海洋开发与原子能和空间技术已并列为当代三大科学技术。直到六十年代未,各国在海洋开发方面所投入的力量远远低于其它二个方面,近二年来,这种情形正在发生明显的变化。尤其是苏美二国,争夺海洋日趋激烈。当前争夺最为激烈的海洋资源,就是海底石油和海洋水产。就海洋水产论,目前全世界每年的海洋捕鱼量约为七千万吨,现时每年以6—7%的增长量在增加,所以近年内海洋捕鱼量即可达到一亿吨。
Marine development and atomic energy and space technology have been listed as the three major contemporary science and technology. Until the 1960s, the power invested by various countries in marine development far outweighed that of the other two. This situation is undergoing significant changes in the past two years. Especially the Soviet Union and the United States, fighting for the increasingly fierce ocean. The most intense marine resources currently contested are the seabed oil and marine aquaculture. As far as marine aquaculture is concerned, at present, the world’s annual ocean fishing volume is about 70 million tons. At present, it is increasing by 6-7% each year. As a result, the volume of marine fishing in the world can reach 100 million tons in recent years.
