135马力以上的拖网渔船大多在100米等深线内外进行拖网捕捞作业,那么拖网渔船作业海区到港口的距离及停港装卸时间及航速等之间有着密切的联系,拖网渔船无论是出航或者返航都存在着最佳航速问题。另外,各航次间停港装卸时间的长短对拖网渔船的经济效益有很重要的影响。本文从经济航速和停港时间两个方面探讨了拖网渔船的经济性,谨供水产科技工作者及海洋捕捞生产单位参考。
Trawlers above 135 horsepower are trawling operations both inside and outside the isthmus of 100 meters, so there is a close relationship between the trawler working sea area to the port and the port loading and unloading time and speed. Trawlers, whether on the voyage or the return There is the best speed problem. In addition, the length of port loading and unloading time between various voyages has an important impact on the economic benefits of trawlers. This article discusses the economic efficiency of trawlers from two aspects of economic speed and stopping time. It is for the reference of aquatic science and technology workers and marine fishing production units.
