The overfishing of our world’s oceans is causing a depletion of some prize fish, such as tuna and swordfish, to the point that some scientists believe that 90% of these big fish populations have been fished out. Jeremy Jackson of the Scripps Institute of Oceanography published a study in 2001 in which he asserts that overfishing is more destructive than toxic pollution or degrading water quality (University of Phoenix, 2007). Dr. Daniel Pauly, Professor and Director of the University of British Columbia's Fisheries Centre, describes it as follow on The Overfishing.org (2007) website: “The big fish, the bill fish, the groupers, the big things will be gone. It is happening now. If things go unchecked, we’ll have a sea full of little horrible things that nobody wants to eat. We might end up with a marine junkyard dominated by plankton” (Fishing down the food web, para. 1).

Among the scientific community there is little argument on how to resolve this issue. Research has found that the situation is reversible if addressed now, but states that it will require a change in attitude in how we are using the oceans (University of Phoenix, 2007). To address this issue now, so that we may sustain the world’s big fish population for future generations, we must create a plan of action that includes the following steps (Young Peoples Trust for the Environment, n..d.).

• Begin with quotas on fish. We can base this quota on scientific estimates of which fish are the most severely depleted, and adjustments can be made to the quotas according to reassessments done every few years as we monitor the repletion of the fish populations.

• Larger nets must also be used. As the big fish population has declined, mesh size has gotten smaller. We must increase this back to the original mesh size used perhaps 40 years ago, to allow the

    To what extent are more recent developments in cold environments sustainable ? Fishing can disrupt food chains. For example krill fishing in the southern ocean is depleting food supplies for whales and penguins. Overfishing of a species can severely deplete its population, sometimes beyond recovery. Overfishing of the patagonian toothfish in the Antarctic is currently a concern. Bottom trawling catches fish by dragging nets along the sea-bed. This disrupts the eco system by reducing light levels thought increasing turbidity and catches other species as well as the target one. Its carried out in the gull of Alaska, the greenland sea and the barents sea. Fishing quotes have been introduced to limit the number of fish caught and prevent overexploitation of the resource.…

    In 1994 governments attempted to bring up the failing fisheries when worldwide the fisheries spent $124 billion to catch the fish but, got $70 billion out of it so the governments covered up the shortfalls. Coral reefs are on the verge of collapse because of overfishing. Also the coral reefs have decreased from about 28 percent to 13.8 percent. About 19,300 square miles of coral reef has been lost due to overfishing. See humans and animals are being affected by commercial fishing and overfishing.Humans could find another food source other than fish and for the government to pass a law that commercial fishing should be changed the way it is done. Doing this will solve the problem by leaving the fish alone so they can repopulate and the fish population will be restored. By the government passing the law then, commercial fishers will have to choose a less damaging way to catch fish. They could use rods instead of a huge net so you will be able to quickly decide what you want to do with the fish instead of killing fish by bycatching. So to find another food source the government could tell people to hunt more common deer and…

    Robert ‘Ben’ Johnson Engr. 183-EW 10/31/12 North Atlantic Cod Commons: Overfishing and it’s Solution Over fishing has led to an almost complete wipe out of the mature cod population in the area of Northern Europe. With lack of regulations, the world could witness an entire species of fish destroyed due to rational behavior of man to want more. This is a classic example of a “commons” which Garrett Hardin discusses in his essay “The Tragedy of the Commons” (Hardin, 1968). The North Atlantic Cod is a natural resource that, although regulated minutely, is being overfished and exploited. Even though the fishing industry is an important industry that feeds many third world countries and provides income to most of those countries also, allowing the exploitation is unacceptable. Today’s society is not effectively reducing or efficiently stopping the damage that is being done to the populations and environment. In order to solve the problem of over fishing cod in the Northern Atlantic we must apply a combination of technical and ethical solutions. I would have the United Nations pass specific laws regulating major fish populations which could be an extension of the Third Committee: Social, Cultural, and Humanitarian or (SOCHUM) of the United Nations. I would also have specific incentives put up by SOCHUM to promote research into developing more widespread aquacultures and better fishing technology that better targets older species of fish.…

    Bluefin Tuna Effect

    Particularly, some top predators, such as groupers and Bluefin tuna can lead to changing marine communities with reduction of the great big, long lived, and high value carnivorous. Instead, the smaller, short lived, and lower value such as sardines and anchovies increase (Lubchenco). Although we do not know exactly how much Bluefin tuna are left in the ocean, we estimate the amount we caught. Some experts said, "The Atlantic Bluefin population has declined up to 85 percent from its original numbers" (Richardon). Some fishermen find and catch Bluefin because of their profits even thought some Bluefin do not become the target of catching to fatten. Bluefin are 11 ages to reproduce, and scientists believe in that (Richardon). About the environment and the other organisms, we should get a good understanding how Bluefin tuna affects. It is one of parts of the marine food web, so it is at the top and feeds on smaller fish to balance the organisms. The process of photosynthesis between plants and sun is created the energy for humans. The environment becomes too worst if ocean has no Bluefin tuna ("Overfishing: A Global Concern"). NOAA states that the mission of NOAA is to predict the changes in the Earth's environment, from the depths of the ocean to the surface of sun, and it understands how to conserve and manage the marine resources. Bluefin tuna currently do not warrant species protection under the Endanger Species Act, so NOAA needs human to realize how Bluefin tuna is important fish in the ecosystem to save them for the next generation ("Endangered Species Listing for Atlantic Bluefin Tuna not Warranted"). Because of some activities causes, Bluefin's birth is interrupted. Definitely, Bluefin tuna could disappear if we fished in the same way…

