Damba Mipentina
The damba mipentina (''Paretroplus maculatus'') is a critically endangered species of cichlid fish from turbid, shallow flood-plain lakes in the Betsiboka and Ikopa River basins in northwestern Madagascar.Sparks, J. S. (2008). ''Phylogeny of the Cichlid Subfamily Etroplinae and Taxonomic Revision of the Malagasy Cichlid Genus Paretroplus (Teleostei: Cichlidae).'' Bulletin of the American Museum of Natural History Number 314 :1-151 It has declined drastically because of habitat loss, overfishing and invasive species. It is part of a captive breeding program by public institutions like London Zoo and among fishkeeping hobbyists. This relatively deep-bodied ''Paretroplus ''Paretroplus'' is a genus of fishes in the cichlid family, all of which are endemic to lakes and rivers of Madagascar. The vast majority are threatened and restricted to the northwestern part of the island.Sparks, J. S. (2008). ''Phylogeny of t ...'' can easily be distinguished from other members of the genus b ...

London Zoo
London Zoo, also known as ZSL London Zoo or London Zoological Gardens is the world's oldest scientific zoo. It was opened in London on 27 April 1828, and was originally intended to be used as a collection for science, scientific study. In 1831 or 1832, the animals of the Tower of London#Royal Menagerie, Tower of London menagerie were transferred to the zoo's collection. It was opened to the public in 1847. Today, it houses a collection of 673 species of animals, with 19,289 individuals, making it one of the largest collections in the United Kingdom. The zoo is sometimes called Regent's Park Zoo. It is managed under the aegis of the Zoological Society of London (established in 1826), and is situated at the northern edge of Regent's Park, on the boundary line between the City of Westminster and the borough of London Borough of Camden, Camden (the Regent's Canal runs through it). The Society also has a more spacious site at Whipsnade Zoo, ZSL Whipsnade Zoo in Bedfordshire to which t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Cichlid
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 aquariu ...

Betsiboka River
Betsiboka River is a long river in central-north Madagascar. It flows northwestward and empties to Bombetoka Bay, forming a large river delta, delta. It originates to the east of Antananarivo. The river is surrounded in mangroves. The river is distinctive for its red-coloured water, which is caused by river sediments. The river carries an enormous amount of reddish-orange silt to the sea. Much of this silt is deposited at the mouth of the river or in the bay. It is dramatic evidence of the catastrophic erosion of northwestern Madagascar. Removal of the native forest for cultivation and pastureland during the past 50 years has led to massive annual soil losses approaching 250 metric tonnes per hectare (112 tons per acre) in some regions of the island, the largest amount recorded anywhere in the world. Several fish species are Endemism, endemic to the river basin, including the three cichlids ''Kotso, Paretroplus petiti'', ''Paretroplus tsimoly, P. tsimoly'' and ''Damba mipentina, P ...

Ikopa River
The Ikopa River is the second longest waterway in Madagascar and passes through the capital, Antananarivo. It is the largest tributary of the Betsiboka River. It is formed by the Varahina-North and Varahina-South Rivers. Its spring, named Varahina, is found in the sub-prefecture of Andramasina ''For other localities in Madagascar with the same name, please check: '' Andramasina (other) Andramasina is a town in Analamanga Region, in the Central Highlands of Madagascar Madagascar (; mg, Madagasikara, ), officially th ... at an altitude of 1810 meters.

Madagascar
Madagascar (; mg, Madagasikara, ), officially the Republic of Madagascar ( mg, Repoblikan'i Madagasikara, links=no, ; french: République de Madagascar), is an island country in the Indian Ocean, approximately off the coast of East Africa across the Mozambique Channel. At Madagascar is the world's List of island countries, second-largest island country, after Indonesia. The nation is home to around 30 million inhabitants and consists of the island of Geography of Madagascar, Madagascar (the List of islands by area, fourth-largest island in the world), along with numerous smaller peripheral islands. Following the prehistoric breakup of the supercontinent Gondwana, Madagascar split from the Indian subcontinent around 90 million years ago, allowing native plants and animals to evolve in relative isolation. Consequently, Madagascar is a biodiversity hotspot; over 90% of wildlife of Madagascar, its wildlife is endemic. Human settlement of Madagascar occurred during or befo ...

Habitat Loss
Habitat destruction (also termed habitat loss and habitat reduction) is the process by which a natural habitat becomes incapable of supporting its native species. The organisms that previously inhabited the site are displaced or dead, thereby reducing biodiversity and species abundance. Habitat destruction is the leading cause of biodiversity loss. Fragmentation and loss of habitat have become one of the most important topics of research in ecology as they are major threats to the survival of endangered species. Activities such as harvesting natural resources, industrial production and urbanization are human contributions to habitat destruction. Pressure from agriculture is the principal human cause. Some others include mining, logging, trawling, and urban sprawl. Habitat destruction is currently considered the primary cause of species extinction worldwide. Environmental factors can contribute to habitat destruction more indirectly. Geological processes, climate change, introdu ...

Overfishing
Overfishing is the removal of a species of fish (i.e. fishing) from a body of water at a rate greater than that the species can replenish its population naturally (i.e. the overexploitation of the fishery's existing fish stock), resulting in the species becoming increasingly underpopulated in that area. Overfishing can occur in water bodies of any sizes, such as ponds, wetlands, rivers, lakes or oceans, and can result in resource depletion, reduced biological growth rates and low biomass levels. Sustained overfishing can lead to critical depensation, where the fish population is no longer able to sustain itself. Some forms of overfishing, such as the overfishing of sharks, has led to the upset of entire marine ecosystems. Types of overfishing include: growth overfishing, recruitment overfishing, ecosystem overfishing. The ability of a fishery to recover from overfishing depends on whether its overall carrying capacity and the variety of ecological conditions are suitable for t ...

Invasive Species
An invasive species otherwise known as an alien is an introduced organism that becomes overpopulated and harms its new environment. Although most introduced species are neutral or beneficial with respect to other species, invasive species adversely affect habitats and bioregions, causing ecological, environmental, and/or economic damage. The term can also be used for native species that become harmful to their native environment after human alterations to its food webfor example the purple sea urchin (''Strongylocentrotus purpuratus'') which has decimated kelp forests along the northern California coast due to overharvesting of its natural predator, the California sea otter (''Enhydra lutris''). Since the 20th century, invasive species have become a serious economic, social, and environmental threat. Invasion of long-established ecosystems by organisms is a natural phenomenon, but human-facilitated introductions have greatly increased the rate, scale, and geographic range of ...

Captive Breeding
Captive breeding, also known as captive propagation, is the process of plants or animals in controlled environments, such as wildlife reserves, zoos, botanic gardens, and other conservation facilities. It is sometimes employed to help species that are being threatened by the effects of human activities such as climate change, habitat loss, fragmentation, over hunting or fishing, pollution, predation, disease, and parasitism. For many species, relatively little is known about the conditions needed for successful breeding. Information about a species' reproductive biology may be critical to the success of a captive breeding program. In some cases a captive breeding program can save a species from extinction, but for success, breeders must consider many factors—including genetic, ecological, behavioral, and ethical issues. Most successful attempts involve the cooperation and coordination of many institutions. History Captive breeding techniques began with the first human do ...
