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: Lachner and Jenkins (1971) stated that collections from Elkhorn Creek of the lower Kentucky River system may represent introduction via bait fishermen or transport through stocking programs and farm pond culture. Smith (1985) suggested that its presence in the Susquehanna and Mohawk rivers of New York may be the result of dispersal through artificial canal systems (Chenango Canal). There are no historical records of Nocomis biguttatus from the Susquehanna drainage (Lee et al. 1980 et seq.). Consequently, Gilbert (personal communication) agrees that the species has been introduced there. However, since it has only appeared in that drainage very recently, Gilbert concluded that its presence is more likely the result of a bait bucket transfer rather than migration through the canal system.

Status: Established in Kentucky and New York in areas outside its native range.

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: There is uncertainty concerning the native versus nonnative geographic distribution of this species. According to Gilbert (personal communication), it would be virtually impossible to determine whether or not this species was introduced or originally native in the Mohawk system of New York. In their summary table of Kentucky fishes, Burr and Warren (1986) listed this species as "regarded as native, but possibly introduced" in the lower Kentucky River system of Kentucky. In their zoogeographic analysis, Burr and Page (1986) listed this species as "regarded as native, but possibly introduced" in the Kentucky River system. Page and Burr (1991) included the lower Kentucky River system as part of the range of this species. These authors did not comment ion the possibility of introduction. Welsh et al. (2013) added this species to the fauna of West Virgina through the discovery of previously misidentified museum specimens from the Little Kanawha River drainage, and indicated that although it is likely native to the state the possibility of introduction cannot be ruled out. Welsh et al (2013) also suggested that if this species was native to the Little Kanawha River drainage, then this would likely indicate an indigenous status in the Kentucky River drainage.
