They are used to prevent the spread of West Nile Virus, which relies on mosquitoes to migrate. However, introducing goldfish has often had negative consequences for local ecosystems.

Famous quotes containing the word control:
“Knowledge in the form of an informational commodity indispensable to productive power is already, and will continue to be, a major—perhaps the major—stake in the worldwide competition for power. It is conceivable that the nation-states will one day fight for control of information, just as they battled in the past for control over territory, and afterwards for control over access to and exploitation of raw materials and cheap labor.”
—Jean François Lyotard (b. 1924)
