Hanhowuz Reservoir
Hanhowuz, also known as Khauz-Khan, is a reservoir in Ahal Province of southeastern Turkmenistan. The M37 highway passes nearby and the village of Hanhowuz stands on the northwestern shore, with the city of Tejen not too far away in that direction. Hanhowuz Reservoir is a component of the Kara Kum Canal system and it was created to attempt to control the erratic Tejen River. It plays an important role in agriculture in the region. The reservoir is named after the legendary khan Oguz Han. Hanhowuz (Khauzkhan) Reservoir was constructed in a natural depression to capture winter runoff and overflow from the canal for use later during the driest periods of summer. Phytoplankton thrive in the warm waters, as do many commercial fish—including Aral barbel, asp and catfish. In the satellite image, Garagum Canal is the brown ribbon dropping down from the upper right corner and heading south and east from the reservoir. A portion of the canal is diverted, and can be seen the brow ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Oguz Han
Oghuz Khagan or Oghuz Khan ( tk, Oguz Han or Oguz Kagan ; tr, Oğuz Kağan or Oğuz Han; Azerbaijani: Oğuz Xan or Oğuz Xaqan) is a legendary khan of the Turkic people and an eponymous ancestor of Oghuz Turks. Some Turkic cultures use the legend of Oghuz Khan to describe their ethnic and tribal origins. The various versions of the narrative preserved in many different manuscripts has been published in numerous languages as listed below in the references. The narratives about him are often entitled Oghuzname, of which there are several traditions, describing his many feats and conquests, some of these tend to overlap with other Turkic epic traditions such as Seljukname and The Book of Dede Korkut. The name of Oghuz Khan has been associated with Maodun, also known as Mete Han; the reason being that there is a remarkable similarity between the biography of Oghuz Khagan in the Turkic mythology and the biography of Maodun found in the Chinese historiography, which was first notic ...

Garagum Canal
The Karakum Canal (Qaraqum Canal, Kara Kum Canal, Garagum Canal; russian: Каракумский канал, ''Karakumskiy Kanal'', tk, Garagum kanaly, , ) in Turkmenistan is one of the largest irrigation and water supply canals in the world. Started in 1954, and completed in 1988, it is navigable over much of its length, and carries of water annually from the Amu-Darya River across the Karakum Desert in Turkmenistan. The canal opened up huge new tracts of land to agriculture, especially to cotton monoculture heavily promoted by the Soviet Union, and supplying Ashgabat with a major source of water. The canal is also a major factor leading to the Aral Sea environmental disaster. The Soviet regime planned to at some time extend the canal to the Caspian Sea. History The current Karakum Canal was not the first major attempt to bring the Amu-Darya water to the Karakums. In the early 1950s, construction began on the Main Turkmen Canal (russian: Главный Туркменский ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Catfish
Catfish (or catfishes; order Siluriformes or Nematognathi) are a diverse group of ray-finned fish. Named for their prominent barbels, which resemble a cat's whiskers, catfish range in size and behavior from the three largest species alive, the Mekong giant catfish from Southeast Asia, the wels catfish of Eurasia, and the piraíba of South America, to detritivores (species that eat dead material on the bottom), and even to a tiny parasitic species commonly called the candiru, ''Vandellia cirrhosa''. Neither the armour-plated types nor the naked types have scales. Despite their name, not all catfish have prominent barbels or "whiskers". Members of the Siluriformes order are defined by features of the skull and swimbladder. Catfish are of considerable commercial importance; many of the larger species are farmed or fished for food. Many of the smaller species, particularly the genus ''Corydoras'', are important in the aquarium hobby. Many catfish are nocturnal, [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Asp (fish)
The asp (''Leuciscus aspius'') is a European freshwater fish of the Cyprinidae family. It is sometimes considered by taxonomic authorities to be one of two members of the genus ''Aspius''. It is protected under Appendix III of the Bern Convention and listed as least concern on the IUCN Red List. Normally, asps are between in length, with some reaching , and weighing up to . They inhabit lakes and lower reaches of rivers and estuaries. In April to June, asps migrate from lakes to streams for spawning. Spawning is triggered by the rise in temperature and usually starts at . The eggs attach to rocks, gravel, and water plants. After around two weeks, they hatch and the fry drift downstream to calmer waters. They tend to be active during the evening, when they may create large splashes as they hunt near the surface of the water. Asps can be found in Estonia, Lithuania, Latvia, Germany, Norway, Sweden, Finland, the Czech Republic, Poland, Ukraine, Bulgaria, Romania, Russia, Switzerl ...

