The Michigan attorney general is planning to go to court to try to force the closures of the Chicago Sanitary and Ship Canal. However, that would shut off a busy shippiong route to the Mississippi River, disrupting the movement of millions of tons of iron ore, coal and other goods.
While the battle over closing that canal brews, fishermen in Chicago's Calumet Sag Channel near the O'Brien Lock are using 2,000 yards of net to search for Asian carp in that 5.5-mile stretch of water.
They began looking for the fish - which can grow up to 100 pounds and four feet- on Saturday. The last of the nets should be pulled by Monday afternoon.
Those involved in the netting are from both federal and commercial fisheries. Officials do not plan to poison fish in the Cal-Sag channel because the carcasses wouldn't surface in cold waters.
