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.

Means of Introduction: Probable bait bucket introduction (N. Burkhead, personal communication).

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: Jenkins and Burkhead (1994) believe the Orangefin Madtom was introduced into the upper James drainage, Virginia, based on several factors: the species has only recently been recorded from the area, it is absent from good habitat elsewhere in the drainage, and it is a popular bait fish. In addition, Craig Creek is well used by anglers, and the site is near the upper Roanoke, a possible source of bait. The Orangefin Madtom is proposed for federal listing (U.S. Fish and Wildlife Service 1994a).
