Fisheries Science
Fisheries science is the academic discipline of managing and understanding fisheries. It is a multidisciplinary science, which draws on the disciplines of limnology, oceanography, freshwater biology, marine biology, meteorology, conservation, ecology, population dynamics, economics, statistics, decision analysis, management, and many others in an attempt to provide an integrated picture of fisheries. In some cases new disciplines have emerged, as in the case of bioeconomics and fisheries law. Because fisheries science is such an all-encompassing field, fisheries scientists often use methods from a broad array of academic disciplines. Over the most recent several decades, there have been declines in fish stocks (populations) in many regions along with increasing concern about the impact of intensive fishing on marine and freshwater biodiversity. Fisheries science is typically taught in a university setting, and can be the focus of an undergraduate, master's or Ph.D. program. Some ...

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 ...

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] |
Fishing Industry In China
China has one-fifth of the world's population and accounts for one-third of the world's reported fish production as well as two-thirds of the world's reported aquaculture production.FAO Fact sheetAquaculture in China and Asia It is also a major importer of seafood and the country's seafood market is estimated to grow to a market size worth US$53.5 Billion by 2027. China's 2005 reported catch of wild fish, caught in rivers, lakes, and the sea, was 17.1 million tonnes, far ahead of the second-ranked nation, the United States, which reported 4.9 million tonnes. The Chinese commercial fishing fleet is responsible for more illegal, unreported and unregulated fishing than that of any other nation. Aquaculture, the farming of fish in ponds, lakes and tanks, accounts for two-thirds of China's reported output. 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. The country's aquaculture marke ...

Chinese Sturgeon
The Chinese sturgeon (''Acipenser sinensis''; ) is a critically endangered member of the family Acipenseridae in the order Acipenseriformes. Historically, this anadromous fish was found in China, Japan, and the Korean Peninsula, but it has been extirpated from most regions due to habitat loss and overfishing. It is strictly protected by the Chinese government, named a "national treasure" much like its mammalian counterpart, the giant panda. China has several conservation programmes, including reserves specifically aimed at this species and restocking through release of juveniles in the Yangtze River. Physical appearance Sturgeon are comparatively basal species of fish, whose earliest fossils date back to the Cretaceous period. They are best-known members of the bony fish taxon Chondrostei, a group of bony fishes that have cartilaginous skeletons superficially similar to the skeletons seen in the unrelated chondrichthyan fishes. In Qing dynasty Chinese cuisine, its mea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Feed Conversion Rate
In animal husbandry, feed conversion ratio (FCR) or feed conversion rate is a ratio or rate measuring of the efficiency with which the bodies of livestock convert animal feed into the desired output. For dairy cows, for example, the output is milk, whereas in animals raised for meat (such as beef cows,Dan Shike, University of IllinoiBeef Cattle Feed Efficiency/ref> pigs, chickens, and fish) the output is the flesh, that is, the body mass gained by the animal, represented either in the final mass of the animal or the mass of the dressed output. FCR is the mass of the input divided by the output (thus mass of feed per mass of milk or meat). In some sectors, feed efficiency, which is the output divided by the input (i.e. the inverse of FCR), is used. These concepts are also closely related to efficiency of conversion of ingested foods (ECI). Background Feed conversion ratio (FCR) is the ratio of inputs to outputs; it is the inverse of "feed efficiency" which is the ratio of o ...
