Mariculture Essays - Aquaculture, Fisheries, Mariculture, Oyster

Mariculture Mariculture As the Spanish entered the capital city of Tenochtitlan they were astounded at the many marvels of the city but one of the things that most caught the eyes of the foreigners was the extensive plant growth on the lake surrounding the city. These images were describe the among the first recorded descriptions of large scale mariculture. Mariculture, or aquaculture, refers to the rearing of the aquatic organisms under controlled or semicontrolled conditions. Although there is a simple difference between the two, aquaculture generally refers to the exploitation of freshwater fish and mariculture more generally refers to the culture and farming of marine organisms. Simply put mariculture is underwater agriculture. There are many possibilities for the realm of mariculture, it has the potential to be a great help in the production of the food supply in the world. Mariculture is not a new development in mankinds history but it is a largely ignored form of food production. In a broad sense mariculture includes the rearing of tropical fishes, the production of minnows, koi, and goldfish; the culture of sport fishes for stocking into farm ponds, streams, reservoirs, and even the ocean; production of animals for augmenting commercial marine fisheries; and the growth of aquatic plants. Mariculture is a myriad of possibilities that involve organisms and the seas. The history of mariculture can be traced back way into the past, the Greeks and Romans were known to have fattened fish in ponds and Egyptian carvings suggest that the Egyptians may have practiced it as well. So we know that the potential for the exploitation has been there for a very long time. Why then has this type of food procurement not been used more extensively? There can be a few good reasons for this such as the availability of technologies, the difficulty of harvesting the seas, and the knowledge of the workings of the sea in order to fully use the capabilities of the ocean. We now have the technology, knowledge, and capability to successfully implement large scale mariculture. Historians say that agriculture made it possible for man to grow and expand as it has done over the last few thousand years so now one can wonder what the future holds if and when mariculture is implemented into the everyday workings of society. Could it be the next giant leap for mankind? There are many different methods to mariculture. For the most part mariculture entails the confinement of fish to earth ponds, concrete pools, or cages suspended in open water. In these enclosures, the fish can be supplied with adequate food and protected from natural predators. Some of the most common methods for mariculture are transplantation, hatchery stocking, and enclosures and retainers. Transplantation involves the movement of fish populations from a good fishing area to a location that does not exhibit a great fishing catches. In this way areas of low fish concentration are injected with an influx of fish that help to make the average much higher and thereby bring the overall population to a higher state. The next method of mariculture is hatchery stocking this process happens when people create a safe environment such as tanks, pools, or concrete or earth ponds into which they pour fish eggs. These eggs are cared for and are provided with the essential things such as nutrients and correct temperatures in which to thrive. The fish are born and raised to a certain stage and then are moved to open waters or such places as lakes, streams, and ponds. In this way these habitats are provided with ample supplies of fish and other marine organisms. Another method involves the use of enclosures and retainers. This certain method can be described in three separate ways, natural feed, supplemental feed, and no natural feed. The natural feed method works by separating the desired fish and the food providers of the fish from there predators in there own natural waters by the use of netted embayments and cages, thereby allowing the provider to grow and multiply in its own habitat and this in turn a llows the fish to multiply. The second way is supplemental feed and this method works by isolating fish in tanks or concrete ponds. In

Essay Sample on the Persian Gulf War

Essay Sample on the Persian Gulf War Free sample essay on The Persian Gulf War: The Persian Gulf War, also known to Americans a Operation Desert storm, was one of the most defining events in American history. It was the one war that Americans fought in and had very little loss of life! Said mother when I asked her about the war and what she thought of it. And that was very true since almost all of the 500,000 troops sent into Kuwait came home safe and sound. This war was also one of technological superiority which greatly favored American forces. The use of guided bombs, missiles and almost invisible planes made it easy for the American forces to take out key targets on the Iraqi battle ground. The war began because the Iraqi dictator Saddam Hussain believed that Kuwait was over producing oil and that they stole oil form other oil fields. This quickly escalated to an all out war and had the oil-thirsty man Saddam and his troops stormed into Kuwait with guns in hand and thoughts of destruction and greed on their minds. This upset American president George Bush who immediately gave a call to congress to act against this devilish crook who struck fear into the eyes of his enemies and his own suffering people. Congress agreed and Bush sent in 500,000 men to fight for the liberation of Kuwait and its valued natural recourse. Stealth bombers, F-15 fighter jets, and B-2 bombers bombarded the Kuwaiti soil demolishing any and all Iraqi military targets and clearing a path for the American clean up crew, who with great ease took out any remaining resistance. The Persian Gulf War though short gave new self pride and honor to American people said my father after reflecting on the wars outcome. And that is so true, because today American people stand proud next to their leader knowing that he will serve his country and his countries people to the fullest of his abilities. Giving us a safe home and a powerful, capable army to support us and rush blindly into battle to protect the country they so love and care for. This is what makes this country the greatest country on earth and is still being proven today on the battle grounds of Iraq. Where men and women fight side by side for the greater good and to defend the innocent of the world.

