Eastern mosquitofish, Gambusia holbrooki. Mature female eating mosquito larvae at surface. Introduced worldwide in tropical and subtropical countries. North America: Atlantic and Gulf Slope drainages from New Jersey south to Alabama in USA. Established throughout southern Europe Introduced for mosquito control. Voracious appetite for natural invertebrate and mosquito larvae. Potential pest. Have become an invasive species in Australia. Eastern mosquitofish were introduced into New South Wales in the 1920s to control mosquitoes, but provided no further benefit over small Australian native fish. Further, they cause harm to native species which have an aquatic larval stage. They are aggressive, fin-nipping harassers of other fish, and pose a serious threat to native Australian fish and aquatic fauna. Negative impacts on rainbowfish species and at least one frog species have been documented. Several rainbowfish populations appear to have become extinct due to the impacts of introduced Gambusia. Compounding the issue, Eastern mosquitofish have the ability to thrive in many different environmental conditions which are usually lethal to other fish species. Aquarium
