Welcome

Welcome to InvasiveCarp.us, where you can find up-to-date information on ongoing efforts to prevent invasive carp from becoming established in the Great Lakes and beyond. We invite you to learn more about the work of federal, provincial, state and local partners as we join together to prevent the spread of these destructive fish.
