以明显地看出莹虾类的数量分布和种类分布与水温、营养盐、水团、流系等之间有密切的关系。并且莹虾类的数量分布与渔场的位置也有一定关系。据本次调查及资料分析,夏季可将中型莹虾作为东海混合水的指标种;正型莹虾可作为黑潮水的指标种;刷状莹虾可作为台湾暖流的指标种,为水文的调查提供较有价值的参考.
The first experimental investigation of the Kuroshio region of the East China Sea was conducted during January 1984—December 1985.The whole investigation area in- volves the East China Sea and its Kuroshio region,During the biological investigation, samples were taken throughout the whole investigation area.In winter and summer cruises the number of samples taken totalled 115.After analysis of the samples,4 species of the lucifer were identified.In summer,Lucifer intermedius,Lucifer typus, Lucifer penicilli fer and Lucifer orientalis were found;in winter,Lucifer intermedius and Lucifer typus occurred.In the light of population structure,quantitative distribu- tion and the distribution of different species,their relations to water temperature,salin- ity,water masses and current systems can be evidently seen and the reahion between the quantitative distribution of the lucifer and fishing grounds is still more evident. The denseness of the lucifer in the Kuroshis region of the East China Sea may pro- vide a definite reference to the investigatiori of the fishing ground of the East China Sea. Based on this investigation and data analysis,Lucifer intermedius may be used as an indicator species for the mixed water of the East China Sea in summer,Lucifer typus for the water of the Kuroshio region and Lucifer penicillifer for the Taiwan warm current, These indicator species may also provide valuable references to hydrological investiga- tion.
