Weaknesses of Esther and Plath Exposed in Sylvia Plaths The Bell Jar E

Weaknesses of Esther and Plath Exposed in The Bell Jar   Ã‚  Ã‚  Ã‚   The glass of which a bell jar is constructed is thick and suffocating, intending to preserve its ornamental contents but instead traps in it stale air.   The thickness of the bell jar glass prevents the prisoner from clearly seeing through distortion.   Sylvia Plath writes with extreme conviction, as The Bell Jar is essentially her autobiography.   The fitting title symbolizes not only her suffocation and mental illness, but also the internal struggle of Plath's alter ego and novel protagonist Esther Greenwood.   The novel illustrates the theme confinement by highlighting the weaknesses of both Esther and Plath.      Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Esther's first statement, "It was a queer, sultry summer, the summer they electrocuted the Rosenbergs"   (1) sets the tone for the novel and establishes her preoccupation with death.   She alludes to no remorse at the loss of life but rather concentrates on the wonder of execution. This style allows the reader to see the development of confinement; that is, Esther's preoccupation with death entraps her within herself.        Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   It is perhaps her over-analysis of situations that causes the manifestations of her psyche; she consistently volleys between multiple possibilities, searching for the most fruitful option.   The novel's theme is consistently shown as a mental battle of Esther versus herself, a direct result of her mental illness.      It is obvious that Esther is at a crossroads and feels torn by life.   She best describes her feelings with the following passage:   "I saw myself in the crotch of this fig tree, starving to death, just because I couldn't make up my mind which of the figs I would choose.   I wanted each a... ... her a strong person.    Works Cited and Consulted: Brennan, Sheila M.

Comparison and Contrast of The Destructors and The Rocking Horse Winner

Comparison and Contrast of â€Å"The Destructors†, by Graham Greene and â€Å"The Rocking Horse Winner†, by D.H. Lawrence This comparison and contrast of â€Å"The Destructors†, by Graham Greene and â€Å"The Rocking Horse Winner†, by D.H. Lawrence will center on selected parts of stories from the opening through the conclusion. I will seek to compare and contrast both authors’ choices of characters, themes, techniques of suspense, moral statements, and conclusions. â€Å"The Destructors† and â€Å"The Rocking Horse Winner† were both written in the third person by British authors and set in post war Great Britain. â€Å"The Destructors† was written post World War II and â€Å"The Rocking Horse Winner† was written post World War I. Misery caused by poverty is the underlying theme of each story. The significance of the period each story was penned can easily be understood when considering the miserable living conditions of the people of post war Great Britain. The characters in â€Å"The characters in â€Å"The Destructors† are not as fully developed as those in â€Å"The Rocking Horse Winner†. In â€Å"The Destructors† the characters are bound together as a distinct unit or a gang. Their overall interaction is based primarily on the destruction of Old Misery’s house. Dialogue between the gang members is limited to a great extent on the house’s destruction. In contrast, â€Å"The Rocking Horse Winner† characters, Paul, his mother, his uncle, and Bassett, are in constant conflict over poverty and bad luck as opposed to wealth and good luck. â€Å"The Destructors† is a story about the gang-style activities of young boys living in the inner-city poverty of post-war London and their conspiracy toward destroying an old man’s house. The opening of â€Å"The Rocking Horse Winner† sets the tone, moo... ...which in turn led him to seek games of chance. The conclusion of both stories is sad. In â€Å"The Destructors†, not only is Old Misery’s house destroyed, but also during the latter part of the demolition, the gang holds him captive in the out-house. The final humiliation appears when the lorry driver is an unknowing accomplice but still finds humor in Old Misery’s house being razed. In the â€Å"Rocking Horse Winner†, tragically although Paul selects the winning horse of the derby and brings wealth to his family, he dies in the end. Paul’s last words to his mother were â€Å"I’m lucky†. In conclusion, the two short stories as compared and contrasted above, depict the degradation of social norms caused by poverty. The two sets of characters’ reactions to this abasement are different, and both prove ineffective attempts to overcome or cope with the situation.

Photography in Flux Essay -- Digital Photography Pictures Technology E

Photography in Flux It is no secret that digital photography is very rapidly finding a niche in modem society, in both the professional realm as well as in the home. The advent of newer, faster, and more embellished technologies have placed the power of photographic production in the hands of the common person. An art form that formerly was left to the charge of few skilled professionals has been forever changed by these technologies. Certainly, this evolution of sorts has its strengths as well as its drawbacks. What advantages does a photographer have with digital technology that he or she might not have with a traditional camera? What are the disadvantages? And what does this technology mean for the future of the photography trade? First, what exactly is the fundamental technological difference between digital photography and conventional film? In Tom Ang's The Art of Digital Photography, he says that "the key difference is the light-sensitive medium used to capture the image" (10). Okay. Well what does that mean? Images in traditional film are created when "silver salts suspended in the emulsion convert the amount of light falling on them into a latent image" (Ang 10). When film is developed, the chemical processes that occur magnify the changes to produce a viewable image. By contrast, digital cameras have an electronic sensor that converts the light falling on it into an electrical charge, which is then processed by electrical circuitry and turned into a code that can be stored, transported, copied, etc. Advantages Essentially, once an image exists in digital form, it can either be tweaked to adjust even its most indiscernible features or it can be entirely morphed into something altogether different.

