英文摘要Environmental factors such as temperature and food type affect the rate of asexual reproduction of jellyfish at the polyp stage. combinations of three temperatures (10, 15, and 20a degrees c) and four food treatments (prorocentrum donghaiense, skeletonema costatum, artemia sp. nauplii, and no food) were established to examine the asexual reproduction strategy of aurelia sp.1. the results allowed us to reject two null hypotheses: no effect of temperature and no effect of food. a change from 20 to 15 or 10a degrees c induced polyps to release ephyrae when food was present, while polyps without food did not strobilate. polyps with artemia sp. nauplii as prey produced more polyps through buds and podocysts, as well as more ephyrae through strobilation. at 20a degrees c, the mortality rates of polyps exceeded 50%, except for those served by artemia sp. nauplii. the number of polyps increased rapidly with artemia sp. nauplii as prey. we conclude that when animal prey is limited, plants can serve as a nutrient source and satisfy the energy requirements for polyps at lower temperatures (10 or 15a degrees c). phytoplankton cannot provide adequate nutrition to polyps at higher temperature (20a degrees). abundant animal prey and suitable temperatures are essential conditions for polyps to strobilate and release ephyrae, leading to jellyfish blooms.
