An electric gaff hook device includes an elongated pole having at least one hook that is positioned along the distal end. Each of the hooks including a curved shape, a sharpened tip, and a plurality of electrodes. A controller, user interface, power source and power output unit are provided along the pole. The power output unit receives power from the power source and sends amplified power to the plurality of electrodes based on a command from the user interface. The power discharged by the electrodes functions to stun and immobilize a fish for between about 1 and 3 minutes. A spike is provided along the distal end of the pole and includes a plurality of apertures forming a channel for receiving an elongated wire to euthanize and perform ike jime on the stunned fish.

A pneumatic stunner for stunning an animal has a piston slideable within an inner chamber, and a stunning rod driven by the piston forward and rearward towards and away from the front end of the housing. A fire pressure chamber has an annular configuration disposed adjacent the rearward or central end of the inner chamber. A return pressure chamber has an annular configuration disposed adjacent the forward or central end of the inner chamber. A valve system alternately controls flow of the pressurized fluid from the fire pressure chamber to the rearward end of the inner chamber to move the piston and drive the stunning rod forward to stun an animal, and from the return pressure chamber to the forward end of the inner chamber to move the piston and drive the stunning rod rearward and retract the stunning rod. The handle includes a cushioned mount adjustable in direction.

An animal stunner for use in livestock/slaughterhouse operations has a piston slideable within an inner chamber, and a fire pressure chamber with an annular configuration disposed adjacent the rearward or central end of the inner chamber. A stunning rod is driven forward by the piston to stun the animal and rearward to retract the rod. A valve system alternately controls flow of the pressurized fluid from the fire pressure chamber to the rearward end of the inner chamber to move the piston and drive the stunning rod. A catch system holds and releases the stunning rod. A compressed fluid supply is used to retract the stunning rod between operation cycles. Handles employing triggers are used by the operator to hold the stunner and to activate the valve system, and cushion mount systems are attached between the handles and stunner housing to absorb shock while operating the stunner.

A catch engagable with a catch pivot ring for capturing and releasing a stunning rod moveable along a longitudinal axis in a pneumatic animal stunner for stunning an animal. The catch comprises a plurality of arcuate sections substantially forming a cylinder, each arcuate section having a forward end and a rearward end. The catch includes an inner wall toward the longitudinal axis and an outer wall away from the longitudinal axis. The catch includes a flange at the rearward end of the arcuate section extending outwardly directly from the outer wall and away from the longitudinal axis and a lip at the forward end of the arcuate section extending inwardly from the inner wall and toward the longitudinal axis. Each of the arcuate section flanges is engagable with an inner lip of the catch pivot ring allowing the arcuate sections to pivot about the catch pivot ring inner lip.

A pneumatic animal stunner employing a stunning rod includes a catch mounted within the housing for alternately holding and releasing the stunning rod. A catch piston is disposed adjacent the catch on a side away from the longitudinal axis, and is in sliding contact adjacent the catch end portion and out of contact with the catch body portion. The catch piston slides between a first position urging the catch end portion toward the stunning rod longitudinal axis in the hold position, thereby holding and preventing the stunning rod from being driven forward, and a second position permitting the catch end portion to move to the release position away from the stunning rod longitudinal axis releasing and permitting the stunning rod to be driven forward. Valves control air flow to cause the catch piston to move between the first and second positions.

A method, system, and apparatus for humanely dispatching wounded game in the field comprises a shank with a connecting end, a curved region, and a pointed end, connected to a grip formed at the connecting end of the shank, and a finger loop. The grip can further comprise a series or flattened portions configured to engage the gaps in a choke tube in order to remove the choke tube.