One Flew over the Cuckoo’s Nest Essay

The six psychological approaches are biological, learning or behavioral, cognitive, sociocultural, psychodynamic, and humanistic. Each approach is unique in its own way and used by psychiatrists to diagnose the problem. A biological approach is applied when the there is a known medical condition. The medical condition normally connects to mental health, and the solution comes from therapy. This particular approach looks at the whole body. The learning or behavioral approach is all about analyzing the person’s the behavior and modifying their behavior biased on their response to the environment. This approach works from positive and negatives items in their environment, and is sometimes cured by brings these elements in and out of their life to fix the problem. The events in the environment can be rewards or punishments that will influence the patients behavior. The cognitive perspective is about understand a patients thinking and understanding. How we process, store, and retrieve information influences our behavior. It is said that all problems are located in the brain, and using this perspective you can find a medical issue that is affecting how the brain is working. The sociocultural approach is when the mental health has something to do with the environment that deals with growth. The culture in which the patient is a large factor. In a psychodynamic approach an individual’s problem is inside the unconscious mind. This can be from a dramatic event that happened earlier in their life. Sometimes the cure can be from the patient themselves accepting the fact, or acknowledging that they have a problem. The final approach is a humanistic approach. This is about individual or self directed choices that influence behavior. This approach deals with the physical health of a patient to eventually cure their mental health. There is a well known philosophy that a healthy mind equals a healthy body. In this approach, a psychologist will control the patients diet and exercise to regain their mental health. The hospital used many methods on the mentally ill patients. They had group counseling scheduled every day where Mrs. Ratchet interrogated the patients and made them feel uncomfortable. The hospital also had electric shock therapy and lobotomy as other treatment methods. Also, the hospital gave the patients medicine, this is a biological approach, even though it was given to these people unwillingly. Mrs. Ratchet also allowed McMurphy to receive a vote in order to watch the ball game and she bended the rules or was too strict in order to win her position. This is a behavioral approach because McMurphy watched the baseball probably in his normal environment at home. She teased him with the thought of watching the game as a reward, then took it away. McMurphy had behavioral or learning approach. He would congratulate people when they did things he thought were good and he would yell at them when he thought they did something bad. For example, when McMurphy taught Chief how to shoot a basketball, he cheered after every point he made. The other patients looked up to and really admired McMurphy, which put him in a very powerful position. He had a strong effect on the other patients and they really admired him. Chief Bromden’s recovery began when McMurphy came to the hospital and started talking to him and making him do tasks. McMurphy worked on chief to see if he was smart enough to complete simple tasks. The first step was him raising his hands above his head at the basketball court, which was the first movement he had done in his whole time being there. Before chief wouldn’t handle directions from others very well. His next step was raising his hand to vote on watching the baseball game, which McMurphy also encouraged greatly. Later, McMurphy rounded up the patients to play some basketball. McMurphy passed the ball to Chief and he shot it, which was followed by him beginning to follow orders and run up and down the court. The final step was when McMurphy gave him the gum before Electroshock Therapy and the Chief spoke fo r the first time at the clinic. After this, chief revealed his intelligence to McMurphy. Ken Kesey was always very interested, and was very talented with the subject of psychology. In 1959 he volunteer to take part in a study named Project mkultra  , this was a CIA funded project dealing with psychoactive drugs. Some of the drugs included were LSD, psilocybin, mescaline, cocaine, AMT, and DMT. This and his work at the state veterans hospital, which gave him access to LSD, inspired him to write One Flew Over the Cuckoo’s Nest. At the state veterans hospital, Kesey spent a lot of time talking to the patients. sometimes under the influence of the hallucinogenic drugs with which he had volunteered to experiment. Kesey did not believe that these patients were insane. Kesey believed that society had pushed them out because they did not fit in the the culture, and that they just wanted a place to keep all the mentally ill. I think that Kesey was trying to convey to people at mentally ill hospitals were treated in a bad manner. He tried to show people that the mentally ill were probably sheltered away from everybody just because they were different. The hospital portrayed in the film didn’t seem to help the patients out or want them to recover and go home. They seemed to have no rights. These patients adjusted to this lifestyle and didn’t want to leave, that is a problem when the assumed goal was to improve these people’s problems. The rewards from good behavior seemed nonexistent and He also wanted to show how cruel the punishments were in the hospital. â€Å"Psychedelic 60s: Ken Kesey & the Merry Pranksters. † Psychedelic 60s: Ken Kesey & the Merry Pranksters. University of Virginia / Charlottesville, Virginia, 16 Dec. 2009. Web. 19 Sept. 2012. . I really enjoyed One flew over the Cuckoo’s Nest. I thought the movie was genius. There were parts of humor, and it kept you interested and wondering so many things. I enjoyed that there were many main plots and side plots, like the hospital verses the patients, or the patients versus their own recovery. McMurphy was a very mysterious character, because he was crazy, and nobody could figure out if there was anything wrong with him. I though that putting him in that section of the hospital was a mistake, because he is so manipulative and high functioning that he abused all the hospital’s loop-holes. At the same time he was very good for the patients. I also enjoyed the character and all their different problems and personality differences. I enjoyed watching how Billy and the Chief progressed mentally throughout the film. I also love the thought of people breaking structure, and that is what McMurphy definitely succeeded in. This movie very closely related to psychology, because it directly dealt with people who were mentally ill. Also psychology was involved when McMurphy used his genius mind to go against the hospital in various ways. Thinking of these schemes uses a large amount of psychology. Even for the viewers, the movie left you deep in thought, with predicting and questioning what is going to happen next. This movie made you think deeply making this a very psychological movie.

