Development of SNP markers derived from RAD sequencing for Atlantic salmon (Salmo salar L.) inhabiting the rivers of southern England

Abstract

The rivers of the Hampshire Basin, southern England contain a genetically unique group of Atlantic salmon that have suffered dramatic declines in numbers over the last 40 years. Knowledge of levels and patterns of genetic diversity is essential for effective management of these vulnerable populations. Using restriction site-associated DNA sequencing (RADseq) data, we describe the development and characterisation of a panel of 94 single nucleotide polymorphism (SNP) loci for salmon from this region and investigate their applicability and variability in both target (i.e. southern English) and non-target populations. The SNP loci will be useful for population genetic and assignment studies on Atlantic salmon within the UK and beyond.
