摘要	Nutrient imbalance-a mismatch in nutrient ratios between the available food supply and the demands of consumers-has the potential to be transported up food chains, exposing higher trophic-level organisms to nutrient limitations. We performed experiments to estimate the tolerance of jellyfish ephyrae (Aurelia sp. 1) and fish larvae (Paralichthys olivaceus) to nutrient limitations, and analyzed their growth, survival, and elemental homeostasis. As the primary consumer, rotifers Brachionus plicatilis exhibited the lowest amino acid content but the highest fatty acid content in a P-limited treatment. Among the secondary consumers, nutrient limitations (especially P limitation) had significantly negative effects on the growth of P. olivaceus larvae, but no significantly negative effects on Aurelia sp. 1 ephyrae. The 10th percentile mortality time of Aurelia sp. 1 ephyrae was much longer than that of P. olivaceus larvae. In terms of elemental homeostasis, Aurelia sp. 1 ephyrae showed a greater ability to maintain constant chemical composition in their bodies than P. olivaceus larvae. Additionally, growth and survival of P. olivaceus larvae could be negatively affected by the reduction of amino acid contents (but not fatty acids) in their nutrient-limited food. These results indicate that Aurelia sp. 1 ephyrae could be more competitive than P. olivaceus larvae with respect to tolerance of nutrient limitations, and, thus, elemental imbalances may favor increases in jellyfish in some eutrophication regions.
