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 ...

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 te ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Oreochromis Niloticus
The Nile tilapia (''Oreochromis niloticus'') is a species of tilapia, a cichlid fish native to the northern half of Africa and the Levante area, including Israel, and Lebanon. Numerous introduced populations exist outside its natural range. It is also commercially known as mango fish, nilotica, or boulti. The first name leads to easy confusion with another tilapia which is traded commercially, the mango tilapia (''Sarotherodon galilaeus''). Description The Nile tilapia reaches up to in length, and can exceed . As typical of tilapia, males reach a larger size and grow faster than females. Wild, natural-type Nile tilapias are brownish or grayish overall, often with indistinct banding on their body, and the tail is vertically striped. When breeding, males become reddish, especially on their fins. Although commonly confused with the blue tilapia (''O. aureus''), that species lacks the striped tail pattern, has a red edge to the dorsal fin (this edge is gray or black in Nile til ...

Mango Tilapia
The mango tilapia (''Sarotherodon galilaeus'') is a species of fish from the cichlid family that is native to fresh and brackish waters in Africa and the Levant. Other common names include Galilaea tilapia, Galilean comb, Galilee St. Peter's fish, and St. Peter's fish. (To differentiate from other Israeli species of "St. Peter's fish" see below). This is a relatively large cichlid at up to in total length and about in weight. It is very important to local fisheries and the species is also aquacultured. In addition to the nominate subspecies, four subspecies were recognized in the past, but today the species is considered monotypic. It is a bi-parental mouthbrooder. The mating strategies can vary. Both uni-parent and bi-parent mouthbrooding is used, and monogamous or polygamous behaviour. Distribution and habitat This widespread species is found in lakes, rivers and other fresh or brackish habitats in northern and central Africa (including Saharan oases), ranging as far sout ...

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 ...

Coptodon
''Coptodon'' is a genus of cichlids native to fresh, brackish and coastal marine waters in Africa with ''C. zillii'' also found in the Middle East. It is the only genus in the tribe Coptodonini. Formerly included in '' Tilapia'', this genus and tribe was separated in 2013.Dunz, A.R. & Schliewen, U.K. (2013): Molecular phylogeny and revised classification of the haplotilapiine cichlid fishes formerly referred to as ''“Tilapia”''. ''Molecular Phylogenetics and Evolution, Available online 29 March 2013 doi: 10.1016/j.ympev.2013.03.015'' Despite the change in genus, ''Coptodon'' spp. are still referred to by the common name tilapia. Several species are important in local fisheries and a few are aquacultured. Appearance Depending on the exact species, the maximum length of ''Coptodon'' ranges from ; the smallest is ''C. snyderae'', which also is the smallest tilapia. Although the individual species typically have different nonbreeding and breeding colors, the sexes are alike. So ... [...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 evolut ...

Coelotilapia Joka
''Coelotilapia joka'' is a vulnerable species of cichlid fish from rivers in Sierra Leone and Liberia in West Africa. This relatively small tilapia formerly was included in the genus ''Tilapia'', but in 2013 it was moved to its own genus ''Coelotilapia'' and tribe Coelotilapini. It is an oval shaped fish with a black body coloring. Eight to nine yellow, transverse stripes mark the body. The head has small, irregular yellow lines that extend from the eye to the snout, forehead, and mouth. It is one of the few tilapia species that regularly are kept in aquariums. Characteristics ''Coelotilapia joka'' can reach up to about in total length. It originates from West Africa; found near the banks of clear rivers and tributaries of the lower parts of the Moa and Moro Rivers, southern Sierra Leone and northern Liberia Liberia (), officially the Republic of Liberia, is a country on the West African coast.

Aquaponics
Aquaponics is a food production system that couples aquaculture (raising aquatic animals such as fish, crayfish, snails or prawns in tanks) with hydroponics (cultivating plants in water) whereby the nutrient-rich aquaculture water is fed to hydroponically grown plants. As existing hydroponic and aquaculture farming techniques form the basis of all aquaponic systems, the size, complexity, and types of foods grown in an aquaponic system can vary as much as any system found in either distinct farming discipline. History Aquaponics has ancient roots, although there is some debate on its first occurrence: *Aztec cultivated agricultural islands known as ''chinampas'' in a system considered by some to be an early form of aquaponics for agricultural use, where plants were raised on stationary (or sometime movable) islands in lake shallows and waste materials dredged from the Chinampa canals and surrounding cities were used to manually irrigate the plants. *South China and the whole ...

Heterotilapia
''Heterotilapia'' is a genus of cichlid fish that are native to rivers from Guinea-Bissau to Liberia in tropical West Africa. Formerly considered a subgenus of ''Tilapia'', in 2013, it was elevated to genus rank. They are medium-large cichlids, up to about in standard length depending on the species, and with a distinctive dark-and-light banded pattern. They are substrate spawners and brooders (not mouthbrooders as some other tilapias). ''H. buttikoferi'' is a common species that also has been introduced outside its native range, but ''H. cessiana'' is highly localized and critically endangered. Species Two recognized species are in this genus: * ''Heterotilapia buttikoferi'' ( Hubrecht, 1881) (zebra tilapia) * ''Heterotilapia cessiana ''Heterotilapia'' is a genus of cichlid fish that are native to rivers from Guinea-Bissau to Liberia in tropical West Africa.