Barbus Brachycephalus
''Barbus'' is a genus of ray-finned fish in the family Cyprinidae. The type species of ''Barbus'' is the common barbel, first described as ''Cyprinus barbus'' and now named ''Barbus barbus''. ''Barbus'' is the namesake genus of the subfamily Barbinae, but given their relationships, that taxon is better included in the Cyprininae at least for the largest part (including the type species of ''Barbus''). Description and uses Their common names – barbs and barbels – refer to the fact that most members of the genera have a pair of barbels on their mouths, which they can use to search for food at the bottom of the water. Barbels are often fished for food; in some locations they are of commercial significance. The roe of barbels is poisonous, however. The large ''Barbus'' barbs are also often eaten in their native range. At Shanhûr in Egypt, remains of a jar from the sixth- to seventh-century AD were unearthed that contained fish bones. The fish were apparently pickle ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Phytoplankton
Phytoplankton () are the autotrophic (self-feeding) components of the plankton community and a key part of ocean and freshwater ecosystems. The name comes from the Greek words (), meaning 'plant', and (), meaning 'wanderer' or 'drifter'. Phytoplankton obtain their energy through photosynthesis, as do trees and other plants on land. This means phytoplankton must have light from the sun, so they live in the well-lit surface layers (euphotic zone) of oceans and lakes. In comparison with terrestrial plants, phytoplankton are distributed over a larger surface area, are exposed to less seasonal variation and have markedly faster turnover rates than trees (days versus decades). As a result, phytoplankton respond rapidly on a global scale to climate variations. Phytoplankton form the base of marine and freshwater food webs and are key players in the global carbon cycle. They account for about half of global photosynthetic activity and at least half of the oxygen production, despite ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bradt Travel Guides
Bradt Travel Guides is a publisher of travel guides founded in 1974 by Hilary Bradt and her husband George, who co-wrote the first Bradt Guide on a river barge on a tributary of the Amazon River, Amazon. Since then Bradt has grown into a leading independent travel publisher, with growth particularly in the last decade. It has a reputation for tackling destinations overlooked by other guide book publishers. Bradt guides have been cited by ''The Independent'' as covering "parts of the world other travel publishers don't reach", and nearly two-thirds of the guides on the publisher's list have no direct competition in English from other travel publishers. These include guides to parts of Asia, Latin America and Africa, in particular, which traditionally have not been widely covered by guidebook publishers, or do not have a long history of tourism. Bradt also has an extensive list of regional European guides to destinations such as the Peloponnese, the Vendée and the Basque Country (g ...

Tejen River
The Hari River ( or prs, هری رود, translit=Harī Rōd; ps, د هري سیند) or Herat River is a river flowing from the mountains of central Afghanistan to Turkmenistan, where it forms the Tejend oasis and disappears in the Karakum Desert. In its lower course, the river forms a northern part of the border between Afghanistan and Iran, and a southeastern part of the border between Turkmenistan and Iran. In Turkmenistan it is known as the Tejen or Tedzhen river and passes close to the city of Tedzhen. To the Ancient Greeks it was known as the Arius. In Latin, it was known as the Tarius. History Western non Hindu writers claim that Rigveda is said to have recorded the Harirud as the River Sarayu. However, the actual Sarayu is in Uttar Pradesh state of India and arises in Tibetan glaciers near Mt Kailash. It flows through Nepal, before entering India . The river Haroyu is also mentioned in the Avesta. A Buddhist monastery hand-carved in the bluff of the river Harirud exi ...
