Does noise pollution affect fish at all?

    Yes, noise pollution does affect fish. Most fish can hear and are influenced by noise levels, including man-made noises. Increasing noise levels can have an effect on the population of fish, for it affects their ability to reproduce, communicate, and escape predators. The sensitivity to noise differs depending on the type of fish. Atlantic cod, for instance, have an average sense of hearing, whereas freshwater goldfish hear at higher frequencies. Many fish detect their predators through sounds, and when noise pollution becomes a factor of distraction, some fish may not be able to flee. Some species use sound to communicate with mates, and so noise pollution may cause stress and lead fish away from spawning sites. While noise pollution may not be devastating, it certainly can greatly affect a fish’s life.
