Ray-finned Fish
Actinopterygii (; ), members of which are known as ray-finned fish or actinopterygians, is a class of bony fish that comprise over 50% of living vertebrate species. They are so called because of their lightly built fins made of webbings of skin supported by radially extended thin bony spines called '' lepidotrichia'', as opposed to the bulkier, fleshy lobed fins of the sister clade Sarcopterygii (lobe-finned fish). Resembling folding fans, the actinopterygian fins can easily change shape and wetted area, providing superior thrust-to-weight ratios per movement compared to sarcopterygian and chondrichthyian fins. The fin rays attach directly to the proximal or basal skeletal elements, the radials, which represent the articulation between these fins and the internal skeleton (e.g., pelvic and pectoral girdles). The vast majority of actinopterygians are teleosts. By species count, they dominate the subphylum Vertebrata, and constitute nearly 99% of the over 30,000 extant ...

Nam Ngum
Nam Ngum (, ) is a 354 km long river in Laos. It is a major tributary of the Mekong River. Geography The Nam Ngum originates from the northern mountainous region of Xiangkhoang Province and flows south through Vientiane Province joining the Mekong at the capital of Laos, Vientiane (prefecture), Vientiane. The Nam Ngum river basin is home to about one million people in Laos. The current largest dam on Nam Ngum, Nam Ngum Dam (Nam Ngum 1 Hydropower Project) was originally constructed between 1968 and 1971. There are also four other hydropower projects under construction or planned for construction on the Nam Ngum River. Tourism destinations along Nam Ngum include the Nam Ngum Lake, Dansavanh Nam Ngum Resort, and Vang Vieng. The Nam Ngum river basin covers 16,906 square kilometers, including 8,297 km2 of watershed area. The Nam Ngum river basin covers 2.73 percent of the lower Mekong river basin. The water flow of the Nam Ngum River to the Mekong River is 700 m3/s. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Laos
Laos, officially the Lao People's Democratic Republic (LPDR), is the only landlocked country in Southeast Asia. It is bordered by Myanmar and China to the northwest, Vietnam to the east, Cambodia to the southeast, and Thailand to the west and southwest. The country has a population of approximately eight million. Its Capital city, capital and most populous city is Vientiane. The country is characterized by mountainous terrain, Buddhist temples, including the UNESCO's World Heritage Site of Luang Prabang, and French colonial architecture. The country traces its historic and cultural identity to Lan Xang, a kingdom which existed from the 13th to 18th centuries. Through its location, the kingdom was a hub for overland trade. In 1707, Lan Xang split into three kingdoms: Kingdom of Luang Phrabang, Luang Prabang, Kingdom of Vientiane, Vientiane, and Kingdom of Champasak, Champasak. In 1893, these kingdoms were unified under French protection as part of French Indochina. Laos was und ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Mekong
The Mekong or Mekong River ( , ) is a transboundary river in East Asia and Southeast Asia. It is the world's twelfth-longest river and the third-longest in Asia with an estimated length of and a drainage area of , discharging of water annually. From its headwaters in the Tibetan Plateau, the river runs through Southwest China (where it is officially called the Lancang River), Myanmar, Laos, Thailand, Cambodia, and southern Vietnam. The extreme seasonal variations in flow and the presence of rapids and waterfalls in the Mekong make navigation difficult, though the river remains a major trade route between Tibet and Southeast Asia. The construction of hydroelectric dams along the Mekong in the 2000s through the 2020s has caused serious problems for the river's ecosystem, including the exacerbation of drought. Names The Mekong was originally called ''Mae Nam Khong'' from a contracted form of Kra-Dai shortened to ''Mae Khong''. In Thai and Lao, ''Mae Nam'' ("Mother ...

Standard Length
Fish measurement is the measuring of individual fish and various parts of fish anatomy, their anatomies, for data used in many areas of ichthyology, including Taxonomy (biology), taxonomy and fishery 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 Glossary of ichthyology#H, hypural plate. This measurement excludes the length of the caudal fin, 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 Actinopterygii, bony fish), while total length measurements are used with Myxini (hagfish), Petromyzontiformes (lampreys) and usually Elasmobranchii (shark ...

Mekong River Basin Hydropower
The estimated hydropower potential of Mekong River Basin about 58,930 Megawatts (MW). As of February 2024, there are an estimated 167 Hydropower Plants (HPPs) in the Mekong, with a combined installed capacity of some 36,376.3 MW. An additional 20 HPPs are currently under construction and at various stages of completion. These have a combined installed capacity of an additional 4,535.5 MW. The single most significant impact on the use of water and its management in the Mekong Region is hydropower. These developments in the Mekong River Basin have resulted in substantial environmental and social impacts, which are summarised below. These have fuelled controversy and hydropower is a prominent part of the discussion around the river, its basin, and its management. This debate occurs in both the academic literature, as well as the media, and is a focus for many activist groups. The countries that share the Mekong River Basin have all sought the large-scale infrastructural development ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Fish Of The Mekong Basin
A fish (: fish or fishes) is an aquatic animal, aquatic, Anamniotes, anamniotic, gill-bearing vertebrate animal with swimming fish fin, fins and craniate, a hard skull, but lacking limb (anatomy), limbs with digit (anatomy), digits. Fish can be grouped into the more basal (phylogenetics), basal jawless fish and the more common jawed fish, the latter including all extant taxon, living cartilaginous fish, cartilaginous and bony fish, as well as the extinct placoderms and acanthodians. In a break to the long tradition of grouping all fish into a single Class (biology), class (Pisces), modern phylogenetics views fish as a paraphyletic group. Most fish are ectotherm, cold-blooded, their body temperature varying with the surrounding water, though some large nekton, active swimmers like white shark and tuna can hold a higher core temperature. Many fish can communication in aquatic animals#Acoustic, communicate acoustically with each other, such as during courtship displays. The stud ...

Endemic Fauna Of Laos
Endemism is the state of a species being found only in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can also be referred to as an ''endemism'' or, in scientific literature, as an ''endemite''. Similarly, many species found in the Western ghats of India are examples of endemism. Endemism is an important concept in conservation biology for measuring biodiversity in a particular place and evaluating the risk of extinction for species. Endemism is also of interest in evolutionary biology, because it provides clues about how changes in the environment cause species to undergo range shifts (potentially expanding their range into a larger area or becoming ...
