Invasive fishes are rapidly becoming a primary challenge to fisheries managers worldwide. There does not seem to be any watershed or ecosystem that is not seriously threatened. The taxonomic variety of fishes that are invasive, the damage they cause, and reasons for their invasiveness are also extraordinarily diverse. Yet, common lessons can be drawn from different species and situations about how to study and control these species. This symposium seeks to identify these lessons by examining species from across the world (ex. Sea lamprey, common carp, Asian carp, brown trout, smallmouth bass, etc.), locales (Great Lakes, Mississippi basin, Australia, Japan, etc.) and approaches to control (ex. toxins, behavioral barrier, predators, integrated control) in new and integrative manners. A broad range of integrative ideas and approaches are solicited. Sub-symposia on special issues such as Asian carp are possible.
