Published and unpublished data on genetic variation at the transferrin locus ( TF *) in Atlantic salmon from rivers in eastern North America sampled from 1968 to 1970 were reanalysed and compared with data for samples collected in 1998 from nine of the same rivers. Genetic differentiation among rivers was highly significant as was spatial differentiation among tributary samples within the Miramichi River system, the largest rivers studied. Comparison of allele frequencies in rivers also sampled in 1998 show no overall evidence of significant genetic change after 30 years, spanning 9 generations. The results strongly support the stability of the patterns of spatial genetic differentiation and support the occurrence in Atlantic salmon of reproductive isolation among rivers and among tributaries within large river systems.
