脂肪酸在鱼类营养中起着重要的作用，脂肪酸作为能源物质为鱼类的生长发育等各项活动提供能量，并协助脂溶性维生素的吸收和体内运输。不同鱼类因其生活环境不同，对必需脂肪酸的需求种类也不同。由于不同脂肪水平与不同脂肪酸来源的饲料因其脂肪酸含量或脂肪酸组成不同，不同鱼类或鱼类的不同生长阶段对脂肪源的利用也不同，那么饲料的脂肪水平或脂肪酸组成不同就对鱼类的生长、脂代谢及免疫性能产生一定的影响作用。必需脂肪酸作为鱼类重要的脂肪酸营养物质同样影响鱼类的生长、脂代谢及免疫性能。本文从脂肪酸营养对鱼类生长、脂代谢及免疫性能的影响等方面进行综述，并对今后的研究重点进行了展望。’

The fatty acid plays an important role in the fish nutrition; fatty acid, as an energy material, provides energy for the fish such as the growth and development of various activities, and assists in the fat-soluble vitamins in the absorption and transportation. Different fishes have different life environment, so that they need different essential fatty acid. Due to the different fat levels and different lipid sources of feed whose fatty acid contents or compositions are different, different fish or the different growth stages of fish also have different utilization of lipid. So the feed＇ s different fat levels or composition of fatty acid would affect the growth, lipid metabolism and immune performance of the fish. The essential fatty acids as an important lipid nutrition can also affect the growth, lipid metabolism and immune performance offish. This article reviews the effects of fatty acid nutrition on the growth, lipid metabolism and immune performance offish.
