Means of Introduction:
Beginning in the late 1800s, there have been many stockings of this species for sportfishing purposes by state and federal agencies and by private individuals, mostly into streams and spring branches. Some states stock on an annual basis.
Status:
Established in many states, including
Impact of Introduction:
The rainbow trout hybridizes with other, more rare trout species, thereby affecting their genetic integrity (Lee et al. 1980 et seq.; Rinne and Minckley 1985; Page and Burr 1991). In
Stocking of hatchery rainbow trout in rivers has led to introduction of whirling disease into open waters in approximately 20 states including, most recently, the Madison River and its tributaries in
