Methods and apparatus for inducing unconsciousness by warming of the brain of an animal by applying microwave radiation through an applicator are described. An electromagnetic flux concentrator comprises a tubular section of reducing internal cross-sectional area and at least one ridge internally thereof extending longitudinally. The applicator is pre-tuned by directing low-power microwave radiation therethrough to a load that approximates the properties of the animal's head, and adjusting the impedance of the applicator to optimize the impedance match. A compensator associated with the waveguide compensates for changes in detected reflected power.

A poultry stunning apparatus including a trough for containing water through which the poultry is carried for stunning. The apparatus also including an electrical control module configured to apply a DC current to the poultry at a voltage sufficient to stun the poultry and to apply AC current to the stunned poultry at a voltage and for a period of time sufficient to immobilize and relax the muscles of the stunned poultry, while at the same time avoiding or minimizing damage to the poultry tissue. The apparatus further including a stunning electrode positioned within the trough, the stunning electrode including a metal plate adapted and positioned within the trough to be contacted in a contact zone by the poultry as the poultry are carried along, the contact zone of the metal plate being substantially smooth and uninterrupted.

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.

The present invention discloses a food source for predatory mites and/or insects comprising a mixture of a carrier material and individuals of at least one mite species suitable as being a prey for the predatory mites and/or insects. The present invention further discloses methods for producing the food source and uses thereof.

A portable system for handling and affecting a physiological state of an aquatic species with a pair of gloves, a multiplicity of electrodes, and a pulsator attached to the electrodes, so that when the pulsator is activated the current, alters the physiological state of the aquatic species. The system providing a regulated current output to control the flow of current through the aquatic species held between the pair of conducting gloves.

[Problem]

To provide a fish sedating device capable of reliably energizing and sedating fish to satisfactorily perform a slaughter operation.

[Solution]

The fish sedating device includes fish placement means 3 on which fish F can be placed, electrodes 4a and 4b that energize the fish F placed on the fish placement means 3 through high-resistance water in a state present on the fish placement means 3 and having a higher electrical resistance than that of the fish, and a power source that supplies electricity to the electrodes 4a and 4b.
