水生动物肌醇营养研究进展

摘要

Myo-inositol is an essential nutrient for most aquatic animals to stay healthy and promote growing, and it plays an important role in the synthesis of the membrance phospholipids, neurotransmission, and liver lipid transfer. Dietary myo-inositol deficiency in aquatic animals leads to symptoms such as a sharp decrease on the rate of growth, surface hyperemia, fin erosion, black body color, fatty liver disease. This study reviewed the myo-inositol physicochemical properties and its physiological function, requirement and influencing factors in aquatic nutrition, meanwhile, it described the sources of myo-inositol and detection methods, and proposed prospects for further research and application direction of myo-inositol in aquatic nutrition.%肌醇是大多数水生动物保持健康、促进生长发育必需的营养素，它在细胞膜磷脂合成、神经递质传递和肝脏脂质转运等方面发挥重要作用。饲料中肌醇缺乏导致水生动物生长不良、体表充血、鳍条糜烂、体色发黑、脂肪肝等症状。本文综述了肌醇的理化性质，肌醇在水生动物营养中营养生理作用、需要量及影响因素等，同时还介绍了肌醇的来源和测定方法，并展望了肌醇在水生动物营养中进一步的研究和应用方向。
