南海东北部大陆架边缘水域的虾类资源及其开发前景

<正> 对南海大陆架边缘水域虾类资源的研究,至今还很少。其原因一方面因该海区的水深深度较大,拖网设备要求较高;另一方面在人们的概念上往往认为随着海洋水深深度增大,虾类分布密度减低,可供开发利用的资源也越来越少。因此,人们的注意力都放在沿岸海区虾类资源的利用和管理。自1978～1982年间,南海水产研究所在南海北部大陆架边缘区和大陆斜坡区发现深海虾类资源后,对深水海区的渔业资源有了新的认识。南海北部大陆斜坡的虾类资源已在80年代初开始开发,但大陆架边缘区的虾类资源的开发问题,仍然没有受到有关部门的重

The Resources of Shrimp in the Marginal Waters of Continental Shelf of the Northeastern Part of the South China Sea and Their Prospects for Exploitation

Based upon the investigation of bottom fishery resources in the mar-ginal waters of continental shelf of the northeastern part of the SouthChina Sea,the feasibility of utilization to the resources has been analy-zed.The dominant species such as Haliporoidaes sibogae,Heterocarpuswoodmasoni,Plesionika martin and Heterocarpus sibogae are concentratedand abundant in the narrow zone of 280-350m in depth with an area of1750 sq.miles,and it is estimated that the catchability amounts to 20000tons.
