The Nonindigenous Occurrences section of the NAS species profiles has a new structure. The section is now dynamically updated from the NAS database to ensure that it contains the most current and accurate information. Occurrences are summarized in Table 1, alphabetically by state, with years of earliest and most recent observations, and the tally and names of drainages where the species was observed. The table contains hyperlinks to collections tables of specimens based on the states, years, and drainages selected. References to specimens that were not obtained through sighting reports and personal communications are found through the hyperlink in the Table 1 caption or through the individual specimens linked in the collections tables.

Common name: Blacktip Jumprock

Taxonomy: available through www.itis.gov

Identification: Page and Burr (1991); Jenkins and Burkhead (1994). The genus Moxostoma was revised by Smith (1992), and Scartomyzon, a subgenus of Moxostoma, was elevated to genus. However, Harris et al. 2002 suggest that Scartomyzon is not a distinct lineage and its species are within the Moxostoma lineage (Nelson et al., 2004).

Size: 19 cm.

Native Range: Atlantic Slope drainages from Chowan River, Virginia, to Neuse River, North Carolina (Page and Burr 1991; Jenkins and Burkhead 1994).

Alaska	Hawaii	Puerto Rico & Virgin Islands	Guam Saipan

Means of Introduction: The population in the New drainage is thought to be a result of bait bucket introduction from the Roanoke or James drainages. This population was originally thought to have reached Craig Creek by stream capture, but more recent records of collections above and below the creek suggest human introduction (Lee et al. 1980 et seq.). Jenkins and Burkhead (1994) give evidence for introduced status, but suggest no means of introduction for the Craig Creek population.

Status: Established in Virginia.

Impact of Introduction: The impacts of this species are currently unknown, as no studies have been done to determine how it has affected ecosystems in the invaded range. The absence of data does not equate to lack of effects. It does, however, mean that research is required to evaluate effects before conclusions can be made.

Remarks: None.
