Channa harcourtbutleri, the Burmese snakehead, is a species of snakehead endemic to Inle Lake [3] and surroundings [4] in Myanmar. Locally called nga ohn-ma, among aquarists it is considered one of the dwarf snakeheads, but no significant import for aquarists is known. It is one of the smaller species of snakehead and has a standard length of up to 19.4 cm (7.6 in). [2] The specific name honors Sir Harcourt Butler, a British governor in the region. [3]
This was for a long time considered to be a junior synonym of Channa gachua . In fact, both species closely resemble each other. The article on its revalidation [5] only mentions three discriminating features, such as the missing ocellus in the dorsal fin of a juvenile Channa harcourtbutleri. It is suspected to be a mouthbrooder and eats a wide range of foods, including arthropods and small fish, but unlike in some relatives, no frogs.
Chaudhuriidae, is a family of small freshwater eel-like fish related to the swamp eels and spiny eels, commonly known as the earthworm eels. The known species are literally the size and shape of earthworms, thus the family name. While one species, Chaudhuria caudata was reported from the Inle Lake by Nelson Annandale in 1918, the others have been only recently reported, all in the eastern Asia area, from India to Korea.
Channa is a genus of predatory fish in the family Channidae, commonly known as snakeheads, native to freshwater habitats in Asia. This genus contains about 50 scientifically described species. The genus has a wide natural distribution extending from Iraq in the west, to Indonesia and China in the east, and parts of Siberia in the Far East. A particularly high richness of species exists in Myanmar (Burma) and northeastern India, and many Channa species live nowhere else. In contrast, a few widespread species have been introduced to several regions outside their natural range, where they often become invasive. The large and medium-sized Channa species are among the most common staple food fish in several Asian countries, and they are extensively cultured. Apart from their importance as a food fish, snakeheads are consumed in some regions as a traditional medicine for wound healing and reducing postoperative pain and discomfort, and collected for the international aquarium pet trade.
Inle Lake, a freshwater lake located in the Nyaungshwe Township of Shan State, part of Shan Hills in Myanmar (Burma). It is the second largest lake in Myanmar with an estimated surface area of 44.9 square miles (116 km2), and one of the highest at an elevation of 2,900 feet (880 m). During the dry season, the average water depth is 7 feet (2.1 m), with the deepest point being 12 feet (3.7 m). During the rainy season, this can increase by 5 feet (1.5 m).
The Barca snakehead is a rare species of snakehead. It is endemic to the upper Brahmaputra river basin in northeastern India and Bangladesh. Records from Nepal are of doubtful validity. Overall it has been assessed as data deficient by the IUCN, and in 2014 it was assessed as critically endangered in Bangladesh by the IUCN. In Assam, it is locally known as cheng garaka or garaka cheng.
Dwarf snakehead is a term coined by aquarists to describe a group of Channa snakehead fishes growing to about 25 cm (10 in) maximum. They are found in freshwater habitats in South and Southeast Asia, and southern China.
The forest snakehead is a species of snakehead, a fish of the family Channidae. Its range includes most of Southeast Asia and parts of southern China. It lives in forest streams and can reach 40 cm (16 in) in length. The forest snakehead is known in Thai language as pla krasong. Khmer language called it កញ្ជនជៃ, Indonesians named it kehung, while in Malaysia, they called it ikan bujuk in Malay Language
Channa gachua, the dwarf snakehead, is a species of fish in the family Channidae. The name "dwarf snakehead" is also used for several other species of small snakeheads. C. gachua is native to freshwater habitats in southern Asia, where it has a wide distribution from Iran to Indonesia. This fish is considered to be a species complex, a group of several closely related taxa with one name. It is likely at least three to four different species, and further research may differentiate them. A few species such as Channa harcourtbutleri have been separated from the complex in recent decades. The easternmost population of C. gachua is often recognized as a separate species C. limbata, while the isolated Sri Lankan population often is recognized as C. kelaartii.
