Investigations were made on the vessels fishing with long-line or floating-gill-nets concerning the above mentioned 'carrying of an additional light', with the questionnaries answered by 186 fishing vessels. According to those answers it was ascertained that the number of the vessels carrying the light was no more than 4.8% of the whole ; the reason of which was brought under researching investigations and the following items were clarified: -(1) During the fishing the direction of the gear is under perpetual changes, which makes it difficult to keep the light carried right to the direction. (2) Even when the light is kept right to the direction, it is not always easy to discern the direction of the gear by the guidance of the light. (3) The small sized fishing vessels are generally low masted, and illuminated with high-powered working lamps ; which makes it extremely difficult to discriminate the carried light from others. (4) On the contrary, there is the possibility that the carried light may be misunderstood, which may incur some dangerous accidents.
