• In Tanabe bay, the lift net fishery has been operating to catch Anchovy, Round herring, Mackerel and Horse mackerel with two kinds of attracting fish lamps, setting on the board and under water. In 1952, the fishing ground was distributed in area 3miles×13miles, fishingboat had been numerated to 57 in there and the fishing season was from April to August. Each boat had been operating under the same conditions for this fishery. In these studies, the cause for difference of the amount of catch among each boat is investigated and the results obtained are shown as follows. Swimming area of fish, which means the parts of higher density of fish, is limited to a narrow scope 1/8 area of the around and in this area a numerous boat are operating more frequently than the others. Therefore, it is clear that the boats gained a large amount of catch have been fishing more times in this area compared with other boats. Furthermore, it is shown as the illumination power of two lamps used for this fishery is too strongly for scale of this net, many fish are gathered to out-side of net rather to inside.
