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.

Means of Introduction: Beginning in the 1950s, several million red drum have been intentionally stocked by the Texas Parks and Wildlife Department for use as a sportfish (Howells and Garrett 1992).

Status: Because the red drum will not reproduce, Texas populations must be supplemented with repeated stockings.

Impact of Introduction: Freshwater mussels in the family Unionidae have had very poor recruitment over the past 20 or so years in Tradinghouse Creek and Fairfield reservoirs in Texas. Reproduction of these mussels may be affected by red drum feeding on juvenile mussels. Red drum, which feed heavily on mussels in marine waters, were first stocked in Tradinghouse Creek and Fairfield reservoirs in 1975 and 1984, respectively, about the time of the mussel decline. Blue tilapia also was stocked around the same time and may have contributed to the decline by eating juveniles (Howells 1995).

Remarks: Sublette et al. (1990) included this species in their list of "fishes introduced into New Mexico, now considered extirpated." However, they provided no additional information.
