The authors report collections of the bighead carp, Hypophthalmichthys nobilis in the Mississippi River in Missouri and Illinois between 1991 and 1994. In all, 48 specimens were collected ranging from 18 to 790 mm total length. Young-of- the-year fish were caught in 1992 and 1994, which suggested that the species is able to reproduce in the Mississippi River and may become established. Because H. nobilis is a low-level filter feeder, its presence may affect other filter feeding fishes such as the paddlefish Polyodon spathula, bigmouth buffalo Ictiobus cyprinellus, and gizzard shad Dorosoma cepedianum.
