摘要：

根据2004年7月-9月“国际903”号在北太平洋150°E～158°56′E、42°34′N～46°25′N进行秋刀鱼资源探捕所获得的浮游植物样本资料的分析、鉴定，在15个站点的海洋浮游植物样本中，共发现浮游植物17种，分别隶属于硅藻门和甲藻门。浮游植物生物量为8～1320mg/m^3，均值为432．5mg／m^3，变化幅度大，分布不均匀。分析认为水温、盐度是影响调查海域浮游植物的种类及分布的主要环境因素。

Abstract:

The investigation fishing of Pacific saury （ Cololabis saira） resources was carried out in The North Pacific Ocean （150°E -158°56′E ,42°34′N -46°25′N）from July to September, 2004. Based on the sample analysis and identification of phytoplankton, we got seventeen phytoplankton species in alll, belonging to Bacillariophyta and Pyrrophyta, respectively. The biomass of phytoplankton was 8 - 1 320 mg/m^3, with average value 432.5 mg/m^3. Analysis showed temperature and salinity were main environmental factors that affect the species and distribution of phytoplankton in the investigation area.
