Tilapia ( / t ɪ ˈ l ɑː p i ə / tih- LAH -pee-ə ) 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.
105-422: The Castanhão Dam ( Portuguese : Açude Castanhão ) is a dam in the state of Ceará , Brazil. It is the largest multiple use reservoir in the country, the largest on an intermittent river, and the main reservoir for the state and the metropolitan region of Fortaleza . The dam supplies drinking water, and supports industry, irrigation and fish farming. Through steady release of water the dam maintains water flow in
210-475: A skin graft material, for Müllerian agenesis , vaginal stenosis , and gender-affirming surgery . The skin-growing properties of tilapia skin are believed to be linked to its high type I collagen content and structural similarities to human skin. The material is also quite strong despite its low thickness. The current procedure for skin use calls for chemical sterilization with chlorhexidine, immersion in glycerol , followed by gamma ray sterilization, plus

Strains such as terapon (gunggong) and white goby ( biyang puti ) were abundant in Laguna de Bay . In 1988, WorldFish , Filipino and Norwegian researchers started aquaculture of the Genetically Improved Farmed Tilapia (GIFT). Other methods of tilapia population control are polyculture , with predators farmed alongside tilapia or hybridization with other species. Tilapia, introduced to

In the United States, tilapia skin has been used to successfully treat third-degree wounds to the paws of two black bears caught in California's Thomas wildfire , and also to treat burns on the paws of a black bear from California's Carr wildfire . Nile tilapia skin has completed a phase III clinical trial for superficial partial-thickness burns. The fish skin group showed faster healing, lower pain, reduced dressing changes, and lower treatment costs compared to silver sulfadiazine cream control. Nile tilapia skin has also been used in neovaginoplasty as
525-435: A consumption of 2.5 million. In modern aquaculture , wild-type Nile tilapia are not too often seen, as the dark color of their flesh is not much desired by many customers, and because it has a bit of a reputation of being a rough fish associated with poverty. However, they are fast-growing and give good fillets ; leucistic ("red") breeds which have lighter meat have been developed and are very popular. Hybrid stock
630-646: A few other genera, notably Oreochromis , and Sarotherodon . Even with this modification, apparently Tilapia was strongly poly– or paraphyletic . In 2013, a major taxonomic review resolved this by moving most former Tilapia spp. to several other genera. As a consequence, none of the species that are of major economic importance remain in Tilapia , but are instead placed in Coptodon , Oreochormis , and Sarotherodon . Tilapia have been used as biological controls for certain aquatic plant problems. They have

For the monogeneans , these especially include species of the megadiverse genus Cichlidogyrus , which are gill parasites. Species of Enterogyrus are parasites in the digestive system. Tilapia, as important aquaculture fishes, have been introduced widely all over the world, and often carried their monogenean parasites with them. In South China ,
840-651: A fish that carried a coin in its mouth . Though the passage does not name the fish, different tilapia species ( Sarotherodon galilaeus , Oreochromis aureus , Coptodon zillii , and Tristramella ) are found in the Sea of Galilee, where the author of the Gospel of Matthew recounts the event took place. These species have been the target of small-scale artisanal fisheries in the area for thousands of years. Tilapia typically have laterally compressed, deep bodies. Like other cichlids, their lower pharyngeal bones are fused into

Smaller West African species, such as Coelotilapia joka and species from the crater lakes of Cameroon , are more popular as aquarium fish. In specialised cichlid aquaria, tilapia can be mixed successfully with nonterritorial cichlids, armored catfish , tinfoil barbs , garpike , and other robust fish. Some species, including Heterotilapia buttikoferi , Coptodon rendalli , Pelmatolapia mariae , C. joka , and
1050-524: A form of Romance called Mozarabic which introduced a few hundred words from Arabic, Persian, Turkish, and Berber. Like other Neo-Latin and European languages, Portuguese has adopted a significant number of loanwords from Greek , mainly in technical and scientific terminology. These borrowings occurred via Latin, and later during the Middle Ages and the Renaissance. Portuguese evolved from

Their omega-6 fatty acid levels are unusually high. Multiple studies have evaluated the effects of adding flaxseed derivatives (a vegetable source of omega-3 fatty acids) to the feed of farmed tilapia. These studies have found both the more common omega-3 fatty acid found in

In many other countries, Portuguese is spoken by majorities as a second language. There remain communities of thousands of Portuguese (or Creole ) first language speakers in Goa , Sri Lanka , Kuala Lumpur , Daman and Diu , and other areas due to Portuguese colonization . In East Timor,

