Anadara Broughtonii
Anadara broughtonii is a species of Ark clam. The species was described by Shrenck in 1867. Originally belonging to the genus '' Scapharca'', the genus has merged with ''Anadara'' now. Adult blood clams can reach a shell length of 100 mm and are commercially harvested in China, Japan, and Korea as a source of sashimi. To develop both the scientific research and improve the aquaculture of blood clams, a chromosomal-level genome assembly of the ''S. broughtonii'' genome has been sequenced and assembled, producing a 884.5-Mb genome. Distribution The species is distributed in Far East, from Russia down to Korea, Mainland China, Japan and Taiwan Taiwan, officially the Republic of China (ROC), is a country in East Asia, at the junction of the East and South China Seas in the northwestern Pacific Ocean, with the People's Republic of China (PRC) to the northwest, Japan to the northe ....

Ark Clam
Ark clam is the common name for a family of small to large-sized saltwater clams or marine bivalve molluscs in the family Arcidae. Ark clams vary both in shape and size. They number about 200 species worldwide. The shells of ark clams are often white or cream, but in some species, the shell is striped with, tinted with, or completely colored, a rich brown. In life the shell of most species has a top shell layer that is thick brown periostracum affixed to the harder calcareous part of the shell. In some species such as ''Barbatia'', this outer horny covering is tufted at the end of the shell into something that resembles a beard, hence the name ''Barbatia'' or bearded one. The group is known as "ark shells" because species such as '' Arca'' have a large flat area between the umbones which, in an undamaged shell, somewhat resembles a deck, with the rest of the shell perhaps illustrating an ancient wooden boat such as Noah's ark is thought to have been. All ark shells have a lo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Scapharca
''Anadara'' is a genus of saltwater bivalves, ark clams, in the family Arcidae. It is also called ''Scapharca''. This genus is known in the fossil record from the Cretaceous period to the Quaternary period (age range: 140.2 to 0.0 million years ago). These fossils have been found all over the world. Species The following species are recognised in the genus ''Anadara'': * '' Anadara adamsi'' * ''Anadara aequatorialis'' * ''Anadara aethiopica'' * ''Anadara aliena'' * ''Anadara ambigua'' * ''Anadara amicula'' * ''Anadara angicostata'' * ''Anadara antiquata'' (Linnaeus, 1758) * ''Anadara auriculata'' Lamarck * ''Anadara axelolssoni'' * ''Anadara bataviensis'' * ''Anadara biangulata'' * ''Anadara bifrons'' * ''Anadara bonplandiana'' * ''Anadara brasiliana'' (Lamarck, 1819) - incongruous ark * ''Anadara broughtonii'' ( Schrenck, 1867) * ''Anadara camerunensis'' * ''Anadara cepoides'' * ''Anadara chemnitzii'' (Philippi, 1851) - Chemnitz ark, triangular ark * '' ...

Aquaculture
Aquaculture (less commonly spelled aquiculture), also known as aquafarming, is the controlled cultivation ("farming") of aquatic organisms such as fish, crustaceans, mollusks, algae and other organisms of value such as aquatic plants (e.g. lotus). Aquaculture involves cultivating freshwater, brackish water and saltwater populations under controlled or semi-natural conditions, and can be contrasted with commercial fishing, which is the harvesting of wild fish. Mariculture, commonly known as marine farming, refers specifically to aquaculture practiced in seawater habitats and lagoons, opposed to in freshwater aquaculture. Pisciculture is a type of aquaculture that consists of fish farming to obtain fish products as food. Aquaculture can also be defined as the breeding, growing, and harvesting of fish and other aquatic plants, also known as farming in water. It is an environmental source of food and commercial product which help to improve healthier habitats and used to reco ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Far East
The ''Far East'' was a European term to refer to the geographical regions that includes East and Southeast Asia as well as the Russian Far East to a lesser extent. South Asia is sometimes also included for economic and cultural reasons. The term first came into use in European geopolitical discourse in the 15th century, particularly the British, denoting the Far East as the "farthest" of the three "Easts", beyond the Near East and the Middle East. Likewise, during the Qing dynasty of the 19th and early 20th centuries, the term " Tàixī ()" – i.e., anything further west than the Arab world – was used to refer to the Western countries. Since the mid-20th century, the term has mostly gone out of use for the region in international mass media outlets due to its eurocentric connotations.Reischauer, Edwin and John K Fairbank, ''East Asia: The Great Tradition,'' 1960. The Russian Far East is often excluded due to cultural and ethnic differences, and is often considered as part ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Korea
Korea ( ko, 한국, or , ) is a peninsular region in East Asia. Since 1945, it has been divided at or near the 38th parallel, with North Korea (Democratic People's Republic of Korea) comprising its northern half and South Korea (Republic of Korea) comprising its southern half. Korea consists of the Korean Peninsula, Jeju Island, and several minor islands near the peninsula. The peninsula is bordered by China to the northwest and Russia to the northeast. It is separated from Japan to the east by the Korea Strait and the Sea of Japan (East Sea). During the first half of the 1st millennium, Korea was divided between three states, Goguryeo, Baekje, and Silla, together known as the Three Kingdoms of Korea. In the second half of the 1st millennium, Silla defeated and conquered Baekje and Goguryeo, leading to the " Unified Silla" period. Meanwhile, Balhae formed in the north, superseding former Goguryeo. Unified Silla eventually collapsed into three separate states due ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
