Swing and a miss: plenty of fish, but no Asian carp

Chicago, Ill. — There were lots of fish – 40 different species
in all – but not a single Asian carp.

The state’s most expensive fishing trip ended a few days ago, a
poisoning operation aimed at rooting out the voracious Asian carp
in a Chicago-area river, without turning up any of the unwanted
fish, DNR reported Monday.

Officials said more than 100,000 pounds of dead fish had been
collected since the poisoning five days ago. They say the operation
suggests few if any Asian carp are near a shipping lock that
Michigan and neighboring states want closed for fear it could
provide an opening to Lake Michigan. Scientists had detected
genetic material from the carp in the area.

Federal agencies and DNR spread Rotenone, a chemical toxic to
fish, along a 2.5-mile section of the Little Calumet River on
Chicago’s South Side on Thursday.

They also temporarily closed the T.J. O’Brien Lock and Dam,
despite objections from shippers whose vessels regularly use the
structure. It will reopen in a da y or two, DNR spokesman Chris
McCloud said.

Fish representing more than 40 species were found after the
poisoning, but no bighead or silver carp – Asian varieties that
have been migrating up the Mississippi and Illinois rivers toward
the Great Lakes for decades.
