Salmon research on migratory routes extremely successful Published: 30 May, 2005
THE salmon research carried out during the cruise on board Fisheries Research Vessel Scotia has returned to Aberdeen proclaiming successful and dramatic results after
researching why so few salmon survive their epic marine migrations. Charting the migration routes and distribution of salmon (in terms of both geographical position and place in the water column by day and night) should give clues about the effects of by-catch, climate change and food supply.
Dr. Shelton, said “Through the co-operation of Dr. Holst and the Fisheries Research Services Marine Laboratory, Aberdeen, we have now developed a method for surveying salmon at sea continuously and in a non-destructive way. It has proved possible to survey the upper layers of the sea continuously for fifteen hours a day and we saw nearly two hundred individual salmon. We have surveyed about 25 km2 of sea by this method and we have been able to define the migration of post smolt salmon in the Continental Shelf edge from west of Barra to north of the Wyville Thomson Ridge in the Faroe Shetland Channel. ”.
