Rubondo Island National Park is an island park with an area of 457 square kilometres. It is located in northwest Tanzania, 150 kilometres west of Mwanza. It includes nine smaller islands. It is in the lacustrine wetland ecosystem on the shores of the Lake Victoria. Known as a “water wonderland”, it is fish breeding ground; tilapia, yellow-spotted otters and Nile perch (as heavy as 100 kilograms) are some of the special species.
Mammal species abound in this remote and not easily accessible park and consist of indigenous species of hippos, vervet monkeys, genets and mongooses, which coexist with introduced species of chimpanzee, black-and-white colobus, elephant and giraffe, bushbucks, shaggy-coated aquatic sitatunga. Fish eagles are seen near the bay and so also crocodiles.
