英文摘要：

On the basis of the hydrodynamic experimental results, the effects of Reynolds number, flow direction to the net, and net setting status on the drag coefficients of nodeless plane fishing net were studied. According to the experimental results, empirical formulas of the drag coefficient were achieved and their validity was verified through a specific experiment of net-weight system. The results are useful to the hydrodynamic calculation of fishing gears such as deep water sea cage, and so on.
