Overfishing is a death sentence to the world’s oceans. As technology continues to improve a great deal of fish can be caught quicker; but at what cost? The effects of overfishing can lead to the extinction of not just the animals being fished, but also the predators that rely on fish to eat. Ninety percent of the ocean’s largest animals have been wiped out due to overfishing (“Overfishing- A Global Disaster”, 2011). National Geographic cites the academic journal Science (2006) that predicts by 2048, all fisheries will collapse due to lack of ocean wildlife. Fish are not the only animal caught in the nets used by fishing vessels. Often animals such as dolphins, sharks, turtles, and seabirds are

Overfishing affects a biome by reducing the amount of species. According to the National Ocean Service (NOAA) the effects of overfishing in a coral reef biome leads to a limited amount of wildlife to reproduce. The ones that do reproduce will be smaller as larger wildlife which spawn more offspring are targeted and removed from the biome causing lower overall birth. This causes more algae to be in the environment which can lead to nutrient pollution due to a lack of wildlife that cleans the area of algae. The World Wildlife Foundation (WWF) found that the effects of overfishing on the ocean also caused imbalances in the populations of wildlife such as tuna and the disruption on herbivores by overfishing such as scallops lead to algae bloom in the ocean as well.

The earliest accounts of overfishing occurred in the 1800s, when the demand of whale blubber nearly wiped out the whale populations. In the mid 1900s, the harvesting of Atlantic cod, herring, and California sardines drove them to the brink of extinction. These high disruptions cause regional depletions of animal resources which is starting to cause a global problem. There has never been a more urgent time for fishing nations to make a commitment towards the sustainability of our oceans. More than 80% of the world’s fisheries have been, or are being pushed beyond their limits and are in dire need of strict management plans. Populations of fish and elasmobranch fish such as tuna, grouper and sharks have been declining to the point where the survival

As the population on earth increases ,overfishing has become a growing issue in all parts of the world. Fish is a vital food source for many, in the world and counts for many of the cultures and heritages in the world, which means there is a high demand for it . This high demand has caused overfishing to occur. This is a cause for concern since due to the development of better technology, there is a higher risk of overfishing if not managed properly. Canada in particular has been facing the problem overfishing for years now. Due to Canada’s issue of overfishing, the environment and wildlife as well as human settlements all have negative impacts ,therefore a sustainable solution must be implemented. If action isn’t taken, Canada’s issue of overfishing will continue to worsen.

"Big Fish in Troubled Waters" by Stephen Ornes informs you that our oceans and water life are being overfished resulting in a decrease in fish.

Overfishing is a global issue that has many negative effects on the environment (Fisheries and Oceans Canada, 2009). Fish are a major resource that many people rely on for not only nutrition, but also for a means of income (Fisheries and Oceans Canada, 2009). As the population of the world increases, so does the demand for fish, which puts oceans under a lot of pressure (Fisheries and Oceans Canada, 2009). Due to advanced fishing technologies and equipment, going out further into the oceans and catching huge amounts of fish is easier than ever (Fisheries and Oceans Canada, 2009). Froese (2004) defines overfishing as capturing the fish before they reach their full growth potential and diminishing their chance of reproduction. In other

The article states, “…there is ample evidence that overfishing is a significant factor in the decline of numerous species and fisheries…” (Allan et al. 1045). This statement alone summarizes the article accurately and illuminates the major problem addressed in the scholarly journal. While relaying an indistinguishable message, an article by Myers and Worm finds a different way of relaying information.

Overfishing and bycatch can lead to many problems and one of the main problems of overfishing and bycatch is the species of fish or marine life going extinct. The consequences of this problem is some of fish and marine life going extinct. When it happens it can affect many things such as not providing certain animals food. It can also lead to overpopulation in some species because there predator might not be alive anymore so without certain species predators will

addition to the effects of pollution, ocean fisheries are suffering the effects of overfishing. A

According to a study done by Living Planet Report in 2015, 29% of the world’s fishing stocks are considered overfished and an additional 61% is fully exploited with no possibility to produce more fish. Our environment is currently afflicted by a number of different problems, one of which is overfishing. Overfishing is defined by FishOnline as, “Fishing with a sufficiently high intensity to reduce the breeding stock levels to such an extent that they will no longer support a sufficient quantity of fish for sport or commercial harvest.” The overfishing situation is being exacerbated by non-sustainable and destructive fishing practices and unfair fisheries partnership agreements; while there are currently attempts being made at fixing these problems and their effects on overfishing, nothing has been extremely effective.

In contemporary society, human society is progressing rapidly on various fronts. Nevertheless at the same time, the problem of overfishing is becoming increasingly worrisome and attract extensive attention of the society. In this essay, I will address overfishing and propose some possible causes of this phenomenon which can give contribution to some solutions.

Another global effect of overfishing is fish farming or aquaculture. It was first started to help preserve the ocean and hoped to help people to obtain a reliable fish source. Unfortunately, what many came to realize is the downside of fish farming. One example is water contamination, where consequently waste products such as foods eaten, feces and other dead fish, are all dumped into our main water supply which contributes to water pollution. Moreover, chemicals that are used to treat the fish farms like antibiotics and algaecides are all released into the ocean; which is a real cause for concern for our oceans. Fish that come from the fish farms are pumped full of drugs, to prevent sickness in the fish but this is not healthy for us to eat. There is also a great environmental impact which includes the fact that to sustain fish farms, portions of

In order for there to be plenty of fish in the years ahead, fisheries will have to develop sustainable fisheries and some will have to close. Due to the constant increase in the human population, the oceans have been overfished with a resulting decline of fish crucial to the economy and communities of the world. The control of the world's fisheries is a controversial subject, as they cannot produce enough to satisfy the demand, especially when there aren't enough fish left to breed in healthy ecosystems. Scientists are often in the role of fisheries managers and must regulate the amount of fishing in the oceans, a position not popular with those who have to make a living fishing ever decreasing populations.

According to the United Nations, 17% of fish stocks worldwide are currently overexploited; 52% are fully exploited; and 7% are depleted. This means that only an estimated 20% of worldwide fish stocks are not already at or above their capacity(Seafarms, 2013). Catches of Pacific herring have decreased by 71% since the 1960s, with Atlantic herring catches falling by 63%. Atlantic Cod catches have fallen by 69% in the same time(Seafarms, 2013). These are just a few of many facts and statistics on the topic of overfishing. The effects of these statistics and facts impact people’s and animal's lives around the

Pollution is a damaging with fish farming. A group of wild fishing being fed to fish in the ocean will eventually transfer disease. As well, fish pollute the water from their wastes. Fish farming also affects the growth and genetics of the fish because they are not in a wild environment. More research should be completed to provide more adequate information and prevent negative outcomes for fish farming.
