Tilapia Busumana
''Tilapia busumana'' is a species of cichlid native to Lake Bosumtwi, the Bia River Basin, the Pra River Basin and the Tano River Basin in Ghana and Côte d'Ivoire. This species can reach a length of SL. It can also be found in the aquarium trade. In 2013, research published by Dunz & Schliewen indicated that this species does not belong in the genus ''Tilapia'', but is rather closer to '' "Steatocranus" irvinei'' (itself not related to the remaining ''Steatocranus'') and ''Gobiocichla ''Gobiocichla'' is a small genus of rheophilic cichlids native to the Cross River (Nigeria), Cross (Manyu River, Manyu) and Niger Rivers in Africa. Species There are currently two recognized species in this genus: * ''Gobiocichla ethelwynnae'' T ...''. It is currently retained in ''Tilapia'' pending further research.Dunz, A.R., and Schliewen, U.K. (2013).

Albert Günther
Albert Karl Ludwig Gotthilf Günther Fellow of the Royal Society, FRS, also Albert Charles Lewis Gotthilf Günther (3 October 1830 – 1 February 1914), was a German-born British zoologist, ichthyologist, and herpetologist. Günther is ranked the second-most productive reptile taxonomist (after George Albert Boulenger) with more than 340 reptile species described. Early life and career Günther was born in Esslingen am Neckar, Esslingen in Swabia (Württemberg). His father was a ''Stiftungs-Commissar'' in Esslingen and his mother was Eleonora Nagel. He initially schooled at the Stuttgart Gymnasium. His family wished him to train for the ministry of the Lutheran Church for which he moved to the University of Tübingen. A brother shifted from theology to medicine, and he, too, turned to science and medicine at Tübingen in 1852. His first work was "''Ueber den Puppenzustand eines Distoma''". He graduated in medicine with an M.D. from Tübingen in 1858, the same year in which he pub ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cichlid
Cichlids are fish from the family Cichlidae in the order Cichliformes. Cichlids were traditionally classed in a suborder, the Labroidei, along with the wrasses ( Labridae), in the order Perciformes, but molecular studies have contradicted this grouping. The closest living relative of cichlids is probably the convict blenny, and both families are classified in the 5th edition of ''Fishes of the World'' as the two families in the Cichliformes, part of the subseries Ovalentaria. This family is both large and diverse. At least 1,650 species have been scientifically described, making it one of the largest vertebrate families. New species are discovered annually, and many species remain undescribed. The actual number of species is therefore unknown, with estimates varying between 2,000 and 3,000. Many cichlids, particularly tilapia, are important food fishes, while others, such as the '' Cichla'' species, are valued game fish. The family also includes many popular freshwater ...

Lake Bosumtwi
Lake Bosumtwi is the only natural lake in Ghana. It is situated within an ancient impact crater that is about in diameter. It is about south-east of Kumasi, the capital of Ashanti, and is a popular recreational area. There are about 30 villages near the crater lake of Lake Bosumtwi, with a combined population of about 70,000. The most popular amongst the villages where tourists usually settle is Abono. The Ashanti consider Bosumtwi a sacred lake. According to traditional belief, the souls of the dead come here to bid farewell to the goddess Asase Ya. Because of this, it is considered permissible to fish in the lake only from wooden planks. Among the fish species in the lake is the endemic cichlid '' Hemichromis frempongi'', and the near-endemic cichlids '' Tilapia busumana'' and '' T. discolor''. Impact crater The Lake Bosumtwi impact crater is in diameter, slightly larger than the present lake which is approximately across, and is estimated to be 1.07 million years ...

Pra River (Ghana)
The Pra River is a river in Ghana, the easternmost and the largest of the three principal rivers that drain the area south of the Volta divide. Rising in the Kwahu Plateau near Mpraeso and flowing southward for 240 km through rich cocoa and farming areas and valuable forests in the Akan lowlands, the Pra enters the Gulf of Guinea east of Takoradi. In the 19th century, the Pra served as the border between the Ashanti Confederacy and the Gold Coast. The Pra has many cataracts, notably the Bosomasi Rapids at Anyinabrim, and for most of its length is not navigable even by canoe. However, in the early part of the twentieth century the Pra was used extensively to float timber to the coast for export. This trade is now carried by road and rail transportation. The main tributaries are the Ofin, Anum and Birim rivers. The northern part of the Pra is still worked for artisan gold with metallic mercury, which has caused some contamination. The Birim river valley is a major source ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Fish Measurement
Fish measurement is the measuring of individual fish and various parts of their anatomies. These data are used in many areas of ichthyology, including taxonomy and fisheries biology. Overall length * Standard length (SL) is the length of a fish measured from the tip of the snout to the posterior end of the last vertebra or to the posterior end of the midlateral portion of the hypural plate. Simply put, this measurement excludes the length of the caudal (tail) fin. * Total length (TL) is the length of a fish measured from the tip of the snout to the tip of the longer lobe of the caudal fin, usually measured with the lobes compressed along the midline. It is a straight-line measure, not measured over the curve of the body. Standard length measurements are used with Teleostei (most bony fish), while total length measurements are used with Myxini ( hagfish), Petromyzontiformes ( lampreys), and (usually) Elasmobranchii (shark Sharks are a group of elasmobranch fish chara ...

Aquarium
An aquarium (plural: ''aquariums'' or ''aquaria'') is a vivarium of any size having at least one transparent side in which aquatic plants or animals are kept and displayed. Fishkeepers use aquaria to keep fish, invertebrates, amphibians, aquatic reptiles, such as turtles, and aquatic plants. The term ''aquarium'', coined by English naturalist Philip Henry Gosse, combines the Latin root , meaning 'water', with the suffix , meaning 'a place for relating to'. The aquarium principle was fully developed in 1850 by the chemist Robert Warington, who explained that plants added to water in a container would give off enough oxygen to support animals, so long as the numbers of animals did not grow too large. The aquarium craze was launched in early Victorian England by Gosse, who created and stocked the first public aquarium at the London Zoo in 1853, and published the first manual, ''The Aquarium: An Unveiling of the Wonders of the Deep Sea'' in 1854.Katherine C.

Steatocranus Irvinei
''Steatocranus'' is a genus of small rheophilic cichlids mostly native to the Congo River Basin in DR Congo/Congo Brazzaville, although one species, '' S. irvinei'', is restricted to the Volta River in Ghana and Burkino Faso, and it belongs in a separate genus.Dunz, A.R., and Schliewen, U.K. (2013). Molecular phylogeny and revised classification of the haplotilapiine cichlid fishes formerly referred to as “Tilapia”. Molecular Phylogenetics and Evolution, online 29 March 2013. doi:10.1016/j.ympev.2013.03.015 There are also at least 10 undescribed species in the Congo River basin awaiting scientific description. The fish in this genus all have relatively reduced swim bladder function. The name ''Steatocranus'' refers to the fatty deposit on the forehead of most species. Two species, '' S. casuarius'' (also known as the lionhead or buffalohead cichlid) and '' S. tinanti'' are relatively common in the aquarium trade.
