Lake Tana is the largest lake in Ethiopia and a source of the Blue Nile. Located in Amhara Region in the north-western Ethiopian Highlands, the lake is approximately 84 kilometres long and 66 kilometres wide, with a maximum depth of 15 metres, and an elevation of 1,788 metres. Lake Tana is fed by the Gilgel Abay, Reb and Gumara rivers. Its surface area ranges from 3,000 to 3,500 square kilometres, depending on season and rainfall. The lake level has been regulated since the construction of the control weir where the lake discharges into the Blue Nile. This controls the flow to the Blue Nile Falls and hydro-power station.
The Ripon barbel is an East African ray-finned fish species in the family Cyprinidae. A notably large barb, its maximum recorded total length is 90 cm (35 in).
Labeobarbus intermedius is an East African ray-finned fish species in the family Cyprinidae. Like the closely related yellowfish, it is hexaploid. A large species, the maximum recorded standard length is nearly 50 cm (20 in). This species has a subspecies named Labeobarbus intermedius intermedius.
Labeobarbus microbarbis is an extinct species of cyprinid fish. It was endemic to Lake Luhondo in Rwanda.
The giant Atlas barbel was a ray-finned fish species in the family Cyprinidae. It is now thought to be extinct.
Labeoninae is a doubtfully distinct subfamily of ray-finned fishes in the family Cyprinidae of order Cypriniformes. They inhabit fresh water and the largest species richness is in the region around southern China, but there are also species elsewhere in Asia, and some members of Garra and Labeo are from Africa. They are a generally very apomorphic group, perhaps the most "advanced" of the Cyprinidae. A common name for these fishes is labeonins or labeoins.
Labeobarbus is a mid-sized ray-finned fish genus in the family Cyprinidae. Its species are widely distributed throughout eastern Africa and especially southern Africa, but also in Lake Tana in Ethiopia. A common name, in particular for the southern species, is yellowfish. The scientific name refers to the fact that these large barbs recall the fairly closely related "carps" in the genus Labeo in size and shape. As far as can be told, all Labeobarbus species are hexaploid. One species, L. microbarbis from Rwanda, is known to have gone extinct in recent times.
