Next time you are out to dinner and order that delicious Atlantic salmon, the chances are that it is a fillet of a farm-bred fish. Well! Don’t try to whisper to your dinner because there is about a 50 percent chance that the fish had a hearing loss. Scientists in Australia have discovered that approximately 50 percent of farm-bred salmon have a deformed otolith, the fish’s ear bone, which very likely gives them hearing loss. The deformity appears to occur early in life, and the hearing loss is speculated to get worse as the fish matures.