Case Study on Euthanasia: Elderly cancer patient

In most evangelical Christian opinions, in cases where patients are terminally ill, death appears imminent and treatment offers no medical hope for a cure, it could be argued that it is morally appropriate to request the withdrawal of life-support systems, allowing natural death to occur. In such cases, every effort should be made to keep the patient free of pain and suffering, with emotional and spiritual support being provided until the patient dies.But in this case where the cancer patient seems to still have a chance, although quite small, it is critical that we not only understand what is going on in the world around us but that we also understand what the Bible clearly teaches about, life, death, pain, suffering, and the value of each human life. First, the Bible teaches that we are made in the image of God and therefore, every human life is sacred (Genesis 1:26). In Psalm 139:13-16 we learn that each of us is fearfully and wonderfully made. God himself has knit us together in our mother's womb.We must be very important to Him if He has taken such care to bring us into existence. Second, the Bible is very clear that God is sovereign over life, death and judgement. In Deuteronomy 32:39 The Lord says, â€Å"See now that I myself am He! There is no god besides me, I put to death and I bring to life, I have wounded and I will heal, and no one can deliver out of my hand. † Psalm 139:16 says that it is God who has ordained all of our days before there is even one of them. Paul says essentially the same thing in Ephesians 1:11. Third, God's purposes are beyond our understanding.We often appeal to God as to why some tragedy has happened to us or someone we know. Yet listen to Job's reply to the Lord in Job 42:1-3: I know that you can do all things; no plan of yours can be thwarted. [You asked,] ‘Who is this that obscures My counsel without knowledge? ‘ Surely I spoke of things I did not understand,things too wonderful for me to know. We forget that our minds are finite and His is infinite. We cannot always expect to understand all of what God is about. To think that we can step in and declare that someone's life is no longer worth living is simply not our decision to make.Only God knows when it is time. In Isaiah 55:8-9 the Lord declares, â€Å"For my thoughts are not your thoughts, neither are your ways my ways. As the heavens are higher than the earth, so are my ways higher your ways and my thoughts higher than your thoughts. † Fourth, our bodies belong to God anyway. Paul reminds us in 1 Corinthians 6:15,19 that we are members of Christ's body and that we have been bought with a price. Therefore we should glorify God with our bodies. Lastly, suffering draws us closer to God.In light of the euthanasia controversy, listen to Paul's words from 2 Corinthians 1:8 We were under great pressure, far beyond our ability to endure, so that we despaired even of life. Indeed, in our hearts we felt the sentence of death. But this happened that we might not rely on ourselves but on God, who raises the dead. Joni Earickson Tada's book ‘When is it Right to Die? ’ (Zondervan, 1992) shows her testimony and clear thinking is in stark contrast to the conventional wisdom of the world today. Being a Christian and having pro-life sympathies, I believe this Christian daughter should take the same wisdom and proceed with dialysis.

Drama Analysis Essay

In preparing to write my drama-analysis research paper, I encountered a wealth of information regarding my topic: The Pursuit of Happyness, a film which I believe demonstrates a return to â€Å"classic† movie-making and also a return to film as inspiration rather than lamentation. In my essay, I argued that, despite certain flaws and tendencies to revision historical relaity, The Pursuit of Happyness is a great film , and potentially one of the most important American films. Arriving at this conclusion was a long and interesting road, which was partially established by the research and writing of the paper itself. However, I felt determining my opinions and reinforcing them with information from my research materials was much easier than organizing the paper and expressing my opinions in solid, correctly constructed writing. One approach that I thought would be workable, but which proved to be merely frustrating, was to draw primarily from my own experience and opinions about movies. In my original intention for the paper, I had imagined that I would contrast The Pursuit of Happyness with other films I had seen and contrast, also, the way these various movies made me feel and also what I may have thought about their technical aspects. When I tried to use these kinds of comparisons in the actual research paper, I felt like what had been so obvious to me, as a subjective movie viewer, would be very hard for others to identify with, unless I expended a tremendous amount of space and energy to explain my personal tastes and opinions. What seemed to work better than the inclusion of my extended opinions was the citation of otehrs’ opinions. There seemed to be two advantages in citing material which supported my opinions rather than merely offering my opinions themselves. the first advantage was that i found certain writers expressed my thoughts and ideas just as I would have liked to express them myself. However, because the writers of the articles and essays I cited were professionals, their words were much more succinct and precise than some of my own attempts at saying the same thing. The second benefit of using cited materials was that some of the opinions I cited were, in fact, slightly different â€Å"takes† on opinions of mine, and I don’t think i would have necessarily come to understand these slight variations without having done the research. So, rather than merely supporting my opinions, the research materials actually modified my opinions and sometimes reinforced them very nicely. I felt more confident and determined in my own thesis because I knew authoritative writers from The Wall Street Journal and other professional publications supported some of my views. The only real obstacle I faced with research was whittling down the enormous amount of available information. I think the Internet has made it easier to conduct wide-ranging research quickly, but that in itself makes it much more difficult to sift through all of the available information and pinpoint what will be useful in support of the research paper in question and its thesis. Defining my thesis itself was also challenging. The more I thought about stating my argument simply and directly in a single sentence or a