Abstract: An electrical deterrent system and method including a pulse generator, power source, and substrates with accompanying electrodes for attaching to different types of surfaces and supports on various manufactured structures to repel pinnipeds from a manufactured or man-made structure that otherwise is not intended for pinniped use. The system is repeatable, controllable and scalable and includes docking type interchangeable sections.

Abstract: An aquatic electrical barrier that has the electrodes configured in a matrix array configuration, where each electrode element of the matrix array is mounted either directly on the bottom of a water channel or on extendable rods; the matrix array is controlled so that aquatic species may be physically moved by the aquatic species physiological response to a time-varying and spatially-varying electrical field.

Abstract: A system and method to induce fish anesthetizing or narcosis is described that induces a potential field across the body of a laboratory fish having a pair of electrodes, the waveform generated by this potential field is approximately balanced to reduce the introduction of anions into the solution, and a camera is mounted to observe the activity of the fish, so that the potential difference may be adjusted based on the state of the fish.

Abstract: The inventive subject matter describes systems and methods for the remote placement of electrified fish barriers are illustrated and described herein. The inventive subject matter describes a floating electrical barrier that is responsive to the presence of detected fish. The inventive subject matter also describes a multiplicity of electrical barriers that are arranged to create an electrical field that entrains certain species of fish. The inventive subject matter also describes a movable barrier that is used to guide fish from location to location using electrical fields.

Abstract: An electric fish barrier for deterring fish from entering a water intake in a reservoir or along a waterway has a set of conductive members at a first voltage potential and a second set of conductive members at a second voltage potential. The conductive members are disposed on support piles extending up from the bottom of the reservoir. Each conductive member extends vertically between a pre-determined range of depths from an upper depth to a lower depth, forming a contiguous voltage gradient between the two sets of conductive members. Fish are drawn to the attraction flow of water flowing into the intake. The two sets of conductive members are oriented such that the attraction flow passes through the contiguous voltage gradient, thereby deterring the fish from following the attraction flow into the water intake.
