This is a natural occurring toxin, that is caused by some types of microscopic algae. This toxin affects the nervous system and can even cause damage to the muscle system. In other cases, when the toxin level is high, it can cause a severe illness or death ("Paralytic Shellfish" 1). After eating a contaminated shellfish, symptoms can start within a few hours to a few days. The symptoms can vary from burning of the period area, tingling, and
Salmonella When people eat raw foods, it creates a bacteria that can be harmful to the body called salmonella. This bacteria has wavy hairy, longs whips behind it. It moves in the body, by swimming through the bloodstream. Salmonella is caused by undercooked food. It goes through the mouth down to the esophagus that connects to the stomach, liver and gallbladder that all connects to the intestines, the small and the large.
Abstract Fish malodor syndrome or Fish Odor Syndrome (FOS) is a genetic disorder in which the patient emits a foul odor caused by trimethylamine. People with this syndrome cannot lead a normal social life and some suffer from clinical depression and suicidal thoughts. In this review the clinical biochemical and genetic features of the disorder are described, as well as the psychosocial sequels. The principles of therapy, including dietary, pharmacological and life style changes will also be discussed. Keywords: Fish malodor syndrome, genetic disorder, trimethylamine, therapy Abbreviations: FOS-fish odor syndrome, TMA- Trimethylamine, TMAO - Trimethylamine-oxide, TMAU-trimethylaminuria, FMO3-Flavin monooxygenase 3 Introduction Claire, a young woman, suffered for years of a very unpleasant smell from her breath and body.
The Asian carp should be removed from the Great Lakes as shown in the following paragraphs. The Asian carp are an invasive species because they are killing off many native species by either destroying their habitats or eating a large amount of food. Their population spreads very quickly, which makes it hard to stop or control them. Carp that are filter-feeder often compete with fish such as bigmouth buffalo and paddlefish, by taking away some of their food sources. They can also affect human lives; they have been known to jump up to 10 feet out of the water and even break bones.
This shows that an environmental threat that blue crabs face is pollution because if about 1 million animals are dying each year because of pollution, we have a serious problem. Furthermore, another ecological hazard that this incredible animal faces is fishing and it’s equipment. According to the text, “Modern fishing methods have created some serious problems for the ocean. The populations of almost all fish species that we eat have shrunken,”(Dignan 14). This proves that another environmental threat that blue crabs faces are fishing because they may not be a type of fish, but, like most crabs, they are fished, caught and sold.
Their blobby appearance is due to a lack of bones and muscles. Blob fish are typically shorter than 30 cm. They live at depths between 2,000 and 3,900 ft where the pressure is 60 to 120 times as great as at sea level, which would likely make gas bladders inefficient for maintaining buoyancy. Instead, the flesh of the blob fish is primarily a gelatinous mass with a density slightly less than water; this allows the fish to float above the sea floor
Luther King says in "9 Interesting Facts and Statistics about Littering", 1.9 billion tons of litter end up in the ocean. The ocean is another ecosystem made up of many diverse animals and plants. In “ 5 Ways Pollution Is Killing Animals”, Abigail Geer tells us that there are many things that can pollute the water ranging from noise, chemical and acid runoff, waste water and oils. All of these types of pollutions are affecting the marine life drastically. Abigail tells us that noise pollution is hurting animals that use sonar to get around are becoming closer to extinction.
According to the article, Shark populations healthy but still at risk, study finds, by Timothy Hurley, overfishing is the main cause of the population declining. Numerous sharks have been caught and thrown back after their fins have been cut off, the process is known as finning. For this reason, fins are used for soup, a delicacy known as shark fin soup. The dish supposedly offers various benefits to our bodies. However there is no scientific fact to support it.
Salmonella Typhi Introduction The typhoid bacillus or simply typhoid is caused by salmonella typhi bacteria, it usually and mostly infect only humans. Entric fever and paralyphoid are from other species of salmonella, this infect all domestic animals and also human. The typhoid fever is an acute and a dangerous disease that is caused by bacterium salmonella entrica serovar Typhi. The bacteria enters the body of human trough the ingestion of contaminated substance ( i.e water, food e.t.c) from the mouth which then affect the intestine wall and multiplies in the lymphoid tissue and thereafter infect the blood stream and lead to bacteremia. Typhoid fever or Salmonella typhi major epidemics have been linked to pollution of public water.
In her experiment she founded “ fish found these naturally irritating chemicals unpleasant too. Thier gills beat faster, and they rubbed the affected area on the walls of the tank, lose intrest of food and had problems making decisions.” You can say fishes almost react the same as humans do when in pain or sick. When something irritates me the first thing I always do is rub the area that's bothering me, and when most people are sick or suffering from an illness there are most likely to be distraught. If fishes can feel irritation on there body and rub against the side of the tank then they must be feeling a type of pain or burning sensation that would cause pain. If a fish couldn't feel pain they wouldn't run against the side of the tank neither would their gills would beat faster then normal.
