13 Effects of Ocean Noise Pollution on Marine Animals

by Rini

Noise due to human activity that is increasingly occurring in the sea certainly has an extreme impact on animal life in it. For example, large mammals such as whales can lose navigation when they hear sounds that are too noisy or above their hearing averages. Why is it often found whales stranded on the beach? This has resulted in the death of these large animals. Hence coastal pollution, understanding, causes, impacts, and prevention.

We have found evidence of disturbing noise from all waters in the world. One of the causes is large ship traffic and sonar waves from offshore oil exploration and military training. Well, here are the effects of ocean noise pollution on other marine animals as below:

1. Damaging Animal Hearing

Sole reason why loud noises cause danger to the life of mammals underwater is because it will disturb the hearing of animals such as whales, whale shark, dolphins, and other large animals. These animals are very sensitive to hearing, they can only hear the sounds each of them make.

So that noise carried out by humans, both from tanker ships, warships, oil drilling and so on can make their hearing disturbed and even worse it can be damaged for a long time. Therefore, if it’s left unregulated, it can cause more serious damage to nature. The problem in the causes of pollution in the sea that you must pay attention to.

2. Damaging Navigation in Animals

Besides being able to damage the hearing of marine animals it turns out that noise pollution is also capable of disrupting the navigation functions possessed by animals in the sea. For example, navigation is used by dolphins to find food locations, search for collections or find locations for a population.

With the noise that exceeds the ability of the animal to communicate, it will make their navigation become chaotic. Therefore, it is often found that large animals get lost to the shore and shallow seas. As a result of them getting lost, of course, affects the population and the survival of these animals.

3. Cause Marine Animals Stranded

The effects of ocean noise pollution on other marine animals is that the fish will be stranded. Sound noise generated from human activities in the sea will interfere with hearing and navigation functions of animals such as whales, dolphins, sharks and so on.

This will drive them to a lost situation, which eventually causes them to strand. This condition often occurs and looks very worrying. This if it drags on the longer it will affect the population in these animals, eventually becoming extinct. The harmful effects of ocean pollution need to watch out.

4. Many Sea Animals Get Lost

Many cases of stranded animals make their lives hampered. Because the animals stranded will surely die, survivors are only a small part of them. It cannot be denied that the serious impact of noise pollution can damage the ecosystem of creatures on the sea floor.

Although these animals live in deep water depths, if the sonar sound is very high, it can be an obstacle to communicate and looking for a healthy population to marine animals. So that the reproduction process of animals becomes declining, which is why the impact is so serious in many cases.

5. Causes Sea Sound Pollution

The impact of noise pollution also affects the lives of fishes, for example, the ability to reproduce, communicate and avoid predators. There is a case where a number of studies have reported that herring in the Atlantic, blue fin codes and tuna turned out to avoid overly noisy environments.

This means that noise levels affect the distribution of fish because fish tend to avoid areas affected by man-made noise pollution. Sound pollution can significantly affect communication between fish. Fish produce sound when fighting to defend territory, fight for food or are avoiding predators. The dangerous if the future effects of ocean pollution.

6. Inhibiting the Growth of Marine Animal Reproduction

Furthermore, the effects of ocean noise pollution on other marine animals can inhibit the growth and reproduction process in fish. If this happens, it will be difficult for fish seeds to grow normally, possibly will die if exposure to noise is too high in one area.

This is the cause of declining numbers of fishes in the sea, of course, the impact on human needs for fish. And also the sustainability of large fish populations is also disturbed until finally their lives are damaged and extinct.

7. Inhibiting Inter-Marine Communication

Noise from other human activities can also have an impact on the communication of animals in the sea. Because the sound produced can play an important role when the fish are looking for a partner and make a sexual selection among the fish in the sea. They can also communicate with each other if the noise is too high the fish will find it difficult to find and communicate well.

So that there were cases of stranded fish, straying from the group and looking for other, quieter places to populate and communicate. Sound pollution also causes fish to not be able to hear sounds between them and reduce their communication skills. The effects of ocean pollution on human health which need to be noticed.

8. Fish Population Will Decline

The effects of ocean noise pollution on other marine animals is causing the fish population to decline. Besides that it can also affect the distribution of fish, noise pollution also affects the reproduction process of fish because it causes stress, limits their ability to find partners or keep them away from the location of laying eggs.

That is why it affects their life, their population. Especially large fishes will find it difficult to survive. Seeds that are supposed to grow will become extinct and the parent’s reproductive process will be disrupted.

9. Fish Will Be Difficult To Detect Prey

In addition, the ability of fish to detect prey or hear predators is also far down. if the effect of this disorder continues repeatedly then in the long term it can cause stress, weaken and ultimately to birth also recognize its prey. The distance from the sound source must be known as a result, because this animal changes its natural behavior.

For marine mammals that do not belong to a group of sound sources, it can be very dangerous for them, especially to meet a larger or dangerous predator. The possibility of survival for these fish is greatly reduced. The effects of pollution on coral reefs you should pay attention.

10. Breaking down a set of fish in the ocean

Noise can also affect the disruption of a group of fish that live in groups. Communication between animals in the sea is damaged, if this often happens, navigation, communication, and development among these animals will disappear. As a result of these factors, gradually the life of fish will become extinct.

Failure to reproduce, give birth to seeds, find partners, avoid prey is difficult to track properly. Sound noise in the sea has caused short-term effects including prey on food, socializing, and vocalization and behavioral changes in diving. As a result, the sound can cause marine mammals to move from their own habitat to a quieter place.

Apart from the examples and explanations above, here are the effects of ocean noise pollution on other marine animals that you can know about:

  •  With the noise generated from human activities, animal life such as whales, sharks, dolphins are hampered. Like their needs in finding a partner and also developing breed, this will have an impact on the decline of generations of aquatic animals in the future. Find out the destructed effects of ocean pollution on marine plants.
  • Often because noise pollution can eventually make the inhabitants of the ocean move away from that location. Fish certainly do not like the noise, because fishermen will generally avoid noisy zones. Because the fish will be difficult to catch even at all do not want to approach at the location of the noise.
  • The most serious effect of noise impacts is high levels of pollution. In the future, of course, there are no more fish that can be used as human needs. The balance of the marine population also becomes damaged and extinct, imagine if the sea is without any living creatures in it.

So those are how serious and dangerous is the effects of ocean noise pollution on other marine animals for a long time. Anyone must be able to maintain and maintain life in the sea far from pollution and pollution if the survival of generations will continue.
