最近五年来,世界海洋魚类資源的开发利用有很大的发展。漁业技术的发展也相当迅速,主要表現在三个方面:(1)利用超声波探索魚群;(2)改进远洋漁船的建造质量和建造速度;(3)改进冶冻技术和魚粉加工来提高漁获物的保藏与利用。近年来,据国际地球物理年計划进行的包括大洋底层角类的棲息环境、水团及浮游生物的分布等的全世界海洋的調查,大大地促进了
In the recent five years, there has been a great development in the exploitation and utilization of the world’s marine fish resources. Fisheries technology has also developed quite rapidly, mainly in three areas: (1) exploring fish stocks using ultrasound; (2) improving the quality and speed of construction of offshore fishing vessels; (3) improving smelting techniques and fishmeal processing to improve catch Material preservation and utilization. In recent years, surveys of the world’s oceans, including the habitat of the oceanic bottom horns, the distribution of water masses and plankton, carried out in accordance with the plan for the International Geophysical Year have greatly contributed to
