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. The grip includes a front surface, a rear surface and a lip formed along the forward edge of the grip. The apparatus, and specifically the curved region in the shank, is configured to allow the pointed end of the shank to penetrate a target below the target's skull and, upon continued insertion, penetrate the brain/brain stem of the target thereby humanely dispatching the target.

A fish stunning device includes a submersible main body with a watertight interior that houses an electronic suite. The main body is securable onto a fishing line and includes internal weights for traveling underwater along the length of the line. A plurality of resilient malleable protrusions each having an electrode extend outward from the main body. Each of the electrodes is connected to the electronic suite and function to impart an electrical shock onto a fish that is engaged with a hook on the end of the fishing line. The electronic suite has a power source for receiving and storing an electrical charge and a power output unit for amplifying and discharging the electrical charge to the electrodes. A system controller communicates with a pressure switch and a user interface to selectively activate the electrodes underwater.

An apparatus for stunning an animal with an exhaust gas mixture includes a stunning chamber located at a processing site to contain therein as many an animal selected to be stunned; and a combustion chamber located at the processing site for combusting a mixture to provide therefrom an exhaust gas mixture which includes carbon dioxide for stunning the animal in the stunning chamber.

An apparatus for stunning, in a stunning chamber, poultry animals for slaughter supplied in transport containers, includes a stunning chamber, a transport device for introducing the containers into the chamber, transporting therethrough and discharging therefrom. The stunning chamber has a vertically oriented stunning shaft. The transport device has a lifting device to lower each container into the chamber, top to bottom, on a first transport path. Each container is transported in the stunning shaft bottom region transversely from the first to a second transport path and is lifted, bottom to top, on the second path. A device in the shaft bottom region introduces stunning gas into the shaft to form inside the stunning chamber a stunning medium of ambient air and stunning gas. A ventilation system inside the stunning shaft circulates parts of the stunning medium in an upper region of the chamber. A method is also provided.

A related method and exhaust gas mixture are also provided.

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.

A poultry stun detection system is designed for using with a poultry slaughter platform, wherein the poultry stunning detection system includes at least: a first camera device, a second camera device, a network transmission device, and a computer processing device. The poultry stun detection system utilizes visual devices to immediately determine whether the stunned poultry still has perception in real time, and employs the YOLOv4 deep learning model to enhance the recognition accuracy of whether the poultry has lost its consciousness after stunning.

The present invention relates to a fish stunning apparatus, comprising a fish supply device adapted for conveying fish head first, a fish receiving space (10) configured by means of the fish supply device, to be loaded with fish in a head first position, a positioning means (11) with a positioning means (12) engaging the fish head, which is adapted to hold the fish in a stop position in the fish receiving space (10) for stunning the fish and to release the fish after stunning, a stunning means (13) acting on the head-side region of the fish for stunning the fish in the stop position, a trigger device (16) adapted for determining the stop position and for triggering the effect of the stunning means (13) on the head-side region of the fish, a control unit adapted for controlling the positioning device (11), the trigger device (16) and the stunning means (13), a fish size sensing device adapted for determining the fish size, a controllably moveable position actuator, which is adapted for locally adjusting the fish positioning means (12) in such a way that the respective position of the fish head relative to the stunning means (13) in the stop position is adapted to be adjusted in a self-actuating manner depending on the fish size and is characterised in that the fish size sensing device comprises a fish length sensing device adapted for determining the fish length and the fish size sensing device is configured for determining the fish size on the basis of the fish length. The invention further relates to a method for automatedly stunning fish.

A method for processing a live fish can include: determining a set of fish attributes of a fish, optionally sorting the fish based on the set of fish attributes, euthanizing the fish, exsanguinating the fish, and/or any other suitable steps. In variants, the method can additionally or alternatively include: discarding the fish after sorting, further processing the fish, and/or tracking the fish. However, the method can additionally and/or alternatively include any other suitable elements.
