Research Paper On Bluefin Tna

1. Bluefin are warm blooded, they are the largest of the tunas, and the second largest fin in the sea

This means that they can regulate their body temperature and survive in almost any temperature of water. They live mostly in cold waters such as Newfoundland and Iceland. They spawn once a year in the warm shallow waters of the Mediterranean Sea and the Gulf of Mexico. The aggressive predator eats other bony fish and invertebrates as adults, and smaller fish such as Zooplankton while they are young. Since they are high on the food chain, they are only eaten by toothed whales, ocean sharks, and the biggest billfishes. The Atlantic Bluefin Tuna travel to warmer waters to procreate once a year. According to panda.org, female tuna can produce up to 10 million eggs per year, but only a few survive. The average lifespan of the tuna is 15 years, unless they fall victim to

It is not educational. Teaching adults and children to dump five tonnes of critically endangered southern Bluefin tuna into cage should not be considered as educational [2, Pge 1]. Since the tuna are going to be handfed and constantly in contact with humans they will not display

And the web hosting companies now need more than just price to differentiate themselves from the rest of the pack. One company with great history and experience is Bluehost Web Hosting.

The allusive bluefin tuna is one of the largest, fastest and highly sought after fish in the wild sea. The Bluefin tuna can weigh over half a ton, grow to over four metres in length, and dive to depths of 1,000 metres. They can reach speeds of 70 miles an hour and even raise their body temperature far above that of the surrounding water in order to traverse arctic waters. They are among the most ambitiously migratory of all fish, with some tagged bluefin being tracked swimming from North American to European waters several times a year. The bluefin tuna is unique, a perfectly adapted products of evolution. They are also dangerously close to becoming extinct (Brown). Today, the bluefin tuna has been fished out by 97 percent from pre-fishing

Do you really know what you're feeding your cat or dog ? have u ever really looked at the ingredients and not just the cute packaging ? We treat our pets like family and you want to feed them the best that's why you should feed your cat or dog blue buffalo. Most cats and dogs are not getting the nutrition they need from their average cat or dog food. A lot of the products contain things that don't benefit them in any way.

Tuna that go by the scientific name of Thunnus Maccoyii (Dennis. M et.al, 2010) are one of the most valuable finfish cultured within Australian and most sought after for sushi within Japan. The waters generally out from Port Lincoln within Spencer Gulf, South Australia are where the tuna are mainly cultured in Australia due to the water temperature being ideal for the culture of these highly valued finfish. Tuna is within the top four of the most valuable cultured aquatic species in Australia especially Southern Bluefin Tuna (SBT) which are valued at four hundred dollars per fish making the transport and capture of these fish very important where damage is avoided at all costs. The transport of the captured fish from the wild in nets back into shallower water where they can then participate in the ranching stage can lead to serious problems and can bring upon mortalities if done incorrectly. Ranching is the process of temporally holding wild fish at sea to fatten them on baitfish. (Kirchoff. N et. al 2011 pg1) This process of transportation from the wild back into the grow out pontoons or cages for ranching can lead to effects on a fish’s health, performance and or even disease and parasite infection.

One of the distinct features of any common resource is that it is a “non-excludable good1”, meaning no one can be prevented from using what is available. As discussed, the consequence of this scenario is that it will produce a socially inefficient outcome. There are differing theories on how to achieve an economically feasible marginal cost and marginal social benefit equilibrium. The difficulty, of course, is to determine what the socially optimal supply level for Bluefin Tuna should be in relation to fish stock restoration and future sustainability as well as empowering the global community to act in unison. The discussion here

“A single Pacific bluefin tuna sells at auction for more than $100,000” (Arnold, 2012). The Pacific bluefin tuna is one of the most popular fish consumed in the world eaten mainly in sushi. In 2010 alone, the United States consumed twenty-four percent of the tuna consumed by the entire population. Due to its increasing growth in popularity the demand for wild bluefin tuna has caused the species to drastically decline to about 2 percent of its original percent population causing it to become endangered. Due to the drop in the amount of wild bluefin tuna left there have been serious changes to the ocean’s ecosystem. The Pacific blue fin tuna is one of the top predators in the pacific oceans food chain making it a tertiary consumer. For them to survive it must feed on the Ocean’s secondary consumers which are the anchovies, herring, etc.

Bluefin Tuna are so popular, that one man in japan bought one of the fish at an aution for over 35,000 dollars! He aparently bought one just two years prior for over a million dollars (Graif). Japan is also the leading Bluefin Tuna fishing country, with over 80 percent of the bluefin fishing market in its pocket (Smith). Think of how much its economy must rely on the Bluefin! In 2010, Japan even refused to join in on the ban on international trading of the Bluefin, thus ignoring the ban altogether (Jolly). Japan is also the leading importer of fish, making over 14 billion dollars with just importing fish

Blue whales used to be very copious in all of the main oceans in the world until around the 18-20th century when many of the began to be killed off. They were mainly killed off so their large amounts of blubber and meat, which was used to make raw materials and products. These mammals can still be seen swimming in many oceans, like the Atlantic Ocean, Pacific Ocean, and even the Antarctic Ocean, the numbers of blue whales have gone down, which has slowly made them to be seen as endangered species. However, during spring/summer they have the tendency to migrate to the Arctic Ocean. Blue whales spend their lives in different oceans in the world.

Since I was young, I have always had a busy schedule. With school and two sports, I rarely have quality time with my family. But all that changes when summer break rolls around, and my family goes on adventurous trips. On every single trip my family and I have had a great bonding experience and it gets better each year. Every summer has been exciting and has led me to travel to all 50 states. All of these experiences have helped me to appreciate and bond with my family.

Sharks, varying in size, are widely located around the world. The longest shark, the Whale Shark, spans 60 feet long and can weigh up to 70 tons. These sharks are not dangerous to humans because they are filter feeders. Usually, a female shark gives birth to around 10 pups at a time. While she nurses the pups, she keeps them in the shallow water to protect them from male sharks who eat baby pups. Sharks are generally not friendly to humans. They can detect one sole drop of blood in more than a million gallons of water. ⅔ of the shark's brain is given over to interpreting blood. Once they smell the blood, the sharks go into a crazy frenzy, where their teeth are pushed out and jaws open wide. The great white shark is probably the most deadly

Throughout the research the most useful source was, Population Dynamics of Western Atlantic Bluefin Tuna: Modeling the Impacts of Fishing using Differential Equations. The source was the most useful because of the connections that was shown between population models and mathematics. The reliability was judged to be high because of the authors Esther Bowen, Marie Hoerner, and Cassie Kontur. The information stated was backed up by other sources and judged to be accurate. Lastly the information displayed was up to date and on topic.

Blue belongs to the bright colored fish species commonly known as betta or also as the Siamese fighting fish. Originally from Southeast Asia, this particular species of fish is known as a labyrinth because it is able to breathe in oxygen directly from the surface. In addition it can survive out of water, for a short period of time, as long as it is moist (The Beauty of the Betta). Their lifespan ranges from one to four years. Although betta fish are seen as a house pet, they originally reside in the Mekong River (Siamese Fighting Fish). Known for their feisty temper, the betta fish's’ diet consist of all meat such as brine shrimp and insects (Siamese Fighting Fish).
