Ocean Overfishing Effects

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

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.

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

Fishing is a great hobby for the “average Joe.” People fish for fun, family bonding, and to make a living. Overfishing, defined as excessive fishing to an extent, damages local ecology. “Overfishing.org”, found at, http://overfishing.org/pages/what_is_overfishing.php, states, “Catching too many fish; fishing so much that the fish cannot sustain their population”. This means that too many fish are taken out of the water too quickly causing a low population count. People who are overfishing oceans, lakes, rivers, etc. are affecting local biological organism and humankind itself. Humans constantly fishing these bodies of water affect the whole food chain. In a few years, your favorite fish may not exist. World powers, such as the United States

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.

Millions of people rely on the ocean for basic nutrition in their diet as well as financially, but the majority of those people do not know what effects of catching that fish might have on the ecosystem. Overfishing has been done for century’s and continues to this day with the first group of fishermen hauling in nearly 500 pounds of fish per fishermen on an eighteen to thirty man vessel in the 11th century. Lack of government also contributes to the problem of life in the ocean to ensure there is an equal balance. Although enforcing laws can ensure the survivability of the oceans ecosystem; cretin fishing companies damage the balance due to the dragging of nets across reefs furthermore removing predatory fish.

Population wise, overharvesting harms the environment for the fish that depend on currently existing species for survival. Extinction of one species means the depletion of food for another—messing with the entire food chain in the process. Overfishing threatens biodiversity, and without it, the coexistence of remaining species and humans will become more difficult. Humans will either have to depend on new sources for food, or lessen their consumption to an extreme extent in order to allow for the regeneration of marine species. Remaining species will also begin feeding off of other things to survive, eventually leading to a possible extinction of additional marine species. Many vitally critical commercial populations of fish—for example, the Atlantic Bluefin tuna—have dwindled to the extent where they are at high risk for extinction if nothing is done to remedy the situation. The depletion of top

Fish have been one of mankind's greatest resource throughout history. They have been sustenance to civilizations in the most extreme climates. But now they are being overfished. There are pros and cons of overfishing. Some pros include more jobs, healthier food, and it provides food for the world. Overfishing should be stopped because the fishing methods that companies use can be very destructive to aquatic ecosystems, they can disrupt balances in the food chain and can lead to the exploitation of non fishing zones/areas, and it can cause overpopulation of other species. Stop overfish and regulate commercial fishing.

Our great oceans whose biodiversity in unmatched, makes up over three fourths of our planet's surface. The ocean is home to more than 20,000 different species of fish and over 2 million other animal and plant species found in our oceans. Overfishing can be defined in a number of ways. However, everything comes down to one simple point: Catching too much fish for the system to support leads to an overall degradation to the system. Overfishing is a non-sustainable use of the oceans. The earliest overfishing occurred in the early 1800s when humans, seeking blubber for lamp oil, decimated the whale population. Some fish that we eat, including Atlantic cod and herring and California's sardines, were also harvested to the brink of extinction by the

Overfishing is an amount of fish than cannot sustain itself. (Fisheries and Oceans of Canada, 2009). Overfishing reduces the fish that are

Overfishing has led to the destruction of ecosystems and resulting in great amount of reduction of stocks in fish and marine mammals from the 11th century onwards (Roberts, 2009). Ocean overfishing is defined as catching fish from sea at rates too high thus lead to depletion of the stock of fish. As today, there are almost 90 percent of fish population have been depleted by humans worldwide because fish is considered as a sources of food. In 2010, 148 million tonnes of fish from fisheries and aquaculture were used by the world and 86 percent of which was used as food for people (Katz, 2012). Besides, according to the non-profit group New Economics Foundation, Ireland, Spain, and Sweden were the worst offenders. Based on a

The world has been industrializing for over a century, leading to better lives for people everywhere. Unfortunately, industrialization often results in an overuse of resources that can often have unintended consequences. In today’s world, industrialization of the fishing industry has led to a rapid decline in many fish species. This is due to a number of factors, ranging from changing ocean temperatures, acidification and degradation of many natural habitats fish depend on, to poor measurement of current fish populations. The main factor in the decline of fish populations worldwide, however, is overfishing on a massive industrial scale. The decline of fish populations could have massive consequences for ocean ecosystems and could result in shortages of fish many communities have grown dependent on not only for food, but to support their local economies. In order to find the best solution to the rapid decline in fish populations worldwide, evidence must be analyzed relating to the environmental, economic, scientific, historical, and futuristic lenses.

One problem that is hurting the world’s oceans is overfishing. Fueled by the overgrowing demand for raw fish and seafood, fishing companies are now using methods that could severely deplete the world’s fish population. This problem is evident in East Asia, where seafood demand has reached record peaks, forcing fishing companies to begin fishing in natural habitats once closed to commercial fishing. Overfishing has

This articles discusses how fish all over the world are going extinct due to overfishing. The world wildlife federation claims that " the planet’s fishing fleet is two to three times larger than the oceans can support" which just lets the reader know how big this problem is. The article also express that this is mostly because the restaurants are exploiting certain species. This is not just occurring to fish, even Maine lobster are suffering.

The overexploitation of the oceans is directly linked to overfishing. Overfishing can be defined 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” (Hilborn and Hilborn, 2012). Post industrial revolution there was an increase in global fishing and consequently an increase in catches. The large scale industrialization of the fishing sector inevitably led to over-fishing, causing the collapse of many fish stocks (Pauly, 2002). Due to unsustainable fishing practices an increase in overfished and fully fished stocks can be observed over time (see Figure 1). The fishing industry has had to adapt in recent times to maintain the quantity of fish being caught, one way they have achieved this is to start fishing at greater depths, today more fish are being caught deeper than ever before (see Figure 2). Deep sea fishing is mostly considered unsustainable, (Norse, 2012) as it
