Genetic stock identification of Atlantic salmon ( Salmo salar ) populations in the southern part of the European range
Abstract Background Anadromous migratory fish species such as Atlantic salmon ( Salmo salar ) have significant economic, cultural and ecological importance, but present a complex case for management and conservation due to the range of their migration. Atlantic salmon exist in rivers across the Nort...
