Bagridae
The Bagridae are a family of catfish that are native to Africa ('' Bagrus'') and Asia (all other genera) from Japan to Borneo. It includes about 245 species. These fish are commonly known as naked catfishes or bagrid catfishes. Many large bagrids are important as a source of food. Some species are also kept as aquarium fishes. Physical characteristics The dorsal fin is preceded by a spine. The adipose fin is present and can have a relatively long base in some species. The pectoral fin spine can be serrated. The body is completely naked (they have no scales). The maximum length is about . Fishes of the family Bagridae have four pairs of well-developed barbels covered by a layer of taste bud-enriched epithelium. Taxonomy The taxonomy of this family has changed rapidly. Nelson (2006) comments how "the family is very different from that recognized in Nelson (1994)". Claroteidae and Austroglanididae contain species that were previously bagrids. Auchenoglanididae is considered by some ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mystus
''Mystus'' is a genus of fish in the family Bagridae native to Asia. Phylogenetic relationships within this genus are poorly understood, though it has been suggested that there are two major lineages. Species There are currently 46 recognized species in this genus: * '' Mystus abbreviatus'' (Valenciennes, 1840) * '' Mystus alasensis'' H. H. Ng & Hadiaty, 2005 * '' Mystus albolineatus'' T. R.

Batasio
''Batasio'' is a genus of catfish of the family (biology), family Bagridae. These small fish are found in fast-flowing hillstreams throughout South Asia, South and mainland Southeast Asia. Taxonomy ''Batasio'' was first described by Edward Blyth in 1860 with ''Batasio buchanani'' (a needless renaming of ''Batasio batasio'') designated as biological type, type. ''B. pakistanicus'', described in 1989, is tentatively placed in ''Batasio'', but its generic placement is questionable. Species There are currently 17 recognized species in this genus: * ''Batasio affinis'' Edward Blyth, Blyth, 1860 * ''Batasio batasio'' (Francis Buchanan-Hamilton, F.

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] |
Hemibagrus
''Hemibagrus'' is a genus of catfishes ( order Siluriformes) of the family Bagridae. The genus ''Hemibagrus'' is known from Southeast Asia, India, and southern China. Members of this genus are found ubiquitously in river drainages east of the Ganges-Brahmaputra basin and south of the Yangtze basin, and reach their greatest diversity in Sundaland. This genus consists of large-sized catfishes. '' H. wyckioides'' is the largest Bagrid catfish in central Indochina and may reach 80 kilograms. It includes species with depressed (flattened) heads, rugose (ridged or wrinkled) head shields not covered by skin, and moderately long adipose fins. In Southeast Asia, ''Hemibagrus'' species are an important source of animal protein. The extinct species, '' H. major'', is a fossil species from a Miocene lake fauna from what is now Ban Nong Pia, Phetchabun Province of Thailand. Species There are currently 41 recognized species in this genus: * ''Hemibagrus amemiyai'' ( Sh. Kimura, 1934 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rita (fish)
''Rita'' is a genus of fish in the family Bagridae found in South Asia. These species have a single pair of mandibular barbels, an elongated Weberian apparatus firmly sutured to the basioccipital and the sensory canal on the posttemporal enclosed with bone.Ng, H.H. (2004)''Rita macracanthus'', a new riverine catfish (Teleostei: Bagridae) from South Asia.''Zootaxa, 568: 1–12.'' Species There are currently 7 recognized species in this genus: * '' Rita bakalu'' K.

Pseudomystus
''Pseudomystus'' is a genus of catfishes (order Siluriformes) of the family Bagridae. Taxonomy ''Pseudomystus'' was originally described by Jayaram in 1968 as a subgenus to ''Leiocassis''. It was elevated to genus rank in 1991 by Mo. There is evidence to indicate that these two genera are not even closely related. There is the possibility that ''Pseudomystus'' as currently understood may not be monophyletic. ''P. carnosus'', ''P. fumosus'' and ''P. moeschii'' are hypothesized to form a monophyletic group. However, ''Pseudomystus'' has been treated in some recent literature as a synonym of ''Leiocassis''. Species There are currently 19 described species in this genus: * '' Pseudomystus bomboides'' Kottelat, 2000 * '' Pseudomystus breviceps'' (Regan, 1913) * '' Pseudomystus carnosus'' H. H. Ng & K. K.

