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: Exactly how Brown Darters arrived to Swift Creek is not clear. It is possible that the Brown Darter spread by natural dispersal through estuaries into new tributaries of Rocky Bayou. They may have been a result of discarded bait, or they may have been present but overlooked in previous collections (U.S. Fish and Wildlife Service 1998).

Introduction at Boggy Bayou was probably via bait bucket, at least in the headwaters. Multiple bait bucket introductions may have occurred in this area (Burkhead et al. 1992; U.S. Fish and Wildlife Service 1998). Another possible means of introduction is stock contamination. In the 1950s and 1960s, certain sections of the Rocky Creek watershed were stocked with rainbow trout, largemouth bass, and smallmouth bass from the federal fish hatchery in Welaka, FL. The hatchery is located within the native range of the Brown Darter, and it is possible that Brown Darters were accidentally included in the shipment (Burkhead et al. 1992).  Lastly, this may represent a natural dispersal through estuaries.  Burkhead et al. (1994) demonstrated that this species can tolerate up to 14 ppt salinity with high survivorship.  Salinities in the bayou are in this range.

The single individual collected in Juniper Creek, a Boggy Bayou tributary, may have been the result of a bait release (U.S. Fish and Wildlife Service 1998).

Status: Established in lower reaches of Rocky Bayou stream systems; reported from Boggy Bayou. Populations fluctuate over a period of 3-5 years.

Impact of Introduction: The Brown Darter is replacing the Okaloosa darter E. okaloosae in portions of several creeks tributary to Choctawhatchee Bay (Burkhead, personal communication).

Remarks: It is debated whether the Brown Darters in Rocky Bayou represent introductions or a species that was overlooked.
