The article discusses how previous studies have suggested that low food levels in Lake Michigan would prevent the invasive species of Asian Carp from establishing in the Great Lakes, however, these studies do not consider that these carp are opportunistic feeders.

They can feed on a combination of phytoplankton, zooplankton, and fecal matter from mussels, which is enough for them to survive and even gain weight and thrive in the Great Lakes.
