No wonder it is so popular among tournament fishermen. The distinct curved shape of the circle hook will, when the fish takes the baited hook and swallows it, ensure that the hook travels to the corner of the mouth or lip, resulting in fewer deep-hooked fish. The circle hook can be used for a whole range of applications from drifting with live bait for Tarpon or trolling for Marlin with bridle rigged to deep-dropping for Swordfish. When live baiting always match the hook size to the bait.
