The importance of salmon to people who lived in the Highlands between the 15th and 19th Centuries is to be explored.

The University of the Highlands and Islands has set up a PhD studentship to explore the consumption of the fish, and also customs associated with it.

UHI said health benefits linked to eating salmon appeared to have been recognised throughout history.

It said the Gaelic legend of Fionn Mac Cumhaill makes reference to the “Salmon of Knowledge”.
