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

    No doubt about it, pollution has been an environmental threat for a long time to our magnificent ocean and everyone knows that. In the text, “In addition to debris, the oceans are polluted by oil, sewage, and toxic chemicals,”(Dignan 14). This really proves that pollution is a part of environmental threats because oil, sewage, and toxic chemicals keep on either being purposely or accidentally dumped into the ocean which kills fish and habitats they live in. Vengeance did not come with this, but in other hands, overfishing has also been a problem in the environmental threat category. As the author stated, “...have shrunken-some drastically-as a result of overfishing or catching fish faster than they can reproduce,”(Dignan 14). This shows that overfishing is a problem because each time people overfish, down in the ocean fish can’t reproduce fast enough so less fish than before are left and other fish don’t have food then. Of course, global warming or climate change has been a huge environmental threat for a long time. Beyond that, as mentioned by NationalGeographic.com, “Global warming may lead to devastating droughts.” This illustrates that global warming also is a problem to the ocean because like National Geographic said, droughts cause less fish to appear and the ocean gets overflowed with air from humidity so it can’t get air…

    One major problem we are facing as a country is the rapid decline in several different species of fish in the ocean. Some specialist have actually looked into this to determine the cause for the decline in fish in the ocean. One of the major causes is that some species of fish are being fished more than others. It is even stated that more fish than the species are being able to actually reproduce. This alone could eventually lead some of the species into extinction. This is definitely something that can be controlled by humans. Typically, fishing period could stop any and all declines however that is not going to happen. Fishing is harder on the ocean environment then toxic pollution or degraded water quality. As human the only thing we can do if we aren’t going to stop fishing is stop targeting the same fish species to prevent extinction. We need to want to keep the environments balanced and as the primary cause of the decline fish stock in the ocean.…

    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…

    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.…

    Through commercial fishing many of the ocean and seas marine life is caught and killed unnecessarily through netting and a lot of the marine life is not consumed, but discarded, in turn depriving many other of earth’s creatures their natural food source. As an alternative to declining marine life humans have begun raising their own fish. Although fish farming can be beneficial, it can also be harmful to the environment by spreading disease and other pollutants into other waterways affecting other habitats and wildlife (Sielen). In many other ways we are affecting the decline of our oceans.…

    Also destabilized food chains, which cause over populations of some species and the decline in several others. Another problem is harming the economy, if jobs are lost due to fishing companies shutting down due to the lack of fish, then many people will lose their jobs. This results in less tax money that the government receives and growing the amount of unemployed people worldwide. Trawling vessels have progressed to now contain a large capacity of fish and have several plants to package fish into tins, reducing the time the vessels have to return to shore and maximise the time spent in the ocean collecting more fish. Fishing industries are reducing fish reproduction by capturing and killing fish who have not yet matured or reproduced, are not the proper weight, have no market value or are illegal to catch. This quickens the amount of fish unable to continue to reproduce, which then drives the specific fish specie to become endangered. They use severe methods and equipment that is non-selective to fish, that unintentionally harm habitats or catch and kill other inhabitants that are of no value to fishing companies, meaning fishing industries are injuring or killing fish with…

    (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…

    Humans have feasted on fish for as long as history can trace. The waters in which these fish are caught seem to be an overly abundant healthy environment that can relied on until the end of time, but what happens when that assumption is proved wrong? The truth is that no matter how vast and abundant the resources of our oceans may seem, we can indeed tap out the resources that our forefathers have relied on for more than thousands of years. Blue fin tuna are some of the world’s most amazing fish that roam the massive oceans, yet in recent decades, commercial fishing of these wonderful fish have caused the species’ population to spiral down at an alarming rate. Due to a large lack of regulation and ignorance to comply with quotas being set we may see the day where the beautiful blue fin tuna have been completely wiped out of our oceans.…

    By penalizing the fisherman in a harsher manner, while also banning shark fin soup across the globe, it is likely to begin the regrowth of the shark populations. As people begin to see sharks as truly magnificent creatures rather than man-eaters there is a greater chance that they will begin to understand the severity of losing the oceans shark populations. This epidemic is now in the hands of those who understand what a tragedy it will be to lose the sharks and is their job to begin a revival of shark…
