Synocrossus beauforti, the barred loach,chameleon loach or chameleon botia, is a species of freshwater fish from the loach family Botiidae which is found in mainland south-east Asia.
Syncrossus beauforti resembles Syncrossus berdmorei but has 11-14 dorsal fin rays as opposed to 9–10 in S. berdmorei. Tn both species there are rows of small, dark spots running along the length of the body and the head, but in S. beauforti these markings are a slightly smaller and it has 9-12 faint vertical bars on its body. As the fish matures bars may fade leaving the longitudinal rows of dark markings. The dorsal fin has a black margin and 3 rows of spots, while the caudal fin has several vertical rows of spots. When excited, these fish are able to produce clicking sounds. [3] They grow to a maximum length of 25 cm standard length. [4]
Syncrossus beauforti is found in south-east Asia and the species was originally described from specimens taken in a stream in Nakhon Si Thammarat Province in southern Thailand and was then recorded in Trang Province and has now been found to occur in the basin of the Salween River on the borders between Thailand and Myanmar and the Chao Phraya River system in western and central Thailand. Records from the Mekong are now attributed to two separate species, S, yunnanensis and S. formosanus [5] which may be synonyms of Syncrossus lucasbahi . [6]
Syncrossus beauforti occurs in the demersal zone of small and medium-sized rivers and it is habitually associated with streams which clear and fast flowing with a stony or rocky substrate, [1] with large amounts of wood debris and leaf litter. [5] It may enter flooded forest during the high-water periods during the monsoon and returns to the rivers during November and December. It digs burrows in sand or excavates them under rocks. [1] It is omnivorous with the bulk of its diet being made up of insect larvae and benthic animals. [3] Species in the genus Syncrossus are sociable and are known to form dominance hierarchies within social groups and to undertake ritualised behaviours to determine their place in the hierarchy. These fish possess sharp sub-ocular spines which they can move, these are normally hidden inside a pouch of skin but when the fish is stressed it can erect these spines. In addition they make sounds when excited but the purpose of the sounds is unknown. [5]
Syncrossus beauforti is sometimes recorded in fish markets being sold for human consumption. It is an aquarium fish but it has not been known to have been bred in captivity so all of the individuals traded are assumed to have been caught in the wild. The taking of specimens for this trade appears to be the principal threat to this species. [1] It is also threatened by pollution and by the damming of the rivers it occurs in which may prevent the fish from migrating to its spawning areas during the periods of flooding, as well as increasing sedimentation and causing habitat degradation. The population is thought to be decreasing but the population size and extent of the decline is unknown. [1]
Syncrossus berdmorei is a freshwater fish in the loach family Botiidae. It is native to streams and rivers in Thailand, Burma, and nearby parts of northeastern India, where typically found over a soft bottom near boulders and submerged trees. Syncrossus berdmorei grows up to 10 in (25 cm) and can be kept in private aquariums.
The stone loach is a European species of fresh water ray-finned fish in the family Nemacheilidae. It is one of nineteen species in the genus Barbatula. Stone loaches live amongst the gravel and stones of fast flowing water where they can search for food. The most distinctive feature of this small fish is the presence of barbels around the bottom jaw, which they use to detect their invertebrate prey. The body is a mixture of brown, green and yellow.
Acrochordonichthys is a genus of catfishes of the family Akysidae. It includes ten species.
The Thai whiting, Sillago intermedius, is a species of coastal marine fish of the smelt-whiting family Sillaginidae. The Thai whiting ranges from the west coast of India to the Gulf of Thailand in the east, inhabiting silty substrates in shallow waters. First identified in 1977 from a specimen found in a fish market, the species has had little research performed on its biology, and is frequently misidentified as Sillago sihama or Sillago maculata Thai whiting are commonly caught by fishermen throughout their range and are marketed fresh locally.
The loach goby, Rhyacichthys aspro, is a goby belonging to the family Rhyacichthyidae. It is not fished commercially.
The Soringa whiting, Sillago soringa, is a poorly known species of coastal marine fish of the smelt-whiting family, Sillaginidae. The Soringa whiting is known exclusively from the east coast of India, inhabiting shallow inshore environments, particularly sandy substrates. S. soringa was first described in 1982 by Dutt and Sujatha, with the taxonomic status of the species was questioned by Roland McKay in his review of the Sillaginidae, with similar features to S. asiatica suggesting it is a senior synonym of the latter.
