为了阐明微生物食物链在北极西部太平洋奥亚西奥地区放牧食物链中的重要性，在1997年7月和10月以及1998年1月、3月和5月对这两条食物链中组成生物的生物量进行了调查。根据生物量数据结合已发表的实验数据(Shinada等人，2000年)建立的浮游生物食物链内的碳流表明，初级生产在全年主要通过微生物食物链输送。只有在春季浮游植物大量繁殖的时候，放牧食物链才能与微生物食物链一起发挥作用。
In order to clarify the importance of the microbial food chain in relation to the grazing food chain in the Oyashio region, western subarctic Pacific, the biomass of component organisms in the two food chains was investigated during July and October in 1997, and January, March and May in 1998. Carbon flows within the plankton food chains, as established from biomass data combined with published experimental data (Shinada et al., 2000), suggest that primary production is largely channelled through the microbial food chain throughout the year. The grazing food chain is functional along with the microbial food chain only during the spring phytoplankton bloom.
