1.1. Fish food
Like humans do, fish also need proteins, lipids, carbohydrates, vitamins and minerals unfortunately there are not many food which contain all the necessities2. This is tackled by feeding fish a combination of flake, frozen and fresh food. Frozen food can cause problems for fish if the food is not defrosted thoroughly as their intestinal lining is very sensitive and does not tolerate cold food very well. Once the food is thawed properly it can be kept for two days refrigerated but then must throw away. Fresh food which is given to fish consist of plants, animals, microorganisms, meats and vegetables with minimal processing3. There are different types of canned processed fish food for example there are flakes pellets, sticks, tablets, granules, and wafers. Flake food is baked to remove moisture and create the flaking, therefore allowing for a longer shelf life.
There are ten main proteins that are needed to make fish food according to Juli-Anne B. Royes and Frank Chapman1, these are lysine, phenylalanine, arginine, valine, leucine, isoleucine, methionine, threonine, tryptophan and histidine, and these proteins can make up 32% - 45% of the food.
1.2. Degradation of Food
. Most foods have a suitable storage system, some have to be frozen others have to be placed in a cool dry area, but when they are not put in their ‘typical’ storage areas this can cause the nutrients with the food to start breaking down, therefore not supplying the consumer with what they need when it is eaten. If the Food is stored in too high of a temperature it could start to denature the enzymes within the food, or if ...

The aim was to see how the different temperatures affect the protein levels within fish food.
The conclusion is that the results are no reliable enough due to there not being enough of supporting data.

- ... Another difference between the two isoforms lies in the lack of Threonine residues found in the skin AFPs relative to the serum AFPs – Threonine residues in AFPs and AFGPs are characteristic ice binding residues. A lower amount of Threonine residues affects the skin AFPs activity, or ability to prevent ice crystal formation, negatively (Gong). These findings are important to pull together an understanding of the evolution in AFPs. For one, several different isoforms of the same protein suggests that there is a gene family (Gong)....

- ... In most people, the growth, dying, and shedding of skin happens without being detected , people with Ichtyosis Vulgaris create new skin cells at a faster rate than they can actually shed it, or even attempt to replicate at a normal rate. When that is happening there is just one huge buildup of dry skin. The mutated gene in Ichtyosis Vulgaris is located on chromosome Iq21 and is related to a protein called filaggrin. Ichtyosis Vulgaris has altered filaggrin expression that leads to scaling and desquamation.... [tags: inhereted skin conditions]

- Analysis of proteins found in varying fish muscle Introduction Gel electrophoresis involves separation and analysis of macromolecules like deoxyribonucleic acid (DNA), ribonucleic acid (RNA), and various proteins. In electrophoresis an electric current is passed through a solution or gel from one electrode to the other. Ions, molecules, and molecular fragments in the solution or gel are drawn to one of the electrodes according to their charge. When charged molecules are placed in a gel, the speed they travel toward the electrode is influenced by both their charge and size.... [tags: Protein, Molecular biology, Western blot]

- Fish protein has been a mainstay for the human diet for centuries. However, aquaculture, which is the practice of raising fish such as salmon in controlled conditions, as opposed to the commercial fishing industry, which is procurement of wild fish from their natural environment, made its debut in the United States as a commercial enterprise in the late 1970’s according to the Eco - Justice Marketplace Project.(n.d.). This mode of salmon procurement began to develop in the late eighteenth and early nineteenth century, as a response to the declining populations of native wild fish such as salmon and trout....

- The objective of this study was to determine how temperature affects the activity level of the Cepaea nemoralis. Both experiments showed the same relative trend of increased movement in a warm environment as opposed to decreased movement in a cold environment. Both trials had a much greater mean distance travelled over one minute in the warm environment than they did in the cold environment. However, many snails displayed no activity in the cold environment by retracting into their shells and whenever fresh hot water was added to the hot treatment to keep the temperature stable, the snails would get agitated and begin to crawl up the walls of the glass bowl....

- Proteins are fundamental components of all living cells that participate in some of the most important biological processes, including cell growth and maintenance, movement and defense. They are complex molecules that consist of one or more chains of amino-acids, have distinct three-dimensional shapes and whose structure and structural dynamics directly influence their specific function. Most proteins have a primary, secondary and tertiary structure, but some of them, like hemoglobin, also have a quaternary structure.... [tags: Proteins, Structures, Functions]

- The Effects of Increased Temperature on Fish Reproduction Today, many factors can contribute to an unexpected increase in temperature in streams, ponds, lakes and even oceans. One of the many factors which may cause this is a nuclear power plant. Although many might think that nuclear power is a source of many pollutants, this has been proven not to be so (1). In fact, nuclear power plants only cause one pollutant to the nearby water bodies, increased temperature. Usually this increase in temperature is approximately ten degrees above normal (2)....

- Temperature Temperature affects various processes in the water quality (ANZECC 1992). The rate of chemical reactions, for example, is activated when high water temperature occurs which causes evaporation of certain substances that may be present in the water. Also, as water temperature increases, the solubility rate of gases in water, such as oxygen (O2), decreases and respiration rates of aquatic organisms increases which results to greater oxygen consumption (Chapman and Kimstach 1992). A change in water temperature also causes greater destruction of aquatic life and problem of unwanted growth of water plants and wastewater fungus (Metcalf and Eddy 1991)....

- Saving Nemo Fish keeping may seem like a fun and easy hobby, but without the proper research and knowledge one will kill the fish rather than keep them. Most people think keeping fish is an easy hobby because all you have to do is buy a tank and the fish to put in the tank, but they are extremely wrong. Fish are very hard to care for, and they are also very temperamental to changes within the tank. Fish require constant care and a watchful eye of the water conditions in the tank. If the water condidtions in the tank are not set up properly, or if there is a spike or sudden change in the water conditions it could cause the fish to become sick or even kill the fish....

- Proteins Proteins are the macromolecules of life. Discovered in 1838, proteins are recognized as a large number of superior organic compounds that make up living organisms and are essential to their functioning. The term protein comes from the Greek word “proteies” or “primary”. Proteins have many different properties and function in a variety of ways. They can function as a building material, in teeth, bones and muscles, and they can serve as enzymes, hormones, and neurotransmitters. Its functions are the most diverse of any family....
