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: Spot

Taxonomy: available through www.itis.gov

Identification: Hoese and Moore (1977); Manooch (1984); Robins and Ray (1986).

Size: 36 cm.

Native Range: Marine. Massachusetts to northern Mexico; absent from southern Florida (Robins and Ray 1986).

Interactive maps: Point Distribution Maps

Means of Introduction: Intentionally stocked as a sport fish.

Status: The introduction failed.

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: Howells and Garrett (1992) provided no details concerning the stocking of spot in Texas. Presumably, its introduction took place in the 1950s, or shortly thereafter, when Texas agencies began wholesale capturing of native marine species along the Texas coast for later transport and stocking in reservoirs and rivers within the state.