Channa striata, the striped snakehead, is a species of snakehead fish. It is also known as the common snakehead, chevron snakehead, or snakehead murrel and generally referred simply as mudfish. It is native to South and Southeast Asia, and has been introduced to some Pacific Islands. Reports from Madagascar and Hawaii are misidentifications of C. maculata.
The orange-spotted snakehead is a species of snakehead fish. Its body is of brownish colour intermixed with vertical orange stripes. Males have taller dorsal fins with more intense coloration, and narrower heads. It is endemic to Brahmaputra River basin. Its type locality is Dibrugarh, the most northeastern area of Assam, India. Dibrughar is the same type locality as that of Channa bleheri.
Channa burmanica is a species of snakehead which is endemic to northern Burma. It is a very small species of snakehead included in the informal group of dwarf snakeheads. Its colouring closely resembles that of Channa gachua and Channa bleheri. It is very rarely found in pet shops. It is also considered to be a mouthbrooder species, though no successful breeding has yet occurred.
Channa micropeltes, giant snakehead, giant mudfish or toman harimau, is among the largest species in the family Channidae, capable of growing to 1.5 m (4.9 ft) in length and a weight of 20 kg (44 lb). It is native to the fresh waters of Southeast Asia, but has also been introduced elsewhere and is considered invasive in Taiwan. Other names include xal mas in Assamese, red snakehead, redline snakehead, and ikan toman.
Danio margaritatus, the celestial pearl danio, often referred to in the aquarium trade as galaxy rasbora or Microrasbora sp. 'Galaxy', is a small cyprinid from Myanmar. It has so far been found only in a very small area near Hopong east of Inle Lake, at an elevation of over 1,000 m (3,400 ft). Its habitat is part of the Salween basin, namely the Nam Lang and Nam Pawn Rivers. Discovered in 2006, the species quickly appeared in the aquarium trade, where its small size and bright colours made it an instant hit.
Danio erythromicron, often known as emerald dwarf danio and emerald dwarf rasbora, is a species of cyprinid fish which is endemic to Inle Lake in Myanmar.
The Ceylon snakehead is a species of snakehead found in freshwater habitats, typically shaded streams, in southwestern Sri Lanka.
Channa marulius is a large species of snakehead native to South Asia. Populations in Southeast Asia are now regarded as separate species.
Channa punctata, the spotted snakehead, is a species of snakehead. It is found in the Indian Subcontinent and nearby areas, ranging across Afghanistan, Pakistan, India, Sri Lanka, Nepal, Bangladesh, Myanmar and Tibet. Its natural habitats are swamps, ponds and brackish water systems. It is a fish of high food value and has little value as aquarium fish.
Red dwarf rasbora is a species of cyprinid found endemic to Lake Inle in Shan State in Myanmar. It belongs to the genus Microrasbora, which contains two small species of danionins.
Channa pulchra is a species of snakehead fish in the family Channidae which is native to Myanmar. It was first described in 2007 by R. Britz from a specimen collected from the Kyeintali Chaung (stream) basin in Rakhine Yoma, western Myanmar. The fish is found in streams that are fast flowing, clear, highly oxygenated and relatively cold (subtropical). It is of little food value but getting popularity as an aquarium fish recently.
Channa ornatipinnis is a freshwater species of snakehead, a fish of the family Channidae. It is found in tropical Asia. They can get up to 30.5 cm (12.0 in) long.
Channa aurolineata is a species of Asian snakehead in the family Channidae. It is found natively in most of Myanmar's waterways as well as the Mae Khlong drainage in Thailand. There is also an invasive population found in Southeast Florida, United States. This species was recently split from C. marulius, the bullseye snakehead, and confirmed as a separate species in 2018; and the Florida and Thailand populations were not discovered to be C. aurolineata until even more recently in 2019. Before this, the Thailand population's species was unknown and the Florida ones were assumed to be C. marulius. C. aurolineata was able to be separated as a new species and identified in other areas due to slight differences in color pattern, lateral line scale and fin ray morphology, and DNA structure from the other species in the marulius complex.
