Abstract The economy, social, and politics led the introduction of species. The non native nile perch in Lake Victoria drew a lot of attention from biologists. In the 1950s there was a bunch of introductions made by a group of The Uganda Game and Fisheries Department they wanted to improve sport fishing and bolster the economy of fishing (Pringle 2005). While observing the fish, they saw that it increased the economic value of the fishery (Pringle 2005). When the fish invaded Lake Victoria, it caused the extinction of more than 200 different kinds of fish. “The nile perch also made changes in the tropical function and diversity of the lake” (Schofield 2011). Not only was Lake Victoria affected, but other lakes as well. General Characteristics The nile perch found in central, eastern, and western of Africa. “Nile Perch is also found in the brackish Lake Marriott near Alexandria Egypt” (Schofield 2011). This is known as the Lates niloticus it comes from the family Centropomidae. “The nile perch is a greenish or brownish above and silvery below, it grows about 6 feet and weighs about 300 pounds” (The Editors of Encyclopedia). There breeding season time is around March to June and the female gives off about 9 million offsprings, but the majority don’t survive to maturity (Nile Perch 2014). The nile perch is carnivore meaning they eat other fish for example, crustaceans, insects, and the juveniles eat zooplankton. Nile perch can also be cannibal, meaning they eat their flesh of its species (Society 2015). They adjust easily to its feeding habitats, adapts to a new environment, and prey resources. It also occupies in a bunch of different habitats, including rivers, lakes, and irrigation channels (Schofield 2011). Impact of the Nile Perch When the nile perch is in Lake Victoria it affected many areas around the lake. For example, local fishing and deforestation, because the fish had to be smoked and fried, it leads to a distribution of fuelwood shortages and deforestation around the lakeshore (Fisheries and Agricultural Department). These shortages are caused by the growth of the nile perch fisheries. Also, it had an enormous loss to evolutionary biology (Fisheries and Agricultural Department). In Lake Victoria had several cichlid species, that helped other fishes grow, as well the economy in the local areas that surrounded the lake. The cichlid is a fish that lives in the waters of Lake Victoria and it became to disappear and decrease. The nile perch became the most fish to catch in Lake Victoria, but it also became the most invasive fish. The fish has overtaken the lake for more than half of century. (McDonell 2015). Not only did the fish overtake, but it made the climate change over the years. This fish has affected the temperature gradually in Lake Victoria, Lake Tanganyika, and Lake Malawi, which is located in Africa (McDonell 2015). DiscussionThe introduction of the nile perch in Lake Victoria was not a good idea, it became an invasive species very quickly in the lake. They have caused many damages in other lakes in Africa, but not just in Africa, some lakes in Egypt were affected too. It caused other fish population to decrease, and some native fish in the lakes may have gone extinct. It affected local fishermen and the economy. The nile perch at a time affected the people who worked as a fisherman, some of them were laid off due to the nile perch. They were almost introduced into one of Russia’s lake or rivers, but they saw how these fish affected Lake Victoria they decided to stop the process because they did not want to damage the lake, and the species that live in it; as we can see these invasive fish was a bad introduction in Lake Victoria.
