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.

Nonindigenous Occurrences: Nile perch were imported to Texas in 1975 for research and had been stocked in Coleto Creek Reservoir in 1981 (Howells 1992a, 1992b) and in Smithers Reservoir in 1985 (Howells and Garrett 1992; Howells 1992a, 1992b) when the research ended.

Means of Introduction: Intentional stocking by the Texas Parks and Wildlife Department for sport fishing.

Status: It is believed that both stockings failed, since there have been no recent recoveries (Howells 1992a, 1992b).

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.
