| 英文摘要 | Information on the dietary composition and food preferences of the giant jellyfish Nemopilema nomurai is important for understanding the trophic drivers of jellyfish outbreaks and their ecological consequences. We used fatty acid (FA) and stable isotope (SI) biomarkers to analyze the diet of N. nomurai from the Yellow Sea in August 2016. N. nomurai was found at all sampling stations, with abundances ranging from 59 inds./km(2) to 1 651 inds./km(2). There were no significant differences between large (>80 cm in diameter) and small (20-30 cm in diameter) medusae, either in FA compositions or in SI values, which suggests that large and small jellyfish have the same food composition and similar trophic levels. Compared to other Zooplanktons, the relatively high levels of C20:4n-6 in total FAs (similar to 12%) indicates that organic detritus contributes considerably to the food composition of the jellyfish. The mixed model Stable Isotope Analysis in R (SIAR) revealed that N. nomurai tended to prey on smaller organisms (<1 000 mu m in diameter) which comprised about 70% of its diet. This means the N. nomurai blooms will put high feeding pressure on the small plankton. The similar SI values and FA composition indicates that krill may share the same food resources with N. nomurai, which suggests that the jellyfish blooms may affect krill populations as a result of food competition. |
