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: Unintentional in most locations. It is believed that introduced channel catfish and bullhead stock was contaminated with Tadpole Madtoms (Linder 1963; Taylor 1969; Simpson and Wallace 1978; Wydoski and Whitney 1979; Hartel 1992).

Status: Established in Connecticut, Idaho, Massachusetts, New Hampshire, Ohio, Oregon, and Washington; reported in Nebraska and Texas.

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: Introduced populations in Washington resulted from the downriver dispersal of fish introduced into Idaho rivers (Wydoski and Whitney 1979). The Tadpole Madtom has not been collected from the Thames drainage in Connecticut (B. Gerrish, personal communication). Record from a lake near Poteau, Oklahoma, may be the result of an introduction (Taylor 1969).
