Channa Nox
''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.Kumar, K., R. Kumar, S. Saurabh, M. Sahoo, A.K.

Fish Farming

It is a particular type of aquaculture, which is the controlled cultivation and harvesting of aquatic animals such as fish, crustaceans, molluscs and so on, in natural or pseudo-natural environment. A facility that releases juvenile fish into the wild for recreational fishing or to supplement a species' natural numbers is generally referred to as a fish hatchery. Worldwide, the most important fish species produced in fish farming are carp, catfish, salmon and tilapia. Global demand is increasing for dietary fish protein, which has resulted in widespread overfishing in wild ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Parachanna
''Parachanna'' is a genus of snakeheads native to freshwater habitats in tropical Africa. Three recognized extant (living) species are in this genus, but a phylogenetic study from 2017 indicates that a fourth, currently undescribed species also exists. One fossil species, ''Parachanna fayumensis'' Murray, 2006 dated to the Upper Eocene and Lower Oligocene is known from the Jebel Qatrani Formation of the Fayum Depression, Egypt. Species The three recognized extant species in this genus are: * ''Parachanna africana'' ( Steindachner, 1879) (African snakehead) * ''Parachanna insignis'' ( Sauvage, 1884) (brown snakehead) * ''Parachanna obscura The obscure snakehead, ''Parachanna obscura'', is a medium-sized carnivorous fish that has an elongated shape tapered on both ends and is covered in medium circular scales (cycloid).

Undescribed Species
In taxonomy, an undescribed taxon is a taxon (for example, a species) that has been discovered, but not yet formally described and named. The various Nomenclature Codes specify the requirements for a new taxon to be validly described and named. Until such a description has been published, the taxon has no formal or official name, although a temporary, informal name is often used. A published scientific name may not fulfil the requirements of the Codes for various reasons. For example, if the taxon was not adequately described, its name is called a '' nomen nudum''. It is possible for a taxon to be "undescribed" for an extensive period of time, even if unofficial descriptions are published. An undescribed species may be referred to with the genus name, followed by "sp"., but this abbreviation is also used to label specimens or images that are too incomplete to be identified at the species level. In some cases, there is more than one undescribed species in a genus. In this case, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Phylogenetic
In biology, phylogenetics (; from Greek φυλή/ φῦλον [] "tribe, clan, race", and wikt:γενετικός, γενετικός [] "origin, source, birth") is the study of the evolutionary history and relationships among or within groups of organisms. These relationships are determined by Computational phylogenetics, phylogenetic inference methods that focus on observed heritable traits, such as DNA sequences, protein amino acid sequences, or morphology. The result of such an analysis is a phylogenetic tree—a diagram containing a hypothesis of relationships that reflects the evolutionary history of a group of organisms. The tips of a phylogenetic tree can be living taxa or fossils, and represent the "end" or the present time in an evolutionary lineage. A phylogenetic diagram can be rooted or unrooted. A rooted tree diagram indicates the hypothetical common ancestor of the tree. An unrooted tree diagram (a network) makes no assumption about the ancestral line, and does ...

Magahi
The Magahi language (), also known as Magadhi (), is a language spoken in Bihar, Jharkhand and West Bengal states of eastern India, and in the Terai of Nepal. Magadhi Prakrit was the ancestor of Magahi, from which the latter's name derives. It has a very rich and old tradition of folk songs and stories. It is spoken in nine districts of Bihar ( Gaya, Patna, Jehanabad, Aurangabad, Nalanda, Sheikhpura, Nawada, Lakhisarai, Arwal), eight districts of Jharkhand (Hazaribag, Palamu, Chatra, Koderma, Jamtara, Bokaro, Dhanbad, Giridih) and in West Bengal's Malda district. There are around 20,700,000 speakers of Magahi, including speakers 12 million Magahi and 8 million Khortha which is considered a dialect of Magahi. Magahi derived from the ancient Magadhi Prakrit, which was created in the ancient kingdom of Magadha, the core of which was the area south of the Ganges and east of Son River. Though the number of speakers in Magahi is about 12.6 million, it has not been con ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Assamese Language
Assamese (), also Asamiya ( ), is an Indo-Aryan language spoken mainly in the north-east Indian state of Assam, where it is an official language, and it serves as a ''lingua franca'' of the wider region. The easternmost Indo-Iranian language, it has over 23 million speakers. Nefamese, an Assamese-based pidgin, is used in Arunachal Pradesh, and Nagamese, an Assamese-based Creole language, is widely used in Nagaland. The Kamtapuri language of Rangpur division of Bangladesh and the Cooch Behar and Jalpaiguri districts of India are linguistically closer to Assamese, though the speakers identify with the Bengali culture and the literary language. In the past, it was the court language of the Ahom kingdom from the 17th century. Along with other Eastern Indo-Aryan languages, Assamese evolved at least before the 7th century CE from the middle Indo-Aryan Magadhi Prakrit. Its sister languages include Angika, Bengali, Bishnupriya Manipuri, Chakma, Chittagonian, Hajong, Rajbangsi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Barca Snakehead
The Barca snakehead (''Channa barca'') 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''. This is a relatively large snakehead, reaching a total length of up to . The species is regarded as an excellent food fish, and it is also highly desired by aquarists, but its rarity, behavior and large size makes it unsuitable for most aquariums.SeriouslyFishChanna barca Retrieved 14 February 2019.

Mouthbrooding
Mouthbrooding, also known as oral incubation and buccal incubation, is the care given by some groups of animals to their offspring by holding them in the mouth of the parent for extended periods of time. Although mouthbrooding is performed by a variety of different animals, such as the Darwin's frog, fish are by far the most diverse mouthbrooders. Mouthbrooding has evolved independently in several different families of fish. Mouthbrooding behaviour Paternal mouthbrooders are species where the male looks after the eggs. Paternal mouthbrooders include the arowana, various mouthbrooding bettas and gouramies such as ''Betta pugnax'', and sea catfish such as ''Ariopsis felis''. Among cichlids, paternal mouthbrooding is relatively rare, but is found among some of the tilapiines, most notably the black-chin tilapia ''Sarotherodon melanotheron''. In the case of the maternal mouthbrooders, the female takes the eggs. Maternal mouthbrooders are found among both African and South American ci ...

Dwarf Snakehead
Dwarf snakehead is a term coined by aquarists to describe a group of ''Channa'' snakehead fishes growing to about maximum. They are found in freshwater habitats (often streams) in South and Southeast Asia, and southern China.Endruweit, M. (2017). Description of a new dwarf snakehead (Perciformes: Channidae) from western Yunnan. Vertebrate Zoology 67(2): 173-178. The following snakeheads belong to this group:Lalramliana, J. D. M. Knight, D. V.
