Aquaculture In China
China, with one-fifth of the world's population, accounts for two-thirds of the world's reported aquaculture production.FAO Fact sheetAquaculture in China and Asia/ref> Aquaculture is the farming of fish and other aquatic life in enclosures, such as ponds, lakes and tanks, or cages in rivers and coastal waters. China's 2005 reported harvest was 32.4 million tonnes, more than 10 times that of the second-ranked nation, India, which reported 2.8 million tonnes. China's 2005 reported catch of wild fish, caught in rivers, lakes, and the sea, was 17.1 million tonnes. This means that aquaculture accounts for nearly two-thirds of China's reported total output. The principal aquaculture-producing regions are close to urban markets in the middle and lower Yangtze valley and the Zhu Jiang delta. Early history Aquaculture began about 3500 BC in China with the farming of the common carp. These carp were grown in ponds on silk farms, and were fed silkworm nymphs and faeces.Parker R (2000''Aq ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mariculture
Mariculture or marine farming is a specialized branch of aquaculture (which includes freshwater aquaculture) involving the cultivation of marine organisms for food and other animal products, in enclosed sections of the open ocean ( offshore mariculture), fish farms built on littoral waters ( inshore mariculture), or in artificial tanks, ponds or raceways which are filled with seawater ( onshore mariculture). An example of the latter is the farming of marine fish, including finfish and shellfish like prawns, or oysters and seaweed in saltwater ponds. Non-food products produced by mariculture include: fish meal, nutrient agar, jewellery (e.g. cultured pearls), and cosmetics. Methods Algae Shellfish Similar to algae cultivation, shellfish can be farmed in multiple ways: on ropes, in bags or cages, or directly on (or within) the intertidal substrate. Shellfish mariculture does not require feed or fertilizer inputs, nor insecticides or antibiotics, making shellfish aquacult ...

Tang Dynasty
The Tang dynasty (, ; zh, t= ), or Tang Empire, was an Dynasties in Chinese history, imperial dynasty of China that ruled from 618 to 907 AD, with an Zhou dynasty (690–705), interregnum between 690 and 705. It was preceded by the Sui dynasty and followed by the Five Dynasties and Ten Kingdoms period. Historians generally regard the Tang as a high point in Chinese civilization, and a Golden age (metaphor), golden age of cosmopolitan culture. Tang territory, acquired through the military campaigns of its early rulers, rivaled that of the Han dynasty. The House of Li, Lǐ family () founded the dynasty, seizing power during the decline and collapse of the Sui Empire and inaugurating a period of progress and stability in the first half of the dynasty's rule. The dynasty was formally interrupted during 690–705 when Empress Wu Zetian seized the throne, proclaiming the Zhou dynasty (690–705), Wu Zhou dynasty and becoming the only legitimate Chinese empress regnant.

Black Carp
The black carp (''Mylopharyngodon piceus'') or Chinese black roach is a species of cyprinid freshwater fish and the sole extant species of the genus ''Mylopharyngodon''. It is native to lakes and rivers in East Asia, ranging from the Amur Basin across China to Vietnam. One of the largest cyprinids in the world, the black carp has a typical length of , though it can reach up to in length and in weight. It is carnivorous and generally feeds on invertebrates such as snails, clams and mussels. Black carp, together with bighead carp, silver carp, and grass carp, make up the culturally important " four famous domestic fishes" used in polyculture in China for over a thousand years. It has also been introduced in the United States as one of the invasive " Asian carps", though it is not as widely distributed worldwide as the other three. In China, black carp is widely cultivated for food and Chinese medicine, being one of the most highly esteemed and expensive domestic food fish, a ...

