Spread of invasive species into Scotland: study

A horizon scanning study involving analysis of pathways of spread of invasive non-native species into Scotland. It considers species having the highest likelihood of arrival and establishment and the magnitude of their potential negative impact on biodiversity and ecosystems over the next 10 years.

5. Fishing for salmon (which includes Atlantic salmon (Salmo salar) and sea trout (Salmo trutta) is a separate heritable right from land ownership and access is controlled by those who own those rights to fish. The right to fish for species other than ‘salmon’ (such as brown trout (Salmo trutta ) relies on the provision of access by landowners and permission is required.
