Kagera River
The Kagera River basin is rich in fish. , there were at least 55 species known from the Rwandan section alone and the actual number is likely higher. Additionally, there are at least 15 undescribed species of haplochromine cichlids that are endemic to some of the lakes in the upper parts of the river basin. Because of the many waterfalls and rapids, the various sections of the Kagera River basin are clearly separated, making movements between them difficult or even impossible to fish.
