Feds to step up hunt for Asian carp near Chicago
CHICAGO (AP) – Federal officials say they will begin intensive monitoring of a waterway near Lake Michigan next week after genetic material from the invasive Asian carp showed up in three rounds of genetic testing.
Crews will conduct electrofishing – using electric jolts to stun fish – sweep nets and additional sampling in Lake Calumet near Chicago during a four-day period beginning Monday.
Last Friday, the U.S. Army Corps of Engineers said it had found two additional samples containing DNA from silver carp, one of two Asian species threatening to enter the Great Lakes after migrating northward from the South for decades.
Some scientists say if the large, voracious carp establish a foothold in the Great Lakes, they could starve out prized sport fish by gobbling plankton.
