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.

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.

In the lab, we trained young damselfish to recognize the odor of the predatory dottyback as a threat.

Some fish were trained in the presence of boat noise, while the others were trained with the ambient sound of the ocean.

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.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.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.Nowadays, the underwater soundscape includes the roar of motors, the ping of military SONAR, and the bangs and blasts from offshore development.For fish, whales, and other marine animals, intense underwater noises from blasts can cause acoustic trauma and even death.More and more, scientists are discovering that noise not only interferes with an animal’s cognitive processing of sounds, but also other types of stimuli, such as sight or smell.For example, boat noise interferes with the visual signals that cuttlefish use to communicate with each other.Disclaimer: This work has been submitted by a student.This is not an example of the work produced by our Essay Writing Service.
