通过对嘉陵江北碚江段黄颡鱼、大鳍越冬期间其胃、肠、肝胰脏、肌肉含脂量变化的研究 ,表明 :1 黄颡鱼、大鳍内脏各器官 (胃、肠、肝胰脏 )含脂量以越冬中期为最低 ,肌肉则相反 ,表现出越冬饥饿期间 ,该鱼主要利用内脏脂肪作为主要能量来源而不用大量肌肉脂肪 ;2 越冬期间 ,黄颡鱼、大鳍内脏各器官 (胃、肠、肝胰脏 )含脂量与含水量的变化有负相关关系存在 Through the study on the changes of fat content in the stomach, intestine, hepatopancreas and muscle during the winter over the section of Beibei River in the Jialing River Beilu fish, big fin pomfret, Liver and pancreas) had the lowest fat content in the middle of winter and the opposite in muscle. During overwintering and starvation, the fish mainly used visceral fat as the main source of energy instead of a large amount of muscle fat. During the winter, the catfish, The visceral organs (stomach, intestine, hepatopancreas) lipid content and water content changes have a negative correlation exists
