Summary of InvasivenessTop of page
The eastern mosquitofish Gambusia holbrooki is an exotic fish, which is now widespread around the globe and is known to adversely affect native fish through competition and/or predation. G. holbrooki is known to impact upon native fish via competition with similar sized species, predation upon the fry and eggs of native fish, and by attacking all sized fish by aggressive fin-nipping, thereby leaving them susceptible to disease (Arthington, 1991). G. holbrooki can rapidly increase in population size due to its rapid maturation to breeding age (four weeks in summer) and high survival rate of young (Milton and Arthington, 1983; Lloyd et al., 1986; Lloyd, 1990).

Notes on Taxonomy and NomenclatureTop of page
DescriptionTop of page
The male G. holbrooki is about 35 mm standard length whereas the female is larger (up to 60 mm) with a deeper body, the anal fin unmodified and when pregnant, a gravid spot is visible just above the vent (Lloyd, 1987). The fish are mostly translucent grey with a bluish sheen on their sides with a silver belly (Lloyd, 1987). The fins are colourless, with transverse rows of black spots. Some male mosquitofish have irregular black blotching, though some largely melanistic male individuals exist but are uncommon in their native range (Sterba, 1962) and are absent from Australia (Lloyd, 1987). On the male, the anal fin is modified to form a long, thin intromitent organ, the gonopodium, used for sperm transfer (Lloyd, 1990c). The body is slightly compressed with a large and flattened head. The eyes are large, and the mouth is small and terminal (Lloyd, 1987).

History of Introduction and SpreadTop of page
G. holbrooki were first introduced to Brisbane in 1925 and Sydney the following year (Wilson, 1960). The distribution of the Australian populations has continued to expand through new invasions (such as Northern Tasmania) or in filling of locations within catchments. Gambusia was actively introduced by health authorities to new locations in Australia until the 1990s (Lloyd, 1987).
Risk of IntroductionTop of page
HabitatTop of page
The native habitat of mosquitofish is the lowland ponds, lakes and streams of southern <_st13a_country-region _w3a_st="on"><_st13a_place _w3a_st="on">USA (Casterlin and Reynolds, 1977). Mosquitofish are particularly adapted to exploiting inundated floodplains (Ross and Baker, 1983). G. holbrooki is abundant in near-shore environments, close to dense vegetation, and prefers sluggish waters to running water (Lloyd, 1987). Other habitat preferences include: shallow water, dark-coloured substrata, and subsurface vegetation (providing lateral rather than vertical concealment) (Casterlin and Reynolds, 1977; Arthington and Marshall, 1999). They are very adaptable and will live in almost aquatic habitats from fresh to hyper-saline, cold temperate to tropical waters (and artificially heated waters), inland, coastal and estuarine waters, and both still and slow-flowing waters. The species does seem to be poorly adapted to fast flowing waters which inhibits its ability to develop large populations (Lloyd, 1987).

Biology and EcologyTop of page
Disturbed environments are prone to invasion from this species due to the fact that disturbed habitats can support large populations of invertebrate species (which tend to be pests, e.g. chironomids) and often lack other fish “due to harsh physical conditions” (Lloyd, 1987). Mosquitofish are typically more resistant to pollutants, including organic wastes, herbicides, insecticides, rotenone, phenols, heavy metals and radiation, than most other fish (Lloyd, 1987; Edwards, 2005). The ability of the species to survive genetic ‘bottle-necks’ and their ability to physiologically and genetically adapt to different environments is also important in their spread and success.
Mosquitofish have invaded a wide range of habitats throughout the world including: hot springs, rivers, streams, lakes, swamps, billabongs, cooling pondages, rice fields, ornamental ponds, estuaries, near-shore marine habitats and salt lakes (Lloyd, 1987; Arthington and Lloyd, 1989).
Mosquitofish are found in waters from 0.5°C to 39°C, with a preference for warm waters of about 25°C (Otto, 1974), though Pyke (2005) suggests that mosquitofish prefer water temperatures between 31-35°C. Juvenile mosquitofish are more thermally tolerant than adults, allowing them to colonise and exploit warm patches of the environment with increasing growth, survival, and maturation rate. Mosquitofish can inhabit ice-covered waters (Hirose, 1976;Sasa and Kurihara, 1980) in Japan and hot bores (over 37°C) in central Australia (John Glover, personal communication, cited in Lloyd, 1987).
Mosquitofish can tolerate oxygen concentrations as low as 1.3 mg/L, without access to surface water but can withstand virtual anoxia by utilising of the oxygen-rich surface water/air interface because it has a dorso-ventral mouth (Lewis, 1970).

Natural enemiesTop of page
Means of Movement and DispersalTop of page
Mosquitofish have become the most widely distributed freshwater teleosts in the world (Krumholz, 1948) mainly through deliberate human introductions (e.g. Lintermans, 2004). Throughout the world, G. holbrooki and G. affinis have been widely distributed to aid mosquito control in rice paddies and natural waters. (Krumholz, 1948; Lloyd et al., 1986; Arthington and Lloyd, 1989). Worldwide introduction of Gambusia has occurred since the first introduction into <_st13a_state _w3a_st="on"><_st13a_place _w3a_st="on">Hawaii in 1905 (Krumholz, 1948).
Gambusia are cited to be used in the commercial aquarium industry (www.fishbase.org) but poor sales are likely given its noxious status in many countries, its aggressive behaviour, and its poor appearance. They are likely to be under aquaculture in the <_st13a_country-region _w3a_st="on"><_st13a_place _w3a_st="on">USA for use for mosquito control in rice fields. Mosquito control authorities have been known to transfer mosquitofish between locations. Children may also collect mosquitofish for bait and help to distribute it when they move from one place to another.

Environmental ImpactTop of page
Impact on Biodiversity
In Australia, and possibly other parts of its introduced range, G. holbrooki faces few predators, parasites, diseases or competitors (Lloyd, 1987). Experiments have shown that several Australian native fish predators actively avoid eating this mosquitofish (Lloyd, 1987).
Gambusia occupy the specialized dystrophic habitats of one restricted and two endangered Australian freshwater fishes - Rhadinocentrus ornatus, Pseudomugil mellis, Nannoperca oxleyana (all found in South-eastern Queensland). It is possible that G. holbrooki and the three species interact and compete for habitat, food and spawning areas (Howe et al., 1997; Arthington and Marshall, 1999; Knight and Arthington, 2008).

Uses ListTop of page
- Biological control
- Laboratory use
- Pet/aquarium trade
DiagnosisTop of page
Genetic techniques have been used to distinguish G. holbrooki and G. affinis in Australia.
For information on the morphology of G. holbrooki please see this species' factsheet on FishBase.
Prevention and ControlTop of page
All of these measures have been applied to prevent the spread of Gambusia in Australia. The Australian Quarantine Inspection Service (AQIS) has listed G. holbrooki as a high-risk species, highly likely to establish and spread more widely once introduced to new areas (Arthington et al., 1999). Predation by G. holbrooki has been listed as a key threatening process under the New South Wales Threatened Species Conservation Act 1995. The inappropriate spread of Gambusia by humans for the purpose of mosquito control remains a problem in spite of repeated cautionary advice over the past 20 years (Arthington and Lloyd, 1989). Gambusia has been recognised as a potential vertebrate pest in Australia and as such should be managed under the edicts of vertebrate pest policies, programmes, and legislation (Bomford, 2001; Bomford and Glover, 2004).
