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.
Megan Jackson English 201 Bauman September 14, 2015 “Human-Animal Food Web” Sandra Steingraber wrote “Tune of the Tunafish” as to raise awareness about the mercury in seafood. There is an especially heavy concern towards the high levels which are in tuna fish, Steingraber says. High mercury content in fish has been known to have many negative effects on the human body. Some of these negative effects can be very serious and threatening, especially when considering neurological health. As Steingraber stated in her story, “Mercury has been shown to paralyze migrating brain cells and hold back their cell division.
If there are lower levels of potassium, then the resting membrane potential will be higher than normal and an action potential will be more likely with less stimulation. Less voltage will need to be used. 2. Tetrodotoxin, a toxin found in puffer fish, acts by inhibiting voltage-gated sodium channels. Eating improperly prepared puffer fish sushi can be fatal because of interference with action potential generation.
Hooked On a Myth Re “Hooked on a Myth,” Commentary, October 8: Victoria Braithwaite argues that fish have feelings. I agree. Just because fish don’t show any emotion in a way we can see doesn’t mean that they don’t feel pain. People think that because they don’t how emotion we can treat them any way we want Studies show that fish have the same two types of nociceptors that we do, allowing them to detect pain. For example, Braithwaite stimulated the nociceptors by injecting dilute vinegar or bee venom under the skin of the trout.
Fish oil is filled with Omega-3 fatty acids which are considered essential fatty acids, the human body can’t produce them so we have to either eat the foods with them in it or fish oil pills work perfectly too. “Research shows that omega-3 fatty acids reduce inflammation and may help lower risk of chronic diseases such as heart disease, cancer, and arthritis.” (Ehrlich,
Aquatic environments are generally split into three categories; fresh water, marine (salt water) and estuarine (a combination of salt and fresh water). The organisms that live in each of these environments have specific adaptations that allow them to respond to changes in their surrounds. Fish generally prefer either fresh water or salt water and are unable to cope with a change from one to the other. For example the cells in fresh water fish are saltier than the surrounding water, so due to osmosis (the diffusion of water through a semi-permeable membrane) water is constantly flowing into its body. For this reason fresh water fish require very efficient kidneys to remove all of the extra water, and methods of maintaining and collecting the salt lost through urination.
You will want to increase your daily calorie intake by 300 to 500 calories a day. What you eat is more important than how much. Eat plenty of fruits, vegetables, extra protein, whole grains, and dairy, which have lots of vitamins and minerals. Foods that you will want to avoid during pregnancy are uncooked meats and seafood.

Second, bottled water is harmful for human being and the environment according to the Environment Working Group. Bottled water is costly and wasteful, but this does not stop people around the world and especially those living in developed country to be addicted of bottled water. The typical cost for tap water is $0.0015/gallon while a gallon of bottled water at prices ranging from $0.89 to $8.26 per gallon. The big difference in cost does not encourage me to drink bottle water because Water is a gift from our nature I do not think that the bottled water industry has the right to sell water in a such a high price since the only thing that they do on it is to filter it and put it in plastic bottle. According to EWG, people believe that the taste that taps water has meant that tap water is bad that is why the run to bottles water despite his cost.
The items you will need now include a filter, a heater and a light housing. Everything involved in aquariums is crucial, but heaters are especially, because fish are very sensitive to temperature changes. My first tank did not have a heater with a high enough wattage and my fish did not survive the lack of heat. The last thing you need to consider is water and how pure the water in your area is. Fish are very sensitive to chlorine and other impurities in tap water.
For example, tomatoes are injected with fish gene to make a new product with better quality because the components in fish can protect fruit from freezing. Nevertheless, this matter can cause a serious consequence for people who get allergic with fish. Hence, labeling will allow consumers to identify and steer clear of food products that could cause them problems. Last but not least, labeling GM foods
