Bluefin Tuna Effect
Some around the world enjoy eating a lot of food; they try to discover some new food from the different countries. Sushi is one kind of food to make people like to eat; it is a famous food in Japan and around the world: America, China, and the others. Sushi has some ingredients: rice, seaweed sheets, seafood, vegetables, and tropical fruit sauce. However Bluefin tuna sushi is the best to make some like the most. As a result, at this time some want to have more Bluefin tuna so that over ten hundred of thousand dollars people can buy a Bluefin tuna (Richardson). Since the high demand and price have stimulated, some fishermen work hard to catch more and more Bluefin. What is the happening? The overall ecosystem and economy the world are influenced …show more content…
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.…

    The most significant difference between the reproduction of humans and the bluefin tuna is that humans reproduce internally and tunas reproduce externally. In humans, their reproduction consists of sexual intercourse where the male sex organ is inserted into the female sex organ. During this process sperm from the male swim and fertilise the egg within the females. In the Bluefin tuna, both genders of fish release a substantial amount of sex cells into the ocean in order to produce the eggs. In addition, the Bluefin tuna lays eggs and humans give birth to live young. Another comparison is the variation in the feeding processes of the embryos. Within the fish eggs there is yolk, the yolk is the food supply for the tunas up until a few days…

    There was once a time where the oceans were pure and fish were plentiful. However, that was quite some time ago. Today, the oceans are filthy and filled with more toxins than fish. It is strange to think that since the 1950s, the birth of commercial fishing, that our oceans have almost been completely destroyed. Through industry-based fishing, whole ecosystems have been almost completely devastated; several species that have once been abundant have now been placed on the endangered species list. If commercial fishing is not subdued within the next couple of years, then the potential collapse of commercial fishing, and our ocean’s ecosystems, will be upon us.…

    One of the additional problems caused by overfishing is diminished food supply for animals and humans. This hurts the marine ecosystem of oceans and seas all around the globe, which in turn directly impacts human nutrition. Overfishing has increased greatly over the past decade (Nuttal 1). According to the Food and Agriculture Organization, "over 70% of the world 's fish species are either fully exploited or depleted" (Nuttal 1). This problem will continue if people around the world do not change their ways soon to prevent extinction of all of the fish in our planet 's waters. Overfishing of the world 's oceans is rapidly destroying sea life, all of which act as renewable natural resources. As a result, the destruction of such natural resources negatively impacts the quality of…

    In this report, I will explain how the overfishing of sharks has an effect on marine ecosystems. Also, I will be touching on the dangers to sharks worldwide and the catastrophic impacts that the mass depopulation of sharks could have on both animals and humans. Overall, sharks worldwide are in danger due to the fact that as many as 100 million sharks are killed each year. This has devastating effects on marine ecosystems due to the fact that sharks help to maintain a balance in marine ecosystems and have done so for some 400 million years. Also, as they are the apex predators of the oceans, much like wolves or lions on land, they help to stop some species from over populating an area. If sharks are almost completely removed from an ecosystem there is a boom in the population of the prey of those sharks, for example cow nose rays. Then, the population of these rays ‘explodes’ causing there to be many more rays in the ecosystem than nature intended. Resulting, in a rapid decline of the animals that these rays feed on, for example clams and oysters. Then, the rays begin to run out of viable prey and so the exploded ray population begins to decline until the once diverse and functional ecosystem has been completely destroyed.…

    Japan’s Fukushima Nuclear Power Facility is leaking into the Pacific Ocean constantly. This leak was caused by a powerful earthquake in 2011. Any sort of chemical leak is terrible; however, the location of the Fukushima facility makes it significantly worse. Because this body of water does not remove or clean itself well, the chemical pollution is just increasing and taking over the ocean. Marine life is being severely affected by this. One fish that should be a main focus is the West Coast Blue Fin Tuna. The West Coast Blue Fin Tuna is a widely recognized fish and the West Coast Tuna Fishing industry is very familiar with this marine life form. For this industry, the Fukushima leak is the worst possible event. Phytoplankton, plankton, and many other marine life forms feed on the radioactive chemicals being released by the gallons every day. This consumption of chemicals makes its way up the food chain to the West Coast Blue Fin Tuna. Not only is it now harmful to eat, the West Coast Blue Fin Tuna ingests the radioactive chemicals which in turn begin to eat away at its tissue thus leading the…
