A four-day search for evidence of Asian Carp was announced last week after genetic traces of the invasive species was found in a Chicago lake. 
From the Detroit Free Press
“The Asian Carp Regional Coordinating Committee’s plan calls for what it calls a Level 1 response following three consecutive rounds of Asian carp DNA being detected in Lake Calumet. A Level 1 response adds to the regular monitoring both commercial fishing crews as well as added craft that use electrical shocks to stun and capture fish. There will also be larger sweeping nets used and additional sampling gear over a four-day period beginning Tuesday.”
