Table 1.
Overview of tagged post-spawned Atlantic salmon from eleven rivers in eight geographic areas in the north-east Atlantic and maiden salmon captured off Greenland. The number of fish tagged, tagging dates and fish body size is given for each river/location each year. The number of fish with tags providing data, the total number of days recording data, mean % of the data retrieved from the tags, mean distance migrated as a straight line from the river to the pop up location, and the maximum recorded swim depth of the fish are also given. NW north-western, NE north-eastern, SD standard deviation.
