Lake Victoria is one of the African Great Lakes.
Lake Kyoga is a large shallow lake in Uganda, about 1,720 km2 (660 sq mi) in area and at an elevation of 1,033 metres. The Victoria Nile flows through the lake on its way from Lake Victoria to Lake Albert. The main inflow from Lake Victoria is regulated by the Nalubaale Power Station in Jinja. Another source of water is the Mount Elgon region on the border between Uganda and Kenya. While Lake Kyoga is part of the African Great Lakes system, it is not itself considered a great lake.
Copadichromis borleyi is a species of haplochromine cichlid fish endemic to Lake Malawi in East Africa. The species is popular in the fishkeeping hobby where it is frequently kept in aquariums. The species has numerous common names, including redfin hap and goldfin hap.
Haplochromis welcommei is a threatened species of cichlid endemic to Lake Victoria in Africa. This species reaches a length of 10.5 centimetres (4.1 in) SL. Although further surveys are needed to confirm its status, it is considered possibly extinct by the IUCN on the basis that there have been no definite records since 1985.
Haplochromis argenteus is a critically endangered species of cichlid fish that is endemic to the Lake Victoria system in Africa. This species reaches a standard length of 20.2 cm (8.0 in). The species declined rapidly after the Nile perch was introduced to Lake Victoria. Last reported from this lake in 1983, it was considered possibly extinct when evaluated by the IUCN in 2010. However, that same year, several were recorded during a fish survey of Lake Bisina, a satellite lake of Lake Kyoga.
Haplochromis elegans is a species of cichlid endemic to Uganda where it occurs in Lake George, Lake Edward and the Kazinga Channel. This species can reach a length of 7.3 centimetres (2.9 in) SL.
Astatotilapia flaviijosephi, the Jordan mouthbrooder, is a vulnerable species of freshwater fish in the family Cichlidae (cichlids). It is found in the central Jordan River system, including Lake Tiberias (Kinneret), in Israel, Jordan and Syria, making it the only haplochromine cichlid to naturally range outside of Africa. This species is too small to be of significant importance to fisheries, unlike the only other cichlids native to the Levant, the economically important tilapias.
Haplochromis latifasciatus is a species of cichlid that is endemic to Uganda where restricted to the Lake Kyoga system, including Lake Bisina and Lake Nawampasa. This fish can reach a total length of 11 cm (4.3 in). It is also seen in the aquarium trade and it is easily bred in captivity. In the aquarium trade it is frequently labelled as Haplochromis "zebra obliquidens", which sometimes cause confusion with Haplochromis obliquidens, a separate species from Lake Victoria that is not known from the aquarium trade.
Haplochromis martini is a critically endangered species of cichlid fish that is endemic to the Lake Victoria system in Africa. It reaches a standard length of 10.4 cm (4.1 in). The species declined rapidly after the Nile perch was introduced to Lake Victoria. Last reported from this lake in 1985, it was considered possibly extinct when evaluated by the IUCN in 2010. However, that same year, it was recorded during a fish survey of Lake Bisina, a satellite lake of Lake Kyoga.
Haplochromis obliquidens is an African species of cichlid found in Lake Victoria and the adjacent reaches of the Nile. This species can reach a standard length of 8.9 cm (3.5 in). Another species sometimes seen in the aquarium trade, Haplochromis latifasciatus of the Lake Kyoga system, is frequently labelled as Haplochromis "zebra obliquidens", which sometimes cause confusion between the species. Unlike that species, H. obliquidens is not known from the aquarium trade.
Haplochromis pyrrhocephalus is a species of cichlid fish endemic to Lake Victoria in East Africa. This species can reach a standard length of 7.3 cm (2.9 in).
Haplochromis worthingtoni is a species of cichlid endemic to Lake Kyoga in Uganda. This species reaches a length of 14.1 centimetres (5.6 in) SL. The specific name honours the explorer E. Barton Worthington (1905-2001) who collected the type of this species with type with Michael Graham.
Haplochromis nigricans is a species of cichlid endemic to Lake Victoria where it is known only known with certainty from Entebbe, Uganda, other populations now placed in H. rufocaudalis. Its preferred habitat is shallow waters with rocky substrates. This species can reach a length of 9.4 centimetres (3.7 in) SL.
Haplochromis simotes is a species of cichlid endemic to the Victorian Nile where it is only known with certainty from Kakindu and questionable records from Ripon Falls, both in Uganda. This species can reach a standard length of 8.7 cm (3.4 in). This algae-feeder is found in fast-flowing waters over a rocky bottom. Although rated as data deficient by the IUCN, its range is very small and it could easily become extinct as a result of already-planned dams.
The striped nothobranch is a species of freshwater fish of East Africa, belonging to the family Aplocheilidae.
Oreochromis esculentus, the Singida tilapia or Graham's tilapia, is a critically endangered species of cichlid endemic to the Lake Victoria basin, including some of its satellite lakes such as Kyoga, in Tanzania, Uganda, and Kenya. Its common name refers to Lake Singida, but this population is the result of an introduction that happened in the 1950s. This fish is highly valued by local fishermen, who know it as ngege.
Oreochromis variabilis, the Victoria tilapia, is a critically endangered species of African cichlid native to Lake Victoria and its tributaries, Lake Kyoga, Lake Kwania, and Lake Bisina (Salisbury), as well as being found in the Victoria Nile above Murchison Falls. This species can reach a standard length of 30 cm (12 in). This species is important to local commercial fisheries and is potentially important in aquaculture. It is also found in the aquarium trade.
The electric blue hap is a species of cichlid fish endemic to Lake Malawi. It prefers to live in caves and crevices in rocky substrates. This species can reach a length of 20 centimetres (7.9 in) TL. It can also be found in the aquarium trade.
Lake Bisina, also known as Lake Salisbury, is a freshwater lake in eastern Uganda. It is a satellite lake of Lake Kyoga, which it drains into and the two are to some extend directly connected by papyrus swamps. During the high-water rainy season, Lake Bisina can be up to 6 m (20 ft) deep and it is often directly connected to the smaller Lake Opeta, but during the dry season the two are clearly separated.
Haplochromis vonlinnei is a species of cichlid endemic to Lake Victoria. It is greyish in color with a distinct mid-lateral band, and a rather slender shape. It feeds mainly on smaller fish. This species can reach a length of 15.9 centimetres (6.3 in) SL. The population of the species has declined due to the introduction of the Nile perch in the 1950s. It has not been recorded since 1980 and the IUCN lists it as "Critically Endangered" and considers it may already be extinct. This fish is named in honour of the Swedish naturalist, Carl Linnaeus.
