Overfishing: Fish and Marine Ecosystem

Catching A Little Too Many? Do you ever go out to eat some seafood and see the fish that is served? Have you ever thought about the abundance; how much fish there is? And have you ever thought about there being a shortage a fish; seems impossible, right? Because when we think of fish, we think of the millions or even billions of little or big swimming creatures in the huge ocean; how could there be a shortage? Overfishing is the answer. Overfishing is where we hunt fish faster than they can be replaced naturally; which causes the number to abate very quickly. People do not believe overfishing is a problem because it is not something you can easily see, unlike global warming. Global warming has visual evidence like melting snow and warming temperatures. Only fishermen are able to see the obvious subside, but they need to fish to sustain restaurants, stores and other businesses. Since no one owns the fish in the ocean, it is a goal to catch as many fish as possible as fast as they can. Due to that action, it is also hard to find storage for the fish causing the fish to spoil. This means fish that we are catching, isn’t even being used. Fishing is a big part of the ecosystem, the food chain, and the economy. We are losing many species of fish as well as entire ecosystems. Although fish is common, we need to be careful on the amounts we take. It is time for us to take action and hear out a worldwide problem. A question is how much fish has the world lost? At an average, 120 million tons of fish are caught annually, and 1.3 million tons are being wasted. According to an article by Mackenzie Yang, 200 billion pounds of seafood and 54 billion pounds of non-commercially valuable marine life are being ensnared in fishing nets as long as a football field. Not all of it is even used. Also, according to Mackenzie Yang, large predatory fish like tuna have decreased by ninety percent worldwide during the last

    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.…

    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.…

    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.…

    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.…

    The constant improvements in fishing technology and equipment has allowed knowledge of the main migration routes of the tuna, and so very effective fishing, and in the last 60 years marine conservationists have seen the population of the southern Bluefin Tuna drop by 92% [2]. This significant decline in the worldwide stocks of this tuna has led to the International Union for Conservation of Nature (IUCN) placing the Bluefin tuna on the critically endangered list and Greenpeace also added the fish onto their seafood red list [3]. This means that they recognise the fish is being overfished and the…

    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…

    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.…

    (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…
