本文采用个体重量计数法对黄海海区及各分区水域中的浮游桡足类的生物量及其组成进行了统计分析.结果表明,在浮游桡足类的生物量中起重要作用的有小拟哲水蚤Paracalanus parvus,大同长腹剑水蚤0ithona similis,中华哲水蚤Calanus sinicus,短角长腹剑水蚤0ithona brevicornis,强额拟哲水蚤Paracalanus crassirolris,双刺纺锤水蚤Acartia bifilasa,近缘大眼剑水蚤Corycaeus affinis及克氏纺锤水蚤Acartca clausi等8种.其中除中华哲水蚤体型较大外,其它7种均属中小型浮游桡足类.且其生物量的大部分是由2～4种桡足类的生物量所组成.
In this paper, the individual weight counting method was used to analyze the biomass and composition of planktonic copepods in the Yellow Sea and each sub-district waters.The results show that there is a small artificial philosophy that plays an important role in the biomass of planktonic copepods Dracaena paracalanus parvus, Datong daphnia daphnia 0ithona similis, Dwarf Calanus sinicus, 0ithona brevicornis, Paracalanus crassirolris, Acartia bifilasa, Corycaeus affinis, Acartca clausi, etc. Among them, 7 species belong to small and medium size pelagic copepods, except for Larvae spp., And most of their biomass By 2 to 4 kinds of copepods biomass composition.
