The Atlantic salmon, Salmo salar Linnaeus 1758, is a charismatic species due to its cultural and economic importance across the North Atlantic. In addition, Atlantic salmon is one of the most well researched finfish species. However, there are still considerable knowledge gaps concerning their life history, particularly for salmon smolts migrating from rivers in the British Isles. To date management and research efforts have been largely focussed on improving and understanding salmonid migration through fresh water habitats. Despite these management efforts, Atlantic salmon populations continue to decline. This has led researchers to speculate that the decline may be related to factors encountered at sea, particularly within the early marine environment. This thesis has filled in knowledge gaps concerning the migratory behaviour of Atlantic salmon smolts migrating from rivers draining into the West Coast of Scotland and Ireland using acoustic telemetry. Despite the fresh water environment being the main ...
