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.
Fungi Fungi are skin infections caused by dermatophytes and yeasts, which are groups of fungi that are normally harmless. When these grow excessively, it causes symptoms and usually affects your skin because they live of keratin. Parasite A parasite is a life-form that survives off its host, including worms, bacteria, protozoa and amoeba. Parasites often work by stealth—you probably don’t even notice their presence. In the meantime they rob your system of nutrition, loading you down with their excretions and secretions these include Lice and Ringworm 1.3 Colonisation is when a bacterial strain invades a region of your body and starts to rapidly divide - it sets up a new colony Infection is similar but only usually used for opportunistic pathogenic bacteria - that is it does not usually refer to bacteria that normally inhabit us 1.4 Localised infection is restricted to a ceratin region of your body Systemic infection means that the infection is throughout your body.
1.2 Identify common illnesses and infections caused by bacteria, viruses, fungi and parasites The most common illnesses and infections that occur due to bacteria, viruses, fungi and parasites are Dioreah, Vomiting, Influenza, Nail infections, Tick bites, Colds, Skin Conditions, Digestive Problems ( Parasites - Worms ) and in some cases, Death. 1.3 Describe what is meant by “Infection” and “Colonisation” As defined by : www.freedictionary.com INFECTION Invasion by and multiplication of pathogenic microorganisms in a bodily part or tissue, which may produce subsequent tissue injury and progress to overt disease through a variety of cellular or toxic mechanisms. This means that Infection is the process of infecting or being infected. COLONISATION A mass of microorganisms in a culture that originates from a single cell. This means that when either a Virus, Bacteria, Fungi or parasites in the single form, gather and join to make one mass of either Virus, Bacteria, Fungi or parasites.
It can be caused by raw meat coming in contact with already prepared food or unwashed food, and undercooked food. The main cause of salmonella is coming in contact with feces from a person or animal. As gross as this sounds it does happen due to people not washing their hands, thus causing salmonella to enter the body and go into the intestines and that is where it lives until killed. It is a very small bacteria that cannot be seen by the human eye just by microscope. Salmonella is very serious when it is contacted and can be deadly, so make sure you follow proper hygiene to ensure that you are getting any bacteria off of your food and hands.
They also feed on many Bacteria in decaying matter organisms to survive. Parasites are organisms that attach themselves to a host to infect, reproduce or spread diseases that it would be carrying. (2) Common illnesses and infections caused by Bacteria, Viruses, Fungi and parasites would be as follows. Bacteria which is present in food for example can cause Food Poisoning, Salmonella, Botulism, and other internal infections of the Stomach. Typical Viruses are illnesses like smallpox, measles, mumps and tuberculosis etc which can be contracted by touch or being within an environment that has the virus in the air.
All wounds, even minor cuts and scrapes, should be treated as contaminated and potentially serious and should be carefully cleaned to prevent infection. Some wounds, like in this case a bite, always carry a high risk of infection, especially because the wound contained imbedded foreign material (the tooth of the fish). This wound should have been left open to drain and medical consultation should have followed immediately; these wounds require antibiotic therapy and careful follow-up. Yet, an infection would still occurred, whether the tooth of the fish was in the wound or not, because of the bacteria that gotten into the wound and because the wound was not treated properly.

Some believe that the Asian Carp should be kept alive because of their nutritional value and their recent emergence in restaurants. It has recently been learned that the Asian Carp are rich in nutrients, more specifically the Omega-3. Omega-3s help promote normal body functions, good emotional health, weight loss, and lower chances of developing cardiovascular problems such as heart disease and black arteries. (Horng, 2010) According to a recent article in ABC news the fish have around seventy percent more Omega-3s than catfish and tilapia. (Horng, 2010) Restaurants serving freshwater fish are very intrigued with the idea of adding Asian Carp to the menu.
To be pathogenic, a parasite must invade the host, resist internal defenses long enough to begin growing, then harm the host in some way. Pathogenic prokaryotes cause about half of all human diseases. Opportunistic pathogens
Some of the world’s most serious and deadly diseases are viral. In order to cause disease bacteria must enter the body. Routes for bacteria include; cuts, contact with infected faeces, contaminated food or water, close contact with an infected person, breathing in droplets from an infected persons cough or sneeze or indirectly by touching a contaminated surface. Viruses can be spread from one person to another through coughs and sneezes, vomit, exposure to infected bodily fluids, sexual intercourse and sharing infected needles. Fungi infections, there are several types of fungal infections.
Red is the endangered areas In image 2, the most endangered reefs are in areas that are considered “Third World”, where populations have limited access to education. The people here are concerned mostly with putting food on the table now, later can wait for another day. There is a problem with reef systems today that directly comes from people who probably did not know that they were causing it. Runoff from sewers, especially untreated sewage kills corals by: * Suffocating corals and zooxantheallae by covering them with sludge and cutting off
