辽宁沿岸海洋底栖钩虾类的种类组成与分布

Composition and distribution of the species of Gammaridea in the Liaoning coast

钩虾类不仅是底栖生物群落的重要组成部分，也是近年来沉积物环境质量研究中主要选用的受试生物。本文根据１９７９～１９９６年在辽宁沿岸采集的底栖钩虾类标本，首次报道了辽宁沿岸海洋底栖钩虾类的种类组成和生态分布。共报道２９种，分别隶属于１０科２２属，其中有１种为中国新记录。该研究结果将对我国海洋底栖钩虾类的区系研究和沉积物毒性检验受试生物的选择和采集提供一定帮助。

Amphipods are not only important part in the composition of organisms in benthic communicity, but some of them also were used as mainly testing organisms in the study on the sediment environmental quality in recent years. The paper first present the composition and distribution of the species of Gammaridea(Crustacea: Amphipoda) in the Liaoning coast(Bohai and Yellow Sea). The speciements used for the study were collected in the Liaoning coast during 1979～1996. Twenty nine species belong to 10 families and 22 genera of marine benthic Gammaridea were identified. Of these, 1 species were recorded for the first time in Chinese waters. The results may be helpful to understand the fauna of Gammaridea in Chinese sea and choice adaptive testing amphipods for sediment toxicity test.
