Farm raised fish versus wild caught Cul 110 exam #3 Alexis Halstead There have been many different long standing arguments about the differences between farms raised fish and wild caught fish. There are good arguments against which is better than the other. Although these farming practices have their difference, eating fish has great health benefits and that should also be taken into consideration when deciding which product you will be purchasing. Fish are widely advertised for there health benefits, but there are many different controversies surrounding how they caught and able to be produced in mass quantities. Eating about two servings of fish per week provides healthy amounts omega-3 fatty acids that can help to lower cardiovascular disease.
This graph shows the carbon dioxide concentration in the atmosphere above Hawaii from 1958 to 2002. 1. Based on the trend depicted in the graph, explain what you think the relationship might be between organisms performing respiration and the organisms performing photosynthesis in this area of the world. -For the organisms that perform respiration, breathing will be more difficult every year until the amount of carbon dioxide is fatal. As for organisms performing photosynthesis, it would not be much of a problem, considering they take in carbon dioxide.
Phytoplankton populations have also been affected by the warming temperatures in the ocean. Phytoplankton play a role in the conversion of carbon dioxide into organic carbon, and since the rising temperature of the ocean has caused a decrease in the phytoplankton population, higher carbon dioxide levels endanger other marine life, like the coral reefs mentioned earlier. Callum Roberts, a professor at the University of York, explains the importance of marine life by stating that, “They are essential to the health of the oceans and the well-being of
If it came down to people getting really deep into what they are eating and what it’s doing to their body they would be eating hardly anything. In conclusion, tuna consumption does have potential health consequences. However, people should take into consideration that those possible effects, such as the problems the author’s daughter encountered, are very rare. If consumers stopped buying and eating everything that was affiliated with a bad personal experience of someone somewhere in the world, then they would have nothing to consume. Entire parts of the economy would not exist and there would be much bigger problems than just some mercury hurting a very small portion of the population.
2. Do background research – Utilizing at least one scholarly source, describe how variations in dissolved oxygen content in a body of water can affect fish populations. Answer = “Oxygen depletions are the most common cause of fish kills in ponds. (Aquaplant, 2014).” Based on my observation of the chart and what I read, the higher the dissolved oxygen levels the number of fish drops. Dissolved oxygen levels can also cause fish to suffocate and be more susceptible to diseases.
However, they are much less abundant than they were a few decades ago. (Eoearth, 2008). This depletion is as a result of Coral reefs’ sensitivity to thermal stress as their ability to adapt is low (Bernstein et al. 2007). Therefore climate change and high carbon emissions have negatively affected
2. According to Sciencedaily.com 2010 water pollution may also be affecting male fertility rates due to the estrogen in birth control contraceptives B. Because of the potential negative impact on the medical industry, pharmaceutical companies do not want this information to be widely known by the public Transition: Now that you know how it is affecting you this is how it is affecting our wild life. III. Pharmaceutical pollution may be affecting fish by changing their aquatic life cycle.
Scientific Name: Pomatomus saltatrix Common Name: Blue Fish Culture method: Hook and line, pound nets, seines, and trawls. Where/How harvested: The majority of bluefish are caught by recreational fishermen. Most commercial fisheries for bluefish use gillnet, but other types of nets are used to a lesser degree (generally small mesh nets). Sustainability: “Sustainability is about balancing the economic and nutritional needs of today with preservation of ocean resources for tomorrow.” Sustainability has emerged as a result of significant concerns about the unintended social, environmental, and economic consequences of rapid population growth, economic growth and consumption of our natural resources. Is your product sustainable?
Over fishing occurs when there are more fish caught than fish in the ocean to sustain fish stock. Global warming is another big harm to the ocean. Global warming affects all of the earth. Animals are having a hard time surviving because sea levels are rising and ocean temperatures are changing. The sea animal cannot adjust to these changes in the ocean due to global warming.
Many don’t realize that they provide humans with a source of income and more importantly, life for a wide diversity of marine animals. By 2050, there is a possibility that the coral reefs might die out if their habitats continue to worsen (Trinh, 2012). This paper reviews information on what coral reefs are, the importance of coral reefs, information on the Florida Keys and Caribbean, explains the problems they face, and how coral reefs can be helped. INTRODUCTION Coral reefs, one of the most diverse ecosystems, provide life to a variety of marine animals (Coral Reef Protection, 2012). Reefs have been called the “rainforests of the sea,” because they provide homes to numerous marine animals (Trinh, 2012).
