Notwane River
The Notwane River (or Ngotwane River) is a river in southeastern Botswana. Certain sections of its course form the international boundary with South Africa. Its mouth is at the head of the Limpopo River. It has a catchment area of 18,053 square kilometers. Course The Notwane rises about south of Ramotswa, and runs along the border in a northeast direction to enter the Limpopo at the same longitude as Mahalapye. The Notwane has its source in the sandveld, at the eastern fringes of the Kalahari Desert. It flows roughly northeastwards past the most densely populated area of Botswana, passing east of Lobatse, between the city of Gaborone and Tlokweng village and then through Mochudi village. Finally it joins the left bank of the Limpopo River at the border with South Africa, just 6 km short of the confluence of the Limpopo with the Matlabas River. The Notwane basin is drained by the Notwane itself and its tributaries the Taung, Segoditshane, Metsimotlhabe, Metsemaswaane and ...

Botswana
Botswana (, ), officially the Republic of Botswana ( tn, Lefatshe la Botswana, label=Setswana, ), is a landlocked country in Southern Africa. Botswana is topographically flat, with approximately 70 percent of its territory being the Kalahari Desert. It is bordered by South Africa to the south and southeast, Namibia to the west and north, and Zimbabwe to the northeast. It is connected to Zambia across the short Zambezi River border by the Kazungula Bridge. A country of slightly over 2.3 million people, Botswana is one of the most sparsely populated countries in the world. About 11.6 percent of the population lives in the capital and largest city, Gaborone. Formerly one of the world's poorest countries—with a GDP per capita of about US$70 per year in the late 1960s—it has since transformed itself into an upper-middle-income country, with one of the world's fastest-growing economies. Modern-day humans first inhabited the country over 200,000 years ago. The Tswana ethnic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carp
Carp are various species of oily freshwater fish from the family Cyprinidae, a very large group of fish native to Europe and Asia. While carp is consumed in many parts of the world, they are generally considered an invasive species in parts of Africa, Australia and most of the United States. Biology The cypriniformes (family Cyprinidae) are traditionally grouped with the Characiformes, Siluriformes, and Gymnotiformes to create the superorder Ostariophysi, since these groups share some common features. These features include being found predominantly in fresh water and possessing Weberian ossicles, an anatomical structure derived from the first five anterior-most vertebrae, and their corresponding ribs and neural crests. The third anterior-most pair of ribs is in contact with the extension of the labyrinth and the posterior with the swim bladder. The function is poorly understood, but this structure is presumed to take part in the transmission of vibrations from the swim bl ...

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 ...

Bream
Bream ( ) are species of freshwater and marine fish belonging to a variety of genera including ''Abramis'' (e.g., ''A. brama'', the common bream), ''Acanthopagrus'', '' Argyrops'', ''Blicca'', '' Brama'', ''Chilotilapia'', '' Etelis'', ''Lepomis'', ''Gymnocranius'', '' Lethrinus'', ''Nemipterus'', ''Pharyngochromis'', ''Rhabdosargus'', ''Scolopsis'', or ''Serranochromis''. Although species from all of these genera are called "bream", the term does not imply a degree of relatedness between them. Fish termed "bream" tend to be narrow, deep-bodied species. The name is a derivation of the Middle English word ''breme'', of Old French origin. The term sea bream is sometimes used for gilt-head bream (''Sparus aurata''), (''orata'' in Italy, ''dorada'' in Spain) or porgies (both family Sparidae) or pomfrets (family Bramidae) . See also * Porgie fishing * Bluegill The bluegill (''Lepomis macrochirus''), sometimes referred to as "bream", "brim", "sunny", or "copper nose" as is c ...

African Sharptooth Catfish
''Clarias gariepinus'' or African sharptooth catfish is a species of catfish of the family Clariidae, the airbreathing catfishes. Distribution They are found throughout Africa and the Middle East, and live in freshwater lakes, rivers, and swamps, as well as human-made habitats, such as oxidation ponds or even urban sewage systems. The African sharptooth catfish was introduced all over the world in the early 1980s for aquaculture purposes, so is found in countries far outside its natural habitat, such as Brazil, Vietnam, Indonesia, and India. Description The African sharptooth catfish is a large, eel-like fish, usually of dark gray or black coloration on the back, fading to a white belly. In Africa, this catfish has been reported as being second in size only to the vundu of the Zambesian waters, References External links Reproduction of African catfish [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
