Aquaculture In Chile
Aquaculture is a major economic activity in Chile. Among the diverse aquacultures practised in Chile, Atlantic salmon aquaculture is by far the largest sector. Apart from salmon and trout, Chilean aquaculture also produces turbots and molluscs, in particular '' Mytilus platensis'' (still often referred to as ''Mytilus chilensis''), Northern scallops, Pacific oysters, '' Aulacomya ater'' (a giant mussel), red abalone, and Chilean oysters. In terms of algae ''Gracillaria chilensis'' is cultivated and harvested. The main areas of aquaculture in Chile lie in the southern half of the country in particular in the interior waters of Los Lagos Region and to a lesser extent the fjords and channels of more southern Aysén and Magallanes regions. Salmon Up until 2007, Chile experienced over 15 years of important growth in its salmon aquaculture, becoming the second largest salmon and trout producer after Norway.

Fjord
In physical geography, a fjord or fiord () is a long, narrow inlet with steep sides or cliffs, created by a glacier. Fjords exist on the coasts of Alaska, Antarctica, British Columbia, Chile, Denmark, Germany, Greenland, the Faroe Islands, Iceland, Ireland, Kamchatka, the Kerguelen Islands, Labrador, Newfoundland, New Zealand, Norway, Novaya Zemlya, Nunavut, Quebec, the Patagonia region of Argentina and Chile, Russia, South Georgia Island, Tasmania, United Kingdom, and Washington state. Norway's coastline is estimated to be long with its nearly 1,200 fjords, but only long excluding the fjords. Formation A true fjord is formed when a glacier cuts a U-shaped valley by ice segregation and abrasion of the surrounding bedrock. According to the standard model, glaciers formed in pre-glacial valleys with a gently sloping valley floor. The work of the glacier then left an overdeepened U-shaped valley that ends abruptly at a valley or trough end. Such valleys are fjords wh ...

Ministry Of National Defense (Chile)
The Ministry of National Defense ( es, Ministerio de Defensa Nacional) is the cabinet-level administrative office in charge of "maintaining the independence and sovereignty" of Chile. It is also charged with planning, directing, coordinating, executing, controlling and informing the defense policies formulated by the President of Chile. The minister supervises all the Military of Chile, Chilean armed forces. It is Chile's ministry of defence. History During the first days of the independence movements, the senior "secretary" of the respective List of Government Juntas of Chile, Junta would function as the ''Secretary of Government'' with administrative power over the army. The office officially first came to be on 17 March 1814, when then Supreme Director Francisco de la Lastra dictated the Constitutional Norms approved on that date. It was then named ''Secretariat of War''. It was abolished the same year by the Spanish authorities when, after the Battle of Rancagua, they re-as ...