It is commonly fried or broiled as part of a dish. The common name "tilapia" is based on the name of the cichlid genus Tilapia , which is itself a latinization of either tlhapi , the Tswana word for "fish", or
1680-548: A preference for a floating aquatic plant, duckweed ( Lemna spp.), but also consume some filamentous algae. In Kenya , tilapia were introduced to control mosquitoes , which were causing malaria , because they consume mosquito larvae, consequently reducing the numbers of adult female mosquitoes, the vector of the disease. These benefits are, however, frequently outweighed by the negative aspects of tilapia as invasive species. Tilapia are unable to survive in temperate climates because they require warm water. The pure strain of

A complex set of muscles allows the upper and lower pharyngeal bones to be used as a second set of jaws for processing food (cf. morays ), allowing a division of labor between the "true jaws" ( mandibles ) and the " pharyngeal jaws ". This means they are efficient feeders that can capture and process a wide variety of food items. Their mouths are protrusible , usually bordered with wide and often swollen lips. The jaws have conical teeth. Typically, tilapia have

From 2012 to 2016 Ceará experienced the worst drought since 1910, with just 516 millimetres (20.3 in) of rain. At the end of 2012, the first year of low rainfall, the reservoir had 3,725,880 cubic metres (131,578,000 cu ft), or 55.61% of its capacity. By February 2016 the dam was releasing just 5 cubic metres (180 cu ft) per second, but water levels were dropping 1 centimetre (0.39 in) per day due to evaporation and consumption. By mid-2016, following low rainfall and high consumption,

Standard European Portuguese is also the preferred standard by the Portuguese-speaking African countries. As such, and despite the fact that its speakers are dispersed around the world, Portuguese has only two dialects used for learning: the European and the Brazilian. Some aspects and sounds found in many dialects of Brazil are exclusive to South America, and cannot be found in Europe. The same occur with

Most of these words derived from the Hispano-Celtic Gallaecian language of northwestern Iberia, and are very often shared with Galician since both languages have the same origin in the medieval language of Galician-Portuguese. A few of these words existed in Latin as loanwords from other Celtic sources, often Gaulish . Altogether these are over 3,000 words, verbs, toponymic names of towns, rivers, surnames, tools, lexicon linked to rural life and natural world. In

7455-496: The mid-16th century, Portuguese had become a lingua franca in Asia and Africa, used not only for colonial administration and trade but also for communication between local officials and Europeans of all nationalities. The Portuguese expanded across South America, across Africa to the Pacific Ocean, taking their language with them. Its spread was helped by mixed marriages between Portuguese and local people and by its association with Roman Catholic missionary efforts, which led to
7560-549: The minority Swiss Romansh language in many equivalent words such as maun ("hand"), bun ("good"), or chaun ("dog"). The Portuguese language is the only Romance language that preserves the clitic case mesoclisis : cf. dar-te-ei (I'll give thee), amar-te-ei (I'll love you), contactá-los-ei (I'll contact them). Like Galician , it also retains the Latin synthetic pluperfect tense: eu estivera (I had been), eu vivera (I had lived), vós vivêreis (you had lived). Romanian also has this tense, but uses
7665-1172: The most important languages when referring to loanwords. There are many examples such as: colchete / crochê ('bracket'/'crochet'), paletó ('jacket'), batom ('lipstick'), and filé / filete ('steak'/'slice'), rua ('street'), respectively, from French crochet , paletot , bâton , filet , rue ; and bife ('steak'), futebol , revólver , stock / estoque , folclore , from English "beef", "football", "revolver", "stock", "folklore." Examples from other European languages: macarrão ('pasta'), piloto ('pilot'), carroça ('carriage'), and barraca ('barrack'), from Italian maccherone , pilota , carrozza , and baracca ; melena ('hair lock'), fiambre ('wet-cured ham') (in Portugal, in contrast with presunto 'dry-cured ham' from Latin prae-exsuctus 'dehydrated') or ('canned ham') (in Brazil, in contrast with non-canned, wet-cured ( presunto cozido ) and dry-cured ( presunto cru )), or castelhano ('Castilian'), from Spanish melena ('mane'), fiambre and castellano. Portuguese belongs to
7770-462: The newspaper The Portugal News publishing data given from UNESCO, the highest potential for growth as an international language in southern Africa and South America . Portuguese is a globalized language spoken officially on five continents, and as a second language by millions worldwide.

