The eastern mosquito fish (Gambusia holbrooki Girard, 1859),
is an invasive fish species and has a widespread because of biological
struggle against mosquitoes in many water sources. However, it has
negative impacts on competition with native fishes. Gambusia holbrooki
predator on native fish larvae, eggs and their own larvae (cannibalism).
This invasive fish species has a negative impact on the endemic tarek
(Alburnus tarichi, Guldenstaedt 1814) and other fish species in the region.
It is crucial for this invasive extent from Van Reeds to other water sources
in the basin to ensure the continuity of native fish species found in these
water sources. It is forbidden by the relevant institutions to transport and
adding to other water resources of this species that spread in many water
sources in our country. Here, it is aimed to evaluate ecological and
biological properties and the negative effects on other species of Gambusia
holbrooki spread in Turkey and the World.
