Impact of stocked rainbow trout on resident salmonid populations: scoping study

A full literature review of the impact of rainbow trout on native sahnonid species has been carried out.



The literature review revealed that extensive introductions of the species have taken place throughout the world and that in sorre areas self-sustaining populations have been generated which have had severe impacts on native sahnonids. In Britain, although there are a number of instances of wild breeding only two examples of self- sustaining populations have been recorded.
