Abstract: A device for attracting and/or repelling fish comprises an array of visible light emitting diodes encased in a water resistant, protective housing which is substantially transparent to the visible light emitted by the diodes. In one preferred embodiment, a cylindrical housing containing the diode array is attached to a float, on the upper surface of which is provided a photovoltaic module which charges a battery located in a lower portion of the housing. In other preferred embodiments, the device is adapted to be submerged below the surface of a body of water and is connected to a remote power supply. The device is preferably used to attract fish, with the diodes emitting visible light in the green, blue and violet regions of the visible spectrum.

Abstract: A non-electric perimeter fence to prevent animals from entering a restricted area comprises a vertical barrier member extending to a predetermined height above ground level and an angled barrier member extending upwardly and outwardly from the vertical member relative to the restricted area. The vertical member may comprise a conventional chain link fence and the angled member is preferably made of a sheet material. The surface of the angled member which is presented to an animal attempting to climb over the fence is preferably smooth and free of protrusions which could assist the animal in climbing the fence. Preferably, the height of the angled member is sufficient to prevent an animal such as an adult raccoon from reaching over its upper edge.
