Research on Overfishing in the Pacific Ocean: The demand for food across the globe continues to increase as the human population continues to increase. For human populations, particularly people in the poorest countries across the globe, fish is an important source of nourishment and food given the increase in the demand for food. As a result, fisheries catches represent a huge export of energy and mass that can no longer be utilized by trophic levels that are higher than those fished. Since fishing has been used one of the major ways by humans to meet the ever-increasing demand for food, it has contributed to widespread overfishing. The widespread overfishing has in turn resulted in the decrease in the global catch of fish. Furthermore, increased overfishing has become a huge threat to every species in the ocean and has largely contributed to the huge migrations by marine mammals in their quest for the left over fish. While the use of fish by human beings is not wrong, the whole eco-system in the ocean can be severely impacted when human take too much. In order to deal with this issue effectively, it's important to examine its causes, effects, and proposed solutions. The Trend of Overfishing across the Globe: According to the findings of research, approximately 50 percent of commercial marine species have been overfished in the past five decades (Srinivasan, Cheung, Watson & Sumaila, p.1). The increase in fisheries catches across the globe has also been fueled by
Economic activity and our environment have been closely linked since man first discovered the concept of trade. In the language of economics, the environment has itself, become an increasingly “scarce resource1”. Since economics is about managing these scarce resources, it will be a useful tool when considering some of the environmental issues facing our planet. One of the major concerns confronting the environment today is the overfishing of the world’s oceans, depleting some species to near extinction. With continued advances in technological and industrial proficiency, fishing vessels are able to fish across the globe, further exacerbating the effects of overfishing. Because the oceans are considered a shared or common
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
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.
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
The ocean makes up nearly three-quarters of the planet 's surface and contains about eighty percent of the life on earth. Millions of people all over the world depend on seafood heavily as a primary source of food. Americans alone consumed as much as 15.8 pounds of seafood per person in 2009 (NOAA). This is a lot of fish. In fact, it is so much that many populations of fish are going extinct. At this particular rate according to National Geographic, scientist predict that the earth is expected to lose all of its current fisheries by the year 2048 (Roach). The overfishing of our oceans leads to unmanageable practices that will eventually cause many species of fish to become extinct.
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.
Abstract: Overfishing is the process of fishing to the point where more fish are caught than the population can replace through natural reproduction. It may seem profitable to quickly grab as much fish as you can, but it is extremely harmful to the marine ecosystem. The results of this have lasting impacts on the balance of life in the oceans, and the social and economic well-being of the coastal communities who depend on fish for their way of life. Fortunately, there are efforts being done to help prevent this dangerous activity. New Zealand has noticeably led the charge to ending overfishing. Some ways countries have been limiting fishing activities are: marine protected areas, and fishing quotas. These are more of the notable examples,
This issue of overfishing covers vast fields, such as science, humanity, economy, society and nature. The term “optimum”, in regard to the yield from a fishery, is difficult to be defined, precisely and fixedly. Generally speaking, we can describe it as follows: (Niles E. Stople, January 2009, FishNet USA)
Since the beginning of the human race, the ocean has been a major source of food. People near the shores have been taking of advantage of the ocean’s rich and diverse source of nourishment for centuries, both as a source of food and a livelihood. However, since the dawn of the industrial age, humans have begun to take from the ocean more that it can give. As a result, the ocean can no longer provide the human race with the abundance that it once did. As technology rapidly advances, populations skyrocket, and global warming spreads havoc, the ocean’s biodiversity and once abundant supply of fish is dwindling, calling marine scientists and experts to race to find solutions that will restore the oceans health while battling world hunger.
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
Many breeds of fish are being captured at a faster rate than they can reproduce. Some species such as orange roughy fishing became popular in New Zealand in the 1970’s. Over time, it spread to many countries around the world. In the last 20 years, there has been a decline in catch up to 75%. It is no longer common to see in grocery stores as well as restaurants. The amounts of fish that are captured and distributed around the world are alarming opposed to the rate the fish can multiply.
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
