Lake Kanyaboli
Lake Kanyaboli is a lake in the Yala Swamp in western Kenya. It is important as a refuge for fish species that have almost disappeared from Lake Victoria. Location The Yala Swamp at the mouth of the Yala River covers about along the northern shore of Lake Victoria. The swamp contains the Lake Kanyaboli, a freshwater deltaic wetland with an average depth of , which is fed by the floodwaters of the Nzoia and Yala rivers and by the backflow of water from Lake Victoria. In the past the Yala River flowed through the eastern 20% of the Yala Swamp into Lake Kanyaboli, then into the main swamp, and then through a small gulf into Lake Victoria. Today the eastern part of the swamp has been drained, and the river flows directly into the main swamp. It is cut off from Lake Kanyaboli by a silt-clay dyke. Lake Kanyaboli now receives its water from the surrounding catchment area and from back-seepage from the swamp. Ecological value Lake Kanyaboli provides a refuge for several species of ...

Yala Swamp
The Yala Swamp is a wetland region of about in Western Kenya. Location The Yala Swamp at the mouth of the Yala River covers about along the northeastern shore of Lake Victoria. The swamp contains the Lake Kanyaboli, a freshwater deltaic wetland with an average depth of , which is fed by the floodwaters of the Nzoia and Yala rivers and by the backflow of water from Lake Victoria. The wetland is in Siaya and Busia counties in Kenya. It acts as a filter for waters that flow into Lake Victoria from two major rivers, the Yala River and Nzoia River. It is sometimes considered the source of the Nile. In the past the Yala River flowed through the eastern 20% of the Yala Swamp into Lake Kanyaboli, then into the main swamp, and then through a small gulf into Lake Victoria.

Nzoia River
The Nzoia River is a Kenyan river, rising from Cherangany hills. It passes through Kapsara, Springer ,Moi's bridge then crosses to Kakamega county.It flows south and then west, eventually flowing into Lake Victoria near the town of Port Victoria. The river has a discharge of about 118 m3/s or about 3,721 million cubic metres annually, making it the second biggest river in the country by discharge. The river is important to Western Kenya, flowing through a region estimated to be populated by over 3.5 million people. Its waters provide irrigation all year round, while the annual floods around the lowland area of Budalang'i deposit sediment that contributes to the area's good agricultural production. Around the industrial region centred at Webuye, the river absorbs a lot of effluent from the paper and sugar factories in the area. The river has a number of spectacular waterfalls, and is thought to possess good hydroelectricity generation potential. The river experiences annual ...

Nile Perch
The Nile perch (''Lates niloticus''), also known as the African snook, Goliath perch, African barramundi , Goliath barramundi, Giant lates or the Victoria perch, is a species of freshwater fish in family Latidae of order Perciformes. It is widespread throughout much of the Afrotropical realm, being native to the Congo, Nile, Senegal, Niger and Lake Chad, Volta, Lake Turkana, and other river basins. It also occurs in the brackish waters of Lake Maryut in Egypt. The Nile perch is a fish of substantial economic and food-security importance in East Africa. Originally described as ''Labrus niloticus,'' among the marine wrasses, the species has also been referred to as ''Centropomus niloticus''. Common names include African snook, Victoria perch (a misleading trade name, as the species is not native to Lake Victoria, though they have been introduced there), and many local names in various African languages, such as the Luo name ''mbuta'' or ''mputa''. In Tanzania, it is called '' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Nile Tilapia
The Nile tilapia (''Oreochromis niloticus'') is a species of tilapia, a cichlid fish native to the northern half of Africa and the Levante area, including Israel, and Lebanon. Numerous introduced populations exist outside its natural range. It is also commercially known as mango fish, nilotica, or boulti. The first name leads to easy confusion with another tilapia which is traded commercially, the mango tilapia (''Sarotherodon galilaeus''). Description The Nile tilapia reaches up to in length, and can exceed . As typical of tilapia, males reach a larger size and grow faster than females. Wild, natural-type Nile tilapias are brownish or grayish overall, often with indistinct banding on their body, and the tail is vertically striped. When breeding, males become reddish, especially on their fins. Although commonly confused with the blue tilapia (''O. aureus''), that species lacks the striped tail pattern, has a red edge to the dorsal fin (this edge is gray or black in Nile tilap ...

World Conservation Union
The International Union for Conservation of Nature (IUCN; officially International Union for Conservation of Nature and Natural Resources) is an international organization working in the field of nature conservation and sustainable use of natural resources. It is involved in data gathering and analysis, research, field projects, advocacy, and education. IUCN's mission is to "influence, encourage and assist societies throughout the world to conserve nature and to ensure that any use of natural resources is equitable and ecologically sustainable". Over the past decades, IUCN has widened its focus beyond conservation ecology and now incorporates issues related to sustainable development in its projects. IUCN does not itself aim to mobilize the public in support of nature conservation. It tries to influence the actions of governments, business and other stakeholders by providing information and advice and through building partnerships. The organization is best known to the wider pu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Haplochromis
''Haplochromis'' is a ray-finned fish genus in the family Cichlidae. It has been used as the default "wastebin taxon" for Pseudocrenilabrinae cichlids of the East African Rift, and as such became the "largest" fish "genus". Many of these cichlids are popular aquarium fishes; like similar Haplochromini they are known as "haplos", "happies" or "haps" among aquarium enthusiasts. The genus was established by F.M. Hilgendorf in 1888. It was originally conceived as a subgenus of A.C.L.G. Günther's ''"Chromis"'', at that time an even larger "wastebin genus" for Pseudocrenilabrinae cichlids. The type species of Hilgendorf was '' H. obliquidens''. ''"Chromis"'' of Günther turned out to be a junior homonym of G. Cuvier's ocean fish genus '' Chromis'', already established in 1814, and was abolished. As the years went by, other genera of (mostly) Haplochromini were lumped with and split again from ''Haplochromis'', and the final delimitation of the clade around ''H. obliquidens'' is not ...

Oreochromis Esculentus
''Oreochromis esculentus'', the Singida tilapia or Graham's tilapia, is a 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''. In 1927-1928 Michael Graham conducted the first ever systematic Fisheries Survey of Lake Victoria. In his official report of the expedition, Graham wrote that "The ngege or satu ''Tilapia esculenta'', is the most important food fish of the lake, whether for native or non-native consumption. No other fish equals it in the quality of the flesh. It is convenient size for trade, travels well and is found in much greater numbers than other important fish, such as semutundu (Luganda), ''Bagrus sp.'.Graham M. (1929.)

Oreochromis Variabilis
''Oreochromis variabilis'', the Victoria tilapia, is a 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 . This species is important to local commercial fisheries and is potentially important in aquaculture. It is also found in the aquarium trade. Despite its common name, it is not the only tilapia native to Lake Victoria. The equally threatened '' O. esculentus'' has a similar distribution. Description ''Oreochromis variabilis'' has typical characteristics of a cichlid fish: long dorsal fin with both spiny and soft rays, a broken lateral line, a single pair of nostrils and a single lower pharyngeal bone. Like other typical 'tilapias', it has relatively small closely packed teeth, numerous gill rakers and juveniles have a dark 'tilapia spot' at the base of the soft-rayed part of the dorsal f ...
