英文摘要	This study evaluates the size-dependent predation of fish larvae by jellyfish, exemplified with flounder paralichthys olivaceus and moon jellyfish aurelia aurita under laboratory conditions. the effects of some environmental factors on the size-dependent predation were also investigated. the results indicate that the predation rate increased with larval development, until the larvae had developed the ability to actively avoid predation at approximately 11-day post-hatching and decreased thereafter. this suggests a size-dependent predation on the fish larvae. water temperature and predator size significantly affected the predation rate of the medusae on the fish larvae, but the temperature and size effects were markedly reduced as the larvae reached post-larval stage. these findings suggest that water temperature and jellyfish size interacted with the ontogenetic development of the fish larvae to affect the predation rates. the presence of alternative prey artemia salina, could alleviate the predation rate on the fish larvae, whereas light conditions showed no effects on the predation rate. due to their overlaps in spatial and temporal distributions along the north chinese coast, jellyfish are likely to prey upon flounder larvae and thus affect the recruitment of the wild fish populations.
