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.
With the possible exception of a large tuna, flying gaffs are seeing less use every year as fewer and fewer of these critically over fished species are taken by recreational anglers. Gaffing Tips: 1  Make sure the gaff hook is facing down and toward the boat as the fish is brought alongside. Once a fish is on the gaff, the angler should back off on the drag or disengage the reel with the clicker on. 2  Donât attempt to gaff a fish that is too deep and beyond reach. 3  Be patient and wait for a clean shot. 4  While waiting for the gaff, the angler should never lift the fishâs head out of the water.
