From the Detroit Free Press:

Federal and state agencies announced $47 million worth of new projects Thursday to combat Asian carp and prevent their spread to the Great Lakes.

The 13 projects include a new laboratory in Wisconsin that will do increased DNA sampling for Asian carp around the lakes, aiming to take 120 samples per week. Scientists also will try to find genetic markers in the fish that can be used to help determine where they are.

The agencies also are looking at 18 risky pathways from New York to Minnesota that the fish could use to get into the lakes, hoping to find ways to block them. They also will study whether steel-hulled barges passing through electrified barriers near Chicago might be providing the fish a free ride, protecting them from the electric charge that is meant to repel them.
