Barley, a member of the grass family, is a major cereal grain grown in temperate climates globally. It was one of the first cultivated grains in Eurasia as early as 10,000 years ago. Barley has been used as animal fodder, as a source of fermentable material for beer and certain distilled beverages, as a component of various health foods, it is used in soups and stews, in barley bread of various cultures. Barley grains are made into malt in a traditional and ancient method of preparation. In 2016, barley was ranked fourth among grains in quantity produced behind maize and wheat; the Old English word for'barley' was bære, which traces back to Proto-Indo-European and is cognate to the Latin word farina "flour". The direct ancestor of modern English "barley" in Old English was the derived adjective bærlic, meaning "of barley"; the first citation of the form bærlic in the Oxford English Dictionary dates to around 966 CE, in the compound word bærlic-croft. The underived word bære survives in the north of Scotland as bere, refers to a specific strain of six-row barley grown there.
The word barn, which meant "barley-house", is rooted in these words. Barley is a member of the grass family, it is a diploid species with 14 chromosomes. The wild ancestor of domesticated barley, Hordeum vulgare subsp. Spontaneum, is abundant in grasslands and woodlands throughout the Fertile Crescent area of Western Asia and northeast Africa, is abundant in disturbed habitats and orchards. Outside this region, the wild barley is less common and is found in disturbed habitats. However, in a study of genome-wide diversity markers, Tibet was found to be an additional center of domestication of cultivated barley. Wild barley is the ancestor of domestic barley. Over the course of domestication, barley grain morphology changed moving from an elongated shape to a more rounded spherical one. Additionally, wild barley has distinctive genes and regulators with potential for resistance to abiotic or biotic stresses to cultivated barley and adaptation to climatic changes. Wild barley has a brittle spike. Domesticated barley has nonshattering spikes.
The nonshattering condition is caused by a mutation in one of two linked genes known as Bt1 and Bt2. The nonshattering condition is recessive, so varieties of barley that exhibit this condition are homozygous for the mutant allele; each plant gets a set of genes from both parents, so two copies of each gene are in every plant. If one gene copy is a nonworking mutant, but the other gene copy works, the mutation has no effect. Only when the plant is homozygous with both copies of the gene as nonworking mutants does the mutation show its effect by exhibiting the nonshattering condition. Domestication in barley is followed by the change of key phenotypic traits at the genetic level. Little is known about the genetic variation among domesticated and wild genes in the chromosomal regions. Spikelets are arranged in triplets. In wild barley, only the central spikelet is fertile; this condition is retained in certain cultivars known as two-row barleys. A pair of mutations result in fertile lateral spikelets to produce six-row barleys.
Recent genetic studies have revealed that a mutation in one gene, vrs1, is responsible for the transition from two-row to six-row barley. Two-row barley has a lower protein content than six-row barley, thus a more fermentable sugar content. High-protein barley is best suited for animal feed. Malting barley is lower protein which shows more uniform germination, needs shorter steeping, has less protein in the extract that can make beer cloudy. Two-row barley is traditionally used in English ale-style beers, with two-row malted summer barley being preferred for traditional German beers. Six-row barley is common in some American lager-style beers when adjuncts such as corn and rice are used. Hulless or "naked" barley is a form of domesticated barley with an easier-to-remove hull. Naked barley is an ancient food crop, but a new industry has developed around uses of selected hulless barley to increase the digestible energy of the grain for swine and poultry. Hulless barley has been investigated for several potential new applications as whole grain, for its value-added products.
These include flour for multiple food applications. In traditional classifications of barley, these morphological differences have led to different forms of barley being classified as different species. Under these classifications, two-row barley with shattering spikes is classified as Hordeum spontaneum K. Koch. Two-row barley with nonshattering spikes is classified as H. distichum L. six-row barley with nonshattering spikes as H. vulgare L. and six-row with shattering spikes as H. agriocrithon Åberg. Because these differences were driven by single-gene mutations, coupled with cytological and molecular evidence, most recent classifications treat these forms as a single species, H. vulgare L. VocabularyDON: Acronym for deoxynivalenol, a toxic byproduct of Fusarium head blight known as vomitoxin Heading date: A parameter in barley cultivation Lodging: The bending over of the stems near ground level Nutans: A designation for a variety with a lax ear, as opposed to'erectum' (with an erect ea
A bean is a seed of one of several genera of the flowering plant family Fabaceae, which are used for human or animal food. The word "bean" and its Germanic cognates have existed in common use in West Germanic languages since before the 12th century, referring to broad beans and other pod-borne seeds; this was long. After Columbian-era contact between Europe and the Americas, use of the word was extended to pod-borne seeds of Phaseolus, such as the common bean and the runner bean, the related genus Vigna; the term has long been applied to many other seeds of similar form, such as Old World soybeans, chickpeas, other vetches, lupins, to those with slighter resemblances, such as coffee beans, vanilla beans, castor beans, cocoa beans. Thus the term "bean" in general usage can mean a host of different species. Seeds called "beans" are included among the crops called "pulses", although a narrower prescribed sense of "pulses" reserves the word for leguminous crops harvested for their dry grain; the term bean excludes legumes with tiny seeds and which are used for forage and silage purposes.
