Prochilodus Lineatus
''Prochilodus lineatus'', the streaked prochilod, is a species of ray-finned fish in the family Prochilodontidae. It is native to the Paraná—Paraguay and Paraíba do Sul river basins in South America. It performs long breeding migrations and supports very important fisheries. Local names In Spanish its common name is ''sábalo''; in Brazil it receives the names ''curimbatá'', ''curimba'', ''corimbatá'' or ''grumatã''.In the United States it is also known by the technical synonym ''Tarpon prochilodus''. There are mother species of fish with the common name '' sábalo''; ''P. lineatus'' is therefore distinguished sometimes as ''sábalo jetón'' (colloquial Spanish for "big-mouth") or ''chupabarro'' ("mud-sucker"). Appearance ''P. lineatus'' reaches up to in length and in weight. A common length is about . Its body is tall and compressed, greenish-gray (lighter in the belly), with yellowish green fins. Its mouth is circular and projects towards the front; it has two seri ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Achille Valenciennes
Achille Valenciennes (9 August 1794 – 13 April 1865) was a French zoologist. Valenciennes was born in Paris, and studied under Georges Cuvier. His study of parasitic worms in humans made an important contribution to the study of parasitology. He also carried out diverse systematic classifications, linking fossil and current species. He worked with Cuvier on the 22-volume "'' Histoire Naturelle des Poissons''" (Natural History of Fish) (1828–1848), carrying on alone after Cuvier died in 1832. In 1832, he succeeded Henri Marie Ducrotay de Blainville (1777–1850) as chair of ''Histoire naturelle des mollusques, des vers et des zoophytes'' at the Muséum national d'histoire naturelle. Early in his career, he was given the task of classifying animals described by Alexander von Humboldt (1769–1859) during his travels in the American tropics (1799 to 1803), and a lasting friendship was established between the two men. He is the binomial authority for many species of fish, such a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Export
An export in international trade is a good produced in one country that is sold into another country or a service provided in one country for a national or resident of another country. The seller of such goods or the service provider is an ''exporter''; the foreign buyer is an '' importer''. Services that figure in international trade include financial, accounting and other professional services, tourism, education as well as intellectual property rights. Exportation of goods often requires the involvement of customs authorities. Firms Many manufacturing firms begin their global expansion as exporters and only later switch to another mode for serving a foreign market. Barriers There are four main types of export barriers: motivational, informational, operational/resource-based, and knowledge. Trade barriers are laws, regulations, policy, or practices that protect domestically made products from foreign competition. While restrictive business practices sometimes hav ...

Freshwater Fish Of Argentina
Fresh water or freshwater is any naturally occurring liquid or frozen water containing low concentrations of dissolved salts and other total dissolved solids. Although the term specifically excludes seawater and brackish water, it does include non- salty mineral-rich waters such as chalybeate springs. Fresh water may encompass frozen and meltwater in ice sheets, ice caps, glaciers, snowfields and icebergs, natural precipitations such as rainfall, snowfall, hail/ sleet and graupel, and surface runoffs that form inland bodies of water such as wetlands, ponds, lakes, rivers, streams, as well as groundwater contained in aquifers, subterranean rivers and lakes. Fresh water is the water resource that is of the most and immediate use to humans. Water is critical to the survival of all living organisms. Many organisms can thrive on salt water, but the great majority of higher plants and most insects, amphibians, reptiles, mammals and birds need fresh water to survive. ...

Fish Of South America
Fish are aquatic, craniate, gill-bearing animals that lack limbs with digits. Included in this definition are the living hagfish, lampreys, and cartilaginous and bony fish as well as various extinct related groups. Approximately 95% of living fish species are ray-finned fish, belonging to the class Actinopterygii, with around 99% of those being teleosts. The earliest organisms that can be classified as fish were soft-bodied chordates that first appeared during the Cambrian period. Although they lacked a true spine, they possessed notochords which allowed them to be more agile than their invertebrate counterparts. Fish would continue to evolve through the Paleozoic era, diversifying into a wide variety of forms. Many fish of the Paleozoic developed external armor that protected them from predators. The first fish with jaws appeared in the Silurian period, after which many (such as sharks) became formidable marine predators rather than just the prey of arthropods. Most f ...

