An underwater device for subduing underwater invasive species includes a translucent or transparent fixture having a TiO2 coating on at least one side of the fixture and a light source positioned to expose the coating with light having sufficient intensity and selected range of frequencies to activate the photocatalytic TiO2 coated fixture.

A portable sterilizer according to an embodiment of the present application is capable of spraying ultra-fine chemicals, and includes a housing in which a space is formed and an injection nozzle is provided at a front end thereof, a chemical tank provided on one side of the space of the housing, a chemical feed pipe formed between the chemical tank and the injection nozzle, and a water pump which is installed on one side of the chemical supply pipe to supply the chemical to the injection nozzle through the chemical supply pipe.

Systems and methods for effectively repelling pest animals (e.g., birds), including drones that adopt complex deterrent strategies (e.g., cooperative strategies), establishing a fuzzy boundary for a geofenced area and altering pest deterrent device flight patterns based on the characteristics of the fuzzy boundaries. Deterrence strategies can be selected based on the type of pest animals, and new deterrence strategies can be generated based on outcome feedback from previous strategies (e.g., combining aspects of preexisting deterrence strategies by utilizing an AI system). Drones can be automatically maintained by comparing current drone operational status with a predetermined threshold level. A maintenance robot (e.g., a drone) can autonomously rescues a working robot (e.g., another drone) that is in trouble.

An organism eradication system and method of use configured for capturing and treating target organisms in a body of water, wherein the target organisms enter the system through a concentrator, are exposed to and mixed with an agent in a mixing section, and then die off over an appropriate dwell time with related environmental catalysts in a holder.

A system for the elimination of parasites adhered to fish. The system includes an entry and drainage area configured for the fish with parasites to enter the system, the entry and drainage area joined to an application area through which the fish with parasites pass and come into contact with curtain electrodes and/or grill electrodes. The system includes spray nozzles at least partially housed in the application area and a return chute at least partially situated below the application area to receive and channel the sprayed water. The system also includes a pump that pumps the water to the spray nozzles and an outlet through which the fish without parasites exit the system.

A method and apparatus involving a euthanasia process are provided. The euthanasia process is carried out in a chamber including electric stunning to induce insensibility and reduced atmospheric pressure to induce hypoxia. The described method and apparatus provide a more humane system for euthanizing animals and reducing any negative impacts for people carrying out the process.

An electronic bait box assembly for storing earthworms includes a box for containing earth and earthworms. A lid is removably attached to the box for closing the box. A voltage unit is coupled to the bait box and the voltage unit is in electrical communication with an interior of the box. Moreover, the voltage unit is placed in electrical communication with the earth that is positioned in the box. The voltage unit induces an electrical voltage through the earth when the voltage unit is turned on. In this way the voltage unit urges the earthworms to move upwardly in the earth thereby facilitating a user to remove the earthworms for fishing bait.

It is disclosed a device for controlling and/or euthanizing vermin or pests for preventing such vermin or pests from entering into a geographical area or into a building, wherein the device comprises at least one completely or partially uninsulated electrically conducting wire or conductor connected to an electrical current source, providing controlled electrical pulses to said conductor or wire in the form of pulses or pulse trains. The device may be used in a method for controlling the access of pests/vermin to a geographical location, building or property wherein the electrically conducting wire(s) lead(s) an electrical current with an amperage of not less than 0.0001 A. The device and method is particularly suited for removing/controlling pests/vermin on land.
