Many consumers today are confused about the controversy about fish and its health effects. Researchers have discovered that fish contains methyl mercury, polychlorinated biphenyls (PCB), and dioxins that may put one’s health at risk (“Harvard College”). The industrial processes cause mercury to be released into the air, then the chemical ends up in the lakes. Therefore, the contaminants come from bacteria that live in lakes that are then absorbed in species. When people consume fish, they are also taking in bacteria that came from unspecialized lakes indirectly through fish consumption. Although people could be harmed by eating contaminated fish, a diet that includes fish can also benefit the body. Fish has become especially popular because the omega-3 fatty acids it contains support cardiovascular health. Omega-3 is essential to the development of brain functions and normal growth. The intake of safe amounts of fish can decrease the chances of stroke, arthritis, and chronic diseases. Although fish contains mercury and dioxins that can damage nerves in humans, the trade-off benefit of the intake of omega-3 from fish can outweigh the risks. Concerns about contamination found in fish can pose a threat to its consumers and put their outcomes at risk. Fish are known to contain the chemicals mercury, dioxins, and PCBS that can be harmful to individuals. These chemicals may build up in a person’s body after years of eating highly contaminated fish that can result to one’s health concern. “In America one-in-six children born every year have been exposed to mercury levels so high that they are potentially at risk for learning disabilities and motor skill impairment and short-term memory loss” (“Mercury in”).

The purpose of this report is to explore the controversial dispute between the quality of two different forms of fish oil supplementation; Triglyceride (TG) and Ethyl Ester (EE). Fish oil can be implemented into a diet by eating either fish or taking supplements. Fish oil is extracted from selected fish that contain highly beneficial healthy oils known as omega-3 fatty acids, two of the most important omega-3 fatty acids that are found in fish oil are Docosahexaenoic Acid (DHA) and Eicosapentaenoic Acid (EPA). Some of these fish that contain healthy omega-3 fatty acids include Tuna, Salmon, Mackerel, Herring, Anchovy’s etc. Fish oil supplementation also often contains small amounts of vitamin E to prevent spoilage and is can be combined with various other minerals and vitamins. There is an array of benefits that are involved when implementing fish oil into a diet; although it’s most common association is that it has been linked to slightly lowering blood pressure or triglyceride levels (fats linked to cholesterol). Although fish oil is recommended for persons with high blood pressure, it’s extremely important to remember that it is only to be taken at recommended dosages as it can ironically increase the chances of stroke when overdosing on the supplement. The scope of this report includes a general comparison between TG and EE fish oil supplements and how they are chemically differentiated, with a focus on how the quality of the two forms of supplement are processed. This report will not focus on other forms of fish oil sources and the impact it might have on irreversible factors such as age, gender, genetics, race/culture or environmental conditions.

Atlantic salmon have become the species of choice to raise on farms because they are more adaptable to the farming techniques and make better use of feed so they produce more salmon with less feed. Not everybody agrees however, that farmed salmon raised in net pens are healthy for the environment or for you to eat. Over the years, there have been numerous stories in the media that have pointed out the negatives of farm raised salmon. These arguments have ranged from wastes from salmon farms, the spreading of disease from farmed to wild fish, the negative impacts of farm raised fish escapes and interacting with native fish, and recently, the effects of farmed salmon consumption on human health. The latest issue that the media got there hands on and consequently got the public concerned, was a report that polychlorinated... ...
More and more research studies are finding that getting enough Omega-3 fatty acids is critical to our health in many ways. Omega-3 fats are essential for the survival of the human body, but our bodies can't manufacture them on their own, so we need to get them from the foods we eat. Good dietary sources of Omega-3 fatty acids are fish and seafood, like salmon, tuna, sardines, halibut, herring, algae and krill, plus some plants and nut oils such as flaxseeds and flaxseed oil, canola oil, soybeans and soybean oil, pumpkin seeds and pumpkin seed oil, purslane, perilla seed oil, and walnuts and walnut oil.
As mentioned before, brevetoxins can cause human respiratory and digestive illness, and consumption of brevetoxin-contaminated fish and mollusks is associated with neurotoxic shellfish poisoning (NSP). According to the data, people in Sarasota, Florida visited the hospital emergency department for digestive illnesses during red tide outbreaks increased by 40% in 2001 relative to in 2002 when there was no red tide bloom (Hoagland, et al., 2014). In addition, multiple substantial effects of brevetoxin immunotonicity are postulated by scientists, such as the inhibition of cathepsin active sites, apoptosis, the release of inflammatory mediators, cell cycle, and oxidative stress. Several effects listed before can have profound problems on human health such as apoptosis, cell cycle and oxidative stress can lead to cancer. The experimental results suggest that the apoptosis postulation is based on the in vitro assay that DNA damage was observed in human lymphocytes treated with brevetoxins and several apoptotic gene expressions were altered in brevetoxin exposed Jurkat cells. The oxidative stress will result in the depletion of glutathione in U-937 human monocyte cell line treated with PbTx-2. Also, DNA strands breakage and chromosome aberrations were observed under oxidative stress (Fleming et al.,
Evidence provided to support these claims of human and wildlife harm is largely from laboratory studies in which large doses are fed to test animals, usually rats or mice, and field studies of wildlife species that have been exposed to the chemicals mentioned above. In laboratory studies, high doses are required to give weak hormone activity. These doses are not likely to be encountered in the environment. However the process of bioaccumulation can result in top-level predators such as humans to have contaminants at levels many million times greater than the environmental background levels (Guilette 1994). In field studies, toxicity caused by endocrine disruption has been associated with the presence of certain pollutants. Findings from such studies include: reproductive disruption in starfish due to PCBs, bird eggshell thinning due to DDT, reproductive failure in mink, small penises in alligators due to DDT and dicofol (Guillette 1994, Colburn et al 1996). In addition, a variety of reproductive problems in many other species are claimed to be associated with environmental contamination although the specific causative agents have not been determined. One recent discovery that complicates the situation is that there are many naturally occurring "phytoestrogens", or chemicals of plant origin that exhibit weak estrogenic properties.

