Mouth-brooding
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 cic ...

Tilapia
Tilapia ( ) is the common name for nearly a hundred species of cichlid fish from the coelotilapine, coptodonine, heterotilapine, oreochromine, pelmatolapiine, and tilapiine tribes (formerly all were "Tilapiini"), with the economically most important species placed in the Coptodonini and Oreochromini. Tilapia are mainly freshwater fish inhabiting shallow streams, ponds, rivers, and lakes, and less commonly found living in brackish water. Historically, they have been of major importance in artisanal fishing in Africa, and they are of increasing importance in aquaculture and aquaponics. Tilapia can become a problematic invasive species in new warm-water habitats such as Australia, whether deliberately or accidentally introduced, but generally not in temperate climates due to their inability to survive in cold water. Tilapia has been the fourth-most consumed fish in the United States since 2002. The popularity of tilapia came about due to its low price, easy preparation, and ...

Cyphotilapia Frontosa Mouthbrooding
''Cyphotilapia'' is a small genus of African cichlids endemism, endemic to Lake Tanganyika, with ''C. frontosa'' being roughly confined to the northern half of the lake and ''C. gibberosa'' roughly to the southern half.Takahashi, T. and K. Nakaya (2003). New species of Cyphotilapia (Perciformes: Cichlidae) from Lake Tanganyika, Africa. Copeia 2003(4): 824-832. They have a distinctly banded pattern, bulbous foreheads when mature and can reach up to in length. These are a mouth-brooding cichlid with a rather small batch of fry each spawn. The mother will hold the fry in her mouth for about 3–4 weeks before finally releasing about 30-70 fry. These are slow-growing fish, which take up to 6 years to reach sexual maturity. They can live for up to 25 years. Species There are currently two recognized species in this genus: * ''Cyphotilapia frontosa'' (George Albert Boulenger, Boulenger, 1906) (Humphead cichlid) * ''Cyphotilapia gibberosa'' Tetsumi Takahashi, T.

Channa
''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.

Channidae
The snakeheads are members of the freshwater perciform fish family Channidae, native to parts of Africa and Asia. These elongated, predatory fish are distinguished by their long dorsal fins, large mouths, and shiny teeth. They breathe air with gills, which allows them to migrate short distances over land. They have suprabranchial organs, which are primitive forms of labyrinth organs, that develop when they grow older. The two extant genera are ''Channa'' in Asia and ''Parachanna'' in Africa, consisting of more than 50 species. They are valuable as a food source and have become notorious as an intentionally released invasive species. These fish have been kept as pets but as they get larger, people let them go into ponds, lakes, and rivers, making these fish invasive. Description The various species of snakeheads differ greatly in size; dwarf snakeheads, such as ''Channa orientalis'', do not surpass in length. Most other snakeheads reach between .

Eretmodine
Eretmodini is a tribe of African cichlids. It contains five species of freshwater fish endemic to Lake Tanganyika. They are small fish with reduced swim bladders that are found near the bottom in the turbulent, coastal surf zone.Smith, M.P. (1998). Lake Tanganyikan Cichlids, p. 10. They are mouthbrooders. Genera There are three genera, consisting of five species in the tribe: *''Eretmodus'' Boulenger, 1898 *''Spathodus'' Boulenger, 1900 *''Tanganicodus The spotfin goby cichlid (''Tanganicodus irsacae'') is an African species of cichlid endemic to Lake Tanganyika where it is only known from the northern end of the lake.

Cichlidae
Cichlids are fish from the family Cichlidae in the order Cichliformes. Cichlids were traditionally classed in a suborder, the Labroidei, along with the wrasses ( Labridae), in the order Perciformes, but molecular studies have contradicted this grouping. The closest living relative of cichlids is probably the convict blenny, and both families are classified in the 5th edition of ''Fishes of the World'' as the two families in the Cichliformes, part of the subseries Ovalentaria. This family is both large and diverse. At least 1,650 species have been scientifically described, making it one of the largest vertebrate families. New species are discovered annually, and many species remain undescribed. The actual number of species is therefore unknown, with estimates varying between 2,000 and 3,000. Many cichlids, particularly tilapia, are important food fishes, while others, such as the ''Cichla'' species, are valued game fish. The family also includes many popular freshwater aquar ...

