A submersible (10) and method of using a submersible for capturing a target species comprising: at least one controllable thruster (14) for manoeuvring the submersible; at least one camera (12) for capturing images to allow the identification of an individual of a target species; a catapult mechanism (33) wherein the catapult mechanism is reversibly moveable between a released configuration and a primed configuration by an activatable motor, and wherein the catapult mechanism may be loaded with a retractable device mounted on the catapult mechanism, and the retractable device may be launched from the submersible by being propelled by the catapult mechanism; a container for receiving a captured individual.

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.

A system includes a fish stunner configured to stun fish within a stunning zone of a waterway and a conveyor with a portion of the conveyor located below a waterline of the waterway and a second portion of the conveyor located above the waterline such that fish that have been stunned reach the conveyor and are lifted out of the water by the conveyor.

A system for repelling sharks is disclosed. Magnets are connected to a rod along its length. If necessary, the rod may be extended. Additionally, one or more flotation devices may be connected to the rod to manipulate or adjust the buoyancy of the system, depending on the user's objective(s). The rod is connected to a fishing line once a fish is hooked and is in close proximity to the boat or other structure from which the fisherman is fishing. The weight of the rod and magnets cause the rod to slide down to the end of the fishing line, where the rod will come in contact with the hooked mouth of the fish. As the fish struggles during the fight, the rod creates a protective magnetic field around the fish to deter sharks from engaging the fish.

A sensor assembly for a castable lure is provided including a pressure sensor configured to measure a water pressure applied to the castable lure when deployed in an underwater environment, a processor, and a memory including computer program code. The computer program code configured to, when executed on the processor, cause the processor to receive pressure data from the pressure sensor, correlate the pressure data with time stamp data, cause the pressure data and correlated time stamp data to be stored in the memory, determine a data connection status between a transceiver and a marine electronic device, and in response to determining that a data connection exists, cause the pressure data and the correlated time stamp data to be transmitted to the marine electronic device. The pressure data and correlated pressure data correspond to a depth profile for a cast of the castable lure.
