英文摘要：

UV radiation is known to affect aquatic primary producers and their grazers. However, little has been documented on its effects on zooplankton grazing. In this study, the authors investigated the effects of photosynthetically active radiation （PAR, 400–700 nm）, ultraviolet-A （UV-A, 320–400 nm） and ultraviolet-B （UV-B, 280–320 nm） radiation on grazing, mortality and lipids oxidation of the copepod Acartia pacifica collected from the Xiamen Bay. After 30 min of the exposures, the copepod was fed in darkness with the diatom Phaeodactylum tricornutum at two cell concentrations （2.5 × 10 4 and 2.5 × 10 5 cells/ml）. At the low cell concentration, the individuals pre-exposed to PAR （218.0 W/m 2 ）＋UV-A （48.2 W/m 2 ） or PAR＋UV-A＋UV-B （2.1 W/m 2 ） showed suppressed clearance and grazing activities compared with those receiving PAR alone, by 22.7% and 17.1% for clearance and by 22.6% and 5.5% for grazing rates, respectively. However, the suppression on clearance and grazing became indistinctive at the high food concentration. Exposures to UV-A and UV-B led to increased lipid oxidation and higher mortality, furthermore, the mortality linearly increased with enhanced oxidation of lipid.
