Tucker, J. K., F. A. Cronin, R. A. Hrabik, M. D. Petersen and D. P. Herzog (1997). Bighead carp Hypophthalmichthys nobilis in the Mississippi River. Unites States Geological Survey Long Term Resource Monitoring Program, Report LTRMP97-R014.
The authors report collections of the bighead carp, Hypophthalmichthys nobilis (Richardson, 1845), in the Mississippi River in Missouri and Illinois between 1991 and 1994. In all, the authors collected 48 specimens ranging from 18 to 790 mm total length. Young-of-the-year fish were caught in 1992 and 1994, which suggests 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 cyrinellus, and gizzard shad Dorosoma cepedianum. Further research is needed to confirm that the species is established and what its biological impact will be.
