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.
