| 摘 要： | 作者观察了鲤、团头鲂精子在０（去离子水）－３００毫渗渗透压的Ｄ－半乳糖，Ｄ－葡萄糖和Ｄ－果糖溶液中的活动情况。结果表明，在这三种单糖溶液里，鲤、团头鲂精子活动的变化规律是一致的。精子快速运动和寿命的时间是以在Ｄ－半乳糖溶液中为最长。这两种鱼精子对这三种单糖的吸收、利用存在差别。

| Abstract: | Motility of spermatozoa from carp(Cyprinus carpio) and blunt snout bream(Megalobrma amblycephala Yih)are observed in D-galactose, D-glucose and D-fructose solutions containing thet 0～300mosmol L-1. The results show that change laws of spermatozoa activity for carp and blunt snout bream are in D-galactose solution. Absoption and utilization of the spermatozoa to me three monoses have difference. |
