7/30/11 – Federal crews will increase monitoring efforts on waterways near Lake Michigan next week. The stepped up routine comes after genetic material from the invasive carp was found in a third consecutive round of testing. Those crews will use electricity to stun fish, sweep the waterways will long nets, then take additional samples in Lake Calumet and the Calumet River. Four days of testing starts Monday. Some scientists say, if the carp establish a foothold in the Great Lakes, they could destroy the multi-billion dollars fishing industry. If a carp is found during next week’s testing, the efforts will be ramped up even more. If several are found, a toxin could be used to kill the carp.
