Asian Carp DNA found in Lake Erie
Officials say a three-day sweep turned up no Asian carp in Chicago's Lake Calumet, where DNA had been found repeatedly in recent months.
A federal and state plan calls for intensive searches in the Chicago waterway system whenever three consecutive rounds of sampling detect genetic material from bighead or silver carp. Authorities are trying to prevent the carp from reaching the Great Lakes and destroying the 7-billion dollar a year fishing industry. From Wednesday through Friday of last week, crews deployed over six miles of nets in Lake Calumet and used electric currents to herd fish toward them. Some nets were designed specifically for the carp. Officials say more than 63-hundred fish representing at least 30 species were caught, but no Asian carp. Meanwhile there are signs the Asian carp has reached Lake Erie. Statehouse correspondent Bill Cohen reports.