Bagrus Meridionalis
The kampango or kampoyo (''Bagrus meridionalis'') is a critically endangered species of large and predatory bagrid catfish that is endemic to Lake Malawi, Lake Malombe and the upper Shire River in Africa. It prefers areas near rocks in water shallower than , but it also occurs deeper (not beyond the oxygen limit) and over a sandy or muddy bottom. Appearance and behavior The kampango is among the largest fish in the Lake Malawi basin, reaching up to about long, Konings, Ad (1990). ''Ad Konings' Book of Cichlids and all the other Fishes of Lake Malawi,'' p. 487. or possibly even . A common length is around and females are typically larger than males. Adults are overall blackish, while young are grey with dark spots. During the day kampangos hide in caves, but around dusk or dawn they hunt and eat their prey, primarily cichlids. Breeding The male digs a shallow nest in the sandy bottom, often near rocks, where the female lays several thousand eggs. After hatching, the young mos ...

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] |
Ariidae
The Ariidae or ariid catfish are a family of catfish that mainly live in marine waters with many freshwater and brackish water species. They are found worldwide in tropical to warm temperate zones. The family includes about 143 species. Taxonomy The relationships of this family are not yet clear. Two of the genera, '' Gogo'' and '' Ancharius'', have been moved to a separate family called Anchariidae. The Ariidae are divided into three subfamilies: ''Galeichthys'' is the only genus classified in the subfamily Galeichthyinae and similarly '' Bagre'' is the only genus in the subfamily Bagreinae, while the rest of the genera are classified in the subfamily Ariinae. Previously, the family Ariidae has been grouped in the superfamily Doradoidea, but then it was moved into Bagroidea (along with Austroglanididae, Claroteidae, Schilbeidae, Pangasiidae, Bagridae, Malapteruridae, and Pimelodidae. It has also been classified in a superfamily Arioidea containing Ariidae and Anchariidae. Dis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Apogonidae
Cardinalfishes are a family, Apogonidae, of ray-finned fishes found in the Atlantic, Indian, and Pacific Oceans; they are chiefly marine, but some species are found in brackish water and a few (notably ''Glossamia'') are found in fresh water. A handful of species are kept in the aquarium and are popular as small, peaceful, and colourful fish. The family includes about 370 species. They are generally small fish, with most species being less than , and are often brightly coloured. They are distinguished by their large mouths, and the division of the dorsal fin into two separate fins. Most species live in tropical or subtropical waters, where they inhabit coral reefs and lagoons. They are nocturnal, spending the day in dark crevices within the reef. At least some species brood their eggs inside the mouths of the males. Males do not feed during this incubation period. Males incubate the eggs in their mouth due to having longer heads and a larger jaw, which females do not acquire.Hoey ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Brood Parasite
Brood parasites are animals that rely on others to raise their young. The strategy appears among birds, insects and fish. The brood parasite manipulates a host, either of the same or of another species, to raise its young as if it were its own, usually using egg mimicry, with eggs that resemble the host's. The evolutionary strategy relieves the parasitic parents from the investment of rearing young. This benefit comes at the cost of provoking an evolutionary arms race between parasite and host as they coevolve: many hosts have developed strong defenses against brood parasitism, such as recognizing and ejecting parasitic eggs, or abandoning parasitized nests and starting over. It is less obvious why most hosts do care for parasite nestlings, given that for example cuckoo chicks differ markedly from host chicks in size and appearance. One explanation, the mafia hypothesis, proposes that parasitic adults retaliate by destroying host nests where rejection has occurred; there is ...
