The fish trained in the absence of boat noise, however, were scared. We taught another group of fish to recognize the smell and sight of three common predators — in the presence or absence of boat noise — and then we released them back into the wild.It turns out that fish don’t learn very well in noisy environments.

More common quieter noise, such as construction or shipping noise, may not kill the animals directly, but can disrupt their ability to find food, mates, or avoid predators.

A wide range of species use acoustic signals to communicate with each other.

In some places, such as biodiversity hotspots or sensitive habitats, it may be prudent to create rules or laws that minimize the impacts of noise.

Approaches to mitigate the effects of boat noise may include the implementation of quiet zones, speed restrictions, or the use of mufflers or low-volume engine models.

Today’s seas continue to face these threats, as well as from habitat destruction, warming, and ocean acidification.

Noise Pollution is one type of the volume which makes diseases into the environment and it very harmful for the people who are breathing and living on this earth.We found that fish trained with boat noise showed no fright reactions when they were exposed to the predator.It was as though they had had no preparation at all.Recent research in our lab indicated that noise can also impair an animal’s ability to process the chemical information released after a predator attack on shoal mates.We looked at the effects of noise from small motorboats on coral-reef fishes at Lizard Island Research Station at the Great Barrier Reef in Australia.After three days, only 20 percent of the fish exposed to boat noise were still alive, compared to almost 70 percent of unexposed fish.We often think of the ways climate change, overfishing, and run-off pollution threaten fish populations in the Great Barrier Reef, but our study adds to the growing evidence that boat noise may also contribute to fish death through a failure to learn.Boat noise can have a variety of negative impacts on fishes.It can change their activity, force them to live in bad habitats and decrease their ability to feed, defend their territory, reproduce, and avoid predators.Marine fishes, for instance, are known to make chirps, pops, knocks, and grunts using their teeth, swim bladders, or fins.One consequence of anthropogenic — humanmade — noise is a masking effect.
