Lake Bisina
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 extent directly connected by papyrus swamps. During the high-water rainy season, Lake Bisina can be up to deep and it is often directly connected to the smaller Lake Opeta, but during the dry season the two are clearly separated. Conservation and ecology Lake Bisina is one of Uganda's 33 Important Bird Areas and since 2006 a Ramsar-listed wetland of international importance. The lake is important for fish, notably several threatened haplochromine cichlids like '' Haplochromis orthostoma'', '' H. argenteus'' (appears to have disappeared from its main range in Lake Victoria), '' H. latifasciatus'', '' H. lividus'', '' H. martini'' (appears to have disappeared from its main range in Lake Victoria), '' H. maxillaris'', '' H. nubilus'', '' H. parvidens'', '' H. phytophagus'' and a number of undescribed species.

Lake Opeta
Lake Opeta is a lake with an extensive wetland system in Uganda. The wetland lies south of the Pian Upe Wildlife Reserve and serves as a dry-season refuge for both wildlife from the park and domestic cattle of the surrounding Karamajong and Pokot people. Hydrology Lake Opeta is primarily fed by rainfall on Mount Elgon and drains into Lake Kyoga via Lake Bisina. It is surrounded by an extensive swamp and floodplain. Conservation Lake Opeta is one of Uganda's 33 Important Bird Areas and since 2006 a Ramsar-listed wetland of international importance. A Biodiversity and Eco-Tourism Centre funded by the Global Environmental Facility and UNDP serves the lake. Lake Opeta and its surrounding swamps are located in eastern Uganda, 25km north-east of Kumi town. The Ramsar site stands 1,050 m above sea level and covers an area of 68,913 hectares.

Lake Kyoga Complex
A lake is an area filled with water, localized in a basin, surrounded by land, and distinct from any river or other outlet that serves to feed or drain the lake. Lakes lie on land and are not part of the ocean, although, like the much larger oceans, they do form part of the Earth's water cycle. Lakes are distinct from lagoons, which are generally coastal parts of the ocean. Lakes are typically larger and deeper than ponds, which also lie on land, though there are no official or scientific definitions. Lakes can be contrasted with rivers or streams, which usually flow in a channel on land. Most lakes are fed and drained by rivers and streams. Natural lakes are generally found in mountainous areas, rift zones, and areas with ongoing glaciation. Other lakes are found in endorheic basins or along the courses of mature rivers, where a river channel has widened into a basin. Some parts of the world have many lakes formed by the chaotic drainage patterns left over from the last ice ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Mormyridae
The Mormyridae, sometimes called "elephantfish" (more properly freshwater elephantfish), are a family of weakly electric freshwater fish in the order Osteoglossiformes native to Africa. It is by far the largest family in the order with around 200 species. Members of the family can be popular, if challenging, aquarium species. These fish are also known for having large brain size and unusually high intelligence. They are not to be confused with the marine and brackish-water callorhinchid elephantfish (family Callorhinchidae) of Southern Hemisphere oceans. Description and biology The elephantfish are a diverse family, with a wide range of different sizes and shapes. The smallest are just in adult length, while the largest reach up to . They do, however, have a number of unique features in common. Firstly, their cerebellum is greatly enlarged, enabling them to interpret complex bio-electrical signals. and to the large size of the valve, Secondly, an auditory vesicle (a small bla ...

Catfish
Catfish (or catfishes; order Siluriformes or Nematognathi) are a diverse group of ray-finned fish. Named for their prominent barbels, which resemble a cat's whiskers, catfish range in size and behavior from the three largest species alive, the Mekong giant catfish from Southeast Asia, the wels catfish of Eurasia, and the piraíba of South America, to detritivores (species that eat dead material on the bottom), and even to a tiny parasitic species commonly called the candiru, ''Vandellia cirrhosa''. Neither the armour-plated types nor the naked types have scales. Despite their name, not all catfish have prominent barbels or "whiskers". Members of the Siluriformes order are defined by features of the skull and swimbladder. Catfish are of considerable commercial importance; many of the larger species are farmed or fished for food. Many of the smaller species, particularly the genus '' Corydoras'', are important in the aquarium hobby. Many catfish are nocturnal, [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Marbled Lungfish
The marbled lungfish (''Protopterus aethiopicus'') is a lungfish of the family Protopteridae. Also known as the leopard lungfish, it is found in Eastern and Central Africa, as well as the Nile region. At 133 billion base pairs, it has the largest known genome of any vertebrate and one of the largest of any organism, along with ''Polychaos dubium'' and ''Paris japonica'' at 670 billion and 150 billion, respectively. The marbled lungfish is caught in large numbers throughout much of its range, including several hundred metric tonnes per year in the Mwanza Gulf of Lake Victoria alone. It is mostly a food fish, although this varies depending on the exact community, with some recognizing it as a delicacy and others strongly disliking its taste or considering it as a taboo to eat it. In some regions, parts of this fish are used as traditional medicine. Description The marbled lungfish is smooth, elongated, and cylindrical with deeply embedded scales. The tail is very long and has tape ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Victoria Tilapia
''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 ...

Oreochromis Esculentus
''Oreochromis esculentus'', the Singida tilapia or Graham's tilapia, is a species of cichlid Endemism, endemic to the Lake Victoria basin, including some of its satellite lakes such as Lake Kyoga, Kyoga, in Tanzania, Uganda, and Kenya. Its common name refers to Singida#Lake Singida, Lake Singida, but this population is the result of an Introduced species, introduction that happened in the 1950s. This fish is highly valued by local fishermen, who know it as ''ngege''. In 1927-1928 Michael Graham (scientist), 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 ...

Tilapia
Tilapia ( ) is the common name for nearly a hundred species of cichlid fish from the coelotilapine, coptodonine, heterotilapine, oreochromine, pelmatolapiine, and tilapiine tribes (formerly all were "Tilapiini"), with the economically most important species placed in the Coptodonini and Oreochromini. Tilapia are mainly freshwater fish inhabiting shallow streams, ponds, rivers, and lakes, and less commonly found living in brackish water. Historically, they have been of major importance in artisanal fishing in Africa, and they are of increasing importance in aquaculture and aquaponics. Tilapia can become a problematic invasive species in new warm-water habitats such as Australia, whether deliberately or accidentally introduced, but generally not in temperate climates due to their inability to survive in cold water. Tilapia has been the fourth-most consumed fish in the United States since 2002. The popularity of tilapia came about due to its low price, easy preparation, and mi ...

Introduced Species
An introduced species, alien species, exotic species, adventive species, immigrant species, foreign species, non-indigenous species, or non-native species is a species living outside its native distributional range, but which has arrived there by human activity, directly or indirectly, and either deliberately or accidentally. Non-native species can have various effects on the local ecosystem. Introduced species that become established and spread beyond the place of introduction are considered naturalized. The process of human-caused introduction is distinguished from biological colonization, in which species spread to new areas through "natural" (non-human) means such as storms and rafting. The Latin expression neobiota captures the characteristic that these species are ''new'' biota to their environment in terms of established biological network (e.g. food web) relationships. Neobiota can further be divided into neozoa (also: neozoons, sing. neozoon, i.e. animals) and n ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
