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: Many introductions likely were the result of contaminated stock (Sigler and Miller 1963; Hubbs and Miller 1965; Moyle 1976a, 1976b). In Utah, Rainwater Killifish arrived as a stock contaminant in a shipment of largemouth bass (Sigler and Sigler 1987). In northern California and Oregon, Rainwater Killifish may have been transported as eggs on planted oysters (Hubbs and Miller 1965; Moyle 1976a, b) or with ballast water from the Atlantic Coast (Hubbs and Miller 1965). In southern California it was a contaminant in a shipment of largemouth bass (Hubbs and Miller 1965; Moyle 1976b). Hubbs and Miller (1965) indicated some introductions may have resulted when the species was stocked along with Gambusia during mosquito control operations or from aquarium release, but that these routes were less likely than stock contamination. Most of the original introductions in the western United States apparently occurred during the 1940s and 1950s (Hubbs and Miller 1965). The species was introduced into the Great Swamp in New Jersey in 1969 (Stiles 1978) and into Texas in about 1980 (Hubbs et al. 1991), but the reasons for these introductions were not given.

Status: Established in California, New Mexico, Oregon, Texas, and Utah. Unknown for Nevada (see Remarks) and New Jersey.

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: Hubbs and Miller (1965) reviewed the introduction history of this species and provided a map distinguishing introduced and native records.

This species may not have introduced to Nevada. Hubbs and Miller's (1965) map shows the location of Blue Lake as on the Nevada-Utah border south of Wendover, UT. Subsequent authors summarizing the distribution of L. parva may have misinterpreted this location as residing in Nevada. Both Deacon and Williams (1984) and Vinyard (2001) give the distribution as "in the Blue Lake area near the Utah border, Elko County" but list no references or museum voucher specimens. Duggins in Lee et al. (1980) cites Hubbs and Miller (1965) as a reference for the species occurrence in Nevada, but Hubbs and Miller do not describe any collections from Nevada. We are unable to locate any voucher specimens from Nevada.