According to the United Nations Food and Agriculture Organization the term "BEANS, DRY" should include only species of Phaseolus. One is that in the past, several species, including Vigna angularis, mungo and aconitifolia, were classified as Phaseolus and reclassified. Another is that it is not surprising that the prescription on limiting the use of the word, because it tries to replace the word's older senses with a newer one, has never been followed in general usage. Unlike the related pea, beans are a summer crop that need warm temperatures to grow. Maturity is 55–60 days from planting to harvest; as the bean pods mature, they turn yellow and dry up, the beans inside change from green to their mature colour. As a vine, bean plants need external support, which may be provided in the form of special "bean cages" or poles. Native Americans customarily grew them along with corn and squash, with the tall cornstalks acting as support for the beans. In more recent times, the so-called "bush bean" has been developed which does not require support and has all its pods develop simultaneously.
This makes the bush bean more practical for commercial production. Beans are one of the longest-cultivated plants. Broad beans called fava beans, in their wild state the size of a small fingernail, were gathered in Afghanistan and the Himalayan foothills. In a form improved from occurring types, they were grown in Thailand since the early seventh millennium BCE, predating ceramics, they were deposited with the dead in ancient Egypt. Not until the second millennium BCE did cultivated, large-seeded broad beans appear in the Aegean and transalpine Europe. In the Iliad is a passing mention of beans and chickpeas cast on the threshing floor. Beans were an important source of protein throughout Old and New World history, still are today; the oldest-known domesticated beans in the Americas were found in Guitarrero Cave, an archaeological site in Peru, dated to around the second millennium BCE. However, genetic analyses of the common bean Phaseolus shows that it originated in Mesoamerica, subsequently spread southward, along with maize and squash, traditional companion crops.
Most of the kinds eaten fresh or dried, those of the genus Phaseolus, come from the Americas, being first seen by a European when Christopher Columbus, during his exploration of what may have been the Bahamas, found them growing in fields. Five kinds of Phaseolus beans were domesticated by pre-Columbian peoples: common beans grown from Chile to the northern part of what is now the United States, lima and sieva beans, as well as the less distributed teparies, scarlet runner beans and polyanthus beans One famous use of beans by pre-Columbian people as far north as the Atlantic seaboard is the "Three Sisters" method of companion plant cultivation: In the New World, many tribes would grow beans together with maize, squash; the corn would not be planted in rows as is done by European agriculture, but in a checkerboard/hex fashion across a field, in separate patches of one to six stalks each. Beans would be planted around the base of the developing stalks, would vine their way up as the stalks grew.
All American beans at that time were vine plants, "bush beans" having been bred only more recently. The cornstalks would work as a trellis for the beans, the beans would provide much-needed nitrogen for the corn. Squash would be planted in the spaces between the patches of corn in the field, they would be provided slight shelter from the sun by the corn, would shade the soil and reduce evaporation, would deter many animals from attacking the corn and beans because their coarse, hairy vines and broad, stiff leaves are difficult or uncomfortable for animals such as deer and raccoons to walk through, crows to land on, etc. Dry beans come from both Old World varieties of New World varieties. Beans are a heliotropic plant. At night, they go into a folded "sleep" position; the world genebanks hold about 40,000 bean varieties, although on
The Pacific War, sometimes called the Asia–Pacific War, was the theater of World War II, fought in the Pacific and Asia. It was fought over a vast area that included the Pacific Ocean and islands, the South West Pacific, South-East Asia, in China; the Second Sino-Japanese War between the Empire of Japan and the Republic of China had been in progress since 7 July 1937, with hostilities dating back as far as 19 September 1931 with the Japanese invasion of Manchuria. However, it is more accepted that the Pacific War itself began on 7/8 December 1941, when Japan invaded Thailand and attacked the British colonies of Malaya and Hong Kong as well as the United States military and naval bases in Hawaii, Wake Island and the Philippines; the Pacific War saw the Allies pitted against Japan, the latter aided by Thailand and to a much lesser extent by the Axis allied Germany and Italy. The war culminated in the atomic bombings of Hiroshima and Nagasaki, other large aerial bomb attacks by the Allies, accompanied by the Soviet declaration of war and invasion of Manchuria on 9 August 1945, resulting in the Japanese announcement of intent to surrender on 15 August 1945.
