Abstract: The changes in plankton structure and water quality indices were studied in marine high-place ponds with Pacific white leg shrimp Litopenaeus vannamei culture in Linghai coast,Liaoning province.It was found that average water temperature was 23.45℃,pH 8.16,and salinity 23.1,and that chlorophyll-a concentration showed a first elevated and then stable trend.The members in Bacillariophyta(accounting for 39.58%),Euglenophyta(20.83%),and Chlorophyta(18.75%)were the dominant species in phytoplankton and some species in Pyrrophyta,Cyanophyta and Cryptophyta were also observed in the high-place ponds.The phytoplankton in the highplace Pacific white leg shrimp ponds had density of 111×106cells/L,and biomass of 22.39 mg/L,with dominant members in Chlorophyta and Bacillariophyta,and different biodiversity including Shannon-Weiner index(H)of 0.46,and evenness index(J)of 0.13.For the zooplankton with dominant species in copepoda,there was density of 27.04 ind./L,and biomass of 0.629 mg/L,with Shannon-Weiner index(H)of 0.68,and evenness indexes (J)of 0.52.Canonical correspondence analysis(CCA)revealed that salinity,and PO3-4-P,total nitrogen content, total phosphorus,NO-2-N and NO-3-N contents were the main factors affecting the dominant phytoplankton community structure,and that salinity,pH,PO3-4-P,total nitrogen,NO-2-N and NH+4-N contents were the main factors influencing the dominant zooplankton community structure in the marine high-place ponds.The findings showed that the water quality in the marine high-place shrimp ponds was eutrophic,and instable community structure in the late culture period.
