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: Intentional stocking for sportfishing.

Status: Established in most locations.

Impact of Introduction: In California, aggressive Bluegill outcompete native Sacramento perch Archoplites interruptus (Moyle et al. 1974; Moyle 1976). Bluegill may chase Sacramento perch away from spawning areas and out of favored places, such as shallow weedy areas, and into open water (Moyle 1976). Once in open water, the perch are more vulnerable to predation and have less available food. Introduced predatory centrarchids are likely responsible for the decline of native ranid frogs in California, California tiger salamander Ambystoma californiense populations (Hayes and Jennings 1986; Dill and Cordone 1997), and the Chiricahua leopard frog Rana chiricahuensis in southeastern Arizona (Rosen et al. 1995).

Hybridizes with green sunfish, redear sunfish, redbreast sunfish, and warmouth (Scribner et al. 2001).

Remarks: Bluegill are commonly stocked as forage for largemouth bass in farm ponds. Because introduced California Bluegill are typically small, possibly due to a limited genetic background, the California Department of Fish and Game began introducing Bluegill from Florida in an effort to obtain a larger, faster-growing fish (Moyle 1976). Tyus et al. (1982) gave a distribution map of the this species in the upper Colorado basin.
