The Environmental Impact of Fisheries and Fish Farming on a Global Scale

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

There are also some negative effects that fishing has on the environment. Destructive fishing practices devastate the marine environment and include bottom trawling, bycatch, the use of poison and explosives, and ghost fishing. The larger and better equipped boats mean the more devastating the impact of illegal fishing techniques. Bottom trawling is an industrial

“The world’s smallest porpoise is slipping closer to extinction…” (Malkin). This propoise is called a vaquita, and they are getting run into extinction because of drift nets set of a larger porpoise called the totoaba. A drift net is a large net that is placed underwater for catching fish. Michael Pollan, author of The Omnivore’s Dilemma, talked about destroying the ecosystem through farming, but he didn’t mention how it could happen through fishing, too. Fishermen should stop using drift nets to collect fish because they can catch the wrong species and destroy the ecosystem.

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

Commercial fisheries can do tremendous damage to the marine ecosystem if they are not managed properly. This became apparent in Newfoundland and Labrador during the 1990s, when decades of overfishing caused the northern cod stocks to collapse and resulted in a moratorium on the centuries-old industry. These were huge ecological and economic losses, which dictated an urgent need to change fisheries policy and practice in a way that would make the industry sustainable and protect marine biodiversity.

The earth’s oceans are overfished. Nearly 80 percent of commercial fisheries are overexploited and some experts believe that global fisheries will completely collapse by 2048 (Barkin page 1). While these are just facts that tell the worst-case scenario, they should be alarms that spark change in the way we fish. This paper, however, will specifically target overfishing in the Grand Banks in Newfoundland, Canada, and analyze its impact on Earth, its Environment and Humanity. Over fishing is simply when fishermen catch more fish than are being reproduced. Eventually the stock of fish in the environment will be completely depleted. That is exactly what happened off the shores of Newfoundland in 1992. With Cod fishing at an all time high, the Canadian government discovered that the Cod population was almost exhausted. New technology and poor decision-making led to the complete destruction of the cod population in the Grand Banks and this is a mistake that we should never repeat.

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

Myers’ and Worm’s article “Rapid Worldwide Depletion of Predatory Fish Communities” (“Rapid Depletion”) focuses on the same pressing matter of overfishing, but their article gravitates more towards statistics and figures. For example, Myers’ article states that a suggested 90% of large predatory fish are no longer present in our oceans. Myers uses blunt facts to reveal the severity of overfishing to readers. Studies have concluded that for a given area of ocean opened up to commercial fishing, an 80% decrease in target species may be found in as little as 15 years. With numbers like this, it is no surprise that our oceans are in such a crippled state. Harmful methods of catching species

Commercial fishing has a great affect on the marine life for many reasons. Those reasons include species of marine life going extinct, or over population. Some marine life are going extinct from overfishing because as scientists said fish are able to produce only a limited quantity of fish over time this problem cannot only affect the fish but it can affect the entire ecosystem in the ocean. Some species of fish are also going extinct from bycatch. Bycatch is when other species of fish or marine life is captured in the nets with the target fish that is supposed to be caught. It is estimated by scientists that 25 percent of the commercial fishing industries around the world harvest is discarded bycatch. Some species of marine life cannot only go extinct but it can also overpopulate. Certain types of marine life can go extinct because their predators are going also going extinct. This issue arose in the early 1900s when commercial fishing industries expanded their fishing fleets.

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.

Overfishing’s status as the focus of public concern mainly results from its negligible but harmful influence on individuals, collective, and even the whole world. One of the world’s significant fishery in the East China Sea is damage by overfishing and growing levels of contamination, recent research has shown, confirming the fear of fishermen and environmentalists.

The main causes of overfishing are poor fishery management with a lack of regulation, unrestricted access to the ocean and illegal fishing. During the last few decades the demand for edible seafood globally has skyrocketed and the high demand is causing us to overfish to keep up with the demand. Unfortunately, fisherman are catching more fish than can be naturally reproduced. There are only limited regulations in place, which means that fishing companies are basically fishing when and where they want to with out any oversite. Overfishing causes such serious effects such as the ocean life getting knocked out of balance. Coastal communities rely on the benefits of the fishing for social and economic health. When we overfish it

How often do we stop and think about the people that fish to provide the rest of the world with the supply of fish that is in demand. With many fisheries closing down due to poor managing and depletion, anglers are turning to the deep sea to fill their “fish orders”. Large fishing vessels also known as Super Trawlers are dragging fishing nets up to a mile deep. Doing this allows them to catch as many fish as possible, but it is also destroying natural habitat such as coral reefs that have been part of the sea for thousands of years. The effect of this is devastating to sea life.

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