couple of sentences, the less the whole idea seemed meaningful at all. I learned as I continued to work at defining my thesis that it is important to get everything set in a single direction. I’m not sure if I was actually successful in presenting a sharp, simple thesis, but I tried very hard, Essentially, I wanted to show that The Pursuit of Happyness is a good film and one which also returns film-making to a role which it has steadily abandoned over the years in America: that of inspiring people. I believed that the thesis statement is true and feel it is true,. but I found that making my points in writing and spelling them out logically, as well as addressing counter-arguments forced me to reconsider my solidly constructed beliefs. Even though my overall opinions did not change very much, my respect for the logical formation of written arguments grew steadily as I worked on my own paper. Just as it is important to think simply in many way to secure a good thesis for a research paper, it seems important tow rite simply, as well. That is, I think it is important to stay on topic and make your argument point by point rather than digressing or getting too far off of track, no matter how tempting it is to launch into extra thoughts and associations. Even paragraph by paragraph, I think, all of the sentences should be necessary and feed into one another. I wasn’t as aware of this fact before spending time on the drama-analysis research paper. In addition to learning valuable steps and techniques for writing and thinking, the process of writing the paper caused me to re-examine the methods or logic by which I arrive at my opinions in the first place. I think that;s the most important thing I leaned in composing my research paper: that the logic and â€Å"formal† thought that goes into writing a good research paper differs widely from the â€Å"looser† thoughts and associations which typically help define at least my own subjective opinions. I’m not sure IO was aware of just how different my â€Å"everyday† thoughts and logic were from those which are necessary to present a clear, convincing argument which is backed up by solid evidence. In the long run, I feel certain that I could now make, as a consequence of my experience in writing the research paper, a much stronger argument on behalf of my original opinions.

Harmful Algal Blooms and Aquaculture

Harmful Algal Blooms and how they are Linked to Aquaculture Abstract Harmful algal blooms cause a wide range of negative effects on aquaculture. These effects are come from the complexity of harmful algal species; the toxins they create and morphology they have adapted. Science still lacks a full understanding of factors that are envolved in blooms formation. Aquaculture and harmful algal blooms are directly related because it is one of many anthropogenic factors that unintentionally produce the conditions that promote harmful algal blooms.The methods of production, feeds used, waste produced can lead to nutrient loading and eutrophic conditions by releasing essential nutrients into water that are necessary for algal growth. Phosphorus and nitrogen compounds are two of the main byproducts or aquaculture that are associated with bloom formation. To minimize the effects of harmful algal blooms on aquaculture you must understand the diversity and complexity of harmful algal blooms and t heir relationship with aquaculture.

Andrew Blajda Introduction Over the last several decades harmful algal blooms events or HABs are believed to be increasing in frequency and geographic range. The reported increase is a major concern because of the wide scale impact they have on he environment and human activities. The effect of HABs on aquaculture can be very damaging with reduced growth, mortalities or accumulation of toxins. If aquaculture operations take place in the open bodies of water they have little or no way of avoiding incoming blooms. Harmful algal bloom events that come in contact with aquaculture operations often have negative effects that can include student growth, weakened immunity, mortalities, and on economic losses.One of the bigger concerns today is the apparent increase in harmful bloom events. Researchers have linked this increase with anthropogenic activities, aquaculture being one of them. Aquaculture operations adds additional nutrients to the system, this lowers nutrients that l imits algal growth. A better understand of the dynamics and characters the form and make up a bloom combined with the a better understanding of nutrient loading of aquaculture could potentially help reduce the negative effects harmful algal blooms have on aquaculture.Single celled microscopic algae like phytoplankton are the most globally abundant species and one of the oceans’ most important resources. These autotrophic primary producers form the bottom of the food pyramid, acting as the primary source of food for larval finfish, crustaceans, filter feeding bivalves, and other species (Hallengraeff, 1995). In normal concentrations, these single celled algae work in balance with the ocean and its inhabitants, filling important roles in chemical and nutrient cycles. They act as primary producers, providing nutrients and food for variety of different species.These simple microscopic species are vitally important to the success of both fisheries and aquaculture, but in some situ ations they can also have detrimental effects on the marine and coastal environment and numerous terrestrial and marine species. A combination of physical, chemical, biological, hydrological, and meteorological events can generate appropriate conditions that allow these simple single celled microalgae can exhibit exponential growth and reproduction. These natural events create the opportunity for algal bloom formation with potential large scale negative effects throughout the area they cover (Graham, 2007).Algal blooms can be very diverse and differ from one another in many ways . How they form, the algal specie of causation, characteristics and dynamics of a blooms, the species they affect, and impacts they cause are some of the complex factors that are found in blooms (Zingone & Enevoldsen, 2000). The specific characteristics used to define a harmful bloom vary by sources. Hans Paerl, among others, defined harmful blooms by using several characteristics. Paerl also defined harmful blooms at their most basic level by classifying them as having nuisance conditions, meaning ecological and/or economic impacts (Paerl, 1988).As harmful algal blooms move across the ocean, the observable effects they cause go beyond the ocean and marine species it covers. These events