An analysis of the distribution of juvenile Atlantic salmon ( Salmo salar) in nature as a function of relatedness using microsatellites
The major objective of this study was to test the hypothesis that juvenile Atlantic salmon kin occupy adjacent territories in their natural habitat in order to profit from the benefits associated with kin‐biased behaviours, as has been observed under controlled laboratory conditions.

The major objective of this study was to test the hypothesis that juvenile Atlantic salmon kin occupy adjacent territories in their natural habitat in order to profit from the benefits associated with kin‐biased behaviours, as has been observed under controlled laboratory conditions.
