D-α-tocopherol acetate was supplemented to the basal(control) diet(65.14 mg kg–1 Ve) to obtain low and high levels of dietary Ve(244.60 mg kg–1, LVe; 721.60 mg kg–1, HVe). Compared with the control, sperm concentration was significantly increased in Ve-supplemented groups(LVe and HVe); while relative sperm volume and testis-somatic index were significantly increased in group HVe only. Sperm motility duration was significantly longer in group HVe than in the control, but no significant difference was observed in percent motility among groups. Sperm size, the uniformity of mitochondrial size, and the integrity of mitochondria cristae and plasma membrane were improved by dietary Ve, especially in HVe. The content of Ve in testis and liver as well as polyunsaturated fatty acids in sperm increased with dietary Ve. These results suggested that dietary Ve, especially at the high level(721.60 mg kg–1), significantly improved sperm concentration and motility duration and maintained normal sperm morphology of turbot. 关键词：精子质量维生素E 大菱鲆海水系统精子活力鱼脂肪酸含量持续时间
