Pethia Didi
''Pethia didi'' is a species of cyprinid fish which has only been recorded in the vicinity of Myitkyina and Indawgyi Lake in the north of Myanmar. This is a small fish which can reach a length of fish measurement, SL. It is generally brownish with a dark vertical bar just behind the Operculum (fish), operculum and a round dark blotch on the Fish anatomy, caudal peduncle. The species ''Pethia tiantian, P. tiantian'' – with a range close to ''P. didi'' – is similarly marked, but ''P. didi'' can be distinguished by its truncated lateral line, deeper body and longer dorsal fin, with two rows of dark markings rather than one.

Sven O
Sven (in Danish and Norwegian, also Svend and also in Norwegian most commonly Svein) is a Scandinavian first name which is also used in the Low Countries and German-speaking countries. The name itself is Old Norse for "young man" or "young warrior". The original spelling in Old Norse was ''sveinn''. Over the centuries, many northern European rulers have carried the name including Sweyn I of Denmark (Sven Gabelbart). An old legend relates the pagan king Blot-Sven ordered the execution of the Anglo-Saxon monk Saint Eskil. In medieval Swedish, "sven" (or "sven av vapen" (sven of arms)) is a term for squire. The female equivalent, Svenja, though seemingly Dutch and Scandinavian, is not common anywhere outside of German-speaking countries. Sven can also be spelled with W, Swen, but is pronounced as Sven. The Icelandic version of Sven/Svend is Sveinn (); the Faroese version is Sveinur (). Entertainment and music * Sven Einar Englund, Finnish composer * Sven Epiney, Swiss televis ...

Fang Fang Kullander
Fang Fang Kullander, ''née'' Fang Fang, (14 November 1962 – 19 May 2010) was a Swedish-Chinese ichthyologist. Early life Fang Fang was born on 14 November 1962 in Beijing, her parents were Fang Zongxian and Hang Mingxhien, both geologists. Fang Fang attended primary school in Beijing from 1969 but the family was forced to move to Sanmenxia in Henan and then to Fenghua in Zhejiang, her father's home town, during the Cultural Revolution when her parents' institute was compelled to move out of the capital. She excelled at languages and at writing, her talent for the latter emerging at middle school in Sanmexia. Education Fang Fang entered the Zhanjiang Fisheries College in Guangdong in 1980 where she majored in the study of freshwater fish, graduating in 1984 with her Bachelor's thesis being about the anatomy of the catfish '' Clarias lazera''. This thesis was awarded the second prize of the Scientific and Technological Advancement by the Chinese Agriculture ministry in 1986. She ...

Species
In biology, a species is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology, behaviour or ecological niche. In addition, paleontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. However, only about 14% of these had been described by 2011. All species (except viruses) are given a two-part name, a "binomial". The first part of a binomial is the genus to which the species belongs. The second part is called the specific name or the specific epithet (in botanical nomenclature, also sometimes i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cyprinid
Cyprinidae is a family of freshwater fish commonly called the carp or minnow family. It includes the carps, the true minnows, and relatives like the barbs and barbels. Cyprinidae is the largest and most diverse fish family and the largest vertebrate animal family in general with about 3,000 species, of which only 1,270 remain extant, divided into about 370 genera. Cyprinids range from about 12 mm in size to the giant barb (''Catlocarpio siamensis''). By genus and species count, the family makes up more than two-thirds of the ostariophysian order Cypriniformes. The family name is derived from the Greek word ( 'carp'). Biology and ecology Cyprinids are stomachless fish with toothless jaws. Even so, food can be effectively chewed by the gill rakers of the specialized last gill bow. These pharyngeal teeth allow the fish to make chewing motions against a chewing plate formed by a bony process of the skull. The pharyngeal teeth are unique to each species and are used by scient ...

Myitkyina
Myitkyina (, ; (Eng; ''mitchinar'') Jinghpaw: ''Myitkyina'', ) is the capital city of Kachin State in Myanmar (Burma), located from Yangon, and from Mandalay. In Burmese it means "near the big river", and Myitkyina is on the west bank of the Ayeyarwady River, just below from Myit-son (Burmese for confluence) of its two headstreams (the Mali and N'mai rivers). It is the northernmost river port and railway terminus in Myanmar. The city is served by Myitkyina Airport. History Myitkyina has been an important trading town between China and Myanmar since ancient times. American Baptist missionary George J. Geis and his wife arrived in Myitkyina in the late 1890s and in 1900 they requested permission to build a mansion in the town. The building was named Geis Memorial Church. It is one of the Kachin Baptist Convention (KBC) churches in Myitkyina. Japanese forces captured the town and nearby airbase during World War II in 1942. In August 1944, Myitkyina was recaptured by the A ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Indawgyi Lake
Indawgyi Lake ( ) is one of the largest inland lakes in Southeast Asia. It is located in Mohnyin Township in the Kachin State of Myanmar. The lake measures east to west, and north to south. There are over 20 villages around the lake. The predominant ethnic groups living in the surroundings of the lake are the Shan and the Kachin, who mainly practise agriculture. It is above sea level.http://www.mrtv3.net.mm/newpaper/209newsn.pdf Page 11 Column 2 The lake is the main feature of the Indawgyi Lake Wildlife Sanctuary. It has a length of , width of seven miles and an area of . There are 11 village-tracts, 36 villages around the lake; 13 villages are on the bank of the lake.

