Free-living marine nematodes were studied in the southern Yellow Sea Cold Water Mass (YSCWM) in June and November 2013.
Community structure of nematodes had no significant differences in YSCWM between the two seasons, except for the order of dominant species.
Epigrowth feeders were dominant in terms of species number and abundance in the sampling area.
Sediment phaeophorbide, bottom water salinity and temperature were the most important factors related to nematode community structure.