will also have wide spread negative impacts on costal terrestrial organism and both human health and activities. Algal species produce sevral different toxins that are detrimental effects to human health, causing various illnesses and mortalities. About 10% of foodborne disease in the United States results from algal toxins; worldwide they cause more than 60,000 intoxications a year. Van Dolah, 2000) Economic losses due harmful algal blooms have been estimated in the tens of millions of dollars, from costs of beach clean ups, decreased tourism, and closing or stopping sales of commercial fisheries and aquaculture (Van Dolah et al. , 2001). Over the past several decades there has been an apparent increa se in the frequency and geographic range of harmful algal blooms. This apparent increase has been attributed to both increased observations and focus on harmful algal blooms and increased inputs from anthropogenic sources.Aquaculture is one of many anthropogenic activities that is believed to be hypernutrification and eutrophic conditions in surrounding bodies of water. This paper will attempt to gain a better understanding of diversity of harmful algal blooms and also the effect aquaculture has on the environment in adding in formation of harmful algal blooms. Algal Blooms Historically algal blooms are a naturally occurring phenomenon in earth’s oceans and have been observed throughout recorded history (Hallegraeff, 1993).These events are often beneficial to bivalves by supplying an abundant food supply to these filters feeding that relay on microalgae for their source of nutrients. Algal blooms can quickly turn into detrimental to the environment and its inhabitants are var ious ways (Leverone, 2007). Sources from human history including the bible may contain the first documented cases of algal blooms. In Exodus 7: 20-21 referring to one of the plaques on Egypt â€Å"all the waters that were in the river turned to blood, and the fish that was in the river died†.Some historians and scientist now believe this biblical reference from 1,000BC could be the first written record of an algal bloom. (Hallegraeff, 1993) Other historical sources may have unknowing recorded written evidence on algal blooms, in China around 200AD general Zhu Ge-Ling documented sicknesses and losses of military personnel after drinking from a river that was stained green. (Chorus & Bartram, 1999) Examination of fossil algal specimens and historical reference compounding evidence that these event are not a new phenomenon and have been occurring in earth’s oceans for thousands if not millions of years.Recent finding from numerous long term studies conducted around the wo rld has brought a strong belief in the scientific community that algal blooms have been increasing in their frequency and geographic distribution. Even though most scientiest support the idea of a global increase of blooms and twith strong evidence supporting this theroy there is still a major dissagreement about what is causing the increase (Pelley, 1998). The apparent increase of algal blooms, along with the global impacts on aquatic organisms, the environment, human health, and activities has increased interest and research being done on these events (Li et al. 2002; Van Dolah et al. , 2001). The exact characteristics and descriptions that define an algal bloom are fairly broad and very from source to source. I was unable to find a universal definition of algal blooms. The description and definition I came across were similar but differed in many aspects; this included sizes, formation factors, impacts, and algal species. Overall algal blooms are generally defined significant inc rease in biomass due to a rapid reproduction of a single microalgal species.The problem with this source is there can also be macroalgal blooms. Others described them as forming high density populations, with some species creating visible discoloration of the water. (Carstensen, Henriksen, & Heiskanen, 2007; Diersing, 2009) Others define blooms by impacts they cause; displacing indigenes species, destroy habitat, oxygen depletion, and alter biochemical cycles. (Hoagland et al. , 2002) A more generalized definition was given by Hallegraeff, adding that a bloom must have at least million cells per liter (Hallegraeff, 1993).The defining characteristic that differentiates a bloom from a harmful algal bloom is when they takes on a destructive roll and causes environment impacts. The term harmful is defined more specifically as causing negative impacts on the environment and adverse effects on both aquatic and terrestrial organisms. This is due to factors such as toxins they produce, spec ie specific cell physical structure causing damage to aquatic organisms or by accumulation of biomass affect naturally occurring organisms causing alterations food web dynamics and biochemical cycles (Anderson et al. 2002). Depending on the species, some algae produce toxins that can affect crustaceans, fish, shellfish, birds and mammals including humans; nontoxic species can still causes damage by blocking light from penetrating the water column, clogging or damaging gills, and creating anoxic conditions from accelerated decomposition as they die off (Silver et al. , 2006; Sellner et al. , 2003) Harmful alga can also have impacts on shoreline coastal habitats, toxins can be transported onto the shore by sea spray (Hoagland et al. , 2002).There are over 5,000 know photoplanktonic algal species that inhabit the marine waters only a small portion, about 300 species are known to have blooming capabilities and even fewer, about 40-80 species or 2-3% of all photoplantonic algal species a re known to have toxic chemicals producing capabilities; this includes members that form red tides (Hallegraeff, 1993; Smayda, 1997). Nontoxic red tides are not uncommon, today people often incorrectly or mistakenly refer to toxic algal blooms as red tides even when brown, green or colorless (Anderson, 1994).Toxic and other harmful algal species are ubiquitous throughout the marine and freshwater environment; the majority of the time they present at low population densities that cause few, if any and only minor impacts on the environment and its local inhabitants (Van Dolah, 2000). There are a variety of different phycotoxins algal species are able to synthesize; individual species will only produce one type of toxin. The evolutionary advantages of these toxins are not fully understood; they are believed to play a role in bloom formation and predator protecting (Nehring, 1993).The different phycotoxins vary from one another in terms of the impacts and degree of damage they have