In one aspect, a fishing gaff includes a shaft, at least a first grip circumscribing a grip end segment of the shaft, and a hook member engaged with a hook end segment of the shaft. The hook end segment of the shaft is opposite to and longitudinally spaced from the grip end segment of the shaft. The hook member includes a shank extending longitudinally along the hook end segment of the shaft, an engagement segment located proximally on the shank and extending transversely away from the shank into a transversely-oriented hole of the hook end segment of the shaft, and a piercing element configured to pierce fish that is located distally on the shank. The piercing element extends distally beyond a distal end of the shaft. The fishing gaff also includes a coupling member disposed circumferentially around the shank to hold the shank onto the shaft.
