Oreochromis
''Oreochromis'' is a large genus of Oreochromini, oreochromine cichlids, fishes Endemism, endemic to Africa and the Middle East. A few species from this genus have been Introduced species, introduced far outside their native range and are important in Aquaculture of tilapia, aquaculture. Many others have very small ranges; some are seriously Threatened species, threatened, and ''O. ismailiaensis'' and ''O. lidole'' possibly are extinct. Although ''Oreochromis'' primarily are freshwater fish of rivers, lakes and similar habitats, several species can also thrive in brackish waters and some even survive in hypersaline conditions with a salinity that far surpasses that of seawater. In addition to overfishing and habitat loss, some of the more localized species are threatened by the introduction of other, more widespread ''Oreochromis'' species into their ranges. This is because they—in addition to competing for the local resources—often are able to Hybrid (biology), hybridize. '' ... [...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 ...

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 aquariu ...

Aquaculture Of Tilapia
Tilapia has become the third most important fish in aquaculture after carp and salmon; worldwide production exceeded in 2002 and increases annually. Because of their high protein content, large size, rapid growth (6 to 7 months to grow to harvest size), and palatability, a number of coptodonine and oreochromine cichlids—specifically, various species of ''Coptodon'', ''Oreochromis'', and ''Sarotherodon''—are the focus of major aquaculture efforts. Tilapia fisheries originated in Africa and the Levant. The accidental and deliberate introductions of tilapia into South and Southeast Asian freshwater lakes have inspired outdoor aquaculture projects in various countries with tropical climates, including Honduras, Papua New Guinea, the Philippines, and Indonesia. Tilapia farm projects in these countries have the highest potential to be "green" or environmentally friendly. In temperate zone localities, tilapia farmers typically need a costly energy source to maintain a tropical tem ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Oreochromis Hunteri
The Lake Chala tilapia (''Oreochromis hunteri'') is a species of cichlid fish that is endemic to Lake Chala, a small crater lake on the border of Kenya and Rombo District of Kilimanjaro Region in Tanzania. It mostly lives in relatively deep water, at depths between . It is considered critically endangered by the IUCN, with the two primary threats being deterioration of its habitat due to siltation, and other non-native tilapia species that have been introduced to Lake Chala. Before these introductions, the Lake Chala tilapia was the only fish in Lake Chala. It is very closely related to the similar Jipe tilapia (''O. jipe''), another highly threatened species from the same general region of Kenya and Tanzania. The Lake Chala tilapia can reach a standard length of up to . The specific name ''hunteri'' honours the British zoologist Henry C. V. Hunter (1861-1934), who collected the type, and who provided notes on this species' distribution. ''O. hunteri'' is the type species o ...

Alcolapia
''Alcolapia'' is a genus of small fishes in the family Cichlidae. Their native range is restricted to margins of Lake Natron and Lake Magadi, as well as similar conditions in nearby hot springs, in Kenya and Tanzania. They live in waters that are warm (mostly , although occasionally down to ), hypersaline (salinity above 40‰) and alkaline ( pH above 10). Species from this genus have also been introduced to Lake Nakuru and Lake Elmenteita. They are the only fish in their range. The different ''Alcolapia'' species differ primarily in the position of their mouth (straight, upturned or downturned) and the colors of the adult males. They are fairly small fish, with the largest species reaching up to in standard length. They mostly feed on algae and cyanobacteria, but also take other plant material, fish eggs, fry and remains, and insects in smaller quantities (except ''A. alcalica'', which feed on other plant material at about the same level as algae and cyanobacteria). They are ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Oreochromini
Oreochromini is a tribe of cichlids in the Pseudocrenilabrinae subfamily that is native to Africa and Western Asia, but a few species have been widely introduced to other parts of the world. It was formerly considered to be part of the tribe Tilapini but more recent workers have found that the Tilapini ''sensu lato'' is paraphyletic. Despite this change, species in Oreochromini are still referred to by the common name tilapia and some of the most important tilapia in aquaculture —certain species of ''Oreochromis'' and ''Sarotherodon''— are part of this tribe. In contrast, several species have small ranges and are seriously threatened; a few are already extinct ('' Tristramella sacra'') or possibly extinct (''Oreochromis ismailiaensis'' and '' O. lidole''). Cichlids in the tribe ''Oreochromini'' are mouthbrooders, carrying the eggs and fry in their mouths instead of placing them in a nest. The numerous ''Oreochromis'' species are maternal mouthbrooders, meaning only the femal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Tilapiine Cichlid
The Tilapiini (occasionally Tilapini) are a tribe within the family Cichlidae commonly known as tilapiine cichlids. Formerly this tribe contained many other genera and species, including the economically important ''Oreochromis'' and ''Sarotherodon'', but a taxonomic review found that this grouping was paraphyletic and most were moved to Coelotilapini, Coptodonini, Heterotilapini, Oreochromini and Pelmatolapiini. Together, most species in these tribes are called "tilapias". In a more distant past, a number of other, more different genera like ''Steatocranus'' also were included in Tilapiini. With these as separate, Tilapiini now is a much more restricted tribe with only three genera and about half a dozen species from Central and Southern Africa. Systematics The tilapiines were recognised by the ichthyologist Ethylwynn Trewavas mtDNA-based phylogenies of tilapiines must be evaluated with caution, however, as they are usually close to, but do not represent the true evolutionar ...

