Part of the St. Joseph River in southwestern Michigan will be closed for two days next week, as crews test a plan for dealing with a potential Asian carp infestation.
Bighead and silver carp from Asia have been moving northward in the Mississippi River and its tributaries. None have been spotted in Michigan waters. But the state Department of Natural Resources wants to respond quickly if the invasive fish show up.
The field exercise will take place Sept. 10-11 on a two-mile stretch of the St. Joseph River, near the Jasper Dairy boating access site in Berrien County.
Crews will use nets and electrofishing to tag and release common carp and black buffalo, then attempt to catch them again. Grass carp that are caught will be removed from the river.
