Long-term warming of the River Spey
River temperature influences biogeochemical processes and aquatic ecology. Sustaining cool river temperatures in Scotland is essential for aquatic ecology (including the habitat and health of Atlantic salmon (Salmo Salar) and brown trout (Salmo trutta). River temperatures are also critical for our economy e.g. sport fishing contributes around £113 million per year to Scottish rural economy and our food and drink industry e.g. whisky production.