Australian Economy Essay Example | Topics and Well Written Essays - 2000 words

Australian Economy - Essay Example The prediction was that the central bank of Australia would be forced to bring into play an expansionary monetary policy that would have rates of interest lowered to 2.5% from 4.25% so as to trigger growth. (Foley, 2009) Just before looking at this policy, it is of essence to explain vividly what a monetary policy entails. The situation in the world since year 2008 has been very serious and many economies including North America and Europe experienced a major economic downturn. Generally, the whole world was experiencing one of the most serious economic recessions. Australia as an economy has been said by most economic analysts to have defied this downturn. However, it has been affected as well by this situation, to mention the least. Governments, through their central banks, use both monetary policies and fiscal policies to control the stability and growth of the aggregate economy. This study is about both of these economic policies and more particularly in the context of the Austra lian economy. The study will first tackle each of these policies in general to create an understanding of the same before narrowing down to the Australian situation. Monetary policy will be the first to handle before going on to the fiscal policy. Monetary policies are usually about two major categories. These are expansionary and contractionary monetary policies. An expansionary policy is generally an open-market buying while a contractinary policy is about an open-market sale. An expansionary policy involves lowering of rates of interest while a contractionary policy escalates interest rates. Increased interest rates (contractionary policy) mean that borrowing from banks will be more expensive and thus, there will be minimal borrowing, which reduces currency supply in a given economy. A reduction in interest rates (expansionary policy) means that borrowing from banks will be easier due to the low rates of interest. Thus, this increases currency supply in the economy. Graphs can be utilised to illustrate what has been explained earlier concerning monetary policies. This is as shown below; Figure 1: Monetary policies illustrated in graphs Interest rates S0 S1 Interest rates S1 S0 D D Bank Reserves Bank Reserves Expansionary policy Contractionary policy As shown by the arrows, an expansionary policy involves a lowering of the rates of interest and thus, a rise in the supply of currency while a contractionary policy does exactly the opposite. S0 shows the original currency supply while S1 is the new supply. D is the demand curve for currency. (Baumol and Blinder, 2010 pp270, 271) Despite the criticism by the International Monetary Fund, that Australia was using a bad approach (in year 2010) to the inflation levels by using a monetary policy that was based in inflation targeting, the Reserve Bank of Australia continued using this approach. At this point in time, the bank was applying a contarctionary policy. The Reserve Bank usually targets a range of inflation o f around 2-3% while making these decisions of the monetary policy. It was to utilize the rates of interest so as to slower the overheating of the Australian economy. In 2010, the inflation target ranged between 1-2%. In order to control the condition of the recession effects, the Reserve Bank was applying a

International relations - foreign policy Essay Example | Topics and Well Written Essays - 1500 words

