Athabasca Rainbow Trout are threatened by several anthropogenic factors including impacts of invasive species introgression that is the transfer of genetic information from one species to another as a result of hybridization between them and repeated back-crossing with stocked Rainbow Trout mortality related to fishing sedimentation habitat fragmentation and industrial. Native to western North America from Alaska to the Baja Peninsula Oncorhynchus mykiss have been introduced to numerous countries for sport and commercial aquaculture.

Athabasca Rainbow Trout are threatened by several anthropogenic factors including impacts of invasive species introgression that is the transfer of genetic information from one species to another as a result of hybridization between them and repeated back-crossing with stocked Rainbow Trout mortality related to fishing sedimentation and habitat fragmentation.
