Abstract
A cover for eliminating marine life from the intake of a water intake positioned beneath the surface of a body of water. The cover is placeable over a water intake and is provided with a plurality of apertures formed therethrough which permit water to flow into the water intake. An electrical wire is embedded in a spiral or serpentine fashion within the cover. An insulated cable connects to the embedded wire and provides a radio frequency signal from an external source of power. The wire radiates radio frequency energy over the surface of the cover so that sea mussels and other marine life which have accumulated on the cover are repelled or killed. In a different configuration, electrical heating elements are connected to the wire and generate sufficient heat to drive off or kill the marine life. In a further embodiment, a sonic generator is attached to the cover and generates sonic waves which achieve the same result.
