The current study exploredAurelia auritaandRhopilema esculent umconsumption by silver pomfret juveniles, as well as their prey selection between the two jellyfish species. Silver pomfret juveniles weighing 1±0.1 g actively preyed on both the species. Their dailyA. auritaconsumption was 11.6 times their own body weights regardless of the size ofA. auritamedusae. Their dailyR. esculent umconsumption was 13, 9.1, 5, and 4.1 times their own body weights when theR. esculentummedusae were 10, 20, 30, and 40 mm in bell diameter, respectively. The survival rates of theR. esculent umwere higher than those of theA. aurita. When theR. esculent ummedusae were more than 30 mm in bell diameter, their survival rate exceeded 92%. Silver pomfrets serve as a type of potential predators onA. auritain coastal waters, and they have little influence onR. esculent umwith a size exceeding 30 mm. Besides,A. auritamay be able to be used as fish prey in silver pomfret artificial breeding.
