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.

† Populations may not be currently present.


Means of Introduction: Unknown; probable bait bucket releases. Introduced as early as the 1950s into parts of the Rio Grande basin of New Mexico. The Rio Hondo, Mimbres, and Largo Creek introductions all occurred in the 1960s (Sublette et al. 1990).

Status: The Largo Creek population was extirpated by 1990, but the New Mexico populations in Rio Hondo and the Mimbres remain established (Sublette et al. 1990). It is locally established in a portion of the Rio Grande basin (Sublette et al. 1990). Reported but not known to be established in the Zuni River, New Mexico, and in the Virgin River, Arizona (Lee et al. 1980 et seq.). The status of the Virgin River population is unknown.

Impact of Introduction: Unknown.

Remarks: Koster (1957) reported that the species is used as a baitfish.
