There will be generated some adverse conditions in the process of acquculture farming with the continuous improvement of the intensive degree of modern aquaculture, such as crowding stress, hypoxia, and malnutrition, which will easily lead to oxidative stress. Se is an effective antioxidant, participating and playing an important role in the antioxidant defense system of fish. This paper reviews the physiological functions of selenoproteins in resisting oxidative stress in aquatic animals, the mechanisms of different forms of Se in anti-oxidative stress in aquatic animals and the harmful effects of lower and higher levels of Se in aquaculture. To summarize the application and research progress of Se in oxidative stress in aquatic animals and provide scientific references for its application in anti-oxidative stress in aquaculture.
随着现代水产养殖集约化程度的不断提高，在水产养殖过程中会产生一些不利条件，如拥挤应激、缺氧和营养不良，这些很容易导致氧化应激。硒是一种有效的抗氧化剂，参与鱼类的抗氧化防御系统并发挥重要作用。本文综述了硒蛋白在水生动物抗氧化应激中的生理功能、不同形式的硒在水生动物抗氧化应激中的作用机制以及水产养殖中硒含量过低和过高的有害影响。总结硒在水生动物氧化应激中的应用及研究进展，为其在水产养殖抗氧化应激中的应用提供科学参考。
