Common carp and Koi (decorative carp) thrive in turbid rivers and lakes. They are omnivorous, eating insects, crustaceans, annelids, molluscs, and seeds from weeds and trees. For the most part they grub in the sediments to find food, stirring up sediments and increasing turbidity. Adults will uproot and destroy aquatic vegetation, which may be detrimental to ducks and other fish populations. There are carp in many lakes in the state, and people are encouraged to fish for them. They are not to be put back into any waters of the state. We would like to diminish these populations.