Unemployment
Unemployment, according to the OECD (Organisation for Economic Co-operation and Development), is people above a specified age (usually 15) not being in paid employment or self-employment but currently available for Work (human activity), work during the reference period. Unemployment is measured by the unemployment rate, which is the number of people who are unemployed as a percentage of the labour force (the total number of people employed added to those unemployed). Unemployment can have many sources, such as the following: * new technology, technologies and inventions * the status of the economy, which can be influenced by a recession * competition caused by globalization and international trade * Policy, policies of the government * regulation and market (economics), market Unemployment and the status of the economy can be influenced by a country through, for example, fiscal policy. Furthermore, the monetary authority of a country, such as the central bank, can influ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Victoria, Entre Ríos
Victoria is a city located in the southwestern part of the province of Entre Ríos, Argentina. It is located on the eastern shore of the Paraná River, opposite Rosario, Santa Fe, to which it has been connected since 2003 by the Rosario-Victoria Bridge (which spans almost 60 km over the flood plain of the Paraná Delta). The site of a 1750 defeat of a native uprising and an 1810 oratory to the Virgin of Aranzazú, a Marian apparition and the city's patron saint, ''Cerro La Matanza'' was granted Village status by the Provincial Legislature, in 1826. An 1829 edict renamed the hamlet ''Victoria''. The church (started in 1872) is dedicated to this patron. Designated a "city" in 1851, Victoria also features an abbey ('' Abadía Los Monjes del Niño Dios''), founded by Benedictine monks who arrived in 1899. The Victoria region is at the core of the fishing industry of commercially important species like sábalo (''Prochilodus lineatus'') and surubí (''Pseudoplatystoma spp.' ...

Rosario-Victoria Bridge
Rosario-Victoria Bridge (in Spanish, ''Puente Rosario-Victoria'') is the informal name of the physical connection between the Argentine cities of Rosario (province of Santa Fe) and Victoria (province of Entre Ríos). This roadlink is composed of several bridges, viaducts and earth-filled sections. It crosses the main course of the Paraná River and touches down on several islands of the Paraná Delta in the way. Works on the project began in 1998, but they were repeatedly interrupted due to lack of continued funding from the national and the provincial state, especially in the worst part of the Argentine economic crisis of 2001. Public transit access to the bridge was opened on May 22, 2003. The link between the two cities spans a total of 59.4 kilometers (37 mi). The total length of the various bridges and their viaducts is 12.2 km (7.5 mi). The main bridge is 4,098 meters (13,440 ft) long, with central cable-stayed span of 350 meters (1,148 ft). ...

Environmental Movement
The environmental movement (sometimes referred to as the ecology movement), also including conservation and green politics, is a diverse philosophical, social, and political movement for addressing environmental issues. Environmentalists advocate the just and sustainable management of resources and stewardship of the environment through changes in public policy and individual behaviour. In its recognition of humanity as a participant in (not enemy of) ecosystems, the movement is centered on ecology, health, and human rights. The environmental movement is an international movement, represented by a range of organizations, from enterprises to grassroots and varies from country to country. Due to its large membership, varying and strong beliefs, and occasionally speculative nature, the environmental movement is not always united in its goals. The movement also encompasses some other movements with a more specific focus, such as the climate movement. At its broadest, the ...

Fishing Net
A fishing net is a net used for fishing. Nets are devices made from fibers woven in a grid-like structure. Some fishing nets are also called fish traps, for example fyke nets. Fishing nets are usually meshes formed by knotting a relatively thin thread. Early nets were woven from grasses, flaxes and other fibrous plant material. Later cotton was used. Modern nets are usually made of artificial polyamides like nylon, although nets of organic polyamides such as wool or silk thread were common until recently and are still used. History Fishing nets have been used widely in the past, including by stone age societies. The oldest known fishing net is the net of Antrea, found with other fishing equipment in the Karelian town of Antrea, Finland, in 1913. The net was made from willow, and dates back to 8300 BC. Recently, fishing net sinkers from 27,000 BC were discovered in Korea, making them the oldest fishing implements discovered, to date, in the world. The remnants of another f ...

Argentine Economic Crisis (1999-2002)
Argentines (mistakenly translated Argentineans in the past; in Spanish (masculine) or ( feminine)) are people identified with the country of Argentina. This connection may be residential, legal, historical or cultural. For most Argentines, several (or all) of these connections exist and are collectively the source of their being ''Argentine''. Argentina is a multiethnic and multilingual society, home to people of various ethnic, religious, and national origins, with the majority of the population made up of Old World immigrants and their descendants. As a result, Argentines do not equate their nationality with ethnicity, but with citizenship and allegiance to Argentina. Aside from the indigenous population, nearly all Argentines or their ancestors immigrated within the past five centuries. Among countries in the world that have received the most immigrants in modern history, Argentina, with 6.6 million, ranks second to the United States (27 million), and ahead of other immig ...

Argentine Peso
The peso (established as the ''peso convertible'') is the currency of Argentina, identified by the symbol $ preceding the amount in the same way as many countries using peso or dollar currencies. It is subdivided into 100 '' centavos''. Its ISO 4217 code is ARS. The Argentine currency has experienced severe inflation, with periods of hyperinflation, since the mid-20th century, with periodic change of the currency to a new version at a rate ranging from 100:1 to 10,000:1. The peso introduced in 1992 was worth 10,000,000,000,000 (ten trillion) of the pesos in use until 1970. Since the early 21st century, the Argentine peso has experienced a substantial rate of devaluation, reaching over 51% year-on-year inflation rate in 2021. The official exchange rate for the United States dollar commenced at 1:1 at the peso's introduction in 1992; it then hovered around 3:1 from 2002 to 2008, before climbing from 6:1 to 10:1 between 2009 and 2015. In July 2022, the value exchange rate with the U ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
