Gambusia is a large genus of viviparous fish in the family Poeciliidae (order Cyprinodontiformes). Gambusia contains over 40 species, most of which are principally found in freshwater habitats, though some species may also be found in brackish or saltwater habitats. The genus Gambusia comes from the Cuban term, "Gambusino", which means "free-lance miner". [3] The type species is the Cuban gambusia, G. punctata. The greatest species richness is in Mexico, Texas, and the Greater Antilles, but species are also found elsewhere in the eastern and southern United States, the Bahamas, Central America, and Colombia. Gambusia species are often called topminnows, or simply gambusias; they are also known as mosquitofish, which, however, refers more specifically to two species, G. affinis and G. holbrooki , which are often introduced into ponds to eat mosquito larvae. [4] [5] As a consequence, they have been introduced widely outside their native range, and frequently become invasive, threatening local species. [6] G. affinis and G. holbrooki are now established in many parts of the world and are likely to continue to spread as climatic conditions change. [7] They are only occasionally kept in aquariums, due to their relative lack of color and the highly aggressive nature of the aforementioned mosquitofish species.

The Poeciliidae are a family of freshwater fishes of the order Cyprinodontiformes, the tooth-carps, and include well-known live-bearing aquarium fish, such as the guppy, molly, platy, and swordtail. The original distribution of the family was the Southeastern United States to north of Río de la Plata, Argentina, and Africa, including Madagascar. Due to release of aquarium specimens and the widespread use of species of the genera Poecilia and Gambusia for mosquito control, though, poeciliids can today be found in all tropical and subtropical areas of the world. In addition, Poecilia and Gambusia specimens have been identified in hot springs pools as far north as Banff, Alberta.

The western mosquitofish is a North American freshwater poeciliid fish, also known commonly, if ambiguously, as simply mosquitofish or by its generic name, Gambusia, or by the common name gambezi. Its sister species, the eastern mosquitofish is also referred to by these names.

<i>Poecilia</i> Genus of fishes

Poecilia is a genus of fishes in the family Poeciliidae of the order Cyprinodontiformes. These livebearers are native to fresh, brackish and salt water in the Americas, and some species in the genus are euryhaline. A few have adapted to living in waters that contain high levels of toxic hydrogen sulfide and a population of P. mexicana lives in caves.

The widemouth gambusia is a species of fish in the family Poeciliidae of the order Cyprinodontiformes. It is endemic to Mexico, specifically to the Baños del Azufre near Teapa, Tabasco. The Baños del Azufre are sulfidic springs that contain high concentrations of toxic hydrogen sulfide. This prevents most animals from living in them; the only other fish found in the toxic sections of Baños del Azufre is the sulphur molly.

<span class="mw-page-title-main">Mosquitofish in Australia</span> Introduced pest species of fish in Australia

The eastern mosquitofish was introduced to Australia in 1925, and had spread from the northeast coasts to New South Wales, southern Australia, and parts of Western Australia by 1934. By the 21st century, known populations of wild mosquitofish had occurred in every state and territory except the Northern Territory, found in swamps, lakes, billabongs, thermal springs, salt lakes, and ornamental ponds. Mosquitofish are considered a noxious pest, especially in New South Wales and Queensland, and it is illegal to release them into the wild or transport them live into any of the states or territories. Mosquitofish were introduced by military and local councils to control mosquito populations; however, there has been no evidence that Gambusia has had any effect in controlling mosquito populations or mosquito-borne diseases. Studies have shown that Gambusia can suffer mortalities if fed only on mosquito larvae, and survivors show poor growth and maturation. Gambusia typically eat zooplankton, beetles, mayflies, caddis flies, mites and other invertebrates; mosquito larvae make up only a small portion of their diet.

Carlhubbsia is a genus of poeciliids native to Guatemala and Mexico. The name of this genus honours the American ichthyologist Carl Leavitt Hubbs (1894-1979) who originally named the genus Allophallus, a name which was preoccupied by a genus of Diptera.

Girardinus is a genus of poeciliids native to Cuba. The name of this genus honours the French zoologist Charles Frédéric Girard (1822-1895) for his work on the freshwater fish of North America.

Gambusia quadruncus, known as the llanos mosquitofish, is a species of bony fish in the genus Gambusia, part of the family Poeciliidae, that lives in east-central Mexico. Sometimes coexisting with at least three similar species, it differs from its closest relative, Gambusia affinis, in several characteristics with plausible effects on reproductive isolation.

"Combined analysis of mitochondrial and nuclear gene sequence data indicates reciprocal monophyly of the species and its sister species Gambusia affinis, with levels of genetic divergence suggesting the two species diverged from one another over a million years ago. The origin of Gambusia quadruncus may reflect a vicariant event associated with Pliocene orogenesis in the Tamaulipas Arch and a frontal section of the Sierra Madre Oriental ."

<span class="mw-page-title-main">Poeciliinae</span> Subfamily of fishes

Poeciliinae is a subfamily of killifish from the family Poeciliidae which contains species from the Americas which are collectively known as the livebearers because many, but not all, of the species within the subfamily are ovoviviparous.

<span class="mw-page-title-main">Gambusiini</span> Tribe of fishes

Gambusiini, also spelled Gambusini, is a tribe of killifishes from the "livebearer" family Poeciliidae. Their native range encompasses Central and much of North America, with a single species Gambusia lemaitrei occurring in South America. Some species have been widely introduced outside their native range and the Eastern mosquitofish Gambusia holbrooki is considered to be one of the 100 worst invasive species in the world and is responsible for declines in small native aquatic species worldwide.