Horabagrus
''Horabagrus'' is a genus of catfish in the family Horabagridae endemic to rivers in the Western Ghats in Kerala and Karnataka, India. ''H. brachysoma'' is an important food fish and members of this genus can be found in the aquarium trade. Taxonomy The genus ''Horabagrus'' is usually classified under the family Bagridae, but there are disagreements. The genus name is after the Indian zoologist Sunder Lal Hora. Though listed under Bagridae, ''Horabagrus'' is not listed under either of the two Bagrid subfamilies by the All Catfish Species Inventory. In Nelson (2006), the genus is provisionally placed in the family Schilbeidae, where it is sometimes recognized as its own subfamily. In de Pinna (1998), this genus is classified as sister to the catfishes Pangasiidae and above, which would require a separate family. This genus has also been classified in its own family Horabagridae. In a 2007 paper, ''Horabagrus'' was not classified under any current catfish families. In 2016, Wang ...

Olyra (fish)
''Olyra'' is a genus of catfishes of the family Bagridae. This genus occurs throughout South Asia and western Indochina, from India to western Thailand. In Asia, ''Olyra'' species are known as fighting catfish; they are placed in small aquaria to battle one another similar to Siamese fighting fish, and money is bet on the outcome. Taxonomy The genus ''Olyra'' is considered by some authorities to belong to the family Bagridae, though Olyridae is considered valid by Fishbase. The taxonomic status of ''O. colletii'' has been a puzzle. It was first described in 1881 by Franz Steindachner as ''Heptapterus collettii'' and marked as neotropical in origin. With examination, though, it was determined to more closely match members of ''Olyra''. It may even be a junior synonym of ''Olyra longicaudata''. ''O. kempi'' is treated in some literature as a synonym of ''O. longicaudata''. Species There are currently 8 recognized species in this genus: * '' Olyra astrifera'' Arunachalam, Raja, ...

Pseudobagrus
''Pseudobagrus'' is a genus of bagrid catfishes that inhabit streams and rivers throughout East Asia. About half of these species occur in China. The two ''Coreobagrus'' species, ''C. brevicorpus'' and ''C. ichikiwai'', are both treated in some recent literature as valid in ''Pseudobagrus''. It has been noted that ''Pelteobagrus'' may not be monophyletic if species placed in ''Pseudobagrus'' and ''Coreobagrus'' were excluded. The taxonomy of this genus is unclear and many authorities treat it as a junior synonym of ''Tachysurus''. ''Pseudobagrus'' species are small- to mid-sized bagrid catfishes. These fish all have an inferior mouth; narial openings widely separated; four pairs of barbels; top of head covered by skin in most species; two dorsal fin spines; pelvic fin small; and caudal fin emarginate, truncate or round. One fossil species, '' P. ikiensis'' Watanabe & Uyeno, is known from the Middle Miocene of Japan.Watanabe, K. and Uyeno, T.; ''Fossil bagrid catfishes from Japa ...

Leiocassis
''Leiocassis'' is a genus of bagrid catfishes found mostly in Southeast Asia with some species occurring in China. This genus has a confused taxonomy and there is uncertainty surrounding the number of valid species. Certain East Asian bagrids formerly placed in this genus have been moved to ''Pseudobagrus''. In 2006, Heok Hee Ng considered the genus ''Leiocassis'' to be restricted to Sundaic Southeast Asia and Borneo and only a handful of species as valid (''L. aculeatus'', ''L. collinus'', ''L. hosii'', ''L. micropogon'', ''L. poecilopterus'', and ''L. tenebricus''). The members of ''Leiocassis'' have an elongate narrow head and a prominently protruding snout. Species There are currently 14 recognized species in this genus: * '' Leiocassis aculeatus'' H. H. Ng & Hadiaty, 2005 * '' Leiocassis bekantan'' H. H. Ng & H. H. Tan, 2018 * '' Leiocassis brevirostris'' V. H. Nguyễn, 2005 * '' Leiocassis collinus'' H. H. Ng & K. K. P.

Bagrichthys
''Bagrichthys'' is a genus of bagrid catfishes. Taxonomy This genus is most closely related to the genus '' Bagroides''. In turn, these two genera are most closely related to ''Leiocassis''. The genus can be split into two lineages. ''B. hypselopterus'', ''B. macracanthus'', ''B. majusculus'', and ''B. vaillantii'' have long dorsal fins with 18 or more serrations in adults, while ''B. macropterus'', ''B. micranodus'', and ''B. obscurus'' have short dorsal fins with 15 or fewer serrations in adults. The first lineage is more derived, while the second lineage is more basal. Species This genus currently contains seven described species: * '' Bagrichthys hypselopterus'' (Bleeker, 1852) * '' Bagrichthys macracanthus'' (Bleeker, 1854) (Black lancer, Black lancer catfish) * '' Bagrichthys macropterus'' (Bleeker, 1854) (False black lancer, False black lancer catfish) * '' Bagrichthys majusculus'' H.