In some parts of former Portuguese India , namely Goa and Daman and Diu , the language is still spoken by about 10,000 people. In 2014, an estimated 1,500 students were learning Portuguese in Goa. Approximately 2% of
7980-417: The number of Portuguese speakers is quickly increasing as Portuguese and Brazilian teachers are making great strides in teaching Portuguese in the schools all over the island. Additionally, there are many large Portuguese-speaking immigrant communities all over the world. According to estimates by UNESCO , Portuguese is the fastest-growing European language after English and the language has, according to

Other countries where Portuguese is commonly taught in schools or where it has been introduced as an option include Venezuela , Zambia ,
8190-464: The peninsula and over the next 300 years totally integrated into the local populations. Some Germanic words from that period are part of the Portuguese lexicon, together with place names, surnames, and first names. With the Umayyad conquest beginning in 711, Arabic became the administrative and common language in the conquered regions, but most of the remaining Christian population continued to speak

The Community of Portuguese Language Countries (in Portuguese Comunidade dos Países de Língua Portuguesa , with
8400-463: The population of urban Angola speaks Portuguese natively, with approximately 85% fluent; these rates are lower in the countryside. Just over 50% (and rapidly increasing) of the population of Mozambique are native speakers of Portuguese, and 70% are fluent, according to the 2007 census. Portuguese is also spoken natively by 30% of the population in Guinea-Bissau, and a Portuguese-based creole
8505-541: The preferred "aquatic chickens" of the trade. Because of their large size, rapid growth, and palatability, tilapia cichlids are the focus of major farming efforts, specifically various species of Oreochromis , Sarotherodon , and Coptodon (all were formerly in the namesake genus Tilapia ). Like other large fish, they are a good source of protein and popular among artisanal and commercial fisheries . Most such fisheries were originally found in Africa, but outdoor fish farms in tropical countries, such as Papua New Guinea ,
8610-433: The productive output of both. Arkansas stocks many public ponds and lakes to help with vegetation control, favoring tilapia as a robust forage species and for anglers. In Kenya, tilapia help control mosquitoes , which carry malaria parasites. They consume mosquito larvae , which reduces the numbers of adult females, the disease's vector . In Brazil , Nile tilapia ( Oreochromis niloticus ) fish skin applied as
8715-672: The question of desirability of Tilapia culture in other parts of India. Whole tilapia fish can be processed into skinless, boneless fillets. In some of the commercial strains, the yield has been reported up to 47% at harvest weight. Tilapia are among the commercially important aquaculture species that are susceptible to off-flavors (others include trout, barramundi , and channel catfish ). These 'muddy' or 'musty' flavors are normally caused by geosmin and 2-methylisoborneol , organic products of ubiquitous cyanobacteria that are often present or bloom sporadically in water bodies and soil. These flavors are no indication of freshness or safety of
8820-679: The reservoir filled in 2004. As of 14 January 2017 the rains from the start of the rainy season had not yet started to replenish the reservoir, which was at 4.99% of total capacity. As of 22 February 2018 the reservoir was at 2,08 %. Rain returned in Ceará in February 2018 and on 13 May Castanhão has reached 8,68 % of its capacity. But on 4 October it was down again - 6,06 % only. [REDACTED] Media related to Açude Castanhão at Wikimedia Commons Portuguese language Portuguese ( endonym : português or língua portuguesa )
8925-403: The reservoir was down to just over 550,000 cubic metres (19,000,000 cu ft). Fish farmers said they could only continue farming tilapia until the end of the year. The low water levels in 2014 revealed a crack in the structure of one of the floodgates. As of mid-2016 nothing had been done to repair it. By December 2016 the reservoir had fallen to 5.17% of capacity, the lowest level since
9030-546: The result of expansion during colonial times, a cultural presence of Portuguese speakers is also found around the world. Portuguese is part of the Ibero-Romance group that evolved from several dialects of Vulgar Latin in the medieval Kingdom of Galicia and the County of Portugal , and has kept some Celtic phonology. With approximately 236 million native speakers and 27 million second language speakers, Portuguese has approximately 263.8 million total speakers. It

