| 摘要: |
| 中华哲水蚤(Calanus sinicus Brodsky)是我国近海的优势桡足类。它的数量大，分布广。特别在冬、春季，在我国近海浮游动物中，占有相当大的比例；同时它的个体也较大，是滤食性种类。因其在海洋生态系统的物质循环和能量流动中，起着相当的作用，所以被国家自然科学基金重大项目-“东、黄海生态系统动力学与生物资源可持续利用”课题定为浮游动物的关键种之一。
作者根据以往历史资料(方金钏，1979；朱长寿，1997；朱长寿等，1991、1999；林玉辉等，1988；林元烧等，1984；李少菁，1963；陈清潮，1964；福建省海岸带和海凃综合调查领导小组，1990；福建海洋研究所，1988；Tan，1970)和多年来的研究结果(黄加祺等，1984，1986a、b、c，1989，1991a、b，1997a、b)，对中华哲水蚤在不同水域的分布，与温、盐度关系及繁殖进行了探讨，并提出见解，为本项目子课题提供了历史资料。 |

| Abstract: |
| Based on the history materials of Calanus sinicus in Taiwan Strait and its Adjacent sea areas, the distribution and reproduction of C.sinicus were researched. The results show that C.sinicus distributed all year round, in north and middle parts of Taiwan Strait, but seasonally in south part of Taiwan Strait and Xiamen Harbour. The number of C.sinicus in these regions attainted its great maximum in spring. Secondary maximum in winter, and minimum in autumn even disappeared. The abundance of C.sinicus is more near shore than off shore, more in the north than in the south in horizontal distribution. C.sinicus distribute from bottom layers to surface layers, but its adults live in bottom layers in summer and in upper layers up 35m in winter. Diurnal vertical migration of C.sinicus is marked. There were three main breeding period (i.e. 3 generations) in Taiwan Strait and Xiamen harbour. The relative questions were discussed in this paper. |
