Abstract: The zooplankton was observed in four overwintering seawater ponds in the Liaohe River Delta Branch at Panjin Guanghe Crab Industry Co.,Ltd.from November2010 to March 2011.The zooplankton in these overwintering pondswas found to bemainly composed of protozoa,rotifers,copepodswhich were themain components.Protozoa predomanntly includesStrobilidiumgyrans,Didiniumbalbianii,Tintionnopsistoxantinensis,EuplotesmuscicolaandTintinnidiumentzii,with a density of 285.03 ind./L.The rotifermainly includedSynchaetalakowitzianaandS.tavina,also a small amount ofBrachionusplicatilis,with a density of116.87 ind./L.Copepodsmainly includedEurytemoraaffinis,E.pacifica,Sinocalamustenellus,S.laevidactlusandClausocalanusfurcatus,62.87 ind./L. There was only one kind of polychaetes—Polydoraligni,and all of them were larvae,with a density of 32.56 ind./L.The biomass of copepods was the maximum in the four overwintering seawater ponds.When they make blooms,itwas helpfull reducing the depleting factor by controlling the number ofmicrozooplankton,such as rotifer; but their own consumption of oxygen was a main depleting factor in the overwintering seawater ponds.This study used filtration approach by pumps and silk screen mesh and limited the number of copepods effectively.The ultimate goal was to promotwater dissolved oxygen level and phytoplankton biomass rising day by day.Itwas considered that clearing the sediment and disinfecting the water as a good way to limit the number of copepods at the beginning of overwintering.
