We thank Dr. Petru Banarescu for his scientific insight and for allowing us to reprint his Crucian Carp images. Pingfu Chen assisted with Chinese translations. Sherry Bostick and Amy Benson assisted in various aspects of the production of the document. The manuscript was improved by the reviews of Walt Courtenay, Carter Gilbert, Bob Howells, Larry Page, Steve Ross, Todd Slack, and Bill Smith-Vaniz. Howard Jelks provided important suggestions. The following individuals kindly provided original photographs: Mark Adriaenssens, Richard T. Bryant, Noel Burkhead, Johnny Jensen, Rusty Kimble, Fang Fang Kullander, Cathy Mohilo, David Ostendorf, and Robert Rosell. Joe Tomelleri provided original artwork for the cover, and Vanessa Ramos-Munoz designed it. Lora White at the U.S. Geological Survey Leetown Science Center library provided generous assistance with retrieval of literature. Numerous representatives of local, state, and federal agencies, as well as many private citizens, industry employees, and U.S. and foreign researchers supplied information on introduced cyprinid fishes or related subjects. We are grateful for their help. The U.S. Fish and Wildlife Service and the U.S. Geological Survey provided funding for this project.
While this report was in press, we became aware of a number of new records of foreign nonindigenous cyprinids in the U.S. as follows: Carassius auratus (6 additional records), Ctenopharyngodon idella (2), Cyprinus carpio (29), Hypophthalmichthys molitrix (6), Hypophthalmichthys molitrix X nobilis (4), Hypophthalmichthys nobilis (2), Tinca tinca (1), and Leuciscus idus (1).
Most newly acquired records represent occurrences in states or drainages already covered in our maps, but a few represent occurrences in drainages not depicted in our maps. Some of these records reflect populations that have existed for some time but have only recently been reported. Others (such as the Bighead and Silver Carp) reflect expansions of these species’ rapidly growing ranges. All of the new records reported in this addendum represent species already covered in this report. To date (May 2005), no new species of foreign cyprinid has become established within the U.S. For details of these records and to access the most current information regarding ranges of foreign nonindigenous cyprinids, see our website at: http://nas.er.usgs.gov.
This addendum highlights the dynamic nature of range limits of introduced species and the difficulties involved in maintaining accurate up-to-date maps of them.
