Here, we demonstrate the temporal and spatial variations in plankton community which the standing stock and productivity in the Kuroshio are equivalent to those on the continental shelf. The standing stock of the plankton community in the Kuroshio fluctuated over time, with high autotrophic standing stocks in the spring and summer and high heterotrophic standing stocks in the summer. The appearance of low-salinity waters was associated with a change in plankton community structure and increased standing stocks of micro-autotrophs and mesozooplankton. Although mesozooplankton standing stock and productivity varied spatially, differences among continental shelf water (CSW), the Kuroshio path (KR), and the outside (OKR) were not significant. A cluster analysis of predominant copepods identified the three groups appeared across the CSW, KR, and OKR in the Tokara Strait. The coastal copepods were representative of these groups and their abundance is negatively correlated with salinity in the sampling layer. From these results, we propose that the plankton community in the CSW is advected to the KR and OKR, yielding high standing stocks and productivity in these regions.
