Abstract A guard for a barbed fish hook comprises a length of clear vinyl tubing having an internal diameter slightly less than the maximum cross sectional dimension of the hook at the point of the barb. The ends of the tubing are cut off at an angle of about 35* and slits are provided in opposite sides of the end portion midway between the high and low parts of the inclined end surface.
