Climate change impact on migratory Atlantic salmon being studied

Numbers of Atlantic salmon returning to Scotland’s coast have been declining since at least 1971, according Scottish government designate Marine Scotland, external.

It said approximately half of assessed salmon stocks were in poor conservation status.

Dr Samantha Beck, of Inverness UHI, said the study would help conservation efforts target the most vulnerable populations.

Brian Shaw, director of the Highlands’ Ness Salmon Fishery Board, said: “Anyone who has fished for, or studied, salmon knows that the one constant is that the runs are always changing.

“Historical run patterns have been identified but will these trends persist, given the happening, and predicted, changes in climate?

“This study is very timely and will help our understanding of the factors controlling this important aspect of Atlantic salmon ecology.”
