英文摘要	The anthropogenic aggravation of global climate change is an important environmental problem, and the imbalance between pCO_2 and dissolved oxygen in the ocean and eutrophication have aggravated the acidification and hypoxia of many coastal ecosystems. Rhopilema esculentum is one of the most important fishery resources in China, which has edible value and potential medicinal value. In this study, the physiological responses of the ephyrae of R. esculentum under the stress of ocean acidification and hypoxia and their circadian rhythm changes were evaluated: the ephyrae was exposed to two levels of pH(acidified pH 7.6;normal pH 8.1)and two dissolved oxygen(DO)levels(hypoxia 2 mg·L~(-1);normoxic 7 mg·L~(-1))for 7 days. The stress factors remained constant or fluctuating, and the bell diameter, pulsation rates and activities of acid-base balance, immunity and antioxidation related enzymes of ephyrae were measured. The results showed that the ocean acidification and hypoxia affected the physiological metabolism, growth and development of R. esculentum ephyrae in different degrees, and there was a partial antagonism between acidification and hypoxia. The effects of diurnal fluctuating exposure mode to R. esculentum ephyrae was more harmful than that of constant exposure mode.
