Eagles and white pelicans have been seen catching smaller adult and juvenile carp, and Largemouth bass have been seen feeding on the small juveniles. Other top predators like Great Lakes muskellunge, which are now being reintroduced to west Michigan rivers drowned rivermouth lakes, might also have the ability to prey on mature Asian carp up to a certain size. Carp fry are notoriously naive, even in the aquaculture setting and thus fry are very heavily preyed upon by a host of predators such birds, fish, and inverts. There are no known predators of the Bighead carp in the United States because it is a newly introduced species in the environment. That’s the case in the Illinois River where invasive carp comprise more than 90 percent of the weight of all fish, according to a  2017 report from the Great Lakes Sea Grant Network. With few natural predators, Asian carp dominate the waters they invade, outgrowing native predators within a year. The flathead catfish dwells in large, warm rivers of southern Michigan and often weighs 10-30 pounds. At such a size, there are no North American fish that are able to prey upon adult carp. 3,4 Asian carp are constant and voracious eaters, able to consume between 20-120% of their body mass in plankton. 3,4 There are only a few predators that are able to prey upon young Asian carp because the carp grow very fast and the window of opportunity is narrow, making natural methods of population control difficult. This is one of the reasons why carp produce up 100s of thousands of eggs in a single go.
