| 摘要: |
| 1950年以前有关报道渤海浮游动物的文献很少。1958~1959年的全国海洋普查取得了大量的浮游动物资料(中华人民共和国科学技术委员会海洋组海洋综合调查办公室编，1964)。1982~1984年，在一年多的时间里，先后进行了每月一次的浮游动物调查(白雪娥等，1991)。1984年8月，11月和1985年2月，5月，有4个季度的浮游动物调查(孟凡等，1993)。除此之外，一些专家就渤海部分海区的浮游动物进行了研究(肖贻昌，1988；钟贻诚等，1984)。作为“渤海生态系统动力学和生物资源持续利用”研究的一部分，本文报道1998年秋季和1999年春季渤海浮游动物群落的调查结果，为渤海生态系统研究积累资料。 |

| Abstract: |
| The central and southern parts of the Bohai Sea was investigated by the authors during a cruise by the R. V. Dongfanghong No. 2 in September and October, 1998 and April and May, 1999. Except for larval zooplankton, 53 zooplankton species were identified. Labidocera euchaeta, and Sagitta crassa dominated in autumn, 1998. While Calanus sinicus, Centropages mcmurrichi dominated in spring, 1999. Copepods accounted for 32%-83% of the total mesozooplankton abundance in the 4 investigations. S. crassa accounted for 33%-38% of the total abundance in autumn. A medusa, Rathdea Octopunctata, occurred in abundance at some stations in spring, 1999. The maximum abundance of C. sinicus was 249 and 1442 ind./m3 in autumn and spring respectively. The maximum abundance of L. euchaeta and S. crassa in autumn was 494 and 283 ind./m3, respectively. In the spring, the abundance of C. mcmurrichi reached its maximum of 2605 ind./m3. The biomass (wet weight in mg/m3) of zooplankton ranged from 26-488 ind./m3 (143 ind./m3 on average) in Sep 1998, 35-477 ind./m3 (167 ind./m3 on average at 30 stations) in Oct 1998, 36-1257 ind./m3 (293 ind./m3 on average) in Apr 1999 and 88~916 ind./m3 (321 ind./m3,on average) in May 1999. |
