A naturally occurring environmental phenomenon that derives from the Pacific Oceans eastern part rigorous to South America, El Nio has the capability to greatly interchange and disturb the stick out patterns of the world (El Nio, 1998). With the English interlingual rendition of The Child, El Nio poses a great buy of disruption to fishing for a lengthy time. While the pees of Australias westbound field appears to be quite a distance outside(a) from South Americas coast, the El Nio has its liaison make on the local fishing catches of Australian fisherman. The reason shtup much(prenominal) a stri tabby effect even at such a great distance is largely because of the Leeuwin menstruum, the tropical live that flows in the south.The Leeuwin Current is responsible for transporting tropical water that is warm towards the south close to the continental shelf of the Western Australian coastal region (The Leeuwin Current, 2005). The flow is also accountable for the subsistence of coral reefs as well as the construction of tropical species at the island of Rottnest as well as the area of the southerly coast.The rest of the currents traversing the Pacific as well as the Atlantic Oceans in the eastern side of the southern hemisphere differ to that of the Leeuwin Current. The Leeuwin Current varies to those of the Benguela and Humboldt Currents in the sense that the latter bring to the north cold waters from the south. Since the Leeuwin Current is composed of clear, low-nutrient and warm water that do not support the beingness of huge numbers of finfish, the current results to the production of huge numbers of namby-pamby animals which include prawns as well as rock lobsters.During the months of winter and fall from April to September, the Leeuwin Currents flow is at its peak where the temperature of the surface of the sea are shown in the National Oceanic and Atmospheric Administration (NOAA) beam images as a warm flow of water to the south gain up to the speeds of more than 3 knots and with the average speed running at about 1 knot.El Nio periods have a air impact on the strength of the Leeuwin Current which correspondingly affects the biological sort and fisheries of Western Australia (Caputi, Fletcher, Chubb, Joll, & Pearce, 1997). More specifically, the Leeuwin Current influences the degree of catches of western rock lobsters since the current at present affects the 11 month journey of these lobsters during their early stage as planktons drifting in the currents of the ocean that settle on the inshore coastal regions after.For the duration of an El Nio time, tropical rains typically center over Indonesia move towards the east, swaying atmospheric wind schemes globally (Diaz & Markgraf, 1994). Probable effects consist of a changing of the jet stream, hurricane tracks and heavy shower, creating unseasonable weather conditions in numerous areas of the world.Hence, as atmospheric wind patterns and oceanic water flows are alt ered by the El Nio, the Leeuwin Current is directly affected as well. The major alteration is evident in the slip of the flow of the Leeuwin Current, thus, correspondingly changing the proliferation and the emergence of numerous aquatic animals reliant on the current. Some of these include the western rock lobsters, scallops, western king prawn, pilchards, whitebait, and the Australian salmon and herring (Holloway, 1995). All of these marine animals are lush in the fisheries of Western Australia. Thus, an alteration in the Leeuwin Current caused by El Nio greatly affects the population of these aquatic animals in the western region of Australia.Since biological diversity entails the balance and the interrelation among the various species of animals, a change such as an increase or a pass in the population of a specific species of marine animals within the region of Western Australia causes an imbalance in the overall marine biological diversity.ReferencesEl Nio.
