Can fish be killed by sonar?



  1. 0 Votes

    The University of Maryland actually performed a study in 2007 which found that sonar does not kill fish. Some of the trout that were tested had some slight behavioral changes, but no mortality. The fish were exposed to the sonar signal much longer than they typically would be in the wild. All of the tissue and organs in the fish (what is feared could be affected by sonar) showed no signs of decline or damage.
