A newly released study says if Asian carp reach Lake Michigan, they probably would find enough food to spread far and wide. Some experts have questioned whether there’s enough plankton in the lake to sustain the invasive carp away from shoreline areas. But the new report released Monday, Aug. 12, 2019, by University of Michigan scientists says despite a drop-off of plankton caused by exotic mussels, the voracious carp could feed on other organic material when venturing into deeper waters.
