The variation of zooplankton community under the control of dike gates in the dam constructed estuary

초록

To investigate the influence of the freshwater on the variation of estuarine zooplankton community under the condition of estuarine dike, we collected microzooplankton and mesozooplankton samples during wet seasonin the Youngsan Estuary, Korea . During wet season including typhoon raining event, the range of salinity was fluctuated from 3.5 to 27.5psu by the large discharge of the freshwater when the gates of dike were opened,whereas the ranges were 25.2 to 33.2psu in the closed gates.
