Gumara River
Gumara River is a river of northern-western Ethiopia. It empties into Lake Tana at from the east. Hot springs on the Gumara's banks at Wanzaye, which were popular in medicinal hot baths from the late 18th century till now, were already mentioned by missionary Henry Stern. The river is an important spawning ground for native fish species, which include barbus, tilapia and 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, ....Gordon A, Sewmehon Demissie Tegegne and Melaku Tadesse"Marketing systems for fish from Lake Tana, Ethiopia: Opportunities for improved marketing and livelihoods."

Ethiopia
Ethiopia, , om, Itiyoophiyaa, so, Itoobiya, ti, ኢትዮጵያ, Ítiyop'iya, aa, Itiyoppiya officially the Federal Democratic Republic of Ethiopia, is a landlocked country in the Horn of Africa. It shares borders with Eritrea to the north, Djibouti to the northeast, Somalia to the east and northeast, Kenya to the south, South Sudan to the west, and Sudan to the northwest. Ethiopia has a total area of . As of 2022, it is home to around 113.5 million inhabitants, making it the 13th-most populous country in the world and the 2nd-most populous in Africa after Nigeria. The national capital and largest city, Addis Ababa, lies several kilometres west of the East African Rift that splits the country into the African and Somali tectonic plates. Anatomically modern humans emerged from modern-day Ethiopia and set out to the Near East and elsewhere in the Middle Paleolithic period. Southwestern Ethiopia has been proposed as a possible homeland of the Afroasiatic langua ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lake Tana
Lake Tana ( am, ጣና ሐይቅ, T’ana ḥāyik’i; previously Tsana) is the largest lake in Ethiopia and the source of the Blue Nile. Located in Amhara Region in the north-western Ethiopian Highlands, the lake is approximately long and wide, with a maximum depth of , and an elevation of . Lake Tana is fed by the Gilgel Abay, Reb and Gumara rivers. Its surface area ranges from , 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 (Tis Abbai) and hydro-power station. In 2015, the Lake Tana region was nominated as a UNESCO Biosphere Reserve recognizing its national and international natural and cultural importance. Overview Lake Tana was formed by volcanic activity, blocking the course of inflowing rivers in the early Pleistocene epoch, about 5 million years ago. The lake was originally much larger than it is today. S ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Henry Aaron Stern
Henry Aaron Stern (Unterreichenbach, near Gelnhausen, 11 April 1820 – Hackney, 13 May 1885) was an Anglican missionary and captive in Abyssinia. He was the youngest son of Aaron Stern, a Jew, and his wife Hannah, was born in the Duchy of Hessen-Kassel. His parents moved to Frankfurt during his childhood, and he went to school there. His father destined him for the medical profession but, at his son's special request, sent him to Hamburg when he was seventeen years old to be trained as a merchant. In 1839 Stern was offered a good appointment in London, but the firm failed, and he found himself unsuccessful in obtaining employment. While in London he was taken to the Palestine Place chapel, where, through the influence of Dr. McCaul, he converted to Christianity and was baptised on 15 March 1840. He was then placed in the Operative Jewish Converts' Institution, where he learned the trade of a printer. In August 1842 he was admitted into the Hebrew College of the London Jews' Soc ...

Richard Pankhurst (academic)
Richard Keir Pethick Pankhurst OBE (3 December 1927 – 16 February 2017) was a British-Ethiopian scholar, founding member of the Institute of Ethiopian Studies, and former professor at the University of Addis Ababa in Ethiopia. His books have been reviewed in scholarly journals, with Edward Ullendorff calling his ''The Ethiopians'' as another testimony to his "remarkable diligence and industry in the service of Ethiopian studies". He is known for his research on economic history and socio-cultural studies on Ethiopia. Early life and education Pankhurst was born in 1927 in Woodford Green to left communist and former suffragette Sylvia Pankhurst and Italian anarchist Silvio Corio. His maternal grandparents were Emmeline and Richard Pankhurst. Pankhurst studied at Bancroft's School in Woodford, then at the London School of Economics, [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Barbus
''Barbus'' is a genus of ray-finned fish in the family Cyprinidae. The type species of ''Barbus'' is the common barbel, first described as ''Cyprinus barbus'' and now named ''Barbus barbus''. ''Barbus'' is the namesake genus of the subfamily Barbinae, but given their relationships, that taxon is better included in the Cyprininae at least for the largest part (including the type species of ''Barbus''). Description and uses Their common names – barbs and barbels – refer to the fact that most members of the genera have a pair of barbels on their mouths, which they can use to search for food at the bottom of the water. Barbels are often fished for food; in some locations they are of commercial significance. The roe of barbels is poisonous, however. The large ''Barbus'' barbs are also often eaten in their native range. At Shanhûr in Egypt, remains of a jar from the sixth- to seventh-century AD were unearthed that contained fish bones. The fish were apparently pick ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

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] |
Tributaries Of Lake Tana
A tributary, or affluent, is a stream or river that flows into a larger stream or main stem (or parent) river or a lake. A tributary does not flow directly into a sea or ocean. Tributaries and the main stem river drain the surrounding drainage basin of its surface water and groundwater, leading the water out into an ocean. The Irtysh is a chief tributary of the Ob river and is also the longest tributary river in the world with a length of . The Madeira River is the largest tributary river by volume in the world with an average discharge of . A confluence, where two or more bodies of water meet, usually refers to the joining of tributaries. The opposite to a tributary is a distributary, a river or stream that branches off from and flows away from the main stream. PhysicalGeography.net, Michael Pidwirny & ...
