However, their problems just got worse. In 1990, a plant called a water hyacinth was first introduced into Africa as an ornamental flower, but this plant grows very quickly. It covered ninety percent of the lake's shores, and also blocked the light and oxygen from the lake.
The water hyacinth causes even more problems. Fishing boats couldn’t get through the plant because it was so overgrown and thick. It also is causing problems for Uganda's capital, Kampala, because it would clog the filters for the region's main hydroelectric generating system. Also, where the plant would grow, mosquitos, snakes, and snails would gather there and the mosquitos would spread diseases like malaria.
Overall, Lake Victoria has been through bad disruptions of the food web. Because of this, it will take tremendous amounts of resources to fix it. Cichlids are being kept in aquariums around the world, so if they could ever be reintroduced into the lake, they would be there. As long as the Nile Perch industry was doing well, the government won’t interfere with it. This experience should show us to take better interest and care about what happens to and in our great lakes.
