CLEVELAND -- The search for invasive Asian carp in Lake Erie has moved to the Sandusky River in northern Ohio.
Crews from Ohio and Michigan and the U.S. Fish and Wildlife Service checked the river north of Fremont on Tuesday with nets and electro shocking gear.
They were tipped by environmental DNA samples that hinted at carp. The Plain Dealer says no evidence of the Asian carp was found.
Fisheries experts believe the best way to battle the Asian carp invasion is by closing the most likely gateway to the Great Lakes, the Chicago Sanitary and Ship Canal.
Under pressure from Congress and advocacy groups, the Army Corps of Engineers has promised to produce options for blocking their passage by the end of next year.