The brownback trevally, also known as the brown-backed trevally, is a species of small inshore marine fish classified in the jack family, Carangidae. The brownback trevally is distributed in two populations through the tropical waters of the Indo-west Pacific region, ranging from the Persian Gulf east to India, South East Asia and the Indonesian islands. The species is distinguished from similar species by its completely scaled breast and black-tipped second dorsal fin, and is known to reach a maximum length of 25 cm. The brownback trevally inhabits inshore waters including bays and estuaries, where it preys on demersal crustaceans and small fish. Other aspects of its biology are poorly known, and it is of minor importance to fisheries, occasionally caught by hook and line or trawls. William Smith-Vaniz has recently suggested the two distinct populations may actually represent two distinct species.
The longfin crevalle jack is a recently described species of large marine fish classified in the jack family, Carangidae. It inhabits the subtropical waters of the east Atlantic Ocean, ranging along the African coast from Mauritania south at least to Moçamedes in southern Angola, with the species historically present in the Mediterranean Sea. It is an inshore species, known to occasionally penetrate estuaries, possibly to spawn. The species is very similar to the crevalle jack, Caranx hippos, and is separated by its extended dorsal and anal fin lobes as well as more detailed anatomical features including dorsal and anal fin ray counts. The fish is known to reach 127 cm in length and 20.9 kg in weight. The longfin crevalle jack is a predatory fish, taking small fish as its main prey. Due to longstanding confusion between C. fischeri and C. hippos, the importance of each species to African fisheries is poorly understood, with a known combined catch in this region of between 2,233 and 10,054 tonnes per year in 1995–2004. Like its close relatives, the species is considered a powerful gamefish and highly sought after, although their coarse flesh makes for relatively poor quality food.
The Cambodian logsucker, also known as stonelapping minnow or false Siamese algae eater, is a species of ray-finned fish in the genus Garra. It is found in Southeast Asia.
The redeye barb or Beira barb, is a widespread African species of freshwater cyprinid fish which is found from Uganda south to the Limpopo River and Incomati River systems in South Africa.
Hypsibarbus lagleri is a species of ray-finned fish in the genus Hypsibarbus which is endemic to the middle Mekong basin in Cambodia, Laos and Thailand. It is fished for as a food fish and marketed fresh.
The smallscale archerfish is a perciform fish of genus Toxotes. As its name suggests, the scales of the smallscale archerfish are smaller than those of other archerfish. They reach a maximum length of 15 centimetres (5.9 in). Smallscale archerfish live in the tropical Indo-Pacific region and are potamodromous, moving between fresh and brackish water through their lifetimes.
Syncrossus is a genus of six loaches, many of which are popular in the aquarium fish trade. They are primarily found in Southeast Asia, but S. berdmorei also occurs marginally outside this region in far northeastern India. It is one of eight genera in its family.
The West African bichir or retropinnis bichir, is a freshwater fish in the family Polypteridae, is found in the central Congo River basin and Ogooué River in Africa. It is a long, slender fish that grows to a maximum length of about 34 cm (13 in).
The spotfin burrfish, also called the spotted burrfish, Pacific burrfish, spotfin porcupinefish, few-spined porcupinefish, spotfin porcupinefish or few-spined porcupinefish, is a species of fish in the genus Chilomycterus, which is part of the porcupinefish family Diodontidae.
Syncrossus helodes, commonly known as banded loach, tiger botia or lesser katy loach, is a freshwater fish in the loach family Botiidae. It is native to rivers in Vietnam, Thailand, Laos and Cambodia. S. helodes resembles S. hymenophysa from Borneo, Sumatra and Peninsular Malaysia, and the two have frequently been confused. It differs from the latter species by the absence of a dark spot on the dorsal fin, 10–12 bars on body without blue borders and the presence of irregular dark markings on the lower body.
The Indian Scad, also known as the Northern mackerel scad, round scad, Russell's mackerel scad, slender scad or the three lined grunter, is a species of ray-finned fish of the genus Decapterus which is part of the family Carangidae and which occurs in the Indian Ocean. It has colonised the eastern Mediterranean through the Suez Canal. It is an important species in coastal fisheries throughout its range.
Terapon puta, the spiny-checked grunter, three-lined grunter, small-scaled banded grunter, small-scaled terapon, squeaking perch or two-lined grunter, is a species of fish from the Indo-Pacific region, it is a member of the grunter family, Terapontidae. It has also spread into the eastern Mediterranean Sea from the Red Sea through the Suez Canal, a process known as Lessepsian migration.
The broomtail grouper or mangrove grouper is a species of ray-finned fish from the family Serranidae which is found in the eastern Pacific along the western coast of the Americas from California to Peru.
