摘      要：Brown tides have recurred in estuary areas globally,but trophic interactions between the causative species Aureococcus anophagefferens and planktonic copepods remain poorly *** this study,we investigated performance（ingestion,growth,development and reproduction） of the planktonic copepod,Pseudodiaptomus poplesia,offered either mono-algal or mixed-algal diets containing a Chinese strain of ***.A typical Michaelis-Menten pattern existed between ingestion rate and food level when copepod fed on the monoalgal diet of this *** exhibited the highest maximum ingestion rate（Imax） than copepodids and adult *** addition,Imax value was higher in nauplii feeding on *** than on Skeletonema *** fed mixtures of *** and ***,*** selected against *** cells,but less strongly at the naupliar *** did not undergo metamorphosis and died at late naupliar stages feeding on *** alone,similar to those under ***,the presence of *** greatly reduced the reproduction rate of females in mixtures but did not influence the growth rate of *** results suggest that *** nauplii may exert grazing pressure on *** population during a brown tide,which,however,may not be persistent because of copepod population decline.
