渔业生产的对象是生活在水域中的动植物,渔业生产和科学实验要求对对象进行直接的水下观察。随着科学技术的发展日益广泛地采用了各种新的水下观察技术。水下电视即时可见,能在较低的光强下工作是水下电视系统的根本优点。磁带录象和再现装置更使水下电视成为水下观察研究的重要手段。目前水下电视已广泛地应用于各个领域,如海底石油开采、海洋锰团块的开发、水下管线、水下建筑的监视等。在渔业方面水下电视的应用最早的报导是1954年,日本东京水产大学从国外引进了水下电视在静冈县宇佐美湾进行的试验。一、国外水下电视在渔业中的应用 1.海洋动、植物生态和生态系研究中的应用。应用水下电视进行种群调查、研究 Fisheries are produced for animals and plants living in the water and fisheries production and scientific experiments require direct underwater observation of the target. With the development of science and technology, a variety of new underwater observation techniques have been increasingly adopted. Submarine television can be seen immediately, to work at a lower light intensity underwater television system is the fundamental advantage. Tape video and playback devices make underwater television more important for underwater observational research. At present underwater television has been widely used in various fields, such as submarine oil exploration, the development of marine manganese clumps, underwater pipeline, underwater construction monitoring. The earliest application of underwater television in fisheries was reported in 1954 when Japan’s Tokyo Fisheries University introduced underwater television’s test at the Utsumi Bay, Shizuoka Prefecture. First, the application of foreign underwater television in fisheries 1. Oceanography, plant ecology and ecosystem applications. Application of underwater television population survey, research
