Betta Hendra
''Betta hendra'' is a species of gourami. It is native to Asia, where it occurs in the Sabangau River basin in Central Kalimantan on the island of Borneo in Indonesia. It is typically found among plants in peat swamp forests shaded by trees and bushes with a depth of 5 to 50 cm (2 to 19.7 inches) and no water current. Based on aquarium observations, the species forms bubble nests. The species reaches 4.2 cm (1.7 inches) in standard length 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.

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] |
Gourami
Gouramis, or gouramies , are a group of freshwater anabantiform fishes that comprise the family Osphronemidae. The fish are native to Asia—from the Indian Subcontinent to Southeast Asia and northeasterly towards Korea. The name "gourami", of Indonesian origin, is also used for fish of the families Helostomatidae and Anabantidae. Many gouramis have an elongated, feeler-like ray at the front of each of their pelvic fins. All living species show parental care until fry are free swimming: some are mouthbrooders, like the Krabi mouth-brooding betta (''Betta Simplex''), and others, like the Siamese fighting fish (''Betta splendens''), build bubble nests. Currently, about 133 species are recognised, placed in four subfamilies and about 15 genera. The name Polyacanthidae has also been used for this family. Some fish now classified as gouramis were previously placed in family Anabantidae. The subfamily Belontiinae was recently demoted from the family Belontiidae. As labyrinth fishe ...

Asia
Asia (, ) is one of the world's most notable geographical regions, which is either considered a continent in its own right or a subcontinent of Eurasia, which shares the continental landmass of Afro-Eurasia with Africa. Asia covers an area of , about 30% of Earth's total land area and 8.7% of Earth's total surface area. The continent, which has long been home to the majority of the human population, was the site of many of the first civilizations. Its 4.7 billion people constitute roughly 60% of the world's population. In general terms, Asia is bounded on the east by the Pacific Ocean, on the south by the Indian Ocean, and on the north by the Arctic Ocean. The border of Asia with Europe is a historical and cultural construct, as there is no clear physical and geographical separation between them. It is somewhat arbitrary and has moved since its first conception in classical antiquity. The division of Eurasia into two continents reflects East–West cultural, linguistic, ...

Sabangau River
Sabangau National Park (sometimes spelled Sebangau) is a national park in Central Kalimantan, a province of Indonesia in Kalimantan, the Indonesian part of the island of Borneo established in 2004. Between 1980 and 1995 the site was a massive logging concessions area. After 1995, the park became a site for illegal logging, which resulted in up to 85 percent of the 568,700-hectare total park area being destroyed. By 2012, less than 1 percent of the park's total area has been reforested and several centuries is needed to restore it to its pre-logged state. Geography The national park is centered on Sabangau River, a blackwater river. It flows through the Kelompok Hutan Kahayan or Sabangau peat swamp forest (5,300 km2), between the Katingan and Kahayan rivers. The peat swamp forest is a dual ecosystem, with diverse tropical trees standing on a 10m - 12m layer of peat - partly decayed and waterlogged plant material - which in turn covers relatively infertile soil.

Central Kalimantan
Central Kalimantan ( id, Kalimantan Tengah) is a province of Indonesia. It is one of five provinces in Kalimantan, the Indonesian part of Borneo. Its provincial capital is Palangka Raya and in 2010 its population was over 2.2 million, while the 2015 Intermediate Census showed a rise to 2.49 million and the 2020 Census showed a total of 2.67 million. The population growth rate was almost 3.0% per annum between 1990 and 2000, one of the highest provincial growth rates in Indonesia during that time; in the subsequent decade to 2010 the average annual growth rate slowed markedly to around 1.8%, but it rose again in the decade beginning 2010. More than is the case in other province in the region, Central Kalimantan is populated by the Dayaks, the indigenous inhabitants of Borneo. History Since the eighteenth century the central region of Kalimantan and its Dayak inhabitants were ruled by the Muslim Sultanate of Banjar. Following Indonesian independence after World War II, Dayak trib ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Borneo
Borneo (; id, Kalimantan) is the third-largest island in the world and the largest in Asia. At the geographic centre of Maritime Southeast Asia, in relation to major Indonesian islands, it is located north of Java, west of Sulawesi, and east of Sumatra. The island is politically divided among three countries: Malaysia and Brunei in the north, and Indonesia to the south. Approximately 73% of the island is Indonesian territory. In the north, the East Malaysian states of Sabah and Sarawak make up about 26% of the island. The population in Borneo is 23,053,723 (2020 national censuses). Additionally, the Malaysian federal territory of Labuan is situated on a small island just off the coast of Borneo. The sovereign state of Brunei, located on the north coast, comprises about 1% of Borneo's land area. A little more than half of the island is in the Northern Hemisphere, including Brunei and the Malaysian portion, while the Indonesian portion spans the Northern and Southern hemisph ...

Peat Swamp Forest
Peat swamp forests are tropical moist forests where waterlogged soil prevents dead leaves and wood from fully decomposing. Over time, this creates a thick layer of acidic peat. Large areas of these forests are being logged at high rates. Peat swamp forests are typically surrounded by lowland rain forests on better-drained soils, and by brackish or salt-water mangrove forests near the coast. Tropical peatlands, which coexist with swamp forests within the tropical and subtropical moist broadleaf forests biome, store and accumulate vast amounts of carbon as soil organic matter - much more than natural forests contain. Their stability has important implications for climate change; they are among the largest near-surface reserves of terrestrial organic carbon. Peat swamp forests, which have ecological importance, are one of the most threatened, yet least studied and most poorly understood biotypes. Since the 1970s, peat swamp forest deforestation and drainage have greatly increase ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bubble Nest
Bubble nests, also called foam nests, are created by some fish and frog species as floating masses of bubbles blown with an oral secretion, saliva bubbles, and occasionally aquatic plants. Fish that build and guard bubble nests are known as aphrophils. Aphrophils include gouramis (including ''Betta'' species) and the synbranchid eel ''Monopterus alba'' in Asia, ''Microctenopoma'' ( Anabantidae), ''Polycentropsis'' (Nandidae), and '' Hepsetus odoe'' (the only member of Hepsetidae) in Africa, and callichthyines and the electric eel in South America. Most, if not all, fish that construct floating bubble nests live in tropical, oxygen-depleted standing waters. Osphronemidae, containing the Bettas and Gouramies, are the most commonly recognized family of bubble nest makers, though some members of that family mouthbrood instead. The nests are constructed as a place for fertilized eggs to be deposited while incubating and guarded by one or both parents (usually solely the male) until ...

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.
