The Malagarasi is a river in East Africa. Its source is in Tanzania ( Kigoma Region ) near the border with Burundi, about 50 km northeast of Lake Tanganyika at an altitude of 1650 meters. He turns first to the north-east away from Lake Tanganyika to form at about 110 km, the border between Tanzania and Burundi, and then, then return in a big bow first to the south in western direction to him. It has a length of 475 kilometers. About 80 kilometers before reaching the confluence with Lake Tanganyika, 45 km south of the port town of Kigoma, the Malagarasi is dammed by pressed upward edge clods of the Rift Valley, forming an extensive marshland ( Malangarasi - Moyowosi swamps ), in which the flow of a large part the entrained sediment and organic materials deposited. The marshes are 1200 meters above the sea and occupy an area of 3.25 million hectares, of which 250,000 lakes and marshes that lead even during the dry season. The swamp area was included in the Ramsar Convention for the protection of wetlands. The landscape in the catchment area of ​​the Malagarasi is determined by miombo woodland savanna type ( tree savanna ).

The catchment area of ​​130,000 square kilometers includes Malagarasi. The annual amount of water is measured at Mberagule with 6.9 cubic kilometers; he thus represents next to the Ruzizi represents the most important tributary of Lake Tanganyika

Fauna

The fauna of the Malagarasi is determined by the change in fast flowing sections with considerable slope in the headwaters and at the edge of the East African Rift and the almost stagnant water in the swamp zones. In the flowing areas live cichlids as Orthochromis kasuluensis, O. and O. rubrolabialis uvinzae, also African catfish ( Chiloglanis ) and various cyprinids of the genera Opsaridium and Raiamas, that represents about the ecological role of European trout here. In the calmer stretches of water larger cichlids are found in the genus Oreochromis. The season fishes of the genus Nothobranchius and the lung fish can survive even drying of the waters as a kind, former latter by survive by resting eggs that they have laid before the dry out the soil, the drying time in a cocoon in the soil. The most important for human consumption of fish Malagarasi are the one meter long expectant Clarias gariepinus catfish and big tilapia Oreochromis Malagarasi. Overall, the Malagarasi is inhabited by 108 species belonging to 48 genera from 20 families of fish. Of these species, 15% of a Congolese origin, 7 % comes from the catchment area of Lake Victoria and the Nile.
