摘　　要：在水和BSS激活剂的激活下,白点鲑(Salvelinus leucomaenis)精子的A、B级快速运动时间分别为34.83±2.15 s和36.70±3.26 s;精子寿命分别为120.26±5.75s和117.45±4.33s,激活比例高于98%,BSS的激活效果更好。在4℃和15℃条件下,白点鲑精子活力、激活比例和精子寿命与保存时间呈负相关性,保存1～2h以内,经保存的精子活力和精液质量较好,不影响人工授精效果。The sperm motility of Siberian char （Salvelinus leucomaenis） was observed in the semen activated by activators water or BSS. The results showed that the rapid movement time of A and B degrees was 34.83±2.15 s and 36.70±3.26 s, respeetively. The life span of the spermatozoa was shown to be 120.26±5.75s when the semen activated by water and 117.45±4.33s when activated by BSS, with activating ratio of more than 98%. BSS was found to have a better performance on activating than water. There was a nega- tive correlation between sperm motility, activating ratio, life span and storage time at the water temperature of 4℃ and 15℃. The sperm preserved in 1 -2 h had better motility and quality without significant effect on artificial insemination.