Myanmar
Myanmar, ; UK pronunciations: US pronunciations incl. . Note: Wikipedia's IPA conventions require indicating /r/ even in British English although only some British English speakers pronounce r at the end of syllables. As John C. Wells, John Wells explains, the English spellings of both Myanmar and Burma assume a non-rhotic variety of English, in which the letter r before a consonant or finally serves merely to indicate a long vowel: [ˈmjænmɑː, ˈbɜːmə]. So the pronunciation of the last syllable of Myanmar as [mɑːr] or of Burma as [bɜːrmə] by some speakers in the UK and most speakers in North America is in fact a spelling pronunciation based on a misunderstanding of non-rhotic spelling conventions. The final ''r'' in ''Myanmar'' was not intended for pronunciation and is there to ensure that the final a is pronounced with the broad a, broad ''ah'' () in "father". If the Burmese name my, မြန်မာ, label=none were spelled "Myanma" in English, this would b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 (sharks and rays), as well as some other fishes. Total length meas ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Operculum (fish)
The operculum is a series of bones found in bony fish and chimaeras that serves as a facial support structure and a protective covering for the gills; it is also used for respiration and feeding. Anatomy The opercular series contains four bone segments known as the preoperculum, suboperculum, interoperculum and operculum. The preoperculum is a crescent-shaped structure that has a series of ridges directed posterodorsally to the organisms canal pores. The preoperculum can be located through an exposed condyle that is present immediately under its ventral margin; it also borders the operculum, suboperculum, and interoperculum posteriorly. The suboperculum is rectangular in shape in most bony fishy and is located ventral to the preoperculum and operculum components. It is the thinnest bone segment out of the opercular series and is located directly above the gills. The interoperculum is triangular shaped and borders the suboperculum posterodorsally and the preoperculum anterodorsa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fish Anatomy
Fish anatomy is the study of the form or morphology of fish. It can be contrasted with fish physiology, which is the study of how the component parts of fish function together in the living fish. In practice, fish anatomy and fish physiology complement each other, the former dealing with the structure of a fish, its organs or component parts and how they are put together, such as might be observed on the dissecting table or under the microscope, and the latter dealing with how those components function together in living fish. The anatomy of fish is often shaped by the physical characteristics of water, the medium in which fish live. Water is much denser than air, holds a relatively small amount of dissolved oxygen, and absorbs more light than air does. The body of a fish is divided into a head, trunk and tail, although the divisions between the three are not always externally visible. The skeleton, which forms the support structure inside the fish, is either made of cartilage ( ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pethia Tiantian
''Pethia tiantian'' is a species of cyprinid fish that has only been recorded from streams in the vicinity of Putao in the far north of Myanmar. It grows to a length of SL. It is generally brownish with a dark vertical bar just behind the operculum and a round dark blotch on the caudal peduncle. Other ''Pethia'' species are similarly marked but ''P. tiantian'' can be distinguished by its longer lateral line, reaching all the way back to the base of the caudal fin. '' P. didi'', a similarly marked species found in the same drainage basin, differs from ''P. tiantian'' in having a deeper body and a longer dorsal fin A dorsal fin is a fin located on the back of most marine and freshwater vertebrates within various taxa of the animal kingdom. Many species of animals possessing dorsal fins are not particularly closely related to each other, though through conv ... with two rows of dark markings rather than one.Kullander, S. O. & F.

Lateral Line
The lateral line, also called the lateral line organ (LLO), is a system of sensory organs found in fish, used to detect movement, vibration, and pressure gradients in the surrounding water. The sensory ability is achieved via modified epithelial cells, known as hair cells, which respond to displacement caused by motion and transduce these signals into electrical impulses via excitatory synapses. Lateral lines serve an important role in schooling behavior, predation, and orientation. Fish can use their lateral line system to follow the vortices produced by fleeing prey. Lateral lines are usually visible as faint lines of pores running lengthwise down each side, from the vicinity of the gill covers to the base of the tail. In some species, the receptive organs of the lateral line have been modified to function as electroreceptors, which are organs used to detect electrical impulses, and as such, these systems remain closely linked.
