Fishing with gaff hook. In fishing, a gaff is a pole with a sharp hook on the end that is used to stab a large fish and then lift the fish into the boat or onto shore. Ideally, the hook is placed under the backbone. gaff cannot be used if it is intended to release the fish unharmed after capture, unless the fish is skilfully gaffed in the lip, jaw, or lower gill using a thin gaff hook. A flying gaff is a specialized type of gaff used for securing and controlling very large fish.
Flying Gaff. Fishermen who target large marlin, shark or tuna use a flying gaff. This specialized version has a long rope tied to the base on the end of the gaff. When the fish is struck, a quick jerk on the pole separates the gaff hook, leaving the angler with what is now essentially a hand line.nglers should simply ease the hand gaff under the lower jaw while steadying the fish by holding the leader. Then, the gaff should be raised with a steady pressure to find the sweet spot between the jawbones. A hand gaff is best used for fish under 76 cm and/or 9 kg.
