Seasonal netzplankton samples from stations in the Changjiang (Yangtze River) Estuary were collected from May,2004 to February,2005.The dominant species and their contribution to the total zooplankton abundance were determined.Moreover,the relationship between the salinity and abundance was studied with stepwise linear regression.During the whole year,the salinity was positively correlated with the abundance,while the temperature,negatively.Linear regression analysis showed also a high positive correlation with salinity for total abundance in August and November,while in February and May,no obvious relations were found.The most abundant community was composed of neritic and brackish-water species.The North Passage (NP) (salinity
