摘　　要：镁在大量的细胞生化反应中扮演着重要角色,它参与生物体内所有的能量代谢,催化或激活300多种酶体系。本文综述了鱼类镁的缺乏症、镁在鱼体内的吸收和代谢以及镁对鱼类生长、体组成、脂肪代谢、免疫、渗透调节等方面的影响,并阐述了镁与其他营养素的相互关系,介绍了鱼类对镁的利用率以及镁需要量的研究概况,对镁的营养生理机制做了简单探讨,旨在为全面认识镁对鱼类的营养和鱼类饲料中镁的科学应用提供理论参考。Magnesium is regarded as an important cation in cell biochemical reaction.It takes an important role in all of the energy metabolism,and catalyses or activates more than 300 kinds of enzymatic system.Advances in magnesium nutritional researches for fish were reviewed in this paper,including magnesium deficiency,absorption and metabolism,effects of magnesium on growth,nutrient composition,fat metabolism,immunity and osmoregulation in fish,magnesium-nutrient interactions,the bioavailability and requirement of dietary magnesium for fish,as well as the mechanisms of magnesium nutritional physiology,in order to supply references for a comprehensive view of magnesium in fish nutrition,advanced researches for future and scientific application of magnesium in fish feed.
