Effects of stocking at the parr stage on the reproductive fitness and genetic diversity of a wild population of Atlantic salmon (Salmo salar L.).

ABSTRACT: Captive-breeding programs are among the most adopted conservation practices to mitigate the loss of biodiversity, including genetic diversity. However, both genetic and nongenetic changes occurring in captivity can reduce the fitness of supplemented individuals, which complicate rehabilitation efforts. In the case of Atlantic salmon, the intensity of changes that occur in captivity and their impact on fitness will vary with the stocking practice adopted. In this study, we test whether salmon stocked at the parr stage have reduced reproductive success compared with their wild conspecifics and whether they contribute to increase genetic diversity in the targeted population. To do so, we use high-throughput microsatellite sequencing of 38 loci to accurately assign 2381 offspring to a comprehe
