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: Fringed Flounder

Taxonomy: available through www.itis.gov

Identification: Fischer et al. (1995b).

Size: 20 cm.

Native Range: Marine; Gulf of California south to Panama on the Pacific coast (Ramirez-Hernández and Gonzales Pages 1976; Fischer et al. 1995b), and Chesapeake Bay, northern Gulf of Mexico, and the Antilles to Brazil on the Atlantic coast (Ramirez-Hernández and Gonzales Pages 1976; Robins and Ray 1986).

Interactive maps: Point Distribution Maps

Means of Introduction: Intentionally stocked with fish from San Felipe, Mexico, on the Gulf of California (Walker et al. 1961).

Status: The introduction failed to produce a viable population and the species is extirpated in the Salton Sea (Walker et al. 1961)

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.
