长臂虾中沼虾属已有几个品种被用作人工杂交的人工授精试验。试验用的精荚大多是人工直接从输精管中挤出来的新鲜的粘性精荚,而保存的长臂虾精荚,迄今尚未充分应用于人工授精。这是因为射出后的长臂虾精荚裸露于水中,很快失去粘性。作者在本项研究中开发了一种用保存的罗氏沼虾精荚进行人工授精的简单技术。材料与方法成熟的罗氏沼虾雌雄个体被分别饲养在水温25～29℃的淡水水族箱中,刚经历生殖蜕壳的一只雌虾,被引入养有一只雄虾的水 Several species of marsh shrimp have been used as artificial insemination artificial insemination test. Most of the experimental pods are fresh, viscous, fine pods that are artificially extruded directly from the vas deferens. The preserved long-legged prawn pods have not yet been fully used in artificial insemination. This is because the long-armed shrimp pod after injection is exposed to water and quickly loses its viscosity. In this study, the authors developed a simple technique for artificial insemination using conserved Macrobrachium rosenbergii. MATERIALS AND METHODS Mature male and female individuals of M. rosenbergii were respectively housed in a freshwater aquarium at 25-29 ° C. A female who had just undergone reproductive molting was introduced into the water containing a male shrimp
