摘要：	It has been estimated that at least 7,000 different species are being carried in ballast tanks around the world and that roughly 21 billion gallons of foreign ballast water are annually discharged into U.S. waters (Global Ballast Water Management Programme). While commercial ports represent a main entry point for many species introductions, very few have been surveyed to document the nonindigenous flora and fauna present. One region for which information is particularly lacking is the South Atlantic Bight (Cape Hatteras, North Carolina to West Palm Beach, Florida). This region currently has many of the largest and fastest growing container and automotive ports in the nation. Trade growth is predicted to continue, particularly with Asia. Baseline surveys are critical if we are to reduce the risk of aquatic nuisance species being introduced and transferred to and from this region. Our results will be useful in evaluating regional differences in invasion rates and patterns. Information will be shared with the Smithsonians National Ballast Water Information Clearinghouse, the Aquatic Nuisance Species Task Force, and the USGS Nonindigenous Aquatic Species Program, coastal natural resource managers, and the respective port authorities. / Supplementary Notes: Prepared in cooperation with North Carolina Univ. at Wilmington.