International relations - foreign policy - Essay Example Countries, big and small alike, have internal domestic policies. Concurrently, they also have foreign policies. These policies are bases of the values and interests that are crucial in guiding how these particular governments act or behave with regards to certain international issues. Policy, here referring to a certain course of actionAccording to Feigert, Graebner, Papademetriou, Mangone, Ransom, Wilson, Wolfe, Piper & Terchek, foreign policy is the foreign component of public policy. (1983) Simply defined, public policy is the choice or the stance that particular governments adopt with regards to certain issues in country. (Dye, 1972) That said, while public policy is concerned with the domestic issues and policies to be implemented within (inside) state borders, foreign policy on its part is concerned with policies that are to be implemented without (outside) the countries borders. (Feigert, et al, 1983) Foreign policy plainly put is the policy that is formulated and adopted by s tate governments for the purposes of governing its relations with other countries in the international arena. The most important thing to note about foreign policy is that it is primarily concerned with state interests. State interest could be in either, political, military and/or economic terms. The reason why a country would like to implement certain policies with regards to other countries has to do with what it stands to gain more than anything else. Shah (2001) posits that every nation/country is in possession of a foreign policy. The reason why foreign policy is important is because it ensures that the needs of the nations/countries are represented in the international community. During the cold war countries mostly used foreign policies as a way of furthering their national interests and agendas. In the course of furthering these agendas, the interests held dear by other nations in the international community did not matter much and were disregarded. In most cases this often led to resentment between different countries with different issues to push forth. (Shah, 2001) The conduct of foreign policy then involves balancing between substitute policies and their perceived costs and benefits. (Feigert, et al, 1983) At the end of the day, countries more often than not, adopt the policies that are most favorable to them and are in sync with what they may want to achieve (national interest). It could be security needs or economic growth. (Shah, 2001) Traditionally, the conduct of foreign policy has often been the duty of the national governments. Nonetheless, other actors within the state realm are involved in the conduct and formulation of foreign policy. These are the smaller regional states and provinces within a nation/country. For this reason, there is always advocacy and lobbying for the type of issues and interests that should be part of foreign policy and which respective government should focus on. This way these state actors are able to influence foreign policy decisions. Despite this, some governments wield such immense powers such that they lo ck out these state actors such as regional states and provinces out of the formulation and consequent conduct of foreign policy. Take the case of India for example. As per the Indian constitution, the central federal government, the executive, is granted all the powers in the land necessary for the conduct of both domestic and foreign policies. Still, even though these actors are given lesser powers, but powers nonetheless by the Indian Constitution, the regional states in India have little or no autonomy. The consequence of this is that their roles are usurped and the central government makes all the crucial decisions with regards to foreign policy. (Dossani & Vijaykumar, 2005) As countries conduct foreign policy they involve themselves in such activities as diplomacy, negotiations, bargaining, cooperation or even coercion, bullying, lying and intimidation. Depending on what their interests are at the end of the d

Harry Potter and the Sorcerer’s Stone Essay Example for Free

Harry Potter and the Sorcerer’s Stone Essay Ever since the first printing of the first Harry Potter novel, the book series has been under attack from people arguing that the books are intended to initiate children into witchcraft and demonic practices or that they undermine traditional spiritual values. Yes, indeed, there are ghosts and Halloween, and the practice of magic. However, Harry Potter books are no more a threat to the traditional spiritual values of our children than The Wizard of Oz was before them. Harry Potter has not grown up in a â€Å"normal† family, even outside of the wizarding world. The Dursleys do not care for Harry and treat him poorly. They are clearly nominally Christians; in Chapter Two, Harry’s uncle threatens him with punishment, saying that Harry will â€Å"be in that cupboard from now until Christmas† if he is involved in any â€Å"funny business† (24). There is no evidence, however, that the Dursleys ever practice any particular faith. That lack of spiritual practice carries through the book, even in the wizarding world. .While no one falls to his or her knees in religious fervor, neither does anyone sacrifice a goat to Satan. Rowling has kept her books carefully neutral, but not because she wishes to undermine traditional spiritual values. Rather, it seems that Rowling wishes to appeal to the largest possible audience, without appealing to one spiritual belief over another. Rowling presents Halloween in such a manner that would appeal to the imagination of children, with bats, candles in pumpkins, and a feast; however, it is also merely a backdrop for the action that brings the Three Musketeers of Harry, Ron, and Hermione together (Rowling 172-179). Later in the book, the characters celebrate Christmas. Christmas, however, is no different from Halloween. The Christmas break serves only to give Harry a quiet moment to investigate the library and to investigate the Mirror of Erised (Rowling 204-209). Once again Rowling is carefully neutral, describing Christmas only in terms of what would appeal to children. While Rowling focuses primarily on food, gifts, and games, Ron’s brother George also takes the time to tell another brother that he will not be sitting with his fellow prefects, because â€Å"Christmas is a time for family† (203). Rather than glorifying the wizarding world, Rowling chooses to show that the wizarding world is no more appealing than the Muggle world. There are still bullies there: Draco Malfoy is just like Harry’s cousin, only he is thinner and can ride a broom. Friendship and loyalty and knowledge are all valued there; fellowship and fun are as much a part of the school as magic is. Harry Potter and the Sorcerer’s Stone is simply a fantasy story about a boy and his friends away at boarding school. The only real magic connected to this book is that it rekindled many children’s interest in reading. Who can truly argue with that result?

