A microcosm experiment was conducted to study the impacts of different cultivation density of Cristaria plicata and Anodonta woodiana on nutrients and phytoplankton in a eutrophic reservoir(Dashahe Reservoir,South China),from May 31 to June 20,2009.The experiment was aimed to investigate the possibility of applying bivalve in controlling algal biomass in warm water bodies.The results showed that the concentration of total nitrogen,total phosphorus and chlorophyll increased and ammonia decreased in the two bivalve species treatments.Evident changes in phytoplankton were observed not only in biomass but also in community structure in terms of species composition.The percentage of Chlorophyte increased rapidly throughout the experiment.No significant difference existed between the two bivalve species groups,except that the time response differed under different effect intensity.The results suggest that C. plicata and A.woodiana may not be used as efficient manipulated organism to control eutrophication and improve water quality in reservoirs of South China.
