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

315-754: A "traditional" dish, was first introduced in the Philippines in 1950 with Mozambique tilapia followed by Nile tilapia in 1972 from Thailand. 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

420-800: A bandage is first used in a 2017 clinical trial to treat burn injuries, after successful trial in rats. 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

735-457: A few washes with saline in between. As with most fish, tilapia harbor a variety of parasites . 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

945-539: A food source, though, because they grow rapidly and tolerate high stocking densities and poor water quality. 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

1155-625: A large part of the diaspora is a part of the already-counted population of the Portuguese-speaking countries and territories, such as the high number of Brazilian and PALOP emigrant citizens in Portugal or the high number of Portuguese emigrant citizens in the PALOP and Brazil. The Portuguese language therefore serves more than 250 million people daily, who have direct or indirect legal, juridical and social contact with it, varying from

1260-434: A less nutritious fish than generally believed. The fish's omega-3 fatty acid content is often far lower than that of other commonly eaten fish species. 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

1365-459: A long dorsal fin, and a lateral line that often breaks towards the end of the dorsal fin, and starts again two or three rows of scales below. Some Nile tilapia can grow as long as 60 centimetres (2 ft). Other than their temperature sensitivity, tilapia exist in or can adapt to a very wide range of conditions. An extreme example is the Salton Sea , where tilapia introduced when the water

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,

1575-529: A popular and affordable food in the Philippines with a mild taste, tilapia has been the fourth-most consumed fish in the United States since 2002, favored for its low cost and easy preparation. 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

1785-503: A single tooth-bearing structure. 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

It is the official language of Angola , Brazil , Cape Verde , Guinea-Bissau , Mozambique , Portugal and São Tomé and Príncipe , and has co-official language status in East Timor , Equatorial Guinea and Macau . Portuguese-speaking people or nations are known as Lusophone ( lusófono ). As

2100-607: Is a tourist attraction. With its submerged city, it is of great interest to divers. 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,

Between AD 409 and AD 711, as the Roman Empire collapsed in Western Europe , the Iberian Peninsula was conquered by Germanic peoples of the Migration Period . The occupiers, mainly Suebi , Visigoths and Buri who originally spoke Germanic languages , quickly adopted late Roman culture and the Vulgar Latin dialects of

2415-561: Is also used in aquaculture; Nile × blue tilapia hybrids are usually rather dark, but a light-colored hybrid breed known as "Rocky Mountain White" tilapia is often grown due to its very light flesh and tolerance of low temperatures. Commercially grown tilapia are almost exclusively male, typically done by adding male sex hormone in the food to the tilapia fry , causing any potential female tilapia to change sex to male. It can also be achieved through hybridization of certain tilapia species or

2520-730: Is based on the Portuguese spoken in the area including and surrounding the cities of Coimbra and Lisbon , in central Portugal. 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

2625-412: Is considerably intelligible for lusophones, owing to their genealogical proximity and shared genealogical history as West Iberian ( Ibero-Romance languages ), historical contact between speakers and mutual influence, shared areal features as well as modern lexical, structural, and grammatical similarity (89%) between them. Portuñol /Portunhol, a form of code-switching , has a more lively use and

2730-508: Is either mandatory, or taught, in the schools of those South American countries. Although early in the 21st century, after Macau was returned to China and immigration of Brazilians of Japanese descent to Japan slowed down, the use of Portuguese was in decline in Asia , it is once again becoming a language of opportunity there, mostly because of increased diplomatic and financial ties with economically powerful Portuguese-speaking countries in

2835-557: Is more readily mentioned in popular culture in South America. Said code-switching is not to be confused with the Portuñol spoken on the borders of Brazil with Uruguay ( dialeto do pampa ) and Paraguay ( dialeto dos brasiguaios ), and of Portugal with Spain ( barranquenho ), that are Portuguese dialects spoken natively by thousands of people, which have been heavily influenced by Spanish. Tilapia Traditionally

Portuguese speakers will usually need some formal study before attaining strong comprehension in those Romance languages, and vice versa. However, Portuguese and Galician are fully mutually intelligible, and Spanish

3990-776: The pre-Roman inhabitants of Portugal , which included the Gallaeci , Lusitanians , Celtici and Cynetes . 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

4095-510: The -s- form. Most of the lexicon of Portuguese is derived, directly or through other Romance languages, from Latin. Nevertheless, because of its original Lusitanian and Celtic Gallaecian heritage, and the later participation of Portugal in the Age of Discovery , it has a relevant number of words from the ancient Hispano-Celtic group and adopted loanwords from other languages around the world. A number of Portuguese words can still be traced to

4410-465: The 15th century, the Portuguese maritime explorations led to the introduction of many loanwords from Asian languages. For instance, catana (' cutlass ') from Japanese katana , chá ('tea') from Chinese chá , and canja ('chicken-soup, piece of cake') from Malay . From the 16th to the 19th centuries, because of the role of Portugal as intermediary in the Atlantic slave trade , and

Você , a pronoun meaning "you", is used for educated, formal, and colloquial respectful speech in most Portuguese-speaking regions. In a few Brazilian states such as Rio Grande do Sul , Pará, among others, você is virtually absent from the spoken language. Riograndense and European Portuguese normally distinguishes formal from informal speech by verbal conjugation. Informal speech employs tu followed by second person verbs, formal language retains

They consume floating aquatic plants, such as duckweed watermeal ( Lemna spp.), most "undesirable" submerged plants, and most forms of algae. In the United States and countries such as Thailand , they are becoming the plant-control method of choice, reducing or eliminating

5880-511: The blue tilapia, Oreochromis aureus , has the greatest cold tolerance and dies at 7 °C (45 °F), while all other species of tilapia die at a range of 11 to 17 °C (52 to 62 °F). As a result, they cannot invade temperate habitats and disrupt native ecologies in temperate zones; however, they have spread widely beyond their points of introduction in many fresh and brackish tropical and subtropical habitats, often disrupting native species significantly. Because of this, tilapia are on

Guided by these findings, tilapia farming techniques could be adjusted to address the nutritional criticisms directed at the fish, while retaining its advantage as an omnivore capable of feeding on economically and environmentally inexpensive vegetable protein. Adequate diets for salmon and other carnivorous fish can alternatively be formulated from protein sources such as soybean , although soy-based diets with soy oil may also change in

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

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

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

8085-486: The only language used in any contact, to only education, contact with local or international administration, commerce and services or the simple sight of road signs, public information and advertising in Portuguese.

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.

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

10920-585: Was the loss of intervocalic l and n , sometimes followed by the merger of the two surrounding vowels, or by the insertion of an epenthetic vowel between them: cf. 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 .