The formal surrender of Japan ceremony took place aboard the battleship USS Missouri in Tokyo Bay on 2 September 1945. After the war, Japan lost all rights and titles to its former possessions in Asia and the Pacific, its sovereignty was limited to the four main home islands. Japan's Shinto Emperor was forced to relinquish much of his authority and his divine status through the Shinto Directive in order to pave the way for extensive cultural and political reforms. In Allied countries during the war, the "Pacific War" was not distinguished from World War II in general, or was known as the War against Japan. In the United States, the term Pacific Theater was used, although this was a misnomer in relation to the Allied campaign in Burma, the war in China and other activities within the Southeast Asian Theater. However, the US Armed Forces considered the China-Burma-India Theater to be distinct from the Asiatic-Pacific Theater during the conflict. Japan used the name Greater East Asia War, as chosen by a cabinet decision on 10 December 1941, to refer to both the war with the Western Allies and the ongoing war in China.
This name was released to the public on 12 December, with an explanation that it involved Asian nations achieving their independence from the Western powers through armed forces of the Greater East Asia Co-Prosperity Sphere. Japanese officials integrated what they called the Japan–China Incident into the Greater East Asia War. During the Allied military occupation of Japan, these Japanese terms were prohibited in official documents, although their informal usage continued, the war became known as the Pacific War. In Japan, the Fifteen Years' War is used, referring to the period from the Mukden Incident of 1931 through 1945; the Axis states which assisted Japan included the authoritarian government of Thailand, which formed a cautious alliance with the Japanese in 1941, when Japanese forces issued the government with an ultimatum following the Japanese invasion of Thailand. The leader of Thailand, Plaek Phibunsongkhram, became enthusiastic about the alliance after decisive Japanese victories in the Malayan Campaign and in 1942 sent the Phayap Army to assist the invasion of Burma, were former Thai territory, annexed by Britain were reoccupied.
The allies supported and organized an underground anti-Japanese resistance group, known as the Free Thai Movement, after the Thai ambassador to the United States had refused to hand over the declaration of war. Because of this, after the surrender in 1945, the stance of the United States was that Thailand should be treated as a puppet of Japan and be considered an occupied nation rather than as an ally; this was done in contrast to the British stance towards Thailand, who had faced them in combat as they invaded British territory, the United States had to block British efforts to impose a punitive peace. Involved were members of the Greater East Asia Co-Prosperity Sphere, which included the armies of the Japanese puppet states of Manchukuo, the collaborationist Wang Jingwei regime. In the Burma Campaign, other members, such as the anti-Britsh Indian National Army of Free India and Burma National Army of the State of Burma were active and fighting alongside their Japanese allies. Moreover, Japan conscripted many soldiers from its colonies of Taiwan.
Collaborationist security units were formed in Hong Kong, the Philippines, Dutch East Indies, British Malaya, British Borneo, former French Indochina as well as Timorese militia. These units the assisted Japanese war effort in their respective territories. Germany and Italy both had limited involvement in the Pacific War; the German and the Italian navies operated submarines and raiding ships in the Indian and Pacific Oceans. The Italians had access to concession territory naval bases in China. After Japan's attack on Pearl Harbor and the subsequent declarations of war, both navies had access to Japanese naval facilities; the major Allied participants were the United States and their colonies, the Republic of China, engaged in bloody war against Japan since 1937, the United Kingdom (mos
Tsukiji fish market
The Tsukiji Market, supervised by the Tokyo Metropolitan Central Wholesale Market of the Tokyo Metropolitan Bureau of Industrial and Labor Affairs, was the largest wholesale fish and seafood market in the world. It was one of the largest wholesale food markets of any kind; the market opened on 11 February 1935 as a replacement for an older market destroyed in the 1923 Great Kantō earthquake, closed on 6 October 2018 to move to the new Toyosu Market, 2.4 kilometres away. The market was located in Tsukiji in central Tokyo between the Sumida River and the upmarket Ginza shopping district. While the inner wholesale market had restricted access to visitors, the outer retail market and associated restaurant supply stores remain a major tourist attraction for both domestic and overseas visitors; the market is located near the Tsukijishijō Station on the Toei Ōedo Line and Tsukiji Station on the Tokyo Metro Hibiya Line. There are two distinct sections of the market as a whole; the "inner market" is the licensed wholesale market, where 900 licensed wholesale dealers operate small stalls and where the auctions and most of the processing of the fish take place.
