Abstract:
This Salmon Advisory Committee publication examines the various influences on wild salmon stocks. These are numerous and varied, both in their nature and extent. This report also concentrates on activities which can affect the emigrating smolts and returning adults in fresh water and estuaries. In it we set out to highlight the importance of minimising adverse impacts upon the fish by explaining the possible consequences of various forms of human activity which can affect survival and seriously disrupt the natural movement of fish to and from the sea. In the past the upstream progress of adult salmon in many rivers has been impeded by man’s activities, even to the extent of destroying the stocks in individual rivers. More recent efforts to improve water quality and open up access have greatly helped some rivers and resulted in the return of salmon to others, but the situation could easily be reversed and stocks would once more be lost.
