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: Some believe that the Fallfish may not have been present in the Adirondacks of New York before canals and associated waterways were constructed (Smith 1985). As such, Smith (1985) indicated its presence is possibly the result of introduction, perhaps by way of the Erie Canal system or by bait bucket dumping. Smith did not speculate or provide details on its method of introduction into Tonawanda Creek, New York; that population may also have originated through bait bucket release. Jenkins and Burkhead (1994) strongly suspected that the source of the Falling River population in Virginia started with fish introduced from the adjacent James drainage. Presumably these introductions were a result of bait bucket release as well. Illegally introduced into California (Moyle 1976a).

Status: Established, possibly introduced, in the Adirondack Mountains, New York (Smith 1985); established in Falling River, Virginia (Jenkins and Burkhead 1994); reported from Tonawanda Creek, New York (Smith 1985).

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: This species is known to hybridize with Luxilus cornutus (Scott and Crossman 1973).
