In accordance with the invention, a fishhook includes a shank portion and a curved hook portion. The hook portion includes a point at its end remote from the shank, and defines a cavity adjacent the point. The opening of the cavity faces the shank. A movable barb is affixed for movement between a retracted position, in which the barb is substantially contained within the cavity, and an extended position, in which at least a portion of the barb protrudes. A spring arrangement urges the barb toward its protruding position. In one embodiment of the invention, a hinge pin is affixed to the hook portion adjacent the point, and transfixes the movable barb for rotary motion between the retracted and protruding positions. The spring arrangement is a leaf spring affixed to an edge of the barb. A stop is provided to prevent excessive rotary motion.
