| 内容記述 | In order to investigate the entanglement of purse-seines, a series of model experiments, based on Tauti's principle was made. A typical two-boat sardine and pilchard purse-seine operating in about 100 fathoms in the deep water of Hyuga-Nada, Japan, was chosen as the object for this model experiment. The whole dimension was reduced to 1/250 of the full scale. With the supposition that the entanglement may be caused by fluttered webbing around the purse line during the pursing, the sinking behaviour of the bottom margin of the net and the change of tension in the purse line in the course of pursing were investigated experimentally. It was found that in the early stage of the fishing operations there was a large amount of loose webbing around the purse line and the tension of the purse line increased sharply. The gear seemed liable to entanglement during the early stages of the operation, and it was concluded that means of sinking the leadline more quickly should be found. | |||||||||
