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: The introduction of the Blacktip Shiner into the Mobile basin of Alabama is the result of artificial diversion of the Conecuh River (Lee et al. 1980 et seq.). All information on the appearance of this species in the Ocmulgee system of Georgia came from Bart et al. (1994). According to those investigators, the species may have been introduced to the upper Ocmulgee system either by stream capture from the Flint River, or by bait bucket release. In any case, because the species is restricted to the river reach above High Falls dam, it was likely introduced after 1904, the year of dam construction. The first record of this species in the Ocmulgee River system (and in the Atlantic Slope) is based on the collection of sixteen specimens taken during the period 1988-1990 from the headwaters of the Towaliga River system, a small western tributary of the Ocmulgee River (Bart et al. 1994).

Status: Established in Georgia. A single collection was recorded in Alabama.

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: In their summary table on Alabama fishes, Mettee et al. (1996) listed this species as native to the Tallapoosa River system.