The "outer market" is a mixture of wholesale and retail shops that sell Japanese kitchen tools, restaurant supplies and seafood, many restaurants sushi restaurants. Most of the shops in the outer market closed by the early afternoon. In the inner market visitors were only allowed in by 10.00 am, by which time the activity in the market had reduced or ceased. A small number of visitors however were allowed into the inner market in the early morning to see the tuna auction; the land on which the fish market sat was created during the Edo period by the Tokugawa shogunate after the Great fire of Meireki of 1657. It was created through land reclamation on the Tokyo Bay, the area was therefore named Tsukiji, meaning "constructed land" or "reclaimed land"; the fish market however was not sited here until the 20th century. The first fish market in Tokyo was located in the Nihonbashi district, next to the Nihonbashi bridge that gave the area its name; the area was one of the earliest places to be settled when Edo was made the capital by Tokugawa Ieyasu, the market provided food for the Edo castle built on a nearby hill.
Tokugawa Ieyasu took a number of fishermen from Tsukuda, Osaka to Edo to provide fish for the castle in 1590. Fish not bought by the castle was sold near the Nihonbashi bridge, at a market called uogashi. In August 1918, following the so-called "Rice Riots", which broke out in over 100 cities and towns in protest against food shortages and the speculative practices of wholesalers, the Japanese government was forced to create new institutions for the distribution of foodstuffs in urban areas. A Central Wholesale Market Law was established in March 1923; the Great Kantō earthquake on 1 September 1923 devastated much of central Tokyo, including the Nihonbashi fish market. The Tokyo government, which had plans to relocate the market due to its unsanitary conditions considered unsuitable for an area that had developed into a business center took the opportunity to move the market to the Tsukiji district. Following the 1923 Great Kantō earthquake architects and engineers from the Architectural Section of Tokyo Municipal Government were sent to Europe and America to do research for the new market.
However, because of the sheer size of the market and the number of items traded they were forced to come up with their own unique design. The quarter circular shape allowed easier access and handling for freight trains and the steel structure above allowed a wide, continuous space free from columns and subdivisions; the relocation of the market would be one of the biggest reconstruction projects in Tokyo after the earthquake, taking over six years involving 419,500 workers. Tsukiji was opened on February 11, 1935. After the modern market facility was completed in 1935, the fish market in Tsukiji began operations under the provisions of the 1923 Central Wholesale Market Law, along with two other major markets in Kanda and Koto. Smaller branch markets were established in Ebara and Adachi, elsewhere. At present, the Tokyo Metropolitan Government's system of wholesale markets includes more than a dozen major and branch markets, handling seafood, produce and cut flowers; the Tsukiji fish market occupies valuable real estate close to the center of the city.
Former Tokyo Governor Shintaro Ishihara called for moving the market to Toyosu, Koto. The long-anticipated move to the new Toyosu Market was scheduled to take place in November 2016, in preparation for the 2020 Summer Olympics, but on August 31, 2016, the move was postponed. There had been concerns that new location was polluted and needed to be cleaned up. There are plans to retain a retail market a quarter of the current operation, in Tsukiji; the remaining area of the market will be redeveloped. In June 2017, plans to move the fish market were restarted, but delayed in July to the autumn of 2018. On August 3, 2017, a fire broke out in some of the outer buildings. After the new site had been declared safe following a cleanup operation, the opening date of the new market was set for 11 October 2018. Tsukiji market closed on 6 October 2018, with the businesses of the inner market relocated to the new Toyosu Market between 6 and 11 October. Though Tsukiji inner market has moved to Toyosu, the so-called outer market remains, selling food and other goods.

