| 摘要: |
| 渤海是我国主要的海洋渔场之一,许多重要的鱼、虾类,如对虾等在此产卵、育幼、索饵。因此,研究作为饵料基础的环节动物多毛类的种类组成和数量分布,对渤海水产资源开发和经济动物的增、养殖都是有益的,并能为海洋环境硏究提供科学依据。关于渤海多毛类,前人已有很多报道。Fauvel(1933)报道了52种采自天津附近的多毛类,高哲生等(1959)也报道了渤海的一些多毛类,特别是吴宝铃和乌沙科夫(1963a,1963b)对渤海和黄海的多毛类进行过许多研究。最近,杨德渐和孙瑞平(1988)也报道了渤海的58种多毛类,但上述研究多限于区系分类方面的内容。本文主要根据1982年6月至1983年11月作者对渤海101个站(图1)底栖动物调查所获得的多毛类资料,对渤海多毛类的组成和数量分布进行探讨。 |

| Abstract: |
| This paper presents the results of study on polychaeta in the Bohai Sea. The materials for study were collected from 101 stations in June 1982-November 1983. The species composition and distributions of biomass and density are described and discussed. Of the 189 species recorded here, 115 species were collected during cruises, 74 species were recorded before. The distribution pattern of biomass was different from that of the density. Relative abundance of biomass was found in the Liaodong Bay, but relative abundance of density was found in the central area of the Bohai Sea. Low biomass and density were at the bottoms of the Liaodong Bay,Bohai Bay and Laizhou Bay. The average biomass of polychaeta was 1.99 g/㎡, about 8.7% of the total macrobenthic infauna. The average density of polychaeta was 96 ind /㎡，about 28.1% of the total macrobenthic infauna. |