Tony Kronheiser :: essays research papers

Tony Kronheiser Tony Kornheiser is the self-admitted opinionated, sarcastic sports and style columnist for The Washington Post. Kornheiser's purpose is not to report to the reader an objective account of a sporting event, but rather to add humor to topics that range in topic from the Washington Redskins ("It's Now an Off-Road Vehicle," November 5, 1996) to his lunch-time experience the other day ("In a Real Fix," November 3, 1996). Kornheiser's diction, figurative language, and tone make his columns what they are. Often, diction, figurative language, and tone are not common in the journalistic world, but Kornheiser's humor finds room for them. Tony Kornheiser's sarcasm is almost entirely related to his diction. He contains the skills to take something as insignificant as a restaurant changing on him unexpectedly and reports about it so that the common man can relate. He is The Washington Post's Jerry Seinfeld. He blends the slang of the street man with the poetic verbs and fluid adjectives of an English teacher. For example, in "In A Real Fixe," Kornheiser says, "George was beginning to suspect that we had entered (doo-doo, doo-doo). . . The Nouvelle Dining Zone." Most people who have watched the Twilight Zone before can relate this statement as a reference to the famous TV show, so Kornheiser's slang was effective in grabbing the reader, even if a large majority of them have no idea what the word "nouvelle" means. Kornheiser uses an array of such adjectives throughout his pieces but he does not pretend to be above his readers. He fills his work with colloquial speech such as his references in "It's Now an Off-Road Vehicle" to other Washington Post columnists such as Michael Wilbon, and to his "Redskins Bandwagon." (The Redskins Bandwagon was a common phrase used by Washington Redskins fans when the team won the Superbowl in 1991). Kornheiser assumes that the reader is familiar with him, and that is clear in his informal diction that is used with the reader. It is almost to the point of a friendship, as though a coworker was letting off his steam at work during a lunch break. Kornheiser's figurative speech also add to his style quite well. The blend of diction and figurative speech is clear as Kornheiser uses several local allusions in his metaphors and similes that add to his "common man" image. For example, in "In a Real Fixe," Kornheiser compares the look of a hostess' face to one of a nurse at St. Elizabeth's, a local mental hospital. In that same article he also compares his whole experience to "going down into the Metro and

