Military Says Sonar Not A Danger To Fish

I'll be the first to admit this ... I don't know much about sonar. I was infantry, and never had a desire to be in the Navy. My uncles, however, are divers. They have said that sonar will kill all sorts of things ... including humans. How did they study that? I don't know, google it on your own.

The interesting thing about this study is that it was trout only. So does testing only one fish give results for all fish?

Fox News:

The military's use of sonar poses no threat to fish, a new study suggests.

The study was funded by the military, however, and was very narrow in scope: It involved only trout.

The finding, detailed in the July issue of the Journal of the Acoustical Society of America, showed that rainbow trout exposed to high-intensity, low-frequency sonar experienced only a small and presumably temporary decline in hearing sensitivity.

The new study, funded by the Navy, was designed to explore the effects of Navy ship sonar on fish swimming nearby.

Investigators found no damage to the fish's inner ears after they underwent intense sonar exposure, even several days afterward.

The whole subject gives me a headache.
