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: Northern Hog Sucker

Taxonomy: available through www.itis.gov

Identification: Becker (1983); Page and Burr (1991); Etnier and Starnes (1993); Jenkins and Burkhead (1994).

Size: 61 cm.

Native Range: Great Lakes, Hudson Bay (Red River), and Mississippi River basins from New York and southern Ontario to Minnesota, and south to northern Alabama, southern Arkansas, and eastern Louisiana; Atlantic Slope drainages from Mohawk-Hudson River, New York, to Altamaha River, northern Georgia; Gulf Slope drainages from Pascagoula River, Mississippi, to Comite River, Louisiana (Page and Burr 1991).

Means of Introduction: Probably introduced via bait bucket in Massachusetts (Hartel 1992; Hartel et al. 1996).

Status: Reported from Alabama, Georgia, Massachusetts, and Tennessee.

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: Etnier and Starnes (1993) and Mettee et al. (1996) mapped the locations of the collections in Tennessee, but neither work lists the species as introduced. Even though Swift et al. (1986) listed this species as introduced into the Black Warrior drainage in Alabama; neither Boschung (1992) nor Mettee et al. (1996) mentioned it in that drainage. Because of its similarity to H. etowanum, specimens south of the Tennessee drainage should be re-examined. If they truly are H. nigricans, their presence in these areas is likely a result of introduction (Gilbert, personal communication). The northern hogsucker may have been introduced into the Chattahoochee drainage where it was recently collected (Lee et al. 1980 et seq.; Swift et al. 1986; Page and Burr 1991). The collection presumably is in the Georgia portion since no Alabama locations were depicted in Mettee et al. (1996). Yerger (1977) did not list this species in the Chattahoochee drainage.

Voucher specimens: UF 168048; CU 21252 (listed as H. nigricans etowanum).
