A fishhook includes a rigid shank having an articulated hook portion comprising a plurality of pivotally connected segments attached thereto with a barb element at the free end of the hook portion. A bore through the shank communicates with bores in the segments and these serve to house a flexible cable having its distal portion affixed in the area adjacent the barb element. When relaxed, the cable allows the hook portion segments to assume an extended position substantially axially aligned with the shank and in this position a space is formed between the juxtaposed faces of the adjacent segments whereby, subsequent tightening or retraction of the cable pivotally displaces the segments upwardly and rearwardly until the juxtaposed faces abut one another to form a rigid curved hook portion. The barb element may be rigid with respect to the forwardmost segment or alternatively may comprise a displaceable element pivotally attached to the segment and likewise operable upon relaxation and retraction of the cable.
