There ARE strippers in Colorado.
Nonindigenous Occurrences: Striped bass have been widely stocked in nonindigenous waters from New York to California.

Means of Introduction: Intentionally stocked for sportfishing. Some records involved fish dispersed to other areas far from point of original introduction, for instance, downstream of reservoirs after passage over or through dams (e.g., Pflieger 1997).
Status: Reported as locally established in many states. Annual stocking of lakes and reservoirs maintains the sport fishery. Attempts to establish this species in the Youghiogheny River, Pennsylvania, failed (Hendricks et al. 1979). Not established in Colorado (Walker 1993). Not established in the Great Lakes (Cudmore-Vokey and Crossman 2000).
Impact of Introduction: Preys on small fishes. Bailey (1975) summarized what was known about impacts of stocked striped bass on clupeids in lakes and reservoirs in the Southeast. Maumelle Reservoir, Arkansas, had a possible reduction in clupeids; Toledo Bend and D'Arbonne reservoirs, Louisiana, had slight reductions; J. Percy Priest Reservoir, Tennessee, had a significant reduction; and Hunter land Julianna reservoirs suffered drastic reductions. Morgan and Gerlach (1950) reported finding numerous trout and salmon fry and fingerlings in striped bass stomachs at Coos Bay, Oregon.
Remarks: The Striped Bass is a highly prized sportfish. Bailey (1975) provided a table of locations, numbers, and factors affecting success of Striped Bass stocked in the Southeast, and the outcome. Setzler et al. (1980) provided a biological synopsis of this species. Some introductions in native range are of fish from another area, i.e., Atlantic Slope fish stocked in Gulf tributaries. Boschung (1992) states that native stocks probably no longer exist in Alabama except in the Chattahoochee drainage, having been replaced eslswhere by Atlantic coast stocks.
Nobriga et al. (2013) examined the effects of juvenile Striped Bass on Delta Smelt (Hypomesus transpacificus) population dynamics, finding no correlation between between juvenile bass abundance and smelt survival and low estimates of consumption of smelt by juvenile bass.
Matlock (2014) discusses the historical status (native vs. non-native) of Striped Bass in Texas, and the potential policy implications.