on m arine and terrestrial organisms, depending on the toxicity, the concentration, and the organisms. Toxicity vary among algal species Dinophysis is one example, they have the ability to produce toxins that have negative effects at densities as low as 100 cells per L-1 (Sellner et al. , 2003). The most toxic algal species are mainly found in dinoflagellets (Table 1) with some having toxicity greater than venomous snakes. Table 1.Toxicity of several phycotoxins created different organisms including algae. (Van Dolah, 2000) The taxonomic algal groups’ dinoflagellets, raphidophyetes, cynobactria, and some diatoms are known to have the capabilities of phycotoxins production; these species are often the culprit behind harmful algal blooms. Phycotoxins are toxic chemicals created biologically by photosynthetic organisms. Dinoflagellets are one of the predominate species that forms red tides; members of this group also produce toxin that lead to foodborne illness and human mortalities (Li et al. , 2002; Hallegraeff et al. 1995). Human induced illnesses are not an uncommon result from consumption of seafood. Many algal toxins are potentially dangerous and even deadly to humans. Toxins accumulate in tissues of organisms like shellfish, finfish, and crustaceans that come in contact with a toxic bloom. These species are usually far less affected by algal toxins having adaptive mechanisms that lower the effects on the organisms associated with toxic blooms. However toxins still accumulate within the tissues and detoxification can take weeks before they reach levels safe for human consumption.Algal toxins cause for concerns for humans not only because they maintain their toxicity long after the bloom but more importantly because they can withstanding heat from cooking. Algal toxin foodborne diseases are caused by various species or toxins and come from different vectors. Bivalve vectors can induce human illness that include (Table 2) paralytic shellfish poisoning (PSP) , neurotoxic shellfish poisoning (NSP), amnesic shellfish poisoning (ASP), diarrhetic shellfish poisoning (DSP); other vectors can lead to various other diseases as well (Van Dolah, 2000).The popular term of red tide given to harmful algal bloom comes from compact, high densities of algal cells that containing red photosynthetic pigments, causing the water to appear red (Carstensen et al. , 2007). These toxic species can normally be found in low concentrations have no impacts on organisms and environment. The adverse effects on organism often deepened on cell concentration; in blooms toxic algae aggregate and are more dangerous (Van Dolah, 2000).Some toxic algal species have developed unique life cycles and morphological characteristics that allow them to occupy a specific niche that will be further examined. Table 2. Foodborne and environmental disease caused by harmful algal species, the toxin produced and the primary vector they inhabit. (Van Dolah, 2000) Harmful algal species ha ve many adverse impacts on bivalves’ this includes a wide range of sub-lethal and lethal effects; some algal species are more detrimental than others (Leverone, 2007). It is believed that increase frequency of blooms is partially due to the introduction of non-indigenous algal species.Non-indigenous species potentially will create a specific niche, and/or out compete native species. Indigenous naturally occurring harmful algal species are far less direct effects on bivalves; this is because they have been able to naturally adapt to their presence over time. Native algal species in most case do not have as bad direct, detrimental impacts on shellfish and are usually not associated with large scale bivalve die off. The exception to this is in cases of intense blooms (Matsuyama & Shumway, 2009; Nehring, 1993; Zingone & Enevoldsen, 2000).It’s still hard to truly say many large scale die-offs and increase sub-lethal impacts are directly due to non-indigenous algal species b ecause identification is sometimes difficult, longer term data individual algal species geographic ranges are limited combined, and the theory anthropogenic factors are causing an overall increase in blooms. In many circumstance of HAB mortalities it’s difficult to differentiate whether they resulted from the algal specie or unfavorable water quality that coincide with blooms (Anderson et al. , 2002; Leverone, 2007).Complex morphology are found in many harmful algal species that helps protect them from predation and the environment and help obtain nutrients. Diatom algae are members of the Bacillariophyceae class; they have been around for over 180 million years helping to create earth’s atmosphere and also play a major role in nutrient and chemical cycles. Over their evolutionary history diatoms have developed a variety of different exterior cellular morphology for protection from the environment and predation. They have a range of cell shapes and sizes and also form unique frustule cell walls made from silica.The frustule cell wall is made up of two over lapping overlapping silica bands forming a protective shell. The 100,000 diatom species have developed â€Å"seeming infinite variations† of cell wall micropatterns and structures; including ridges, spines and plates (Kroger & Poulsen, 2008) These cellular morphological characteristics help protect them under adverse environmental conditions and restrict or prevent predation. Some species of diatoms have developed such strong cell walls with structural properties that enable them to survive ingestion and escape after passing through the digestive system. (Merkel, et al. 2003) The benefits of these structures do have negative effects and come at the expense of motile abilities, limits growth, and makes the cell very dense; motile restorations and high cell densities make diatoms much more likely to sink out of the high nutrient water column. Bloom Formation The intricacy of bloom formatio n is due to both the abiotic(environmental and anthropogenic factors) and biotic factors; these being the algae themselves. Adaptations of life cycle, morphology, and environmental conditions enable rapid reproduction of certain algal species that have developed specific niches (Sellner et al. 2003; Zingone & Enevoldsen, 2000). Algal blooms formation driven by the complex relation between the environmental factors and algal species; although we understand the basics of formation there are still many unknowns. There are seemingly endless amounts of variables and factors that play a role in creating of a bloom. The main driving factors of when and where a bloom forms are a combination of environmental/anthropogenic factors (nutrient cycles and inputs) and algal morphology (Pinckney et al. , 1997; Sellner et al. ,2003).As simple as it sounds, there are countless variables including natural condition, anthropogenic effects, algal physiological and morphological characteristics that lead to the unpredictability and overall misunderstanding we still have on blooms. (Sellner et al. , 2003; Anderson, 1994) The belief that algal blooms are increasing in frequency and geographic range is a popular belief that is backed by numerous studies. The cause of this apparent increase has been attributed to the expanding human population (anthropogenic effects).Some still argue that the increase in blooms is due to the increase in observations from studies worldwide, a better understanding of blooms and better record keeping; but with overwhelming evidence supporting the lateral it’s hard to believe the human race is not playing a major roll. (Sellner et al. , 2003) Looking at the numer of literary reference to harmful algal bloom over 70 years(figure 1) shows a dramitic increase algal blooms from the 1920’s through late 1990’s (Hallegraeff, 1993). This also give arguments that increase research and technology contriubute to the increase ovserevd.Figure 1. Li terary references of harmful algal blooms from Aquatic Sciences and Fisheries Abstract (AFSA) publications over about 70 years. The increase can be attributed to a combination of anthropogenic factors or increased observations and present arguments for both sides. (Hallegraeff, 1993) Today we have an understanding of the natural environmental processes and factors that lead to bloom formation; but the effects humans apply to the environment alter the natural cycles making it more difficult to predict blooms (Paerl, 1988).Blooms occur under irregular conditions that promote growth and reproduction allowing some species to flourish. The conditions found in blooms broad and often species’ specific adding to the complexity and unpredictability of blooms. In general the conditions associated with blooms are abundance (eutrophic), or an imbalance of nutrients, along with favorable water conditions (temperature, DO, salinity, etc. ). Natural processes like atmospheric deposition, wa ter column turnover, upwelling, oceanic currents, storms, and anomalous weather events (El Nino) work together and fluctuate over time effecting mixing rates, water quality.Nutrients pools build up over time from organic decomposition in benthic sediment. Mixing of the sediment perelapses the nutrient pools and bring about eutrophic conditions or alter the water chemistry that enable specific species of algae to flourish (Sellner et al. , 2003; Van Dolah, 2000; Paerl, 1988). Natural mixing rates occur during regularly during temporal or seasonal with environmental fluxes or randomly from disturbances (natural anthropogenic). Sediment mixing are very important environment processes, releasing nutrients back into the water column allowing for increased primary producer growth.Seasonal and temporal sediment mixing produce lead to the specific conditions that form blooms. Eutrophication has been defined as â€Å"an increase in supply of organic matter to the ecosystem; in terms of alga l bloom this refers to an increase in nutrients that allows an increase of primary production† (Bonsdorff et al. , 1997). Three key nutrients, nitrates ammonia and phosphates are associated with eutrophication and considered the driving forces behind bloom (Sheng, Jinghong, Shiqiang, Jixi, Dingyong, & Ke, 2006). The levels found in marine waters are driven naturally based on natural events discussed above.Studies have found a correlation between anthropogenic actives leading to nitrogen and phosphorus nutrient loading and the apparent increase in frequency of algal blooms along with alteration of natural nitrogen/phosphorus ratio (Bonsdorff et al. , 1997; Paerl, 2009). There are various anthropogenic activities that have led to the both local and global increase of nutrients in fresh and marine waters. Aquaculture is just one of many of these activities. Many studies have shown that aquaculture operations have byproducts that can cause eutrophic conditions.Nutrient loading fro m aquaculture only has local effects and the amount of effects it causes is size dependent (Anderson et al. , 2002). Aquaculture and Nutrient Loading It is important to understand the relationship between aquaculture and harmful algal blooms. Additional nutrients from the feed used, effluent discharge, and waste products are some of the source that lead to nutrient loading (Tacon & Forster, 2003). The amount of additional nutrients added to a system increases based on how intensive the operation is.HABs have wide spread negative impacts on aquaculture, the hope of significantly minimizing these impacts are still years away. To minimize the effects on aquaculture you must understand characteristics and dynamics of blooms, this includes the diversity of species involved and the factors associated with bloom formation. The apparent increase frequency and geographic range of harmful algal blooms is very important to aquaculture because aquaculture plays a role in helping create the cond itions necessary for bloom formation.Aquaculture operations provided year round nutrient inputs in a local aspect, this eliminates nutrient limitations in those areas (Bonsdorff et al. , 1997). This section will discuss and review the relationship aquaculture has with nutrient loading and eutrophication of the surrounding water. Nitrogen and phosphors are to key elements that take on various forms necessary for bloom formation. Both nitrogen and phosphors in the forms of nitrates, ammonia, phosphates and other compounds are byproducts of aquaculture.Algal growth is limited by nutrient availability, mainly based on availability of nitrogen and phosphors in the environment. Nitrogen in the forms of nitrates and ammonia are water soluble and enter the system from either dissolved feeds, effluent discharge, or from waste produced by fish. Phosphates often accumulate mainly in the sediment and during mixing events are released into the water in high quantities (Karakassis, Pitta, & Krom, 2005). Nutrient loading from aquaculture that leads to eutrophic conditions come from several sources. The amount and source of the nutrients depends on the operation.Location of farm (open ocean, ponds, raceways etc. ), what is being cultured (shrimp, finfish, bivalves), what are the inputs (feeds, fertilizer, etc. ) and how intensive the operation is. The source of local nutrient loading from aquaculture can be traced back to where the operation is