Trần Đắc Định
Trần (陳) or Tran is a common Vietnamese surname. More than 10% of all Vietnamese people share this surname. It is derived from the common Chinese surname Chen. History The Tran ruled the Trần dynasty, a golden era in Vietnam, and successfully withheld the Mongol invasions of Vietnam, introducing improvements to Chinese gunpowder. During the Tran dynasty, arts and sciences flourished, and Chữ Nôm was used for the first time in mainstream poetry. Emperor Trần Nhân Tông was a great reformer of Chu Nom and the first emperor to use Chu Nom in Vietnamese poetry.

Phallostethidae
Phallostethidae, also known as the priapium fish, is a family of atheriniform fish native to freshwater and brackish habitats in southeast Asia. They are small, no more than in length, with partially translucent bodies. They are found in fresh and brackish water from Thailand to the Philippines and Sulawesi. They are named for a muscular organ found under the chin of males. This organ, which may possess small testicles, is used together with the pelvic fins to grasp the female during mating. Unlike most other fish, priapium fishes exhibit internal fertilisation, although they are oviparous. Subdivision The family Phallostethidae is divided into two subfamilies and four genera: * Subfamily Phallostethinae Regan, 1916 ** Genus '' Neostethus'' Regan, 1916 ** Genus '' Phallostethus'' Regan, 1916 ** Genus '' Phenacostethus'' Myers, 1928 * Subfamily Gulaphallinae ''Gulaphallus'' is a genus of fishes in the family Phallostethidae, native to the Philippines.

Mekong Delta
The Mekong Delta ( vi, Đồng bằng Sông Cửu Long, lit=Nine Dragon River Delta or simply vi, Đồng Bằng Sông Mê Kông, lit=Mekong River Delta, label=none), also known as the Western Region ( vi, Miền Tây, links=no) or South-western region ( vi, Tây Nam Bộ, links=no), is the region in southwestern Vietnam where the Mekong River approaches and empties into the sea through a network of distributaries. The Mekong delta region encompasses a large portion of south-western Vietnam of over . The size of the area covered by water depends on the season. Its wet coastal geography makes it an important source of agriculture and aquaculture for the country. The delta has been occupied as early as the 4th century BC. As a product of Khmer, Vietnamese, Chinese, and French settlement in the region, the delta and its waterways have numerous names, including the Khmer term Bassac to refer to the lower basin and the largest river branch flowing through it.

Fish Measurement
Fish measurement is the measuring of individual fish and various parts of their anatomies. These data are used in many areas of ichthyology, including taxonomy and fisheries biology. Overall length * Standard length (SL) is the length of a fish measured from the tip of the snout to the posterior end of the last vertebra or to the posterior end of the midlateral portion of the hypural plate. Simply put, this measurement excludes the length of the caudal (tail) fin. * Total length (TL) is the length of a fish measured from the tip of the snout to the tip of the longer lobe of the caudal fin, usually measured with the lobes compressed along the midline. It is a straight-line measure, not measured over the curve of the body. Standard length measurements are used with Teleostei (most bony fish), while total length measurements are used with Myxini ( hagfish), Petromyzontiformes ( lampreys), and (usually) Elasmobranchii (shark Sharks are a group of elasmobranch fish chara ...

Mekong
The Mekong or Mekong River is a trans-boundary river in East Asia and Southeast Asia. It is the world's twelfth longest river and the third longest in Asia. Its estimated length is , and it drains an area of , discharging of water annually. From the Tibetan Plateau the river runs through China, Myanmar, Laos, Thailand, Cambodia, and Vietnam. The extreme seasonal variations in flow and the presence of rapids and waterfalls in the Mekong make navigation difficult. Even so, the river is a major trade route between western China and Southeast Asia. Names The Mekong was originally called ''Mae Nam Khong'' from a contracted form of Tai shortened to ''Mae Khong''. In Thai and Lao, ''Mae Nam'' ("Mother of Water ) is used for large rivers and ''Khong'' is the proper name referred to as "River Khong". However, ''Khong'' is an archaic word meaning "river", loaned from Austroasiatic languages, such as Vietnamese ''sông'' (from *''krong'') and Mon ''kruŋ'' "river", which led to Chine ...

2012 In Vietnam
1 (one, unit, unity) is a number representing a single or the only entity. 1 is also a numerical digit and represents a single unit of counting or measurement. For example, a line segment of ''unit length'' is a line segment of length 1. In conventions of sign where zero is considered neither positive nor negative, 1 is the first and smallest positive integer. It is also sometimes considered the first of the infinite sequence of natural numbers, followed by 2, although by other definitions 1 is the second natural number, following 0. The fundamental mathematical property of 1 is to be a multiplicative identity, meaning that any number multiplied by 1 equals the same number. Most if not all properties of 1 can be deduced from this. In advanced mathematics, a multiplicative identity is often denoted 1, even if it is not a number. 1 is by convention not considered a prime number; this was not universally accepted until the mid-20th century. Additionally, 1 is the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fish Described In 2012
Fish are aquatic, craniate, gill-bearing animals that lack limbs with digits. Included in this definition are the living hagfish, lampreys, and cartilaginous and bony fish as well as various extinct related groups. Approximately 95% of living fish species are ray-finned fish, belonging to the class Actinopterygii, with around 99% of those being teleosts. The earliest organisms that can be classified as fish were soft-bodied chordates that first appeared during the Cambrian period. Although they lacked a true spine, they possessed notochords which allowed them to be more agile than their invertebrate counterparts. Fish would continue to evolve through the Paleozoic era, diversifying into a wide variety of forms. Many fish of the Paleozoic developed external armor that protected them from predators. The first fish with jaws appeared in the Silurian period, after which many (such as sharks) became formidable marine predators rather than just the prey of arthropods. Most fis ...
