Burinawa is a long rope equipped with many white painted wooden strips "buriki" and stone weights at regular intervals, and is the main device used in Buriami fishery. The moving performance of the Burinawa, used in the Buriami fishery for catching red sea bream <i>Pagrus major</i> and crimson sea bream <i>Evynnis japonica</i>, was measured by radar on board an anchored training ship. The shape, enclosing area and towing speed of the Burinawa were analyzed. The shape of the Burinawa was U-shaped, reduced in a similar manner with elapsed time, and was affected by the current. The enclosed area decreased almost exponentially. The towing speed of the Burinawa was 0.3kt at the middle and 0.5kt at both ends. The movement of the buriki and the tension of it were measured in a flume tank. Power spectra were estimated from the measurements. A dominant frequency of 1.3Hz was identified at only a flow speed of 0.3kt. From the results of the experiment, it was suggested that the Burinawa drive fish schools by visual and acoustic stimuli.
