| Abstract: | According to the analysis of the relationship between the hanging ratio and netting expenditure and sinking speed of foot line,and in combination with purse seine production practice in our country,a reasonable reference range and selection method of horizon hanging ratios between upper and lower edges of main part purse seine are proposed in this paper. Meanwhile,the selection reference ranges of horizon hanging ratios of upper strip,lower strip,wedge netting or side strip are also raised by means of the comprehensive analysis to the statistical data of the hanging ratio of China. The above-mentioned reference range and selection method of horizon hanging ratio will be of great value to the design of purse seine fishing nets in order to save the amount of netting used,reducing the fishing net costs,increasing the sinking speed of foot line and so on. |
