Data from: Mature male parr contribution to the effective size of an anadromous Atlantic salmon (Salmo salar) population over 30 years
We describe temporal changes in the genetic composition of a small anadromous Atlantic salmon (Salmo salar) population from South Newfoundland, an area where salmon populations are considered threatened (COSEWIC 2010). We examined the genetic variability (13 microsatellite loci) in 869 out-migrating...
