Lake Victoria

Lake Victoria in the East African Rift Valley is young compared to the surrounding lakes in the region. Despite this, the haplochromine cichlid fish that inhabit this lake have shown rapid evolution. The lake was formed by a combination of tectonic movement and river water reversal of an “ancient drainage system” in the Pleistocene. The lake is also shallow compared to others in the area (a maximum depth of 69 meters), so it is unlikely that the resident cichlids could have survived in pools during

invasive species in just about any lake it is introduced into. It is a great food fish and is also popular to fisherman because it attacks attacks fishing lures. Literature Review Before being introduced into lake Victoria, the Nile Perch was mainly found spread out over the Afrotropic ecozone. It is native to many river basins as in lake Chad and the Nile river it was also found in Lake Maryut in the northern part of Egypt. The Nile was introduced to Lake Victoria to try and help boost the fishing

a freshwater fish native to Lake Albert and Lake Turkana (Global Invasive Species Database). They have been an invasive species since they have been swimming in Lake Victoria. This species was introduced in 1954 (Global Invasive Species Database). The reason why the Nile perch was introduced was to gain back population (Lowe). Lake Victoria’s Native population was being overfished (Lowe). In the 1980s the Nile perch population dominated three quarters of Lake Victoria (Global Invasive Species Database)

outer rings (Animal Planet). The Nile perch is a dominating predatory fish they can both inhabit in fresh and tropical waters, but typically prefers warm tropical waters (Animal Planet). It can be found in lakes and in rivers of central Africa. They have common nicknames like Snook and Victoria Perch. The Nile perch feeds on its own species but also eats insects, crustaceans, and other fish. Old Nile perches feed at the bottom of the river while the young ones feed at the top of the river.

Abstract The Nile Perch is a fish that was introduced to Lake Victoria in Africa in 1954 and it cause the extinction of many fish species.. This paper will discuss the historical background of the Nile Perch, its Taxonomy, and why it was introduced into Lake Victoria as well as the effect it had on the economy and the environment. Historical Background “The Nile perch was introduced to Lake Victoria, Africa in 1954 to counteract the drastic drop in native fish stocks caused by overfishing.” (Browne)

fish is most commonly found in Lake Victoria or they can sometimes be found in the Nile river in Egypt ( Lipton, 2003) (Schofield, 2012). The Nile Perch is a large fish it’s about 6 feet long and weighs 300 pounds ( The editors of Encyclopedia Britannica, 2008). This fish is also known by several different names one including the Victorian Perch due to its location in Lake Victoria. “In the 1950s the Nile Perch was introduced into Lake Victoria to boost the fishing community

Introduction The Sukuma people of northwestern Tanzania, resting on the southern shore of Lake Victoria, have been greatly impacted by the increasing global markets in the region. While the Sukuma are dispersed across Tanzania, those that live near Lake Victoria have greatly changed their ways of living because of the impacts of globalization and the involvement of European countries with fisheries along the Lake. Many of the Sukuma people work for the fisheries that export extremely high quantities

Health Risks Nearly all of the fish caught are prepared and exported to different countries in Europe, and Europeans moved in as the bosses of local people, who are hired to work for low wages (Sauper 2004). Consequently, Europeans brought diseases such as HIV/AIDS which has affected a significant amount of Sukuma in the region (Jangu 2012). Women often become prostitutes, because Europeans flying into Mwanza to pick up the fish would often pay them well for their services. This is common among widows

uncovered as the result of exporting Nile Perch, environmental degradation and pollution are causes for greatest concern. Degradation of the ecosystem Lake Victoria was known as one of the greatest and largest lakes in Africa. Although after understanding the outcomes of the fishing industry, in Tanzania, such a title should be revoked. The lake had an abundant selection of fish calculating up to 400 species. The vast amount of fishes each had a job. For example, the

The Nile River changes as it flows in Africa. The Nile River has two break off points, the Blue and White Nile. Lake Victoria is the headwaters of the Nile. Run-off from the mountains collects in Lake Victoria. Whenever it is raining or the glaciers melt the water drips down the mountain sides. Whenever it rains to much the part of the river will flood. Every year, the waters of the Nile rise and fall with seasons. If the water freezes, there would be no way for the Nile to flood. However, when it
