Recommended: Shark decline and its effects

Researchers from the Future of Marine Animal Populations (FMAP) project of the Census of Marine Life have conducted an analysis of shark population data for the Northwest Atlantic Ocean in relation of mesopredators, which are the next species in the food chain such as rays, skates, and smaller sharks and the decline of commercially relevant shellfish supplies. This study explained how the decreasing populations of the eleven different shark species in the Northwest Atlantic, the apex predators, have affected the lower trophic levels of the ecosystem. The study found that the as the shark populations decreased over the span of thirty years, the populations of twelve of the fourteen species of the prey species associated with these sharks have

    Seaworld is a giant marine life theme park. The greatest attraction to these many theme park would be those killer whales. In fact, these killer whales are the face of the park. As gigant as these mammals are, seaworld is keeping them in some pretty tight quarters. Mr. Jett and Mr.Ventre says “Wild killer whales can swim a hundred miles daily as they socialize, forage, communicate, and breed. In stark contrast, with little horizontal or vertical space in their enclosures, captive orcas swim only limited distances, with most spending many hours surface resting.” The animals don't have the freedom they need. Also when taking the whales out of their natural habit the whales tend to be depressed and not as heath in that situation. They need their freedom in the big ocean blue. Bring them into the small living units, breeding whales in captivity all for the entertainment of humans. At young ages the calves are taken away from their mothers on to a new seaworld park. Mothers of the calves have even been seen denying their offspring.

    In this entertaining, search into global fish hatcheries, New York Times writer Paul Greenberg investigates our historical connection with the ever changing ocean and the wild fish within it. In the beginning of the book Paul is telling his childhood fishing stories to his friends, that night Paul discovers that that four fish dominate the world’s seafood markets in which are salmon, tuna, cod, and bass. He tries to figure out why this is and the only logical answer he could come up with is that four epochal shifts caused theses wild fish population to diminish. History shows that four epochal shifts happen within fifteen years causing certain fish species populations to diminish. He discovers for each of the four fish why this happened to

  • Shark Culling should be abolished in Western Australia

    So why do we need sharks? Well, Sharks help keep the ocean healthy and clean for over 450 million years. They also help remove half of the worlds green house gases and produces oxygen more than all of the rainforest's combined! Sharks are just as important as all the trees in the world because they have one thing in common, provide us with oxygen. Without the sharks help we wouldn't be able to get rid as much of the greenhouse gases as we want to, which means global warming would have a lower rate of happening faster. Most importantly they provide us with food. How? They would usually eat the old, sick or slower fish in the population of the ocean to the right size so the prey species don't cause harm to ecosystem by becoming to populated. They are also at the top of the food web. If all the sharks went extinct the entire food web would collapse causing many other species of fish to disappear. So instead of killing the sharks, we could lure them away to somewhere else. As they have a huge impact to the environment.

  • Newfoundland and Labrador's Cod Collapse

    1118 Words  | 3 Pages

    Over the years, as the world has evolved, fishing methods were improved as well, and, especially from the 20th century, several changes had forced the way the fishery was done in North Atlantic. As world population was increasing quickly, the cod demand has grown tremendously. New technologies were introduced and thus catch rates of northern cod began to exceed the hazardous limits of the stock’s ability to rebuild. This fact summed with another that will be shown below led to the cod collapse in the Atlantic Canada by the 90’s.

  • Brief Summary: The Collapse Of Shark Water

    685 Words  | 2 Pages

    As I mentioned earlier, Sharks maintain the balance of the entire marine ecosystem! If the ocean’s ecosystem were to collapse, it would greatly affect life even on the surface. Sharks tend to eat fish who are much slower and sickly therefore they keep the population of fish in a healthier state. We depend on the oceans for the oxygen that we breathe because of certain species in the ocean that produce oxygen such as Phytoplankton, if Sharks were to be extinct, we would lose a great amount of the oxygen on Earth because the balance of living Phytoplankton and other species would not be enough. Furthermore, Sharks have been maintaining the balance of our ecosystem for 400 million years, if these sharks were to be gone, who would balance this heavy task? A number of scientific studies demonstrate that depletion of Sharks results in the loss of important fish and shellfish species from the food chain, including key fisheries such as tuna, which help the health o...

