摘　　要：The scyphozoan Aurelia aurita （Linnaeus） sp. 1., is a cosmopolitan species-complex which blooms seasonally in a variety of coastal and shelf sea environments around the world. The effects of different microalgal species on the growth of newly-released Aurelia sp. 1 ephyrae were studied under laboratory conditions. We fed ephyrae with four different microalgal species （diatom, autotrophic dinoflagellate, heterotrophic dinoflagellate, and chlorophyta） plus A rtemia nauplii for 12-24 d at 18℃. Results showed that the growth rate diverged significantly for Artemia nauplii compared to other food types. In addition, there was no sig- nificant variation between the growth rates for Skeletonema costatum and Prorocentrum donghaiense, and no significant variation was found in the growth rates for N. scintillans and P. subcordiformis. Artemia nauplii could support the energy requirement for the newly-released ephyrae to develop to meduase, and the ephyrae with Artemia nauplii showed a significant average growth rate of 25.85% d-1. Newly-released ephyrae could grow slightly with some species of microalgae in the earliest development stage. Chain diatom Skeletonema costatum and autotrophic dinoflagellate Prorocentrum donghaiense, could not support the growth of the ephyrae, while heterotrophic dinoflagellate Noctiluca scintillans and chlorophyta Platymonas subcordiformis could support the growth of the ephyrae. However, none of the ephyrae fed with the tested phytoplankton could mature to medusae.The scyphozoan Aurelia aurita(Linnaeus) sp. l., is a cosmopolitan species-complex which blooms seasonally in a variety of coastal and shelf sea environments around the world.
