Zooplankton community structure of the sea surface microlayer near nuclear power plants and marine fish culture zones in daya bay

摘要

The authors' surveys in May-June 1999 (two cruises) at six sampling stations near nuclear power plant s(NPP) and marine fish culture zones in Daya Bay, Guangdong, revealed species composition, densities and body-size of the sea surface microlayer (SM) zooplankton (>35 μm). Results showed that protozoans and copepod nauplii were the predominant components, accounting for 65.40/100 to 95.56/100 of total zooplankton in abundance. The size-frequency distributions showed that the frequency of micro-zooplankton (0.02-0.2 mm) reached 0.8235.
