在渔捞实践中,最近出现了加大拖网前部网目尺寸的趋势。因此,鱼类从网目逃出的问题,具有重大的意义。在文献中,这个问题报道得不多。为了查明鱼类在拖捕区和各种网目的身网附近的行动特点,以及确定鱼类从拖网网目逃出的数,1971—1974年渔捞实验设计专业局的工作人员,用“穆克松”号舷拖船和“海峡”号考察船,在不同的海区进行了一系列结合水下观察的试验工作。 In fishing practices, there has recently been a trend towards increasing the size of the trawl mesh at the front. Therefore, the problem of fish escaping from the net is of great significance. In the literature, there are not many reports on this issue. In order to identify the characteristics of fish operations in towing areas and various nets and to determine the number of fish that escaped from trawl nets, the staff of the Bureau of Fishing Experimental Design 1971-1974, The “Mukonsong” starboard tugboat and the “Strait” survey ship carried out a series of experiments combining underwater observation in different sea areas.