The United States of America known as the United States or America, is a country composed of 50 states, a federal district, five major self-governing territories, various possessions. At 3.8 million square miles, the United States is the world's third or fourth largest country by total area and is smaller than the entire continent of Europe's 3.9 million square miles. With a population of over 327 million people, the U. S. is the third most populous country. The capital is Washington, D. C. and the largest city by population is New York City. Forty-eight states and the capital's federal district are contiguous in North America between Canada and Mexico; the State of Alaska is in the northwest corner of North America, bordered by Canada to the east and across the Bering Strait from Russia to the west. The State of Hawaii is an archipelago in the mid-Pacific Ocean; the U. S. territories are scattered about the Pacific Ocean and the Caribbean Sea, stretching across nine official time zones. The diverse geography and wildlife of the United States make it one of the world's 17 megadiverse countries.
Paleo-Indians migrated from Siberia to the North American mainland at least 12,000 years ago. European colonization began in the 16th century; the United States emerged from the thirteen British colonies established along the East Coast. Numerous disputes between Great Britain and the colonies following the French and Indian War led to the American Revolution, which began in 1775, the subsequent Declaration of Independence in 1776; the war ended in 1783 with the United States becoming the first country to gain independence from a European power. The current constitution was adopted in 1788, with the first ten amendments, collectively named the Bill of Rights, being ratified in 1791 to guarantee many fundamental civil liberties; the United States embarked on a vigorous expansion across North America throughout the 19th century, acquiring new territories, displacing Native American tribes, admitting new states until it spanned the continent by 1848. During the second half of the 19th century, the Civil War led to the abolition of slavery.
By the end of the century, the United States had extended into the Pacific Ocean, its economy, driven in large part by the Industrial Revolution, began to soar. The Spanish–American War and World War I confirmed the country's status as a global military power; the United States emerged from World War II as a global superpower, the first country to develop nuclear weapons, the only country to use them in warfare, a permanent member of the United Nations Security Council. Sweeping civil rights legislation, notably the Civil Rights Act of 1964, the Voting Rights Act of 1965 and the Fair Housing Act of 1968, outlawed discrimination based on race or color. During the Cold War, the United States and the Soviet Union competed in the Space Race, culminating with the 1969 U. S. Moon landing; the end of the Cold War and the collapse of the Soviet Union in 1991 left the United States as the world's sole superpower. The United States is the world's oldest surviving federation, it is a representative democracy.
The United States is a founding member of the United Nations, World Bank, International Monetary Fund, Organization of American States, other international organizations. The United States is a developed country, with the world's largest economy by nominal GDP and second-largest economy by PPP, accounting for a quarter of global GDP; the U. S. economy is post-industrial, characterized by the dominance of services and knowledge-based activities, although the manufacturing sector remains the second-largest in the world. The United States is the world's largest importer and the second largest exporter of goods, by value. Although its population is only 4.3% of the world total, the U. S. holds 31% of the total wealth in the world, the largest share of global wealth concentrated in a single country. Despite wide income and wealth disparities, the United States continues to rank high in measures of socioeconomic performance, including average wage, human development, per capita GDP, worker productivity.
The United States is the foremost military power in the world, making up a third of global military spending, is a leading political and scientific force internationally. In 1507, the German cartographer Martin Waldseemüller produced a world map on which he named the lands of the Western Hemisphere America in honor of the Italian explorer and cartographer Amerigo Vespucci; the first documentary evidence of the phrase "United States of America" is from a letter dated January 2, 1776, written by Stephen Moylan, Esq. to George Washington's aide-de-camp and Muster-Master General of the Continental Army, Lt. Col. Joseph Reed. Moylan expressed his wish to go "with full and ample powers from the United States of America to Spain" to seek assistance in the revolutionary war effort; the first known publication of the phrase "United States of America" was in an anonymous essay in The Virginia Gazette newspaper in Williamsburg, Virginia, on April 6, 1776. The second draft of the Articles of Confederation, prepared by John Dickinson and completed by June 17, 1776, at the latest, declared "The name of this Confederation shall be the'United States of America'".
