Abstract Ninety-one young-of-the-year Atlantic salmon Salmo salar were captured using a non-invasive snorkelling technique in a 38 m section of Catamaran Brook, New Brunswick, Canada, to test whether related fish settle closer to one another than unrelated fish. A maximum likelihood estimate of parentage relationships assessed by genotyping eight microsatellite loci revealed five half-sibling families in the sample of fish. Related juvenile S. salar were not found closer to one another than unrelated fish in three analyses at two spatial scales: a comparison of the relatedness of focal fish to their nearest neighbour and to their four nearest neighbours, and a correlation of the pair-wise relatedness and distance matrices for all fish in the sample. The lack of a kin-biased dispersion pattern may be related to the lower density of fish or the scarcity of full-siblings at the study site compared to laboratory conditions.
