dc.description.abstract | To understand effects of the Yellow Sea Bottom Cold Water (YSBCW) on the vertical distribution of the copepod Calanus sinicus, we surveyed diel vertical migration (DVM) of C. sinicus at a fixed station in the Yellow Sea before and after formation of the YSBCW. Cold water (<10°C) was observed in the bottom layer when the water column was thermally stratified in summer, while the water column was thermally well-mixed in spring. Samples were collected from five different layers at 3 hour intervals with an opening-closing net. Identified developmental stages of C. sinicus were from copepodite I (CI) to adults (CVI). Adult females (1-155 inds.m-3) showed clear DVM through the whole water column in spring, whereas adult males did not migrate. DVM of CV was not clear, while CI-CIV showed maximum residence in the upper 10-20m layer with high concentration of chlorophyll-a (chl-a). Conversely, clear DVM was not found in adult females (< 30 inds.m-3) and adult males in summer. Maximum abundances of CI-CIV also occurred consistently in the subsurface layer (20-40m) with high concentration of chl-a. CV (1-272 inds.m-3) moved upward nocturnally to the near-surface layer (10-20m) with average temperature of 25.74°C, while it was not found in the surface layer (0-10m) with 28.31°C. These results indicated that existence of the YSBCW affected the vertical distribution of all developmental stages | - |
