The set up of small beaches and local authorities around the lake lack proper sewage treatment facilities allowing pollutants to find their way into the water.

[35] Disregarding the haplochromines, the only native Victoria cichlids are two critically endangered tilapia, the Singida tilapia or ngege (Oreochromis esculentus) and Victoria tilapia (O. Lake Victoria: In terms of surface area, Victoria is the largest lake in Africa and the second largest freshwater lake in the world. Location and features. [25] These changes have arisen for multiple reasons: successive burning within its basin,[26] soot and ash from which has been deposited over the lake's wide area; from increased nutrient inflows via rivers,[27] and from increased pollution associated with settlement along its shores. In addition, it's the largest tropical lake in the world, and the planet's second largest freshwater lake. Lake Baikal is a rift lake in southern Siberia, Russia.

In addition to the biogas it produces, its by-product can be used as fertilizer. [41][78][80] Although these have contributed to the extinction of native fish by causing significant changes to the ecosystem, outcompeted natives and (in the case of the Nile tilapia) possibly hybridized with the highly threatened native tilapias, the most infamous introduction was the large and highly predatory Nile perch (Lates niloticus).