The final version of the Articles sent to the states for ratification in late 1777 contains the sentence "The Stile of this Confederacy shall be'The United States of America'". In June 1776, Thomas Jefferson wrote the phrase "UNITED STATES OF AMERICA" in all capitalized letters in the headline of his "original Rough draught" of the Declaration of Independence; this draft of the document did not surface unti
Aquaculture known as aquafarming, is the farming of fish, molluscs, aquatic plants and other organisms. Aquaculture involves cultivating freshwater and saltwater populations under controlled conditions, can be contrasted with commercial fishing, the harvesting of wild fish. Mariculture refers to aquaculture practiced in underwater habitats. According to the Food and Agriculture Organization, aquaculture "is understood to mean the farming of aquatic organisms including fish, molluscs and aquatic plants. Farming implies some form of intervention in the rearing process to enhance production, such as regular stocking, protection from predators, etc. Farming implies individual or corporate ownership of the stock being cultivated." The reported output from global aquaculture operations in 2014 supplied over one half of the fish and shellfish, directly consumed by humans. Further, in current aquaculture practice, products from several pounds of wild fish are used to produce one pound of a piscivorous fish like salmon.
Particular kinds of aquaculture include fish farming, shrimp farming, oyster farming, mariculture and the cultivation of ornamental fish. Particular methods include aquaponics and integrated multi-trophic aquaculture, both of which integrate fish farming and aquatic plant farming; the indigenous Gunditjmara people in Victoria, may have raised eels as early as 6000 BC. Evidence indicates they developed about 100 km2 of volcanic floodplains in the vicinity of Lake Condah into a complex of channels and dams, used woven traps to capture eels, preserve them to eat all year round. Aquaculture was operating in China circa 2000 BC; when the waters subsided after river floods, some fish carp, were trapped in lakes. Early aquaculturists fed their brood using nymphs and silkworm feces, ate them. A fortunate genetic mutation of carp led to the emergence of goldfish during the Tang dynasty. However, ancient Egyptians might have farmed fish from Lake Bardawil about 3,500 years ago, they traded them with Canaan.
Gim cultivation is the oldest aquaculture in Korea. Early cultivation methods used bamboo or oak sticks, which were replaced by newer methods that utilized nets in the 19th century. Floating rafts have been used for mass production since the 1920s. Japanese cultivated seaweed by providing bamboo poles and nets and oyster shells to serve as anchoring surfaces for spores. Romans bred fish in ponds and farmed oysters in coastal lagoons before 100 CE. In central Europe, early Christian monasteries adopted Roman aquacultural practices. Aquaculture spread in Europe during the Middle Ages since away from the seacoasts and the big rivers, fish had to be salted so they did not rot. Improvements in transportation during the 19th century made fresh fish available and inexpensive in inland areas, making aquaculture less popular; the 15th-century fishponds of the Trebon Basin in the Czech Republic are maintained as a UNESCO World Heritage Site. Hawaiians constructed oceanic fish ponds. A remarkable example is the "Menehune" fishpond dating from at least 1,000 years ago, at Alekoko.
Legend says. In the first half of the 18th century, German Stephan Ludwig Jacobi experimented with external fertilization of brown trouts and salmon, he wrote an article "Von der künstlichen Erzeugung der Forellen und Lachse". By the latter decades of the 18th century, oyster farming had begun in estuaries along the Atlantic Coast of North America; the word aquaculture appeared in an 1855 newspaper article in reference to the harvesting of ice. It appeared in descriptions of the terrestrial agricultural practise of subirrigation in the late 19th century before becoming associated with the cultivation of aquatic plant and animal species. In 1859, Stephen Ainsworth of West Bloomfield, New York, began experiments with brook trout. By 1864, Seth Green had established a commercial fish-hatching operation at Caledonia Springs, near Rochester, New York. By 1866, with the involvement of Dr. W. W. Fletcher of Concord, artificial fish hatcheries were under way in both Canada and the United States; when the Dildo Island fish hatchery opened in Newfoundland in 1889, it was the largest and most advanced in the world.
The word aquaculture was used in descriptions of the hatcheries experiments with cod and lobster in 1890. By the 1920s, the American Fish Culture Company of Carolina, Rhode Island, founded in the 1870s was one of the leading producers of trout. During the 1940s, they had perfected the method of manipulating the day and night cycle of fish so that they could be artificially spawned year around. Californians harvested wild kelp and attempted to manage supply around 1900 labeling it a wartime resource. Harvest stagnation in wild fisheries and overexploitation of popular marine species, combined with a growing demand for high-quality protein, encouraged aquaculturists to domesticate other marine species. At the outset of modern aquaculture, many were optimistic that a "Blue Revolution" could take place in aquaculture, just as the Green Revolution of the 20th century had revolutionized agriculture. Although land animals had long been domesticated, most seafood species were still caught from the wild.
