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: Rough Silverside

Taxonomy: available through www.itis.gov

Identification: Smith (1985); Robins and Ray (1986); Hubbs et al. (1991); Menhinick (1991).

Native Range: Marine; eastern North America along the Atlantic and Gulf coasts from New York to northern Mexico (Robins and Ray 1986).

Interactive maps: Point Distribution Maps

Means of Introduction: Intentionally stocked as forage for sport fish in the three reservoirs mentioned above; uncertain about its occurrence in the Brazos River, as well as, the Red River and nearby counties. Possibly bait release.

Status: Established in all localities except the the Brazos River, where the status is unknown.

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.
