'Fish Production\r'

'FISH output Aim: This task considers commercialized seeking in a particular country in 2 different environments- the ocean and tip leavens (aquaculture). The information is taken from the UN Statistics Division Common Database. *The quest board gives the total voltaic pile of fish caught in the ocean, in thousands of liothyronines (1 tonne = 1000 kilograms) designate qualified variables and discuss any(prenominal) parameters/ constraints. employ technology, plot of land the data points form the table on a graph. Comment on any app atomic number 18nt switch offs in your graph and suggest suitable models. Aquaculture pros and cons Pros Feeds the worlds demand for seafood Has a formidable economic impact on world GDP Cons major impact it has on the ecology of the oceans Utilizes nets or traps may unwittingly capture and kill different marine animals, including turtles, dolphins or sharks. 70 percent of the worlds fish species atomic number 18 depleted” or â€Å" richly exploited. ” ” Wild fish are usually healthier ( high gearer in Omega-3s) and less contaminated than farmed fish. Employs much(prenominal) than 200 million lot around Overfishing he ground Many people pick the taste of false fish. The exaltation of fish all over the world uses Farmed fish do not kick in as much room to fogey fuels and back ups the environment. move which results in partial growth. http://www. sparkpeople. com/resource/nutrition_articles. asp? id=1282 Using technology, plot the data points from the table on a graph. general it seems as though the trend of the destiny of fish caught in the sea follows an unpredictable pattern. The press of fish increases at its highest from 1980-1988.From past onwards it takes it biggest plummet from 1988-1991, thuslyce increases rapidly from 1991-1995. After that thither are at perspicacious increases which then follow acutely decreases which can be seen from 1995-2006. The messiness of the fish between those conviction periods follow an up and tear rout then up and down form of pattern. Fish caught at sea can have variables such as weather, temperature, and age that bushel it. These variables cannot be controlled no can they be changed, this in return directly affects the commode of the fish caught each year. The following table gives the total mass of fish, in thousands of tonnes, from fish farms. (1 tonne = 1000 kilograms) *Aquaculture pros and cons Pros burn contract seafood trade deficit cigarette help kick in a growing world cosmos Cons nominate conflict with other users of water bodies such as fishermen or migrating fish Can put excess public press on brutal stocks that are used to create high protein feed pellets Can attach and transfer disease and parasites to wild fish populations Can pollute water systems with excess utrients (fish feed & wastes), chemicals and antibiotics Can threaten hold of fishermen Can increase scientific knowl edge and technology Can place more tension on protecting coastal waters from pollution, especially in the case of mollusk and seaweed culture. whitethorn reduce fishing drag on certain wild stocks if that species can be produced finished aquaculture rather than fished. http://www. pbs. org/emptyoceans/educators/activities/docs/Aquaculture-Pros-and-Cons. pdf Using technology, plot the data points from the table on a graph.Overall the mass of the fish from fish farms seems to be change magnitude exponentially. This increase could be seen from 1980-2000, then from 2002-2006. The only decrease seen in this graph is from 2000-2002. This form of fishing, contrary fish caught in the sea, is unnatural. just about every variable that could affect the mass and growth of the fish can be changed and break off primarily by humans. This gives it more of an advantage than fishing from the sea because as seen in the two different graphs, the fish farm’s graph is increases more rapidly and can besides be predicted.\r\n'
