An Asian carp was found for the first time beyond electric barriers meant to keep the voracious invasive species out of the Great Lakes, state and federal officials said Wednesday, prompting renewed calls for swift action to block their advance.
Commercial fishermen landed the 3-foot-long, 20-pound bighead carp in Lake Calumet on Chicago’s South Side, about six miles from Lake Michigan, according to the Asian Carp Regional Coordinating Committee.