    (Miffin, 2015) In a document published by the United Nations, it states that “80 per cent of the world’s fish stocks for which assessment information is available are reported as fully exploited or overexploited and, thus, requiring effective and precautionary management.” (Overview - Convention & Related Agreements, 2010) Although varying slightly, this research is conclusive with that of The Water Brothers and supports their findings that such a large number of global fish stocks are depleted. Overfishing, when fish are caught faster than they can reproduce (Lee & Safina n.d.) has decimated marine ecosystems around the world. One of the leading contributors to overfishing is bottom trawling. This fishing technique uses weighted nets, which drag across the ocean floor, catching anything in its path. This is the most destructive method of fishing and is described by The Water Brothers, saying, “bottom trawling kills indiscriminately, ruining the bottom habitat and catching a high number of species unintentionally, known as bycatch.” Trawl fisheries for shrimp and demersal finfish account for over 50 percent of total estimated discards. (Kelleher, 2015) In addition to the bycatch from trawling, the weighted nets that drag across the sea floor destroy corals, sponges, seagrasses, and rock garden habitats. (Morgan & Chuenpagdee, 2003) By removing habitat-building organisms (source nature.com) and senselessly killing so many aquatic animals, this method of fishing has a domino affect on other species and environments. The brothers note that in addition to catching too many fish, “it also damages the entire seafloor ecosystem.” (Miffin, 2015) Like the show…

    Carl Safina, the author of Article 1 believed that management techniques should change from having a focus on ‘how much can we take?’ to ‘how much must we leave?’ This would encourage more fish to be left in the sea and help prevent the overfishing of popular species such as tuna, cod and salmon.…

    UNAM studied to know the exact terms influences the Gulf in Mexico and found surprising numbers. ln other words, almost half of the fish production is in the Gulf of Mexico. This would mean that if one day there was nothing to fish in the Gulf almost half of seafood production was scarce. Not only would that mean it would be but also many jobs would be lost. UNAM also talks about overfishing and how it affects not only the animals in the water, but also those living outside of it. "Moreover, as a result of overfishing have been observing changes in species composition, while the volume of commercially important decreases of non-trade increases. This has dramatic effects on other species, such as birds and marine mammals, which are heavily dependent on various fish stocks. " Birds, of course, also survive from fish and other things in the sea, but also may begin to feel affected by the problem of overfishing. This basically follows a chain, in a way. In my opinion, it goes as follows: As companies over fish, that affects everyone who they end up reaching as food. If there’s an overfishing at some part of the year, the other sea creatures that feed off fish, will have a lack of food for that part of the year. After that, humans who feed off the sea life will now have a lack of food as well. If there happens to be a scarcity of fish, the normal flow of fish intake will become…

    Fish Stock Assessment

    • 675 Words
    • 3 Pages

    Through this expedition, we learned how to identify the marine fish stock assessment. The fish stock assessment is a scientific analysis that tries to describe the past of current situation of a fish stock. The main objective of a fish stock assessment is to make sure that the data inputs are accurate and made in a timely matter. The results that are presented to the marine resource management are critical because it ensures how to keep sustainable fisheries, healthy ecosystems, and to have productive communities. The three inputs that are required for stock assessment are the catch, abundance, and biology. The four important methods of fish stock assessment I will examine will be: Catch per Unit Effort (CPUE), Virtual Population Analysis, Chaos theory, and lastly research surveys.…

    As stated in Overfishing.org,”We are in risk of losing a valuable food source many depend upon for social, economical or dietary reasons.” It has been a fairly recent discovery of overfishing and litterings effects on the ocean. The ocean has a very delicate and easily unsettled balance of each specie and the amount of it, which we humans, as a species are disrupting greatly due largely to overfishing. Over 75% of our Earth’s surface is covered in water and supplies us with a lot of natural resources. Some say 91% of Earth’s species live in the ocean, and say that as little as 10% of the oceans species have been discovered. Who knows how many other species we are disrupting their diets and lifestyles balance of without even knowing, besides the abundance we already know of. Drawing form eoearth.org “The worldwide problem of overfishing can be linked to several fundamental issues” one being, “ the rapid expansion of the human population is creating extraordinary demand for food in all forms;”, and because of it’s growing demand from the growing human poulation and the higher expectations from consumers to have a large variety and abundance of fish in the…

    6. How can government subsidies encourage overfishing? It is estimated that governments around the world give a total of about 30 to 40 billion dollars a year to help fishers keep their businesses running. Such money can help fishers by ships, fuel, and fishing equipment as well as for research and management of fisheries. Yet these subsidies encourage over fishing and the expansion of the fishing industry. This allows for methods to be used that cause overfishing such as trolling nets.…

    Overfishing can be a problem for both the fish and humans as well. According to Marine Conservation (1998-2010) “Foreign fishing fleets of enormous size and power from rich countries can overwhelm local people and deplete the fish stocks, causing further harm to the marine environment by disrupting the food chain. The more fish stocks become overexploited, the more fisheries must search for productive waters which are then quickly depleted (Sustainable…

    | Ongoing | In the supplied video learning resource the water resource issue that is presented is a declining big fish population. This problem finds its origins in commercial fishing and the overfishing of our oceans. A two year study was conducted by Jeremy Jackson of the Scripps Institute of Oceanography that showed 90% of big fish (swordfish and tuna) had been depleted from the ocean. A federal law was proposed to protect the oceans from overfishing but it was not approved. Jackson claims that, because fish populations are so low, 30-50% of the ocean may need to be protected from fishing in order for the populations to rebound.…
