摘要: We studied in the laboratory the population growth rates of four cladocerans fed both with decomposed Microcystis aeruginosa and with a mixture of fresh colonial M. aeruginosa and Scenedesmus obliquus. The neonates of Diqphanosoma brachyurum and Daphnia carinata were able to develop into adults when they were fed with <64mum decomposed M. aeruginosa, while those of Moina micrura could not use decomposed M. aeruginosa. The population growth rate of the largest species, D. carinata, was less affected by the presence of fresh colonial M. aeruginosa than the other three species. D. carinata obtained the highest growth rate at a biomass level of 10 mg L-1 fresh colonial M. aeruginosa, indicating that, to some extent, it can use colonial M. aeruginosa at a size range of 64-112mum. The population growth rate of M. micrura was negatively correlated with fresh colonial M. aeruginosa within a range of 10-100 mg L-1. The population growth rates of D. brachyurum and Ceriodaphnia cornuta were remarkably decreased by fresh colonial M. aeruginosa, although no significant difference was found within the M. aeruginosa biomass range of 10-100 mg L-1 for either cladoceran. At a biomass level of 50 mg L-1 M. aeruginosa, the population growth rates of the four cladocerans positively correlated with S. obliquus biomass within a range of 0.1-5.0 mg L-1. Our results indicate that the zooplankton community under bloom condition is shaped by the quantity of both M. aeruginosa and other edible algae.