Concerned about the impact of growing demand for seafood on the world's oceans, prominent ocean explorer Jacques Cousteau wrote in 1973: "With earth's burgeoning human populations to feed, we must turn to the sea with new understanding and new technology."About 430 of the species cultu
Cattle—colloquially cows—are the most common type of large domesticated ungulates. They are a prominent modern member of the subfamily Bovinae, are the most widespread species of the genus Bos, are most classified collectively as Bos taurus. Cattle are raised as livestock for meat, for milk, for hides, which are used to make leather, they are used as riding animals and draft animals. Another product of cattle is dung, which can be used to create fuel. In some regions, such as parts of India, cattle have significant religious meaning. Cattle small breeds such as the Miniature Zebu, are kept as pets. Around 10,500 years ago, cattle were domesticated from as few as 80 progenitors in central Anatolia, the Levant and Western Iran. According to an estimate from 2011, there are 1.4 billion cattle in the world. In 2009, cattle became one of the first livestock animals to have a mapped genome; some consider cattle the oldest form of wealth, cattle raiding one of the earliest forms of theft. Cattle were identified as three separate species: Bos taurus, the European or "taurine" cattle.
The aurochs is ancestral to both taurine cattle. These have been reclassified as one species, Bos taurus, with three subspecies: Bos taurus primigenius, Bos taurus indicus, Bos taurus taurus. Complicating the matter is the ability of cattle to interbreed with other related species. Hybrid individuals and breeds exist, not only between taurine cattle and zebu, but between one or both of these and some other members of the genus Bos – yaks and gaur. Hybrids such as the beefalo breed can occur between taurine cattle and either species of bison, leading some authors to consider them part of the genus Bos, as well; the hybrid origin of some types may not be obvious – for example, genetic testing of the Dwarf Lulu breed, the only taurine-type cattle in Nepal, found them to be a mix of taurine cattle and yak. However, cattle cannot be hybridized with more distantly related bovines such as water buffalo or African buffalo; the aurochs ranged throughout Europe, North Africa, much of Asia. In historical times, its range became restricted to Europe, the last known individual died in Mazovia, Poland, in about 1627.
Breeders have attempted to recreate cattle of similar appearance to aurochs by crossing traditional types of domesticated cattle, creating the Heck cattle breed. The noun cattle encompasses both sexes; the singular, technically means the female, the male being bull. The plural form cows is sometimes used colloquially to refer to both sexes collectively, as e.g. in a herd, but that usage can be misleading as the speaker's intent may indeed be just the females. The bovine species per se is dimorphic. Cattle did not originate as the term for bovine animals, it was borrowed from Anglo-Norman catel, itself from medieval Latin capitale'principal sum of money, capital', itself derived in turn from Latin caput'head'. Cattle meant movable personal property livestock of any kind, as opposed to real property; the word is a variant of chattel and related to capital in the economic sense. The term replaced earlier Old English feoh ` property', which survives today as fee; the word "cow" came via Anglo-Saxon cū, from Common Indo-European gʷōus = "a bovine animal", compare Persian: gâv, Sanskrit: go-, Welsh: buwch.
The plural cȳ became ki or kie in Middle English, an additional plural ending was added, giving kine, but kies and others. This is the origin of the now archaic English plural, "kine"; the Scots language singular is coo or cou, the plural is "kye". In older English sources such as the King James Version of the Bible, "cattle" refers to livestock, as opposed to "deer" which refers to wildlife. "Wild cattle" may refer to undomesticated species of the genus Bos. Today, when used without any other qualifier, the modern meaning of "cattle" is restricted to domesticated bovines. In general, the same words are used in different parts of the world, but with minor differences in the definitions; the terminology described here contrasts the differences in definition between the United Kingdom and other British-influenced parts of the world such as Canada, New Zealand and the United States. An "intact" adult male is called a bull. A wild, unmarked bull is known as a micky in Australia. An unbranded bovine of either sex is called a maverick in the Canada.
An adult female that has had a calf is a cow. A young female before she has had a calf of her own and is under three years of age is called a heifer. A young female that has had only one calf is called a first-calf heifer. Young cattle of both sexes are called calves until they are weaned weaners until they are a year old in some areas. After that, they are referred to as stirks if between one and two years of age. A castrated male is called a steer in the United States.
