摘要：

This study describes the genetic variation (based on analysis of 24 protein-coding genes) within and between two natural salmon populations of Asturian rivers. Information on the genetic structure of populations at the southern distribution limit of Salmo salar in Europe is provided. In the natural populations, five of 24 protein-coding loci were polymorphic (Aat-2, Idh-3, Mdh-3,4, Sdh-1 and Sdh-2). Non-significant allele frequency differences were found between populations. At the Mdh-3,4 locus the frequency of the 87 allele is much higher than the values given for other European populations. The mean heterozygosity in these samples (based on 24 loci investigated) was 2.18%. Nevertheless, the amount of variability in Asturian natural populations is somewhat lower than the average estimated in the Atlantic salmon population.
