摘要	The Yellow Sea(YS) and East China Sea(ECS) are highly dynamic marginal seas of the northwestern Pacific Ocean. To gain an in-depth understanding of zooplankton community structure,zooplankton abundance, biovolume, and size structure in summer 2017 in the YS and ECS were assessed using ZooScan imaging analysis. Zooplankton abundance and biovolume ranged 2.94–1 187.14 inds./m~3 and 3.13–3 438.51 mm~3/m~3, respectively. Based on the biovolume data of the categorized size classes of 26 identified taxonomic groups, the zooplankton community was classified into five groups, and each group was coupled with distinctive oceanographic features. Under the influence of the Yellow Sea Cold Water Mass, the Yellow Sea offshore group featured the lowest bottom temperature(10.84±3.42 ℃) and the most abundant Calanoids(mainly in the 2–3 mm size class). In the Yellow Sea inshore group, Hydrozoans showed the largest biovolume and dominated in the 3–4-mm and >5-mm size classes. The East China Sea offshore group, which was affected by the Kuroshio Branch Current, featured high temperature and salinity, and the lowest bottom dissolved oxygen(2.58±0.5 mg/L).The lowest values of zooplankton abundance and biovolume in the East China Sea offshore group might be attributed to the bottom dissolved oxygen contents. The East China Sea inshore group, which was mainly influenced by the Zhejiang-Fujian Coastal Current and Changjiang Diluted Water, was characterized by high chlorophyll a and the largest biovolume of carnivorous Siphonophores(280.82±303.37 mm~3/m~3). The Changjiang River estuary offshore group showed the most abundant Cyclopoids,which might be associated with the less turbid water mass in this region. Seawater temperature was considered the most important factor in shaping the size compositions of Calanoids in different groups.
