AbstractWe evaluated the toxic effect of Microcystis aeruginosa on Daphnia carinata King using survival rate, population growth rate, and body length. When fed Microcystis aerugionsa PCC7820 and liberated colonial Microcystis spp., all D. carinata died within five days. When fed a mixture of M. aeruginosa PCC7820 and the green alga Scenedesmus obliquus, the survival rate, population growth rate, and body length of D. carinata generally increased. The survival rates were all above 80% after ten days. However, with liberated colonial M. aeruginosa, the toxic effect on D. carinata was more pronounced, and only at higher concentration of S. obliquus did that toxic effect abate. Our results indicated that green algae could greatly weaken the toxic effect of cyanobacteria.