    One of the governments main reasons for culling the sharks is because they are coming in too close to the shores and becoming a potential threat to swimmers. But why is this happening? This is due to a change in shark feeding habits, but because they are eating more human of course not! Rather because us humans are over fishing and eliminating the fish/food sources of which sharks normally feed on. This is forcing sharks to come in closer to find food. Us as humans have forced sharks to come in closer and are now killing sharks because of our a...

  • Essay On Canada's Fishing Industry

    1832 Words  | 4 Pages

    With a coastline of over 202 000 km and over a fourth of the world’s freshwater resources, it is no wonder why Canada’s fishing industry is a huge part of its economy.1 Canada exports more than 75% of its fish to over 130 countries worldwide. Many of the 7 million people who reside on the coast depend on the ocean’s resources. In total, Canada’s entire fishing industry is worth around 5$ billion dollars a year, being one of the world’s most valuable. However, the coasts have not been treated by respect; overfishing, over consumption, and wasteful practices has deteriorated, not only the industry, but the ecosystems and fish populations. This is a huge global issue; the worldwide collapse of fisheries has been project for 2048. Slowly, as the trends continue, we will inevitably see many fish species start to disappear. In fact, the ill-treatment of species on the Canadian border has already devastated a large specie, the cod.

    Bottlenose dolphins became part of a United States Navy program in 1959 for the purpose of conducting scientific research into their sonar and hydrodynamics in hopes of getting design ideas for submarines, ship hulls and weapons. It was discovered dolphins hear and navigate in the water by using their natural sonar, which happened to be more precise than most fabricated sonar systems. In the mid-sixties, Navy dolphins were used as mail carriers to underwater laboratories in their home of San Diego, California.

  • Sharks: Great White Sharks

    1577 Words  | 4 Pages

    In 2015 only 59 shark attacks have occurred around the world compared to the millions of sharks killed by humans every year. Due to these accidental shark attacks people tend to think that sharks, especially Great Whites are evil creatures with malice intentions when attacks do occur; but, on the contrary that is wrong. Sharks are not the only beautiful and unique creatures in the ocean, they also play a vital role in our ecosystem; however, due to human interference they might not be around much longer, through awareness sharks can be protected from endangerment.

  • Ocean Protection and Conservation

    1961 Words  | 4 Pages

    The oceans need to be protected because it is where life began and if not taken care of, life as we know it will end. When dangerous substances go into the ocean, ecosystems are suffer and become endangered along with lives of people and of marine life. Surfrider Foundation recognizes the importance of protecting and preserving the quality and biodiversity of the world's coasts because they are truly irreplaceable. There is also historical evidence of ocean pollution being present in the past, but the problem still lingers today. Heal the Bay discovered that,“Did you know there is a DDT and PCB hot spot off the coast of Palos Verdes? This superfund site (which indicates it's one of the most polluted places in the United States), is left over from a 1930's era chemical plant. Because DDT takes so long to break down in the marine environment, it persists to this day, contaminating certain species of fish. There are also highly polluted sediments in the Long Beach area, a sign of the heavy shipping in the port. Heal the Bay works on developing effective capping and removal plans to keep those toxins from spreading” (Heal the Bay). DDT is still highly concentrated in the South Bay area and still contaminating different species of fish. Even after more than 80 years DDT, a toxic insecticide, is still very concentrated and during upwellings, DDT particles come back up and continue to harm marine life. If humans are careless about what is thrown on the floor or sprayed on lawns, it can lead to disastrous affects when it comes to the condition of the ocean's ecosystems, and can endanger life itself leading to a problem that only we can mend.