Religion and Science Essay

They can actually complement each other. To understand what Einstein meant when he said this, we must first understand his views on religion. When I was first given Einstein’s article â€Å"Religion and Science† in class, I felt like he was very anti-religious. Throughout the first few paragraphs of the article he talked about why people were led to religious thought and belief. According to him, it was fear and the desire for guidance, support, and love – emotions that were considered signs of â€Å"weakness† – that evoked religious notions. It was just this that drove people to look into a higher being as a means of hope. These feelings are what initiated religious beliefs that told people what they can and can’t do to please God. Einstein’s belief that these â€Å"weak† feelings initiated religion, made him seem so opposed to the idea of looking into an unknown being as a sense of security. Later on in his article, Einstein also told us that religion is not necessary for a person’s ethical behavior. You don’t need a God to tell you right from wrong. After reading all of this, I came to the conclusion that Einstein did not believe in religion. However, after further reading on Einstein I realized that I was very much wrong. Einstein did believe in a religion, but his religion was not the typical, traditional, organized religion like most people believe in. Einstein believed in a â€Å"cosmic religious feeling;† he believed in a higher being that controlled the universe, but not one who was interested in the personal affairs of humans. It was his line of work that had become his religion. He was so passionate and devoted to science that it had become his faith. His religious feeling was of â€Å"inklings† and â€Å"wondering. His religion was his thoughts, and it was through this that Einstein studied and came to scientific conclusions. Einstein’s religion was his questions, and science was his means of getting the answers. Einstein once said that you are not a true scientist if you don’t approach science with religious awe. Einstein believed that science and religion were nothing without each o ther. Since religion was Einstein’s â€Å"inklings† and â€Å"wondering,† religion was a sort of motivation for science. After all, what would science be without human questioning? Science would be pointless without religion, and that is what Einstein meant when he said â€Å"Science without religion is lame. † Science is just, as many people see it, a search for answers, and religion gives the questions. Some people choose to follow a religion without any logical thinking of their own; this is what Einstein meant by â€Å"Religion without science is blind. † It doesn’t make sense to believe in something without any logical reasoning. You would have to do some further research and study to give yourself further knowledge and understanding of a certain belief. Many people believe in a certain religion just because their parents believe in it, and that is the faith they grew up in to. They practice this religion because it’s what they were taught to do, not because it’s something they personally believe in. This is an example of a religious belief being â€Å"blind. † The person hasn’t looked into the religion at all on their own to see if there is any truth in it. They believe it just because their family believes it. This is completely illogical. Without proven facts to back up a belief, the belief is simply blind. A belief being blind, meaning that the belief has no evidence to back it up. There is no logical reason to believe in it. Science helps to create an open minded understanding of religion. Without science, religion would be useless and completely illogical. Although religion is not the same to me as it was to Einstein, I completely agree that religion and science are nothing without each other. Religion and science go hand in hand. My religion, Islam, doesn’t only tell me to believe, but it also provokes me to ask questions. Unlike Einstein, my religion is not just a religion of questions, it gives answers as well. However, most of these answers can be scientifically backed up, and the others have not been scientifically disproven either. Religion, or more specifically, Islam, is not primarily scientific; however it does answer some of the same questions as science. I believe that religion is nothing without science because it doesn’t make sense to blindly believe in something without some fact to back it up. Religion is a strong elief, and science may elaborate on that belief. In fact, Islam encourages scientific research. Time and time again, it is mentioned in the Quran (holy book) to reflect, not to just blindly believe. A verse in the Quran states, â€Å"And it is He who spread the earth and placed therein firmly set mountains and rivers; and from all of the fruits He made therein two mates; He causes the night to cover the day. Indeed in that are signs for a people who reflect† [13:3] . This verse encourages us to reflect over these â€Å"signs,† to do research and believe with reason. It is only through research that religion is understood and appreciated even more. In Islam, it is believed that the Quran, the holy book was brought down over 1400 years ago, during the 7th century. That was a time when people didn’t know many of the scientific facts we know now. They weren’t advanced enough, and they didn’t have the correct technology. It was a time when people thought that the world was flat. The Quran, however, stated differently, it hinted at the roundness of the Earth. â€Å"He has created the Heavens and the Earth for Truth. He wraps the night up in the day, and wraps the day up in the night† [39:5]. The Arabic word that translates to â€Å"to wrap† in this verse is â€Å"yukawwir,† which comes from the origin â€Å"kurah† meaning sphere. Also, in this verse, wrapping the night up in the day means that the night slowly and gradually turns to day, which could only happen if the Earth was round. Another example is the formation of rain. The three stages of rain formation are the â€Å"raw material† of rain rising up into the air with the wind, clouds forming from the water vapor, and finally raindrops falling. In the Quran, it is stated, â€Å"It is Allah Who sends the winds which stir up clouds which He spreads about the sky however He wills. He forms them into dark clumps and you see the rain come pouring out from the middle of them. When He makes it fall on those of His servants He wills, they rejoice† [30:48]. The stages of rain formation weren’t discovered until after the weather radar was invented, but the same stages are discussed in the Quran. These are just two of many scientific signs in the Quran, but it shows that in Islam, absolute religious text and absolute scientific fact never contradict. Many people believe that religion and science can’t coexist because they cancel each other out. It is either one or the other, but this just simply isn’t true. In Islam, there is no conflict between absolute scientific fact and absolute religious text; everyone would be able to see this if they really looked into both of these factors. Religion actually encourages people to expand their knowledge through scientific research and come to a deeper understanding of their religion.
