围网捕捞是海洋渔业中的主要作业方式之一。自从1954年美国发明了围网动力滑车之后,世界围网作业有了较大的发展,特别是六十年代以来,世界主要渔业国家大力发展围网作业,至七十年代,围网捕捞产量约占海洋总捕捞产量的三分之一。我国渔业有着几千年历史,是发展围网作业较早的国家。但近百年来围网作业发展比较缓慢,围网捕捞技术已落后于渔业发达的日本、美国和挪威等国家。 Purse seine fishing is one of the main operations in marine fisheries. Since the invention of the fencing power block in the United States in 1954, there has been a great development in the operation of the world fencing. In particular, since the 1960s, the major fishing nations in the world have been vigorously developing their fencing operations. By the seventies, seine fishing output was about Accounting for one third of the total ocean fishing output. China’s fishery has a history of thousands of years and is an early country in the development of the seine network. However, the development of seine operations in the past 100 years has been relatively slow. The seine fishing technology has lagged behind the countries with developed fisheries in Japan, the United States and Norway.
