To solve the problem in which the work efficiency for peeling and removing barnacles and the like adhering to a fishery float is poor, hindering proper operation of the fishery float.SOLUTION: In a fishery float 10 composed of a hollow spherical portion and annular ear portions, if the surface between antipodal points of the hollow spherical portion 11 (excluding the region in which the ear portions are formed) is formed as an uneven surface 14 in which a shape meandering with a predetermined amplitude and period in the meridian direction continuously circles in the latitudinal direction, then the uneven surface 14 becomes a growth-inhibiting factor for barnacles and weakens their adhesive strength. A blade 32 having comb-shaped cutting edges is attached to a vibration-driven tool 30, and by pressing and vibrating the comb-shaped cutting edges in the circumferential direction in a state in which the comb-shaped cutting edges are fitted in the recesses of the uneven surface 14 of the fishery float 10, surface deposits 40 such as barnacles adhering to the fishery float 10 can be efficiently peeled and removed.SELECTED DRAWING: Figure 4
