摘要: 在概述我国海域主要的资源生物及其开发现状的基础上,指出在70年代中期以前,随捕捞力量的增加,我国海洋总渔获量增长较快;但此后,尽管捕捞力量仍继续增加,总渔获量增长缓慢。作者认为,过度捕捞、污染以及其他不利的环境因素变化是导致总渔获量缓慢增长的主要原因。为合理利用资源,提高渔获量,应在加强海洋生态系研究的基础上,积极开发外海(包括远洋)资源,并着重发展海洋农牧化。

Abstract: After a brief introduction to the resource organisms in the China Sea, the author made aa overview on the history of exploitation of the organism resources. It was pointed out that the harvest yield had increased greatly with the increase of fishing intensity before the middle 1970's, however, since then, the amount of yield has decreased, in spite of still growing catch, intensity. The reasons causes for this discrepancy are over-exploitation of conventional fishery resources in the shallow shelf areas, pollution (mainly oil pollution in the coastal waters), and others, such as changes in environmental variables and red tides, among which the influence of the first is much greater than that of the other two. The following would be suggested for the better use of the resources:1)Make further study on marine ecosystems, which would greatly contribute to the rational exploitation and the management of the resources.2)Paff attention to resources off the coastal waters of the China Sea, in which the fishery stress on heavily exploited resources would be diminished and a stabilized fishery would be mainlained.3)Practise farming and ranching of the sea, especially multiplying some organisms in the lower trophic levels of marine food chain, which would also speed up recovery of the collapsed resources.
