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. Introduced into the Tongue River in Wyoming and moved downstream into Montana (Holton 1990). Rock Bass were extensively stocked in Missouri by state personnel during the 1930s and 1940s (Pflieger 1997). Probably gained access to the Hudson River in New York via migration through either the Erie and/or the Champlain canals (Mills et al. 1997). They were first taken there in a 1932 survey (Mills et al. 1997).

Status: Established in most locations. Extirpated in California (Hubbs et al. 1979; Dill and Cordone 1997). Reports of Rock Bass in California after circa 1930 are apparently erroneous; see Dill and Cordone (1997) for discussion. Apparently extirpated in Idaho; Simpson and Wallace (1978) do not mention it in their book of Idaho fishes. Extirpated in Utah (Sigler and Sigler 1996). Extirpated in the Rio Grande drainage, New Mexico, and persisting only in Blue Spring in the Pecos drainage.

Impact of Introduction: Rock Bass have severely affected Roanoke bass populations in the upper Roanoke drainage through hybridization and competition (Lee et al. 1980 et seq.; Jenkins and Burkhead 1994). Roanoke bass declined after 1965, when Rock Bass reached high densities (Jenkins and Burkhead 1994). Ambloplites in eastern Oklahoma may represent hybrid forms between A. ariommus and A. rupestris as a result of intensive stocking efforts during the late 1800s and early 1900s (Cashner and Matthews 1988). Jenkins and Burkhead (1994) speculated that introduced Rock Bass may have contributed to the demise of an isolated population of trout-perch Percopsis omiscomaycus in the Potomac River in Virginia and Maryland. Nonnative predators, including Rock Bass, have been shown to reduce the abundance and diversity of native prey species in several Pacific Northwest rivers (Hughes and Herlihy 2012).

Remarks: Although Loyacano (1975) lists this species in the Santee drainage, South Carolina, he did not distinguish it as introduced there. However, his publication only distinguished species not native to the state rather than to certain drainages.