The reservoir has 6,700,000,000 cubic metres (2.4 × 10 cu ft) capacity, of which 250,000,000 cubic metres (8.8 × 10 cu ft) is dead volume. The reservoir covers 325 square kilometres (125 sq mi), and extends for 58 kilometres (36 mi) from southwest to northeast along
9240-679: The state in the 1950s as a cheap protein source, quickly spread across the state’s freshwater bodies because of its ability to thrive in polluted, low-oxygen environments. The Fisheries Research Committee has recommended the culture of this fish only in areas in the western slopes of the Western Ghats and the coastal strip between Cape Comorin and south of and excluding river Tapti, and in districts of Tinnevellv, Madurai and Ramnad in Madras south of and including river Vaigai. The Committee has suggested further investigation to enable it to examine
9345-522: The state, but it has just over half the capacity of the Castanhão. The idea of building the Castanhão Dam came from the Cunha family, who led the region's oligarchy at the time. They owned the Castanhão farm, which is now almost completely submerged by the reservoir. The Castanhão Dam was one of the most important projects of DNOCS (National Department of Drought Works). Work was started in 1995 under
9450-695: The three main types of fish caught in Talmudic times from the Sea of Galilee , specifically the Galilean comb ( Sarotherodon galilaeus ). Today, in Modern Hebrew, the fish species is called amnoon (probably a compound of am , "mother" and noon , "fish"). In English, it is sometimes known by the name "St. Peter's fish", which comes from the narrative in the Gospel of Matthew about the apostle Peter catching
9555-450: The use of so-called "supermales" that have homozygous male sex chromosomes (resulting in all their offspring receiving a male sex chromosome and thus becoming males). Males are preferred because they grow much faster than females. Additionally, because tilapia are prolific breeders, the presence of female tilapia results in rapidly increasing populations of small fish, rather than a stable population of harvest-size animals. Tilapia, as
9660-439: The use of toxic chemicals and heavy metal-based algaecides. However, their environmental impact as an invasive species may outweigh their ecological benefit. Their tolerance for a wide range of environmental conditions allow them to thrive in polluted or otherwise degraded aquatic habitats. They are used for zoo ponds as a source of food for birds. Tilapia can be farmed with shrimp in a symbiotic manner, positively enhancing
9765-509: The water follows the Canal do Trabalhador to the state capital. The Jaguaribe River used to be called the largest seasonal river in the world. The river basin cover about 75,669 square kilometres (29,216 sq mi), over half the area of the state. The 633 kilometres (393 mi) river is the largest in Ceará. Before the dam was built the Orós Dam on the Jaguaribe River was the largest in

Unlike carnivorous fish, tilapia can feed on algae or any plant-based food. This reduces the cost of tilapia farming, reduces fishing pressure on prey species, avoids concentrating toxins that accumulate at higher levels of the food chain , and makes tilapia
10185-520: Was also said to accompany and protect the sun god on his daily journey across the sky, and a tilapia painted on tomb walls may recall part of spell 15 of the Book of the Dead by which the deceased hopes to take his place in the sun boat: "You see the tilapia in its [true] form at the turquoise pool", and "I behold the tilapia in its [true] nature guiding the speedy boat in its waters." Tilapia were one of

10395-470: Was controversial, forcing relocation of thousands of people and relocation of the municipal seat of Jaguaribara . The Castanhão Ecological Station was created in compensation for the environmental impact. The municipal seat of Jaguaribara and large areas of the municipality were covered by the reservoir. A new seat, Nova Jaguaribara, was built, but as of 2016 there were still outstanding claims for indemnification of lost land. The giant dam supplies water to
10500-537: Was marked by the publication of the Cancioneiro Geral by Garcia de Resende , in 1516. The early times of Modern Portuguese, which spans the period from the 16th century to the present day, were characterized by an increase in the number of learned words borrowed from Classical Latin and Classical Greek because of the Renaissance (learned words borrowed from Latin also came from Renaissance Latin ,
10605-403: Was merely brackish now live in salt concentrations so high that other marine fish cannot survive. Tilapia are also known to be mouth-brooding species, which means they carry the fertilized eggs and young fish in their mouths for several days after the yolk sac is absorbed. Historically, all tilapia have been included in their namesake genus Tilapia . In recent decades, some were moved into
10710-676: Was reported that an angler caught a Tilapia on a crankbait at the Jones Point Park under the Woodrow Wilson Bridge , which is on the Potomac River . Many state fish and wildlife agencies in the United States, Australia, South Africa, and elsewhere consider them to be invasive species . Larger tilapia species are generally poor community aquarium fish because they eat plants, dig up the bottom, and fight with other fish. The larger species are often raised as
10815-554: Was the language of the poetry of the troubadours in France. The Occitan digraphs lh and nh , used in its classical orthography, were adopted by the orthography of Portuguese , presumably by Gerald of Braga , a monk from Moissac , who became bishop of Braga in Portugal in 1047, playing a major role in modernizing written Portuguese using classical Occitan norms. Portugal became an independent kingdom in 1139, under King Afonso I of Portugal . In 1290, King Denis of Portugal created

Lat. salire ("to exit"), tenere ("to have"), catena ("jail"), Port. sair , ter , cadeia . When the elided consonant was n , it often nasalized the preceding vowel: cf. Lat. manum ("hand"), ranam ("frog"), bonum ("good"), Old Portuguese mão , rãa , bõo (Portuguese: mão , rã , bom ). This process
11025-462: Was the source of most of the language's distinctive nasal diphthongs. In particular, the Latin endings -anem , -anum and -onem became -ão in most cases, cf. Lat. canis ("dog"), germanus ("brother"), ratio ("reason") with Modern Port. cão , irmão , razão , and their plurals -anes , -anos , -ones normally became -ães , -ãos , -ões , cf. cães , irmãos , razões .