taking place. Open ocean farming of finfish for instance causes eutrophic conditions right around the cages. On the other hand inland facilities such as pond systems and other flow through systems release effluent discharge causing nutrient in the and around the bodies of water they run into.The species being cultured also plays a major role. Bivalves for instance play a role in limiting algal growth by filter feeding, while finfish inputs and excreting essential nutrients in their waste is a major source of nutrients (Soto & Mena, 199 1). How intensive an operation is and the actual inputs into the system are directly related. The more intensive an operation the more inputs and the more inputs the greater chance of hypernutrification and eutrophic conditions. Different operations require different inputs and these inputs have different nutrient atios. Culture of some juvenile finfish require fertilization to promote phytoplankton growth for feed this puts the essential nutrients for algal growth directly into the system. The feeds used in aquaculture vary on the nutrients they are made up of, how stable they are and whether they float or sink. These factors are all in play in nutrient loading that come directly from aquaculture (Islam, 2005). The effects of aquaculture feeds on nutrient loading depend on several factors. There are three main factors these include; 1) the amount of wasted feed.This is due to poor farming and management practice and floating Vs. sinking feeds. Poor management practices means over o r an improper feeding technique that puts more feed in the water. Floating and sinking feed choices is also important. Sinking feeds may not be eaten by finfish if they go through the bottom of a net or cage, or if they sit on the bottom. On the other hand floating feeds may be less stable or uneaten if they are transported out of a system or to a place where they are unable to be eaten. 2) The actual quality of the feed.This poor stability and high solubility of feed pellets in water mean that once they are in the water they will be broken down and release more and nutrients and in less time. The final factor is deals is loosely related to the previous two. 3) Once the feed is ingested factors such as limitations of absorption and retention of the nutrients from the feed. This factor deals mainly with poor digestibility or metabolism of the species being culture to the feed they are given. The nutrients in the feeds many not be utilized to their full potential once ingested fish wi ll excrete the excess nutrients (Soto & Mena, 1991).Feed and nutrient inputs play a major role in nutrient loading and creating the conditions that promote algal growth either directly in the form of uneaten feeds or nutrients leaching or dissolving from the feeds, or indirectly from the digestion, metabolism and waste products from the species being cultured (Tacon & Forster, 2003). The important of feeds in nutrient loading must not be overlooked one study estimated that 70% of phosphorus and 30-50% of nitrogen in feeds is not utilized by fish and is released into the environment (Soto & Mena, 1991).This only shows two of the most essential nutrients associated with bloom formation and not the various other nutrients that are also released and are important for algal growth. This also shows the significance of feeds based on the large amount of nutrients that are not utilized and instead entering the environment, promoting algal growth. Over all aquaculture farm operations lead to excessive amounts of inorganic and organic fertilizer, feeds, and wastes that are put into local water bodies with high concentrations nutrient, that lead to nutrient loading and eutrophic conditions.Discussion and Conclusions Aquaculture over the last several decades has grown globally in both its production and popularity. In the future aquaculture will continue to grow in its importance to the human population as alternative food source to agriculture and wild fisheries, as well as helping with the depleted ocean stocks. As of now it appear that we will be seeing an increase in aquaculture around the world in the years to come. Although there are many benefits to aquaculture and the potential of increased production may have we must measure the benefits against the environment impacts they cause.Nutrient loading is just one of the environmental impacts associated with aquaculture and the effects of nutrient loading go beyond promotion of algal blooms. The global increase in aqua culture coincides with the apparent increase in harmful algal. Although there are many other anthropogenic factors that are at play in global nutrient loading aquaculture is a major local point-source form. We must understand the specific conditions that are associated blooms and the role aquaculture plays along with how complex and diverse blooms can if we hope to develop mechanisms that can significantly reduce the impacts on aquaculture.I choose the topic of harmful algal blooms and aquaculture effects of nutrient loading because it fits in perfect with our class: aquaculture and the environment. The purpose of this paper was to gain a general understanding of harmful algal blooms, and also to review the factors of aquaculture that lead to nutrient loading, eutrophic conditions, and the aid in bloom formation. This topic caught my attention because of similar topics I’ve cover and work I’ve done this semester in this class and others classes.Harmful algal blooms in general are very interesting because of the diversity of blooms, the range of effects they have, how unique the species involved are, and because of the complexity and over all lack of understanding have in factors of bloom formation. The purpose of this class included reviewing the impact of aquaculture on the environment and methods of reducing or eliminating those impacts. This paper focuses on harmful algal blooms and how aquaculture creates conditions that promoted bloom formation.I focused a great deal of this paper on harmful algal blooms because if you hope to minimize the impacts they cause you must appreciate and understand their complexity and also understand the relation they have with aquaculture. The purpose of this paper was not to examine direct ways in which to minimize nutrient inputs of harmful algal blooms but the information given on harmful algal blooms and the role aquaculture plays in promoting bloom formation is useful to future studies and reviews focusing on ways to minimize the impacts of HABs on aquaculture and help reduce the factors of aquaculture that promote harmful bloom formation.Bibliography Anderson, D.
