拖网网板性能与国内外应用研究进展

Research on performance and application of otter board at home and abroad

拖网网板是应用于拖网渔具以扩张网口的重要渔具构件,一直以来在海洋捕捞拖网作业中备受关注。基于文献计量分析方法,从时间序列、国家(地区)文献分布、研究热点等方面对拖网网板的研究状况进行文献计量及可视化分析,以了解国内外拖网网板研究应用方面的发展动态与研究焦点。此外,还针对影响网板性能的设计因素进行了分析论述,并根据网板性能的研究与试验方法,分析对比各种方法的特点及发展趋势。基于拖网渔业与装备技术的发展,结合网板性能的研究成果,提出网板应用研究的两个重要方向,即网板结构智能化调控技术与网板新材料应用技术,为拖网网板的性能与应用研究提供参考。

Otter board,as an important fishing gear component used in trawling to expand the net opening,has long been a concern in marine trawling operations.Based on bibliometric analysis,from the time series,national/regional document distribution,research hotspots,etc.,the literature metrology and visual analysis of the research status of otter board are carried out,so as to understand the development trend and research focus in research and application of otter board at home and abroad.In addition,the design factors that affect the performance of otter board are analyzed and discussed,and the characteristics and development trend of various methods are analyzed and compared according to the research and test methods of the performance of otter board.Based on the development of trawl fishery and equipment technology,combined with the research results of the performance of otter board,two important research directions for the otter board application are proposed,including the intelligent control technology of the otter board structure and the application technology of new materials in otter board,which provide reference for the performance and application research of the otter board.
