Disclaimer:

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.

Common name: Shortjaw Mudsucker

Synonyms and Other Names: shortjaw mudsucker

Taxonomy: available through www.itis.gov

Identification: Barlow (1961); Thomson et al. (1979). For many years G. seta was confused with G. mirabilis, from which it is believed to have evolved (Barlow 1961).

Size: 89 mm.

Native Range: Marine; G. seta is found only in the northern Gulf of California in the rocky intertidal zone (Barlow 1961; Thomson et al. 1979).

Interactive maps: Point Distribution Maps

Means of Introduction: Intentionally stocked as forage. Sixty-three fish were stocked. Stock was obtained from San Felipe, Mexico (Walker et al. 1961).

Status: The introduction failed to produce a viable population and is no longer extant in the Salton Sea.

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: None.
