Studies on the improvement of the productivity of purse seine fishery-III - The characteristics on the motion with the flow velocity of model purse seine of the subjective power block and triplex during pursing - [PDF]
Journal of the Korean Society of Fisheries Technology, 2007 This fundamental studies on for the productivity improvement and laborsaving of purse seine fishery. Given the difficulty posed from the distortion of net shape caused by the external forces, such as tide, at the time of shooting and pursing, we set the 4 steps of 0, 2, 4 and 6cm/sec in flow velocity in the flume tank for the experiment in order to ...

NIPPON SUISAN GAKKAISHI, 1966 The experiments were carried out using model nets of different construction. The effect of time, from the laying of the net till the start of pursing (waiting time), and that of the direction of current on the working depth were observed. The results are summarized as follows: 1) The bottom margin of the net achieved maximum working depth at the 4/10 ...

Conditions for stability of the “vessel-purse seine” system during purse seining
IOP Conference Series: Earth and Environmental Science, 2021 Abstract In the process of tightening the rings of the lower seine line, significant forces of hydrodynamic resistance of the netting can capsize the vessel or pull it into the encircled seine area. There is a risk of damage to the propeller-rudder system of the vessel. The list and trim of a fishing vessel can occur.