Overfishing is a harmful practice, that will eventually lead to the collapse of aquatic ecosystems, if it’s not dealt with promptly. Overfishing emerges from the combination of our over consumptive society mixed with the great profits that come from hauling in a good catch. The consumers demand for fish in Japan seems to be at an increasingly high rate due to the enjoyment and cultural values that arise from sushi and other traditional dishes involving seafood. Approximately 23 percent of Japan’s protein intake comes from the ocean, and as a nation consumes 7.5 million tonnes of seafood annually. CITATION

The Omega-3's are widely recognized for their role in heart health. Not only do these fatty acids help healthy hearts, they also benefit those with cardiovascular disease. Research has proved atherosclerotic plaque reduces with consistent consumption of omega-3's. Further, incidences of irregular heartbeats decline with these fatty acids; high blood pressure has been known to slightly drops as well.
Together the causes of mercury, and the effects mercury has on the human body prove that mercury is a dangerous metal. The actually effects of mercury and how they get into the human body still overshadow the actions taken to avoid mercury and its effects. The above paragraphs show good reason why the numbers of products in the household containing mercury are decreasing as the years go by. They also provide reasonable doubt as to why such a potentially dangerous metal was ever used in common household products. Such a question may never be answered, however many people may sleep better at night knowing that the question will never have to be answered, sleeping in a mercury free home.
Fish are highly efficient converters of feed into body mass; mostly nutritious protein. Fish also provide many vitamins and minerals in easily assimilated forms. Oily fish such as Atlantic salmon additionally are rich in the polyunsaturated omega-3 fatty acids EPA and DHA known to be beneficial for health. These come from marine raw materials, fishmeal and fish oil, in the diet of many aquaculture species. Therefore aquaculture can be farmed easily while providing great nutrition for the growing
Mercury continues to contaminate the entire marine ecosystem and the food chain until today; mercury enters the ocean mainly from gold mining and other industrial activities, and its impact affected the entire food chain. “In human history, we have learned (I hope) that the conqueror role is eventually self-defeating” (Leopold 279). Humans’ health is threatened by the contaminated fish in the ocean, and if humans do not stop or realize the consequences of carelessly polluting the environment, then we would eventually lead ourselves to extinction.

Omega-3 fatty acids are polyunsaturated fats that in particular have been associated with a decreased risk of developing coronary heart disease and hypertension. Plant sources of omega-3 include soybean oil, canola oil, walnuts, and flaxseed. Eicosapentaenoic acid (EPA) and docosahexaenoic acid are long-chain omega-3 fatty acids found in fish and may be particularly beneficial. The body can make the hormone-like compound prostaglandin from EPA. This particular prostaglandin reduces the blood-clotting rate and thus the likelihood of a clot blocking the coronary arteries (Santrock,
