Increasing manmade sounds underwater make fish deaf.
Michael Smith, an assistant biology professor at Western Kentucky University, cited U.S. Navy sonar and oceanic shipping as possible noise pollution for fish, which use sound to find their way around and listen for predators.
His study will expose locally bought rainbow trout, silver perch and goldfish to various sound combinations at a special sound booth.
Then tests will see whether the fish have hearing loss. The fish's brain waves will be recorded through electrodes while the fish listen to tones.
"We give a series of pure tones to fish through an underwater speaker, and we increase the intensity of the tones until we detect brain-wave activity," Smith said.
It has long been understood that the West has been trying to subject Russian borders to total control. We have not seen such activity even during the Cold War
