Mosquitofish Introduced to Hawaii in 1905 Now Threatens Native Freshwater Species
The eastern mosquitofish, introduced to Hawaii in 1905 to control mosquitoes, has become an invasive species threatening native freshwater wildlife. It preys on native damselflies and competes with endemic gobies and crustaceans, contributing to declines in several species. Its rapid reproduction and adaptability complicate control efforts. Conservation initiatives focus on protecting vulnerable habitats and preventing further spread to safeguard Hawaii's unique aquatic ecosystem.
