A mosquitofish by the lake in Victoria Park, SydneyFeature article regarding the introduction of Gambusia (Mosquitofish) to Western Australia by amateur fish breeder Ernest Prout.
The eastern mosquitofish (Gambusia holbrooki) 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.[1] 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.[2] 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.[3] Studies have shown that Gambusia can suffer mortalities if fed only on mosquito larvae, and survivors show poor growth and maturation.[1] Gambusia typically eat zooplankton, beetles, mayflies, caddis flies, mites and other invertebrates; mosquito larvae make up only a small portion of their diet.[4]