Tilapia (genus)
''Tilapia'' is a genus of cichlid fishes endemic to freshwater habitats in Southern Africa. In the past this was a very large genus including all species with the common name tilapia, but today the vast majority are placed in other genera.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. Species and taxonomy In the past, ''Oreochromis'' and ''Sarotherodon'' were retained in the genus ''Tilapia'', but these are treated as separate genera by all recent authorities.Nagl, S.; Tichy, H.; Mayer, W.E.; Samonte, I.E.; McAndrew, B.J., and Klein, J. (2001). ''Classification and Phylogenetic Relationships of African Tilapiine Fishes Inferred from Mitochondrial DNA Sequences.'' Molecular Phylogenetics and Evolution 20(3): 361–374.

Middle East
The Middle East ( ar, الشرق الأوسط, ISO 233: ) is a geopolitical region commonly encompassing Arabian Peninsula, Arabia (including the Arabian Peninsula and Bahrain), Anatolia, Asia Minor (Asian part of Turkey except Hatay Province), East Thrace (European part of Turkey), Egypt, Iran, the Levant (including Syria (region), Ash-Shām and Cyprus), Mesopotamia (modern-day Iraq), and the Socotra Governorate, Socotra Archipelago (a part of Yemen). The term came into widespread usage as a replacement of the term Near East (as opposed to the Far East) beginning in the early 20th century. The term "Middle East" has led to some confusion over its changing definitions, and has been viewed by some to be discriminatory or too Eurocentrism, Eurocentric. The region includes the vast majority of the territories included in the closely associated definition of Western Asia (including Iran), but without the South Caucasus, and additionally includes all of Egypt (not just the Sina ...

MtDNA
Mitochondrial DNA (mtDNA or mDNA) is the DNA located in mitochondria, cellular organelles within eukaryotic cells that convert chemical energy from food into a form that cells can use, such as adenosine triphosphate (ATP). Mitochondrial DNA is only a small portion of the DNA in a eukaryotic cell; most of the DNA can be found in the cell nucleus and, in plants and algae, also in plastids such as chloroplasts. Human mitochondrial DNA was the first significant part of the human genome to be sequenced. This sequencing revealed that the human mtDNA includes 16,569 base pairs and encodes 13 proteins. Since animal mtDNA evolves faster than nuclear genetic markers, it represents a mainstay of phylogenetics and evolutionary biology. It also permits an examination of the relatedness of populations, and so has become important in anthropology and biogeography. Origin Nuclear and mitochondrial DNA are thought to be of separate evolutionary origin, with the mtDNA being derived from t ...

Catalog Of Fishes
Catalog of Fishes is a comprehensive on-line database and reference work on the scientific names of fish species and genera. It is global in its scope and is hosted by the California Academy of Sciences. It has been compiled and is continuously updated by the curator emeritus of the CAS fish collection, William N. Eschmeyer. The taxonomy maintained by the Catalog of Fishes is considered authoritative and it is used as a baseline reference for instance by the broader global fish database FishBase, which involves cross-references to the Catalog's information for all accepted taxa. , the searchable catalogue contains entries for about 58,300 fish species names, about 33,400 of which are currently accepted (valid), and for some 10,600 genera (5,100 valid).