Live Fish Trade
The live fish trade can refer to the live food fish trade (for human consumption) or to the ornamental fish trade (for aquariums). The fish can come from many places, but most comes from Southeast Asia. The live food fish trade is a global system that links fishing communities with markets, primarily in Hong Kong and mainland China. Many of the fish are captured on coral reefs in Southeast Asia or the Pacific Island nations. Consumer demand Within the live food trade there are certain types of fish demanded more often by consumers, particularly smaller and medium-sized fish. According to the book While Stocks Last: The Live Reef Food Fish Trade consumer demand has caused the fish captured on coral reefs to be the most valued fish in the trade. Consumers are important because they are directly purchasing these fish species at restaurants and stores. In addition to these types of fishes, many juvenile fish are used for the live food trade. There are also cultural and regiona ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ming Dynasty
The Ming dynasty (), officially the Great Ming, was an Dynasties in Chinese history, imperial dynasty of China, ruling from 1368 to 1644 following the collapse of the Mongol Empire, Mongol-led Yuan dynasty. The Ming dynasty was the last orthodox dynasty of China ruled by the Han Chinese, Han people, the majority ethnic group in China. Although the primary capital of Beijing fell in 1644 to a rebellion led by Li Zicheng (who established the short-lived Shun dynasty), numerous rump state, rump regimes ruled by remnants of the House of Zhu, Ming imperial family—collectively called the Southern Ming—survived until 1662. The Ming dynasty's founder, the Hongwu Emperor (r. 1368–1398), attempted to create a society of self-sufficient rural communities ordered in a rigid, immobile system that would guarantee and support a permanent class of soldiers for his dynasty: the empire's standing army exceeded one million troops and the naval history of China, navy's dockyards in Nanjin ...

Goldfish
The goldfish (''Carassius auratus'') is a freshwater fish in the family Cyprinidae of order Cypriniformes. It is commonly kept as a pet in indoor aquariums, and is one of the most popular aquarium fish. Goldfish released into the wild have become an invasive pest in parts of North America. Native to East Asia, the goldfish is a relatively small member of the carp family (which also includes the Prussian carp and the crucian carp). It was first selectively bred for color in imperial China more than 1,000 years ago, and several distinct breeds have since been developed. Goldfish breeds vary greatly in size, body shape, fin configuration, and coloration (various combinations of white, yellow, orange, red, brown, and black are known). History Various species of carp (collectively known as Asian carp) have been bred and reared as food fish for thousands of years in East Asia. Some of these normally gray or silver species have a tendency to produce red, orange or yellow ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Bighead Carp
The bighead carp (''Hypophthalmichthys nobilis'') is a species of cyprinid freshwater fish native to East Asia, and is one of several Asian carps introduced into North America. It is one of the most intensively exploited fishes in fish farming, with an annual worldwide production of over three million tonnes in 2013, principally from China. Unlike the omnivorous common carp, bighead carp are primarily filter-feeders, preferentially consuming zooplankton but also phytoplankton and detritus. Description The bighead carp has a large, scaleless head, a large mouth, and eyes located very low on the head. Adults usually have a mottled silver-gray coloration. It is a large fish; a typical length is , and maximum observed size of and . Distribution Bighead carp are native to large rivers and are associated with floodplain lakes of eastern Asia. Their range extends from southern China north to the Amur River system, which forms the border between China and Russia. They have been i ...

Silver Carp
The silver carp (''Hypophthalmichthys molitrix'') is a species of freshwater cyprinid fish, a variety of Asian carp native to China and eastern Siberia, from the Amur River drainage in the north to the Xi Jiang River drainage in the south. Although a threatened species in its natural habitat, it has long been cultivated in China. By weight, more silver carp are produced worldwide in aquaculture than any other species of fish except for the grass carp. Silver carp are usually farmed in polyculture with other Asian carp, or sometimes with catla or other fish species. The species has also been introduced, or spread by connected waterways, to at least 88 countries around the world. The reason for importation was generally for use in aquaculture, but enhancement of wild fisheries and water quality control have also been intended on occasion. In some of these places, the species is considered invasive. The silver carp reaches a typical length of with a maximum length of and ...

Bottom Feeder
A bottom feeder is an aquatic animal that feeds on or near the bottom of a body of water. Biologists often use the terms ''benthos''—particularly for invertebrates such as shellfish, crabs, crayfish, sea anemones, starfish, snails, bristleworms and sea cucumbers—and ''benthivore'' or ''benthivorous'', for fish and invertebrates that feed on material from the bottom. However the term benthos includes all aquatic life that lives on or near the bottom, which means it also includes non-animals, such as plants and algae. Biologists also use specific terms that refer to bottom feeding fish, such as demersal fish, groundfish, benthic fish and benthopelagic fish. Examples of bottom feeding fish species groups are flatfish (halibut, flounder, plaice, sole), eels, cod, haddock, bass, grouper, carp, bream ( snapper) and some species of catfish and shark. Feeding strategies Some bottom feeders are detritivores taking advantage of organic materials that sink down through ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
