Feature: Protecting the Great Lakes from Asian Carp

Protecting the Great Lakes from Asian Carp

If invasive giant Asian carp make it into Lake Michigan, these voracious predators could wreak havoc on the entire Great Lakes ecosystem, home to 1/5 of the world’s fresh water. Bighead and silver carp can quickly take over habitat, out-eating and out-breeding native fish. Re-establishing barriers between the Great Lakes basin and Mississippi River watershed is the most effective way to stop the carp’s advance, as well as preventing future invasive species advances.
