| 有关东海的虾类，刘瑞玉(1959，1963，1964)、董聿茂(1959，1980，1986)等已做过大量的调查研究。近10多年来，由于东海传统的主要经济鱼类资源衰退，捕食虾类的鱼类减少，因此，使虾类生存空间扩大，这有利于虾类资源的繁衍生长，使虾类资源发生量增多，数量增长较快。东海区三省一市近几年虾类产量达到80×104~90×104t，其中浙江省为60×104~70×104t，拖虾作业已成为东海区一大作业方式，对促进海洋捕捞业的发展起重要作用。20世纪80年代中后期，我们开展了东海虾类资源开发调查，尔后又继续与拖虾生产船相结合进行监测调查，积累了一些资料，本文就东海虾类生态群落结构与区系特征进行探讨。 |

| Abstract: |
| 1. Ecological colony
The East China Sea has three water systems of different properties eurythermal and low-salinity water along the coastal line, high-temperature and high-salinity water in the east, low-temperature and high salinity water coming from the southern Yellow Sea bottom layer and so is rich in shrimp resource of different ecological species. Based on the ecological species inhabiting certain temperature and salinity range layers, shrimps inhabiting the ECS continental shelf can be classified into three types.
2. Faunal Characteristics
As to the characteristics of shrimp fauna in the East China Sea and from the perspective of its composition, affected by the high-salinity water, tropical and warm species dominate; in the coastal water areas, affected by the land climate and freshwater from rivers, the shrimp composition was the same as that in the Yellow Sea and Bohai Sea; in the northern part affected by the lower layer cold water from the Yellow Sea, there were a few cold water species. As compared with adjacent waters, 73% of the species are commonly found in the South China Sea; 62% in Japan; 44% in South Asia; 33% in India; 29% and 20% in the Yellow Sea and Bohai Sea respectively. Hence, the shrimp fauna in East China Sea belongs to the west Pacific fauna. |
