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: Probable aquarium release.

Status: Established in Hawaii.

Impact of Introduction: During the summer of 1989, Xenentodon in Hawaii were preying on largemouth bass (also introduced), to the extent that the bass population appeared to be threatened (Devick 1991b).

Remarks: This species displays sexual dimorphism and spawns throughout the year in Hawaii. These needlefish apparently cannot survive outside of the reservoir and are unlikely to do well during an extended reservoir drawdown (Devick 1991b). Courtenay et al. (1991) and Robins et al. (1991b) incorrectly reported Strongylura kreffti, the long tom, as having been introduced into Hawaii based on an early tentative identification of X. cancila (W. Devick, personal communication). Voucher specimens: Hawaii (USNM 308225).
