15.The population structure of zooplankton was investigated at Daxingkai Lake in May, July and September 2001. There were 32 species of zooplankton, in which rotifera (43.8%), protozoa (31.2%), cladocera and copepoda (25% ) were of the predominate.
16.In the model, 6 state variables (DIN, PO4-P, phytoplankton,zooplankton, organic detritus, and dissolved organic nutrients) were included.
17.In contrast, the estimated carbon flux of large copepods (>330μm) was high to 108.67mg C m -2 day -1 , making up 95.3% of the total macro zooplankton carbon flux. The fact that apparent carbon flux of macro zooplankton was 2 3 orders magnitude higher than phytoplankton carbon flux, displays an obvious feature of high zooplankton carbon and low phytoplankton carbon in the water column in the ice melting duration in Chukchi Sea.
18.The biomass of zooplankton in August was about ten times higher than that in September, at 239.1 mg m~(-3) and 24.7 mg m~(-3) respectively. Sagitta crassa contributed largely to total biomass. The distribution of biomass and individual density of zooplankton was highestin the middle of the study region where chlorophyll-a was lowest.
19.The average amount(based on the formula of zooplankton is 60.7 ind./L and average biomass(based on the formula is 0.6499 mg/L.In addition,this paper deals with the characters of horizontal and perpendicular distributions for zooplankton,and estimates the amount which acts as the bait for fishes.All these may help discorery the“raddle”of the“big red fish”。
20.The seasonal variation of phytoplankton,zooplankton and nutrients at a fixed sta-tion and in the Extended Gulf Stream System are studied by using a vertically averaged plankton model,respectively.
