| 摘 要： | 于 1 995年 6月— 1 997年 1 2月 ,对徐家河水库枝角类优势种群的密度和近太湖新银鱼 (Neosalanxpseudotaihuensis)的生物量 (单位努力量渔获量 )进行了初步调查 ,以期研究银鱼与浮游动物的关系。结果表明 ,在 1 995年银鱼的生物量较高时 ,透明薄皮 (Leptodorakindti)、盔形 (Daphniagaleata)和模糊秀体 (Diaphanosomadubia)等大型枝角类的密度较低 ;在 1 997年银鱼的生物量较低时 ,这三种枝角类的密度则较高。而象鼻 (Bosminaspp )这样的小型枝角类恰恰相反 ,当银鱼的生物量较高时 ,其密度较高 ;反之 ,其密度较低。表明银鱼可以对枝角类产生显著的影响 |

| Abstract: | In order to study the interactions between icefishes and zooplankton, investigations into the densities of the dominant cladocerans and CPUE of the icefish Neosalanx pseudotaihuensis in Xujiahe Reservoir were undertaken during the period from June 1995 to December 1997.Results show that the numbers of large cladocerans Leptodora kindti, Daphnia galeata and Diaphanosoma dubia were the lowest in 1995 when the icefish was most abundant, while they were more abundant in 1997 when the icefish was low in CPUE.However,Bosmina spp.were numerous in 1995 when the icefish was high in biomass.This study suggests that the icefish could exert a significant impact on zooplankton community. |
