Marine Scotland Science has published findings of a study looking at the behaviour of homeward migrating salmon in the ICES Journal of Marine Science.
The study is part of a research programme, funded by the Scottish Government, which aims to identify and minimise any disruptions to wildlife as the marine renewable energy industry develops.Using coastal nets on the Northern coast of Scotland, 50 large salmon were captured as they returned to their home rivers to spawn. They were fitted with data recording tags that logged depth, temperature and light levels at frequent intervals and were programmed to detach from the fish during a period of 10 days and float to the surface. The tags then relayed their locations, and the recorded data, via satellite, to the Freshwater Fisheries Laboratory at Pitlochry.
