东海陆架区浮游端足类𧊕亚目的初步报告

关于东海陆架区的浮游端足类??亚目( Amphipoda: Hyperiidea),过去了解很少,迄今仅郑重、郑执中等(1965)报道细长脚?? ( Themisto gracilipes )是黄海主要浮游动物之一。陈瑞祥(1978)报道了采自江苏、浙江近岸水域和福建东南近岸水域数种浮游端足类。 Stephensen(1925)曾报道过Amphithyrus bispinosus分布于香港一上海之间水域。入江春彦(1957)报道了日本五岛列岛一香港之间水域数种浮游端足类。本文根据1976年调查的资料,对东海大陆浮游端足类??亚目的种类组成和数量分布进行了初步报告。通过这次调查,对调查区的浮游端足类有了初步了解,为今后进一步研究东海浮游端足类的分类与生态工作提供了基本资料。但由于调查时间较短、范围较小,资料仍有一定局限性。

A PRELIMINARY REPORT ON THE HYPERIDEA AMPHIPODS FROM THE CONTINENTAL SHELF OF THE EAST CHINA SEA

No detailed investigation has, hitherto, been made of the Hyperiidea amphipods of China, and there is no record ever taken with the materials of this area.The materials used in this report was based on the Oceanological exploration made by the Institute of Oceanology, Academia Sinica, during the months of June-July, August-September, 1976, between 26.5°-31.5°N 122°-127.5°E. in the continental shelf of the East China Sea.The present collection contains 39 species, belonging to 26 genera and 11 families.The present report is mainly coneerned with the distribution and variation of species population of Hyperiid amphipods. Hydrological conditions; especially, temperature, appear to be one of the chief factors affecting their distribution and variation of species population of Hyperiidea amphipods.
