A fishhook adapted to prevent the escape of a hooked fish. In one embodiment, once a fish has been hooked in a conventional manner upon the conventional portion of the fishhook, the tension on the line causes a spearing member, slidably attached to the conventional portion of the fishhook, to enter the fish in a location and at an angle different from the location and angle of entering of the barb of the conventional portion of the fishhook, thus insuring capture of the fish. In a second embodiment a flair, on the end of the spearing member nearest the barb of the conventional portion causes the spearing member to enter the fish as the fish becomes hooked in a conventional manner. - 1 -