Concession (contract)
A concession or concession agreement is a grant of rights, land or property by a government, local authority, corporation, individual or other legal entity. Public services such as water supply may be operated as a concession. In the case of a public service concession, a private company enters into an agreement with the government to have the exclusive right to operate, maintain and carry out investment in a public utility (such as a water privatisation) for a given number of years. Other forms of contracts between public and private entities, namely lease contract and management contract (in the water sector often called by the French term ''affermage''), are closely related but differ from a concession in the rights of the operator and its remuneration. A lease gives a company the right to operate and maintain a public utility, but investment remains the responsibility of the public. Under a management contract the operator will collect the revenue only on behalf of the govern ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Red Tide
A harmful algal bloom (HAB) (or excessive algae growth) is an algal bloom that causes negative impacts to other organisms by production of natural phycotoxin, algae-produced toxins, mechanical damage to other organisms, or by other means. HABs are sometimes defined as only those algal blooms that produce toxins, and sometimes as any algal bloom that can result in severely lower oxygen saturation, oxygen levels in natural waters, killing organisms in marine habitats, marine or fresh waters. Blooms can last from a few days to many months. After the bloom dies, the microorganism, microbes that decompose the dead algae use up more of the oxygen, generating a "dead zone (ecology), dead zone" which can cause fish kill, fish die-offs. When these zones cover a large area for an extended period of time, neither fish nor plants are able to survive. Harmful algal blooms in marine environments are often called "red tides". It is sometimes unclear what causes specific HABs as their occurrence ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Infectious Salmon Anemia
Infectious salmon anemia (ISA) is a viral disease of Atlantic salmon (''Salmo salar'') caused by ''Salmon isavirus''. It affects fish farms in Canada, Norway, Scotland and Chile, causing severe losses to infected farms. ISA has been a World Organisation for Animal Health notifiable disease since 1990. In the EU, it is classified as a non-exotic disease, and is monitored by the European Community Reference Laboratory for Fish Diseases. Virology ISA is caused by the infectious salmon anemia virus (ISAV). ISAV, a segmented RNA virus that is the only species in the genus "Isavirus", which is in the family Orthomyxoviridae, and therefore related to the influenza viruses. The genome encodes at least 10 proteins. There are several distinct strains of the virus. The most common are a European strain and a North American strain. Pathology ISA virus causes severe anemia in infected fish. Unlike the mature red blood cells of mammals, the mature red blood cells of fish contain DNA, ...

Florfenicol
Florfenicol (marketed by Schering-Plough Animal Health under the trade name Nuflor) is a fluorinated synthetic analog of thiamphenicol, mainly used in veterinary medicine. As a generic, it is now available worldwide. Indications In the United States, florfenicol is currently indicated for the treatment of bovine respiratory disease (BRD) associated with ''Mannheimia haemolytica'', ''Pasteurella multocida'', and ''Histophilus somni'', for treatment of bovine interdigital phlegmon (foot rot, acute interdigital necrobacillosis, infectious pododermatitis) associated with ''Fusobacterium necrophorum'' and ''Bacteroides melaninogenicus''. Florfenicol is also used in aquaculture, and is licensed for use in the United States for the control of enteric septicemia in catfish. Since the early 2000s, it is used in Europe, treating mainly primary or secondary colibacillosis in broiler and parent flocks. It is not allowed in laying hens, due to residues in eggs. It is also indicated in tu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Molybdenum
Molybdenum is a chemical element with the symbol Mo and atomic number 42 which is located in period 5 and group 6. The name is from Neo-Latin ''molybdaenum'', which is based on Ancient Greek ', meaning lead, since its ores were confused with lead ores. Molybdenum minerals have been known throughout history, but the element was discovered (in the sense of differentiating it as a new entity from the mineral salts of other metals) in 1778 by Carl Wilhelm Scheele. The metal was first isolated in 1781 by Peter Jacob Hjelm. Molybdenum does not occur naturally as a free metal on Earth; it is found only in various oxidation states in minerals. The free element, a silvery metal with a grey cast, has the sixth-highest melting point of any element. It readily forms hard, stable carbides in alloys, and for this reason most of the world production of the element (about 80%) is used in steel alloys, including high-strength alloys and superalloys. Most molybdenum compounds have low solubili ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Copper
Copper is a chemical element with the symbol Cu (from la, cuprum) and atomic number 29. It is a soft, malleable, and ductile metal with very high thermal and electrical conductivity. A freshly exposed surface of pure copper has a pinkish-orange color. Copper is used as a conductor of heat and electricity, as a building material, and as a constituent of various metal alloys, such as sterling silver used in jewelry, cupronickel used to make marine hardware and coins, and constantan used in strain gauges and thermocouples for temperature measurement. Copper is one of the few metals that can occur in nature in a directly usable metallic form ( native metals). This led to very early human use in several regions, from circa 8000 BC. Thousands of years later, it was the first metal to be smelted from sulfide ores, circa 5000 BC; the first metal to be cast into a shape in a mold, c. 4000 BC; and the first metal to be purposely alloyed with another metal, tin, to create ...
